Closed Loop Partners Releases New Guidelines to Strengthen U.S. Recycling Operations as Extended Producer Responsibility Laws Gain Momentum in the U.S.
October 14, 2025
The new guide shares tactical best practices to help materials recovery facilities optimize recycling operations and supports industry efforts to keep more plastics, metals, glass, paper and other valuable materials in circulation.
October 14, 2025, New York, NY – Today, Closed Loop Partners’ Center for the Circular Economy (“the Closed Loop Center”), in collaboration with American Beverage, releases a new best practices guide for materials recovery facilities (MRFs) in the U.S., supporting MRFs in their work to optimize recovery rates, increase material quality and foster resilient operations. The guide, Materials Recovery Facilities: Effective Operation, Design and Management in Theory and in Practice, draws on insights from leading public and private MRF operators, recycling equipment vendors, recycling industry experts and others, establishing the industry standards needed to improve U.S. recycling infrastructure.
The guide is being released as Extended Producer Responsibility (EPR) laws gain momentum across the U.S.—with seven states already implementing them and more actively evaluating adoption. As these laws expand, there will be a growing need for transparency, performance-based metrics, and targeted education and funds to help MRFs adapt. This guide was created to aid MRF management personnel in identifying areas of improvement at their facilities and optimizing operations to maximize recovery of material streams and strengthen financial outcomes.
“The U.S. recycling industry is at a critical point, with policy changes shifting the status quo and creating opportunities for materials recovery facilities to operate at their highest capacity,” said Kate Daly, Managing Partner and CEO of the Center for the Circular Economy at Closed Loop Partners. “This guide’s insights help lay the foundation for stronger infrastructure, positioning U.S. recyclers to accelerate their critical work building resilient material supply chains.”
“Collaboration with MRF operators, commitment to high standards, innovation and transparency are essential for Producer Responsibility Organizations to achieve EPR targets,” said Jeffrey Fielkow, Chief Executive Officer, Circular Action Alliance. “Circular Action Alliance supports this playbook by Closed Loop Partners’ Center for the Circular Economy, as a practical guide for collaboration to maximize recovery and deliver program compliance and measurable results for a circular economy.”
MRFs play a critical role in managing residential recyclables, and with the right operational strategies, their recovery rates can improve dramatically. The guide outlines proven approaches to material flow design, equipment configurations, maintenance routines, municipal contract updates and staff training, among other areas. Developed through direct engagement with MRF operators—both public and private—as well as equipment manufacturers, the manual draws on site visits, real-world testing and case studies to highlight what works. This guide delivers actionable insights to help MRFs increase material capture, reduce residuals, and enhance both environmental and financial performance.
In addition to the guide itself, a set of complementary templates are available for download and can be utilized by MRFs to establish best practices in their facilities, with key guidance on areas including:
- Metrics and Performance Optimization
- Equipment Maintenance and Spare Parts Management
- Facility Management and Staff Organization
- Industry Relations
The Closed Loop Center commissioned Resource Recycling Systems (RRS) to support this work. “Materials recovery facilities are at the center of how communities recycle, and this guide equips them with clear, tactical practices to optimize performance in today’s evolving policy landscape,” said RRS Co-CEO Resa Dimino. “Through this collaboration with Closed Loop Partners and American Beverage, we’re underscoring practical ways operators can increase material capture, reduce residuals, and strengthen both environmental and financial outcomes as EPR programs expand.”
“One of America’s beverage companies’ highest priorities is creating a circular economy for our valuable, recyclable bottles and cans, and supporting the infrastructure that makes this possible,” said Kevin Keane, CEO of American Beverage. “Through this new guide, we aim to support key players along the recycling value chain to be well-positioned for success.”

Materials Matter: Designing Reuse for the Real World
August 27, 2025
This year has been marked by major milestones for reuse, with new reuse systems gaining traction across consumer goods and in retail stores across the U.S. Reuse systems have been deployed in stadiums, schools and even entire cities, yet much of its success still lies in its design.
One of the most important design decisions for reuse is selecting the right material. It’s also one of the most complex.
While it would be easier to dictate one material for all reuse systems, the reality is that there is no one-size-fits-all solution. Different materials bring different advantages—and different challenges. Each has its merits for diverse situations and locations––from durability to recyclability, customer experience and cost. The variables are many, and the tradeoffs must be considered to yield the best results.
In our work to bring reuse to market, we evaluate each material based on how well it fits into a given system: How often will it be returned? How will it be washed and stored? What will the customer do with it after use? Can it be recovered at end-of-life?
Operational logistics, return rates and customer behavior all play a role in deciding which material is most appropriate. For example, where return rates are lower, lightweight materials with a lower environmental breakeven point are more effective. Where return rates are high, more durable materials will likely have a more positive long-term impact—even if they cost more upfront.
To illustrate the complex interplay between materials and reuse systems, we explore the tradeoffs of the three most common materials for reusable packaging today: 1) plastic, 2) metal, and 3) glass and ceramic.
PLASTIC: LIGHTER WEIGHT, LOWER CARBON IMPACT

Plastics for reusable foodservice applications can range from lower-stiffness materials like HDPE or PP, to more rigid resins like PET.
The Pros
One of plastic’s key advantages is its light weight. In fact, advances in manufacturing now allow reusable packaging to be lighter without compromising performance. For example, some expanded PP designs feature a lightweight foamed core sandwiched between two solid skin layers, adding insulating air pockets while reducing material use and maintaining durability. Plastics can also withstand being tossed carelessly into a return bin, while stainless steel may dent and glass or ceramic may break. Having a lighter weight per packaging unit translates into a lower purchase cost and smaller manufacturing carbon footprint compared to metal, glass and ceramic.
In addition to the lower carbon footprint of producing lighter weight materials, the transportation footprint and cost of lighter materials is also comparatively lower. Today, plastic still offers the fastest path to environmental breakeven point for reuse, which is especially important for systems with low or unpredictable return rates.
Plastic packaging can also be molded into different shapes and colors, increasing brand differentiation and consumer appeal. Plastics are generally perceived as less premium than other durable materials––but that is not necessarily a drawback, in the case of reuse. The lower perceived value may discourage consumers from keeping the packaging forever, supporting higher return rates for returnable packaging models. However, clear communication will be required to ensure customers don’t mistake reusable packaging for single use. When plastic reusable packaging needs to be decommissioned, there is a clear pathway to ensure that these materials don’t end up in landfill. These plastics are accepted in curbside recycling in most cities, and there are strong end markets to keep recycled PET, HDPE and PP in circulation in the U.S.
The Cons
Plastic comes with messaging challenges. It can be confusing to “eliminate single-use plastics” and then replace it with another plastic item. Plastic also doesn’t tolerate heat and exposure to acidic foods as well as other materials. It may also stain or retain odors from certain foods, requiring earlier decommissioning.
Human health is also a concern with plastics. Raw material extraction, processing and manufacturing can create health concerns for workers and communities. Some consumers are starting to think more about the potential health impacts of using plastics, especially for food and beverage. While a scratch in stainless steel is typically only an aesthetic issue, a scratch in a rigid plastic product can be both an aesthetic and food hygiene issue. One concern is the consumption of microplastics, which have been found in tap water, beer, sea salt and tea. Another concern is chemical leaching from additives used to enhance plastic performance. Food-grade plastics used in packaging and foodservice applications undergo rigorous FDA testing and are approved by regulators as safe for their intended use.
In our study of consumer perceptions of different reusable hot cups, consumers expressed low interest in trying reusable clear plastic cups for hot coffee or tea, and many reported they would throw clear cups in the trash or recycling instead of returning them. Recycled plastic, however, received high interest for trial and return, and consumers showed relatively low concerns related to leaching.
In summary, plastic can play a critical role in the transition from early-stage activations to a scaled reuse economy. For programs with high reuse rates, plastic is still an option for functional and financial reasons, but metal, glass and ceramic have also become viable options.
METAL: GREATER DURABILITY, LONGER LIFE

Metal reusable packaging is often made of stainless steel or aluminum.
The Pros
Metal packaging’s key advantages include durability and the ability to provide what many consumers describe as an “improved” or “premium” experience. Metals—especially stainless steel—are incredibly durable. When used for packaging, it retains its quality through many washing cycles, making it ideal for reuse models with high return rates, such as closed-loop settings (for example, school cafeterias) and bring-your-own (BYO) programs.
Metal is also technically highly recyclable and offers a strong end-of-life pathway—if it’s captured. Aluminum is widely accepted in U.S. recycling systems and has a strong secondary market, with minimum degradation from repeated recycling (in contrast to plastic). However, metal packaging often requires linings to be compatible with many food, beverage and personal care formulas, creating recycling and washing challenges.
Stainless steel is also 100% recyclable, though not commonly accepted curbside. However, because it is a high-value material, reuse operators can potentially find recovery alternatives for decommissioned packaging via business-to-business recycling.
The Cons
The benefits of metal come with trade-offs, particularly higher financial and environmental costs.
Metals are generally more expensive than plastic, making them less affordable for some businesses and consumers. The process of mining and converting raw materials into metal is also very carbon intensive.
For certain applications, like hot or frozen items, metal packaging can be polarizing. In one study, we found that one third of consumers prefer metal cups due to insulation and perceived quality, while another third avoid them, often citing taste concerns or discomfort with how hot the cup feels. But context matters. Coffee drinkers may need double-walled steel formats that insulate well, while sport fans might prefer an aluminum cold cup to keep them cool at a summer game.
GLASS AND CERAMIC: ELEVATED EXPERIENCE, HIGH SATISFACTION
This includes packaging made of borosilicate glass, a type of glass known for its high resistance to thermal shock and chemical corrosion.
The Pros
Glass and ceramic offer an elevated consumer experience in many product categories, with consumers defining them as “aesthetically pleasing”. Both materials are well-liked for dine-in environments, in both home and retail settings. These materials are also highly stable and compatible with food and personal care products. They do not retain odors or flavors, and can be effectively sanitized across many use cycles.
If recycled glass is used, the environmental benefits are notable. Using 10% more cullet––also known as recycled glass––in glass manufacturing can save 2–3% of energy and reduce CO2 emissions by 4–10%. Reuse of glass at scale has also been used for beverage globally. In the U.S., reuse is limited but does exist in programs like Oregon’s BottleDrop Refill and local dairy operations like Straus Creamery and Oberweis Dairy in the Midwest.
The Cons
While extremely sturdy and durable overall, one drop on a hard surface, or a collision with another product can result in chips or cracks that render the product unusable. This limits the scalability of returnable programs that depend on broad consumer participation in open systems.
From a financial and environmental standpoint, glass and ceramic are also costly to manufacture relative to plastic. Both are made from widely available raw materials but have energy-intensive manufacturing processes and high transport emissions due to their weight. Forming raw materials into glass requires melting them at high temperatures, which accounts for 70% to 80% of the energy consumption of the entire manufacturing process and is typically accomplished by burning natural gas. The good news is that according to NREL, glass manufacturing emissions can be reduced by over 80% through recycled content, electrification and renewable energy. .
One major issue with ceramic is that it cannot typically be recycled—when collected, it is often downcycled into materials like brick or concrete. Glass, on the other hand, is highly recyclable, with established pathways to recover reusable glass at the end of its life, if the right systems are in place. The highest value recycled glass is collected through drop-off programs where it can be sorted by color before it breaks, as mixed color cullet is of little to no value to processors. However, U.S. recyclers face big challenges collecting and sorting curbside glass today. Small-format plastics contaminate glass streams at materials recovery facilities (MRFs)and most glass is sent to landfill. This is a key challenge that the Center for the Circular Economy at Closed Loop Partners is looking to solve through its Consortium to Recover Small-Format Packaging.
Material Fit Depends on System Design
This partial analysis illustrates the complexity involved in selecting materials for reuse systems—and the need to go beyond a static lifecycle analysis. Aligning material selection with system design is critical. Because of the complexity and relative novelty of reuse systems in many product categories, innovation and experimentation are more important than ever. As reuse systems evolve, the Center for the Circular Economy’s pragmatic, data-driven and collaborative approach will continue to reduce risk in reuse, and accelerate the scale-up of the materials and systems that work.

Beyond the Bag Initiative Unites Major and Local Retailers to Cut Single-Use Bag Waste Across Nearly 1,000 Stores in California, Reaching Over 10 Million Customers
July 29, 2025
Headlined by Target, CVS Health, Ralphs and Food 4 Less, a new consumer campaign launches across Southern California counties and invites customers to “Break Up With Single-Use Bags.”
July 29, 2025, New York, NY – In a continued push to reduce single-use bag waste, the Consortium to Reinvent the Retail Bag—an industry collaboration managed by Closed Loop Partners’ Center for the Circular Economy—has launched the largest retail campaign of its kind in California, inviting customers to “Break Up With Single-Use Bags.” Supporting the initiative are Target, CVS Health and The Kroger Co. through its local banners Ralphs and Food 4 Less.
Now rolling out in nearly 1,000 stores across Southern California, the campaign significantly expands the Consortium’s reach and marks a milestone for bag reduction and reuse, engaging and inviting more than 10 million customers to reduce single-use bag waste and build a more circular future for their communities and the retail industry.
The campaign launches at a pivotal time, as major retailers recognize the need to support customer behavior change to meet waste reduction goals. California was the selected market for the campaign in anticipation of a significant policy shift: beginning in January 2026, the state will ban all single-use and thicker plastic bags, offering paper as the only single-use bag option. This transition presents a key opportunity for impact, based on evidence that well-designed policies, paired with effective consumer engagement, can drive meaningful reductions in single-use bag waste.
“Break Up With Single-Use Bags” is an ongoing, open campaign, inviting customers and retailers to participate in vital work to shape the future of retail, one that does not create single-use bag waste. The campaign encourages people to let go of familiar––yet operationally and environmentally challenging––habits of disposable bag use, and transition toward more resource-efficient low-waste choices.
“This campaign reflects a growing movement of retailers and communities working together, guided by data and a shared vision, to shift the retail experience toward one that eliminates waste altogether by reducing our reliance on disposable bags,” said Kate Daly, Managing Partner and Head of the Center for the Circular Economy at Closed Loop Partners.
The campaign includes a major rollout across Orange County, San Diego County and the Inland Empire, with a suite of customer engagement strategies, including in-store signage, checkout prompts, parking lot signage and out-of-store marketing, all designed to engage shoppers at key decision points. The campaign’s tactics and design were informed by data and insights from the Center for the Circular Economy’s previous in-market community-wide activations, including the 2024 Petaluma Reusable Cup Project in California and the 2023 Bring Your Own Bag pilot in Denver, Colorado, and Tucson, Arizona.
The in-market tests in Denver and Tucson deployed similar strategies and resulted in statistically significant reductions in single-use bag consumption. In Denver, where bag legislation is already in place, single-use bag transactions decreased by 11.7 percent. Across both markets, the pilot was estimated to have reduced single-use bag use by approximately 9.5 million bags annually. This upcoming in-market activation in California builds on proven tactics, with an expanded scope and extended timeline—running for over a year to generate deeper insights into long-term behavior change and systems-level outcomes.
“At Target, we’re proud to offer products and services that provide our guests with more sustainable options,” said Agata Ramallo Garcia, vice president, head of enterprise sustainability at Target. “We’re thrilled to support efforts like the Beyond the Bag Initiative that offer guests convenient solutions that reduce environmental impact and make a meaningful impact for the communities we serve.”
“The health of our environment is directly connected to the well-being of the people and communities we serve,” said Jenny McColloch, VP of Sustainability and Community Impact at CVS Health. “This connection drives our commitment to creating a more sustainable future across everything we do at CVS Health. This latest initiative aims to collaboratively address waste in our neighborhoods, stores and everyday decisions, creating a positive impact for individuals and the planet.”
“At our Ralphs and Food 4 Less stores, we’re helping customers take small but meaningful steps toward reducing waste,” said Salvador Ramirez, Corporate Affairs Manager at Ralphs and Food 4 Less. “‘Break Up With Single-Use Bags’ is about more than just bags––it’s about building habits that align with the values of our shoppers and the goals of our Zero Hunger | Zero Waste plan.”
The Consortium to Reinvent the Retail Bag brings retailers and communities together to create lasting impact and learnings that can be scaled to new markets, and is inviting more retailers and community partners to join the movement. Other participating retailers include Consortium Supporting Partner Dollar Tree and independent local retailers. All retailers in the participating communities are welcome to access the free signage toolkit, activate customer prompts and take part in reshaping retail norms around waste.

Reuse Is Coming to U.S. Cities. Here’s How Businesses Can Get Ready.
July 22, 2025
Reuse is growing across sectors — but it’s still one of the toughest challenges ahead for the packaging industry. The good news is that the blueprint now exists for brands and retailers to partner with communities and build the solutions they need to meet the moment.
Reuse is not easy.
Transitioning everyday goods from disposable to reusable — products and packaging that are returned, collected, washed, refilled then redistributed — is complex. For decades, the retail industry has relied on a system where hundreds of thousands of product categories have been optimized to stay fresh and stable through supply chains, deliver a great consumer experience, and be conveniently disposed of anywhere after years of use. Moving away from this is no small feat. At a small scale, the cost of washing and collecting containers alone currently can be prohibitive. That’s before the price of the reusable container itself is factored in, divided by the number of times it’s actually reused.
Reuse is possible.
Closed Loop Partners’ Center for the Circular Economy spent the last seven years building multi-brand, multi-sector collaborations that are solving complex reuse challenges that many brands can’t tackle on their own. In Petaluma, California, the Center launched the nation’s first citywide reusable cup program, and saw consumers adopting and maintaining new reuse behaviors almost overnight. Return rates increased week by week, while costs went down. Similarly, our reuse pilots in retail stores throughout Denver and Tucson drove a significant shift in consumer behavior by rallying public and private sectors behind a commitment to move beyond single-use bags and make reduction and reuse a daily norm.
Reuse is coming to retail, and to entire cities.
Today, there’s renewed momentum — and urgency — driving the growth of reuse. New policy mandates, on top of consumer and climate pressures, are pushing brands and retailers to refocus on solutions that reduce waste. The first reuse target of SB-54, the California law that mandates packaging reduction and reuse, is effective in just 18 months. It’s no longer a question of whether brands need to build capability in reuse but how and when.
That’s why the Center for the Circular Economy is launching the Reuse Cities Initiative, the largest ever citywide reuse program in the U.S. Starting in California in 2026, the initiative builds upon the Center’s reuse work in cities across the U.S., including Denver, Tucson and Petaluma and is designed to address the two biggest barriers to scale:
- Cost — how to reduce the cost of reuse to make it viable for brands, retailers and consumers;
- Consumer behavior — how to offer consumers great options that help them build the daily habits needed to return and participate consistently.
Reuse can scale.
The Center has established an in-market implementation approach that works. In collaboration with brands, operators, municipalities and innovators, over the last seven years, we’ve already built the blueprint to shift consumer behavior and reduce system costs—now we’re applying these lessons at scale:
- Collaboration: Citywide activation and cross-sector alignment helps drive measurable behavior change;
- Supply Chain Redesign: Partnerships between brands, innovators and operators unlock shared infrastructure and logistics improvements;
- Consistent Messaging: Unified consumer messaging across partners helps reinforce trust and drive loyalty;
- Packaging Engineering: End-to-end testing to reach environmental breakeven points faster;
- Operational Alignment: Seamlessly integrating reuse into retail and foodservice environments without disrupting operations increases retailer adoption.
As an extension of the NextGen Consortium’s successful in-market reuse programming, the Center is bringing this proven framework to life through a long-term city launch in California. The timing couldn’t be better: this initiative will lay the groundwork for compliance with SB-54 by building critical reuse infrastructure, including a high-volume, tech-enabled washing facility. This facility will support higher throughput, lower costs, and more standardized operations — bringing reuse closer to cost parity with single-use packaging.
The Reuse Cities Initiative will focus on reusable packaging across multiple retail categories, initially building off of the NextGen Consortium’s in-market food service packaging reuse programming, and anchored on high-volume venues like stadiums, schools, possibly an airport, where we can deliver better unit economics and higher return rates.
Retailers play a key role.
Retailers and consumer brands from all sectors can play a big role in the Reuse Cities initiative. The initiative is setting up new regional reuse infrastructure that is initially set up to service the foodservice brands in the NextGen Consortium, but can expand to serve other packaging categories.
Leveraging the infrastructure (washing, reverse logistics, tracking systems, community education program) from the Reuse Cities Initiatives, brands and retailers will have an accessible entry point to reuse. Just as the beverage industry laid the foundation for current recycling systems, the foodservice sector is pioneering this next wave of at-scale reuse in retail and beyond.

Beyond the Bag Initiative Releases Its Largest Study to Date on Single-Use Bag Laws
July 15, 2025
The Consortium to Reinvent the Retail Bag unveils insights on bag policy aimed at eliminating single-use bag waste.
July 15, 2025, New York, NY — The Consortium to Reinvent the Retail Bag, managed by Closed Loop Partners’ Center for the Circular Economy, released a new in-depth analysis of single-use bag legislation in the U.S., setting a new standard in environmental policy research. The comprehensive policy white paper, “Legislation in Action: Measuring the Impact of U.S. Single-Use Bag Policies on Waste Reduction,” evaluates the efficacy and impact of various legislative mechanisms, including a comparison of bag fees and outright bans across diverse communities, revealing how different strategies influence bag waste reduction and consumer behavior.
Amidst increasing bag policy implementation across U.S. states, the white paper also reveals never-before-seen primary research into New Jersey’s pioneering legislation, the Get Past Plastic Act, which eliminated both single-use plastic and paper bags in grocery and big box stores. The rigorous analysis offers elected officials, regulators, community leaders and community stakeholders an objective summary of legislation’s impacts and potential unintended consequences on a community, enabling officials to effectively tailor legislation to their constituents and desired outcomes.
A key finding of the Consortium’s analysis on single-use bag legislation notes that while policy can be one of the most effective tools to reduce single-use bag waste, consumers must also be supported in adopting waste-free behavior. The Consortium’s 2023 in-market activations in Denver and Tucson, which tested consumer-facing bag reduction solutions in 375 stores across 160 different retailers, resulted in a 4.8% decrease in single-use bags across the two markets and an 11.7% reduction in Denver, where there was legislation. Overall, the city-wide activations resulted in up to 9.5 million single-use bags reduced annually across the two markets.
Building on these in-market findings and its in-depth policy analysis, the Consortium will launch a new consumer campaign this summer, encouraging consumers to bring their own reusable bags or choose not to take a single-use bag at all. Details of the campaign will be released in the next month.
“Policy is a major driver of the transition to the circular economy. While there is no single solution to reduce single-use bag waste, our rigorous analysis of legislation and in-depth understanding of consumer norm setting can provide communities with the tactical resources they need for a waste-free future,” said Kate Daly, Managing Partner and Head of the Center for the Circular Economy at Closed Loop Partners. “We look forward to sharing more insights on policy and the circular economy and activating in-market work alongside our partners to turn waste reduction practices into everyday habits.”
The Consortium to Reinvent the Retail Bag invites retailers, policymakers and community leaders to learn more about the efficacy of legislation through our detailed policy white paper. To access the full policy report, please visit closedlooppartners.com/beyond-the-bag/legislation/

For Reuse to Work, Language Matters
July 08, 2025
A quick guide to messaging for reuse programs and getting people to join in and participate.
When it comes to reuse, words matter. As we reinvent reusable packaging systems to thrive in today’s world, effective communication is as crucial as any operational consideration. Successful systems depend on brands and solution providers effectively guiding consumers to feel inspired and empowered to reuse—or at the very least, to foster awareness of and participation in new reusable programs.
Reuse comes with new habits: using and disposing is such an engrained part of our daily lives that asking people to return packaging takes significant cognitive effort. It involves asking time-starved consumers to digest new information and to act on it consistently throughout their day-to-day lives. To break through the noise of the 50-400 ads that bombard Americans every day, the first challenge of a new reuse program is to disrupt. Then, there are a few quick seconds to explain the new system and inspire consumers to take action, seeding a new habit that will be formed over time with consistent repetitions.
In 2024, Closed Loop Partners’ Center for the Circular Economy led an unprecedented collaboration in California that got an entire city reusing. The NextGen Consortium’s Petaluma Reusable Cup Project1 took on the challenge of making reusable cups a citywide norm. Working together with leading global brands, 30 local businesses and many local champions, we launched a campaign to inspire Petaluma to be part of the solution. The campaign reached 8.7 million media impressions, with 80% of people in the city aware of the program. In-store comms and signage played a disproportionate role in successfully driving awareness, understanding and returns.
In its three months, the initiative saw over 220,000 cups returned in the town of ~60,000 residents. Valuable learnings from over 1,000 consumer interviews and surveys during the Petaluma Reusable Cup Project taught us the best practices to strengthen reuse messaging.
Below are 5 keys strategies for brands and innovators to get their customers to reuse:
- Use consistent keywords and familiar phrases. People often don’t read instructions when approaching their trash bins, so they need consistent use of simple keywords to understand what they are supposed to do differently. A catchy slogan like ‘sip, return, repeat’ helps land the message. The use of clear fonts and bold text is also vital to cementing these new instructions.
- Lean on visual cues. Logos and symbols are important cues to quickly trigger the desired action. As it takes time for a logo to stand alone and carry its own meaning, symbols should be used along with words until they are recognized widely. It took time for the chasing arrows to become the universal sign for recycling, and it will take some time for reuse logos to get there too.
- Colors are an effective and accessible communication tool. Colors transcend words and logos. The right color selection can make consumers pause and look for more information. Colors can also convey that a product is more premium, influencing how shoppers subconsciously think about disposal. Matching the color of the bin to packaging can cue that items are meant to go there. In Petaluma, using color to signal that purple cups go in the purple bins helped business and consumers explain and understand the system quickly.
- Don’t overwhelm your customers with the problem of all packaging waste. Focus on the solution at hand and desired action, instead of the full scale of packaging waste to be solved for the planet, to help consumers engage meaningfully. And it’s best not to overpromise. Consumer communications should prioritize the part of the solution users need to participate in (i.e., in returnable packaging systems, to “return” packaging after use) rather than abstract or highly technical ecological benefits (i.e., that a reusable cup helps to avoid XX tons of CO2e).
- Gratitude and positivity go a long way. To show impact and build trust, corresponding signage and employee prompts can help drive home reuse as a new norm. Phrases like “thanks for being part of the solution” clue customers into how their action is contributing. Gratitude can also serve as positive reinforcement to accelerate a new social norm. Showcasing how many single-use cups have been prevented from going to landfill also helps reinforce the desired behavior and can be framed as a community achievement.
Show up consistently to deliver the message.
Packaging is the main vehicle for communication; each word and square inch counts to inspire and educate consumers on desired circular actions. Here’s how the Petaluma reusable cup was designed to disrupt, engage and inspire consumers to return:

When and how to use messaging on your packaging and collection bins:
| Messaging | Reasoning
|
| “Reusable cup” over “returnable cup | The consumer benefit is reuse – and the waste reduction for the community
|
| “Please return this cup” over “Please reuse this cup” | While the cup will be reused by a consumer, our goal is to establish a new return behavior
|
| “This cup will be washed and sanitized” over “this cup will be cleaned” | Consumers are reassured to know there is a step to remove debris AND a step to kill germs
|
| “Cup return bin” over “cup collection bin” | This trains consumers to think about a new return action rather than existing behaviors like trash collection
|
Language is just one part of the reuse culture; collaboration and consistency are key.
No matter how effective it may be, one sign, ad or piece of packaging design alone cannot spark a culture of reuse. It takes trusted brands, businesses, as well as public and community influencers working together to reshape the norm away from single-use packaging.
As brands refine language to make reuse compelling, being at the table with the right partners is critical to making reuse stick. As reuse moves from closed systems to city-wide programs, using words that resonate––and collaborating with partners across the value chain––will be a key driver to further scale.
Closed Loop Partners’ Composting Consortium Launches Grant Program with USCC and BPI to Scale the Recovery of Compostable Packaging and Food Scraps
May 06, 2025
The grant program for composters and communities comes at a critical time when support for infrastructure upgrades and community education is needed to encourage the recovery of certified compostable products that help divert food waste from landfill.
May 6, 2025, New York, NY — The Composting Consortium, managed by Closed Loop Partners’ Center for the Circular Economy, is launching a grant program in collaboration with the US Composting Council (USCC) and the Biodegradable Products Institute (BPI) to help composters and municipalities expand their ability to process certified compostable packaging and food scraps. Eligible U.S. compost manufacturers and municipalities are invited to apply for funding to support on-site improvements, public education and market development that allow for the inclusion of these materials.
The Consortium’s grants aim to support financing for crucial upgrades that enable the processing of certified compostable food packaging and food scraps, which reduces packaging and food waste in landfills and supports a circular economy for organics. Funding can be used by composters and municipalities in various ways, such as offsetting the costs of installing new equipment to address contamination from conventional plastics, conducting trials for the inclusion of compostable packaging, or updating signage, stickers and other marketing and outreach materials that clearly communicate the acceptance of certified compostable packaging to help improve participation and reduce contamination.
The grant program is launching at a critical time, as the U.S. composting industry is still in an early stage of accepting food scraps––with a majority of facilities only accepting yard trimmings––and consumers are increasingly seeking opportunities to divert food waste. Today, approximately 70% of the roughly 200 commercial compost facilities in the U.S. that process food waste also process limited formats of food-contact compostable packaging. Around 45% of curbside food scrap collection programs and 65% of drop-off collection programs allow certain formats of compostable packaging, with the understanding that accepting these materials helps divert more food waste from landfill, where it is a significant emitter of greenhouse gases.
“As the composting industry continues to grow, ensuring that compost manufacturers have the tools and incentives to successfully accept and process certified compostable packaging and food scraps is crucial,” said Frank Franciosi, Executive Director of the US Composting Council. “This funding will help strengthen the circular economy for organics, compostable packaging and our industry.”
“Composting plays a vital role in reducing organic waste in landfills and building healthy soils––but updates are needed to ensure that our composting system can meet the volumes and diversity of materials entering the organics stream today,” said Paula Luu, Senior Project Director at Closed Loop Partners’ Center for the Circular Economy and Composting Consortium lead. “These grants can provide composters and communities with the resources they need to scale their impact and support zero waste goals.”
“These new grants build on BPI’s micro-grant program launched last year, which promoted programs that already take compostable products, by providing larger sums that can move the needle by encouraging the development of new or expanded access to programs,” said Rhodes Yepsen, Executive Director of the Biodegradable Products Institute. “Partnering with the Composting Consortium, whether on grants, field testing, contamination studies or consumer testing, aligns with our core mission, and we are excited to continue our collaborative approach to building pathways that are good for business, for people and the planet.”
The grant program builds on the Composting Consortium’s ongoing work to strengthen composting infrastructure, validate best practices for processing compostable packaging, and advance policies that support the industry. By partnering with composters and municipalities, the Consortium, USCC and BPI seek to close the loop on compostable materials and ensure they, and the food nutrients they carry, are diverted from landfill and processed by composters.
Grant applications are now open, with a submission deadline of June 13th, 2025. All funded projects must be completed by March 1, 2026.

New Data Reveals High Quantities of Food-Grade Polypropylene in Recycling Facilities, Identifying Opportunities for Increased Material Recovery
March 25, 2025
Closed Loop Partners’ Center for the Circular Economy deployed Greyparrot’s AI-powered vision systems at four U.S. materials recovery facilities, revealing new data on the volumes of recycled food-grade PP––a material in growing demand.
March 25, 2025, New York, NY – Today, Closed Loop Partners publishes new data revealing high volumes of recycled food-grade polypropylene (PP) captured at materials recovery facilities (MRFs). The study, led by the Closed Loop Foundation and Closed Loop Partners’ Center for the Circular Economy, in collaboration with technology company Greyparrot and four U.S. MRFs, leveraged AI-powered vision systems to characterize the PP recycling stream with unprecedented detail. These results fill data gaps on the availability of food-grade PP, which can create new opportunities to return this material to foodservice packaging supply chains.
The findings are released amidst growing demand for recycled food-grade PP, driven by policy shifts––including recycled content mandates and Extended Producer Responsibility (EPR)––and commitments from brands to incorporate more recycled materials in their packaging. Despite increased market demand, there has been a significant lack of data on the available volumes of recycled food-grade PP in the recycling system. With no easy way to track, differentiate and separate food-grade and non-food-grade PP, these materials typically blend together at MRFs, making it challenging to amass the appropriate quantities of food-grade PP to meet growing market demand.
With funding from the NextGen Consortium and the Closed Loop Foundation, the Center for the Circular Economy teamed up with Greyparrot and four MRFs to reveal what was in the PP recycling stream, including the volume of food-grade and non-food-grade items, as well as color, format and other critical identifying features. Nearly 45 million individual PP and non-PP objects were characterized over the course of the study, revealing newfound granular details on the PP comprising the stream.
The study revealed 3 key findings:
1. Clear and white food-grade PP is abundant: On average, more than 75% of the PP captured in the study was white or clear, most of which was also presumed to be food grade. Furthermore, over 30% of clear PP packaging identified were beverage cups. This has important implications for meeting growing food-grade PP demand and how to retain more value in the system.
2. AI-enabled technologies can reliably quantify and classify recyclables with granularity, at scale: AI systems, such as the Greyparrot Analyzer, proved reliable in providing effective material characterization data at previously unavailable scales. This indicates the potential for AI to drive value to MRFs through increased intelligence and data granularity on material flows.
3. AI can help measure and track facility and equipment performance: Upgrades to optical sortation technology at MRFs had a notable impact on improved material sortation. This was progress that the AI technology was able to track and provide critical analytics on, indicating the potential for AI to offer enhanced performance evaluation data for MRF operators.
“The data captured demonstrates what is possible for the future of recycling and circular materials management, when powered by technology that can enhance transparency in the recycling system and increase high-quality material recovery,” said Kate Daly, Managing Partner and Head of the Center for the Circular Economy at Closed Loop Partners. “As we continue our work with many of the world’s largest retailers and foodservice brands, we look forward to identifying more opportunities to pull valuable food-grade materials back into foodservice packaging supply chains––a critical step toward recycled content goals and packaging circularity.”
“This work provides important data and transparency around the performance of AI technology and its capabilities within MRFs. We are proud to contribute critical data on the presence and quantity of food-grade objects within the PP stream,” said Gaspard Duthilleul, COO of Greyparrot. “In just three months, Greyparrot Analyzers characterized over 45 million PP and non-PP materials—a process that would take nearly four years manually, as manually characterizing just 1,000 pounds of material can take an entire day. This scale uncovers new opportunities for data collection at recycling facilities, serving as the foundation for increased recovery of valuable materials.”
While the characterization study focused on uncovering better data at one node of the PP recycling value chain, the results underscore that strong recycling data can enhance recovery opportunities and create new value up and down the recycling system.
These insights lay the groundwork for additional studies that can generate new, valuable recovery opportunities further downstream. Moving forward, Closed Loop Partners’ Center for the Circular Economy will continue to identify opportunities to leverage new data and innovations to advance material recovery with the recycling industry and global retail and foodservice brands.
This collaborative work aims to drive greater recovery of food-grade polypropylene––and other materials––and keep these valuable resources in circulation in local supply chains. To learn more and to visit closedlooppartners.com/center

Keeping Compost Clean: Tools to Help Reduce Contamination in the Food Waste Stream and Increase Compostable Packaging Recovery
March 17, 2025
This is part of a series of interviews with key players across the composting value chain, conducted by the Composting Consortium, a multi-year industry collaboration managed by Closed Loop Partners’ Center for the Circular Economy. In this series, we spotlight industry initiatives to advance a more robust, resilient composting system that can keep food-contact compostable packaging and food scraps in circulation, to reduce food waste and mitigate climate impact. This week, we are interviewing Eco-Products to learn more about CIRC, an important tool to reduce contamination at composting sites.
Eco-Products®, a Novolex® brand and certified B Corp, is a provider of foodservice packaging made from renewable, recycled and reusable materials. In 2023, the company launched CIRC (Controls Intended to Remove Contamination), an easy-to-use set of customizable tools and frameworks to help generators––such as restaurants and stadiums––packaging manufacturers, distributors, haulers and composters control and manage contamination from non-compostable products and get rid of contamination before it makes its way to the composter.
Composting Consortium: We know that contamination is a systemic challenge and one of the greatest barriers to the recovery of compostable packaging. As a brand who sells and manufactures these compostable materials, tell us how you’re combating the pervasive challenge of contamination in food waste streams.
Eco-Products: Contamination in compost streams is the defining challenge for composters, often leading to inefficiencies and increased costs. We’ve experienced this reality firsthand in Colorado, where Eco-Products is headquartered. Contamination from non-compostable materials has wreaked havoc on the local composting ecosystem in Colorado. We believe that food-contact compostable packaging—in addition to recyclable and reusable materials—has a key role to play in diverting food waste from landfill. We want to see compostable packaging succeed as a solution, but we know that contamination must first be solved to achieve that reality. We know this challenge isn’t exclusive to Colorado, and we knew we had to do something about it, so we developed a program called CIRC (Controls Intended to Remove Contamination).
Composting Consortium: How exactly does the CIRC program work and who is it for?
Eco-Products: Unlike third-party certifications, CIRC is a customizable tool that is designed to build trust, transparency and accountability between generators—such as restaurants, stadiums or event venues—packaging manufacturers, distributors, haulers and composters. The CIRC Toolkit offers a menu of recommended contamination controls spanning Procurement, Operations, Communication, and Composter & Hauler Engagement that we call “the scorecard.” Each section has a list of controls that are practical and useful for mitigating contamination in the compost stream. The program verifies that foodservice operators have taken key steps to avoid sending non-compostable items to composters, ensuring that everyone involved in the composting process is aware of their role in preventing contamination. With CIRC, composters can have greater confidence in the organics streams they receive.
Composting Consortium: Can you give us an example of how a stakeholder can use the tool?
Eco-Products: Yes! For example, a restaurant can reference the ‘Procurement’ section of the scorecard for a list of best practices and guidance when ordering and stocking certified compostable packaging. By following these order requirements, the restaurant can feel confident that the products they’re ordering have been approved by the certifier, the operator and the composter.
Composting Consortium: What makes CIRC different from other solutions?
Eco-Products: One of the standout features of the CIRC program is its open-source nature. This means that anyone, regardless of whether they are an Eco-Products customer, can access and benefit from the program’s resources.
For composters, the primary benefit of CIRC is the reduction in contamination, which leads to more efficient composting processes. With fewer non-compostable materials to sort out, composters can focus on their primary duty: producing high-quality compost.
For haulers and distributors, reducing contamination can lower the costs associated with handling and transporting contaminated loads.
For businesses and organizations committed to food waste reduction, adopting the CIRC program can contribute to a more sustainable waste management system. Restaurants, stadiums, and other venues that implement CIRC can enhance their reputation among environmentally conscious customers. Demonstrating a commitment to reducing waste and supporting composting efforts can attract and retain customers who value sustainability.
Composting Consortium: What advice would you give to brands, generators, haulers or composters who are struggling with contamination?
Eco-Products: Try using CIRC! To date, our program has been piloted at two locations: Knox College in Galesburg, Illinois and the University of Colorado, Boulder. In both instances, we’ve seen great results and dramatically reduced levels of contamination. We are calling on more stakeholders to utilize this free resource and are happy to support any organizations or businesses with the use and implementation of this tool.
Composting Consortium: What are your future plans for the CIRC program and how do you envision supporting the expansion of composting infrastructure?
Eco-Products: We plan to expand our CIRC program this year by creating supplemental resources, including a check list for assessing operational contamination risk factors. By helping reduce contamination issues through CIRC, we aim to help create a pathway for compostable packaging to succeed as a solution for food scrap recovery.
Composting Consortium: What inspired you to join the Composting Consortium as a Material Innovation Partner?
Eco-Products: When we learned that the Composting Consortium launched a Material Innovation Platform last year, we knew we had to get involved. The Composting Consortium’s groundbreaking research and in-market testing over the last three years has paved the way for dialogues in this industry that are helping to move the needle for compostable packaging. In particular, the Disintegration Study was a game-changer for the industry—offering data and proof points on how certified compostable materials break down in compost piles. We’re excited to continue our partnership with the Composting Consortium because we believe that this initiative is uniquely positioned to scale food waste composting infrastructure, help solve for contamination and drive positive, lasting change for the industry.
