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.”
This report is part of Closed Loop Partners’ broader work to support recycling and circular economy infrastructure in the U.S. across its platform. Closed Loop Partners’ innovation firm, the Center for the Circular Economy, has partnered with several leading recycling facilities across the country to test the recovery of packaging materials.

What Did It Take for Austin, Texas to Start Recycling Paper Cups?
October 01, 2025
To-go paper cups are ubiquitous, everyday items that we all interact with. They are also a highly visible representation of our disposable, take-make-waste culture. Every year, an estimated 250 billion cups are used globally—the majority of which end up in landfills after a single use.
Today, paper cups are still the most commonly used vessel for spontaneous coffee and beverage runs. Where possible, we must ensure the value embodied in paper cups—specifically the high-quality fiber—is recovered, rather than wasted in the landfill.
Since 2018, the NextGen Consortium, managed by the Closed Loop Partners Center for the Circular Economy, has worked to increase the circularity of foodservice packaging, with a focus on cups––from single-use fiber and plastic cups to reusable cups. The Consortium has worked with stakeholders across the paper cup recovery value chain—paper mills, materials recovery facilities (MRFs), brands, consumers and local communities, as well as industry groups including the Foodservice Packaging Institute (FPI)—to test cup recovery, and scale stronger infrastructure and end markets for paper cup recycling.
Scaling paper cup recovery is hinged on creating solutions that work for different locations. Each city and facility is distinct in their needs, opportunities and challenges, and solutions must be tailored to each context. End markets must exist to strengthen the business case for materials recovery for paper mills and MRFs.
With paper cups now included in Recycled Materials Association’s materials specifications list, momentum is accelerating for cup acceptance at different facilities across the U.S.
Circular Services, the largest private recycling company in the U.S., owns and operates the Austin, Texas, MRF which has been among the facilities that have moved the needle on cup acceptance in the U.S.
To learn more about why the Austin MRF made the decision to accept cups, and the work needed to further scale acceptance in more locations across the U.S., we went straight to the source.
Joaquin Mariel, Chief Commercial Officer at Circular Services, interviewed by Daniel Liswood, Senior Project Director of the NextGen Consortium at Closed Loop Partners’ Center for the Circular Economy:
Dan Liswood: To get us started, can you share more about Circular Services, and why paper cups are a material of interest to your company?
Joaquin Mariel: Circular Services is one of the largest privately held recycling and circular economy services providers in the United States. We are a commodities company––we don’t own landfills or manage waste. Our focus is on recovering materials like paper, plastic, glass and metal because we believe these are not waste, but valuable commodities that should be kept in circulation, not buried. Recovering and selling these materials is not only possible, it’s profitable.
The fiber in paper cups and other polycoated paper items is a valuable commodity. We’re always looking to expand the list of materials we can recover, and any opportunity to divert more from landfill is worth exploring.
DL: After many years of work to advance increased cup recovery across the U.S., we are very excited about the cup acceptance milestone in the City of Austin! Can you share more about what exactly is now accepted at Circular Services’ Austin MRF?
JM: Our MRF in Austin, TX is now accepting polycoated paper items—typically used as food and beverage containers. This includes paper cups (hot and cold), food and beverage cartons, paper plates and paper to-go containers. These items should be recycled like other containers: empty of food or liquid and with lids on.
Further, our partnership with the City of Austin is an additional motivator to expand the accepted materials list. Austin has focused on aggressive zero-waste objectives for several years, so we are mission-aligned. This helped streamline contract updates and community engagement efforts once we were ready to process polycoated paper.
DL: Before we dive into what made this possible, can you share more about why cups and cartons could not be accepted before?
JM: For a material to be accepted at our MRFs, we must have the capability to effectively sort it, either into its own stream or an existing commodity stream, and there must be reliable end-markets that purchase, process and reuse the material. If the material is a new commodity, there also has to be sufficient volume to justify the addition of a dedicated sortation system. In Austin, we did not have dedicated sortation to separate cups and cartons at our MRF and there hadn’t been consistent end markets for polycoated paper.
We’re fortunate that there is increasing focus on end market development––and thanks to generous grant support from the Foodservice Packaging Institute, the Carton Council of North America, and the NextGen Consortium, we’ve now installed the equipment needed to sort and bale these items for sale.
DL: How have broader conditions changed to support cup acceptance at your facility? What needs to be true for cup acceptance to continue growing?
JM: Several conditions have supported cup acceptance at our facility. Grants for sorting technology have enabled us to adapt our processes, and the development of more reliable end markets provides confidence that recovered cups have a sustainable outlet. Collaboration across the value chain has also been critical, ensuring all perspectives are considered in building a system that works.
For cup acceptance to continue growing, we’ll need to see continued investment in sorting capabilities, strong and stable end markets, and ongoing collaboration among stakeholders to align solutions across the system.
DL: Does accepting cups at the Austin facility change your perspective on cup recycling in other markets?
JM: Accepting cups at our Austin facility doesn’t necessarily change our perspective, but it does serve as a valuable proof point. It shows what conditions need to align—sufficient volume, the right infrastructure and strong end markets—for cup recycling to be successful.
Recycling is inherently regional, since material composition and market access vary widely. What we’re learning in Austin will help us identify where similar conditions exist in other markets—or highlight where gaps still need to be addressed. Any opportunity to divert more material from landfill is a win, and we’re always working to make more of those opportunities possible.
Closed Loop Partners Deploys $10 Million Loan to TemperPack, Advancing Circular Packaging Manufacturing and Strengthening End Markets for Recyclable Materials
September 30, 2025
This marks Closed Loop Catalytic Capital & Private Credit’s third loan to TemperPack, supporting the company with additional capital as it pursues broader expansion plans.
September 30, 2025, New York, NY –– Closed Loop Partners today announces a $10 million loan to TemperPack Technologies (“TemperPack”), a leader in sustainable, innovative packaging technology. The financing was deployed by Closed Loop Partners’ Catalytic Capital & Private Credit group and will support TemperPack’s continued growth in the sustainable packaging sector.
This financing marks Closed Loop Catalytic Capital & Private Credit’s third loan to TemperPack since 2018, reinforcing the group’s long-term commitment to supporting private companies that reduce waste and advance circular manufacturing. Deploying capital to innovative private companies such as TemperPack is an important component of Closed Loop Catalytic Capital & Private Credit’s strategy. The group is focused on providing flexible capital to support private companies, organizations and municipalities that have developed or are developing circular economy-focused projects or products, and are seeking more capital to drive net positive environmental and social outcomes.
Based in Richmond, Virginia, TemperPack develops innovative plant-based packaging and manufacturing technologies that help reduce waste and hard-to-recycle materials in supply chains. Its latest offering, WaveKraft, allows customers to simplify their operations and optimize packaging performance with an on-site, on-demand packaging manufacturing platform.

Over the past several years, TemperPack has demonstrated strong growth and financial stability. This, coupled with near-term plans to further innovate and explore different business models that require outside capital, positioned them well for a follow-on loan. As more packaging companies transition their focus to fiber-based packaging, Closed Loop Catalytic Capital & Private Credit believes TemperPack will benefit from the shift. This financing complements Closed Loop Catalytic Capital & Private Credit’s loans to other entities up and down the circular economy value chain, including materials recovery facilities (“MRFs”) and municipal residential recycling programs, to advance material circularity.
Proceeds of this financing will be used to support TemperPack’s research and development, manufacturing and distribution of more sustainable and easier-to-recycle fiber-based products that help reduce the reliance on harder-to-recycle plastics such as Expanded Polystyrene Foam (EPS). While the use of EPS as a packaging material has declined, it continues to be used in industries such as food and beverage and healthcare. With limited infrastructure that can properly recycle EPS in the U.S., the material typically ends up in landfills or incinerated. Solutions like TemperPack’s helps address this challenge.
“TemperPack is a prime example of the kind of company we seek to support—established, forward-thinking and focused on reducing environmental impact through scalable innovation,” said Jennifer Louie, Managing Director of Closed Loop Catalytic Capital & Private Credit at Closed Loop Partners. “Our continued investment in TemperPack aligns with our mission to build a circular economy, reduce waste and promote sustainable manufacturing, not just through recycling, but by reducing the need for hard-to-recycle materials in supply chains.”
“We’re thrilled to continue our partnership with Closed Loop Partners as TemperPack enters its next phase of growth,” said Peter Wells, CEO of TemperPack. “Closed Loop Partners’ experience in material circularity, and extensive network of partners, has made them a key partner for our company’s growth. With this loan, we look to further scale our capacity and impact, helping reduce waste across major industries––including life sciences, food & beverage, electronics and home goods––while catalyzing the development of new circular products.”
The financing from Closed Loop Catalytic Capital & Private Credit signals its readiness to deploy larger amounts of capital and partner with sophisticated co-investors, including major financial institutions. With this transaction, Closed Loop Catalytic Capital & Private Credit becomes TemperPack’s second-largest lender, demonstrating the group’s ability to help impact-driven companies scale from early-stage innovators to more mature businesses with shovel-ready capital expenditure projects that advance the circular economy.
Following this financing, Closed Loop Partners will continue to support TemperPack as it expands its processing capacity, improves existing facilities and pursues new product development. Closed Loop Catalytic Capital & Private Credit continues to catalyze capital into circular economy infrastructure and solutions that keep a range of valuable materials in circulation.

Behind SoCal’s Break-Up [With Single-Use Bags]
September 23, 2025
This summer, the Consortium to Reinvent the Retail Bag—a collaboration managed by Closed Loop Partners’ Center for the Circular Economy—launched the largest retail campaign of its kind in California with Target, CVS Health and The Kroger Co.
The Break Up With Single-Use Bags campaign deploys messages in stores and in communities across four southern California counties to remind people to bring their own reusable bag rather than relying on paper or plastic single-use bags.

Since its launch, our team has visited hundreds of stores across Southern California, meeting with our retail partners and store teams, and seeing how the campaign is coming to life.
From big retailers to neighborhood shops, we’ve heard the response: customers, retailers and communities welcome a little help in making changes that reduce waste and save money. Read about what we’ve learned so far!
Who is participating in the campaign?
Over the last few months, we worked with retailers big and small to bring this bag reduction and reuse campaign into over 1,300 stores across the Inland Empire, Orange County and San Diego County. Teams were out in the field for weeks, dropping off free signage and talking with store staff. We also connected more than 300 stakeholders, from city governments to community nonprofits, to strengthen a local effort that will reach millions of people.
What does the campaign look like on the ground?
The campaign isn’t limited to just stores. Messaging appears at home, in the community, in the parking lot, and at checkout. In stores, it’s about giving people simple reminders and the confidence to choose what works best for them, bringing a bag or skipping one altogether. Those little nudges add up, turning good intentions into everyday habits. We’ve found that to be true in Beyond the Bag’s past in-market tests in Denver and Tucson, which resulted in up to 9.5 million fewer bags used across those two test markets.

What are we hearing so far?
Customers and employees appreciate the support, as California prepares to phase out plastic bags effective January 1, 2026. Many pointed out that the “reusable” bags currently provided by stores don’t always end up being reused. At the same time, customers don’t want to return to the single-use bags of the past and are apprehensive about relying on paper bags, which they consider less durable.
“They’re going away completely? I really don’t like paper bags so I’ll probably start just bringing my own, then.” – Customer in Santee, CA (San Diego County)

But shoppers have built routines around their bag use, and breaking those habits takes support. What we are hearing customers ask for are practical options and simple reminders that make it easier to build new habits that move beyond flawed single-use bags. Retailers value the campaign as a way to mitigate challenges with the state’s transition to paper bags while helping customers make choices that work better for them.
“I recently stopped taking plastic bags because I found myself never reusing them, but it can be hard to remember your bag all the time. Signs like these are helpful, I’d love to see them everywhere.” – Customer in Irvine, CA (Orange County)
Why a break-up?
We knew from the start that if we were going to ask customers to change a habit, the message needed to stand out, and ideally, make them smile. The break-up theme grew out of consumer testing in Southern California and landed on the right balance of lighthearted, relatable, memorable and actionable.
It also gives customers choice, whether that means bringing a trusted reusable or skipping a bag altogether, while helping them move beyond the flawed and costly single-use options of the past. The campaign aims to support new habits in a way that feels less like a lecture and more like a wink.
What’s next?
The good news is that there is no definitive end to the campaign––it’s not meant to be a short-term fix. Rather, it is meant to be a tool toward a long-term shift, because we know that sustained change and impact happens over time.
Retailers can join anytime and roll out signage and messaging at their own pace, using free open-source assets, social media content, and step-by-step implementation guides. Smaller stores can even receive pre-printed signage at no cost.
By participating alongside nearly 1,300 other stores, retailers benefit from the higher impact of joint action, and reduce the risks of starting a new program alone. By proactively supporting their customers through this shift, retailers can also mitigate the operational and cost impacts of the state’s transition to paper bags.
The work doesn’t stop here. We’re collecting and analyzing on-the-ground data to understand the full impact of these interventions. The more we learn, the more effective we can be, not just in California, but anywhere retailers and communities want to reduce single-use waste.
Closed Loop Partners Deploys New $10 Million Loan to Canadian Molecular Recycling Company GreenMantra Technologies to Advance Plastics Circularity in North America
September 17, 2025
New York NY, September 17, 2025 — Today, Closed Loop Partners announces the deployment of an over $10 million loan from its Closed Loop Infrastructure Group to Canada-based GreenMantra Technologies, a molecular recycling company at the forefront of creating specialty waxes and polymer additives from recycled polyethylene (PE) and polypropylene (PP). This is the Infrastructure Group’s third loan to GreenMantra over the course of the last decade. This latest investment will be used to finance equipment to increase material processing at their existing Brantford, Ontario facility.
Founded 15 years ago, GreenMantra has commercialized a proven and scalable technology to utilize plastics that are typically hard to recycle. Using a patented process, the company molecularly modifies plastic waste into new, high-quality materials that can be used in everyday industries like roofing and road paving to drive greater value and sustainability in the finished product. GreenMantra offers a depolymerization process that is more energy efficient than other similar technologies, converting the waste plastics into specialty performance additives. Technologies like this are essential for tackling the huge variety and amount of plastic waste generated. Molecular recycling, alongside material reduction, reuse and mechanical recycling, is needed to move the needle on plastics currently recycled globally.
“Optimizing plastics recovery in North America requires diversified solutions––including mechanical and molecular recycling technologies in the region. These solutions must work collaboratively and meet the standards needed for economic viability, and environmental and human health impact,” says Jennifer Louie, Managing Director of the Closed Loop Infrastructure Group at Closed Loop Partners. “GreenMantra demonstrates a resilient business model, a technically proven process and a clear path to scale. We look forward to continuously supporting the company as they further their mission to valorize plastic waste otherwise destined for landfills.”
This round of financing takes place amidst growing supply chain volatilities and an increasingly urgent need to secure additional sources of valuable materials that do not rely on resource extraction or landfills. The capital is deployed from the Closed Loop Infrastructure Group’s Circular Plastics investment strategy, backed by Dow, LyondellBasell, NOVA Chemicals, Sealed Air, SK geo centric Co., Chevron Phillips Chemical, Charter Next Generation and Sumitomo Mitsui Banking Corporation. The Circular Plastics Strategy actively seeks to invest in sustainable technologies, organizations and projects that advance the recovery and recycling of plastics in the U.S. and Canada, helping to meet the growing demand for solutions that keep high-quality and valuable materials in circulation.
Financing from the Closed Loop Infrastructure Group, a team with extensive experience in material circularity for plastics and beyond, is expected to increase GreenMantra’s output of specialty products by approximately 50%, significantly enhancing its ability to do more for communities, its customers, and plastic waste diversion from landfills.
“This financing marks a significant acceleration in our work to scale solutions that help ensure hard-to-recycle materials do more for our planet,” says Domenic Di Mondo, Chief Executive Officer at GreenMantra Technologies. “With the support of Closed Loop Partners and other investors, we’re now expanding commercial capacity for our products to meet growing demand––transforming even more recycled plastics into high-performing materials, and keeping valuable resources in circulation.”
Following this investment round, GreenMantra will continue to pursue near-term geographic expansion opportunities, scaling reliable product solutions and advancing the worldwide transition to a more resilient circular economy. The Closed Loop Infrastructure Group continues to catalyze capital into circular economy infrastructure and solutions that keep a range of valuable materials in circulation.

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.

How Smart, Scalable Sensors Are Reducing Waste in the Built Environment
August 14, 2025
Why We Invested in LAIIER, a Denver-based startup pioneering printed sensor technology for leak detection in buildings and data centers.
At Closed Loop Partners, we invest in companies that are not only solving urgent environmental challenges but also building resilience into the systems we rely on every day. Our investment in LAIIER—a Denver-based startup pioneering printed sensor technology for leak detection—is a reflection of this mission. LAIIER is tackling a critical and costly issue: liquid leaks in commercial and industrial buildings and infrastructure. By detecting water and other liquid leaks, they are enabling a future where our built environment is smarter, more sustainable, and more resilient to climate-related risks.
The Problem: Hidden Leaks, Escalating Risks
Leaks in buildings and infrastructure like wind turbines are a silent threat. They cause billions in damage annually, disrupt operations and contribute to the waste of finite water resources. In data centers, commercial real estate and industrial facilities, even minor leaks can lead to catastrophic failures. Traditional detection methods are slow and reactive, with average response times exceeding 80 hours. This delay not only drives up insurance claims and repair costs but also increases vulnerability to infrastructure stress, reducing the life of critical assets. The more rapidly these assets must be sunset, the more we need to rely on new materials to replace them––an increasing risk as global supply chains increase in volatility and material availability is less consistent.
LAIIER’s technology offers a proactive defense—detecting leaks before they become disasters and enabling buildings to respond faster and smarter.
The Solution: Smart Sensors for a Resilient, Less Wasteful Future
LAIIER’s innovation lies in its Severn WLD™ system—a printed, adhesive sensor that can detect as little as two drops of liquid. These ultra-thin, flexible sensors can be installed in hard-to-reach areas and integrated directly into building materials, including roofing systems. This is especially critical for data centers and other high-value infrastructure, where downtime from water damage can cost millions.
The sensors are paired with LAIIER Cloud™, a real-time monitoring platform that provides analytics, remote configuration and alerts. This combination enables rapid response to leaks, reducing the risk of structural damage, mold and system failures. It also supports long-term resilience planning by generating data that can inform predictive maintenance and infrastructure upgrades.
LAIIER’s impact extends beyond resilience. Their technology is a powerful enabler of the circular economy. By catching leaks early, LAIIER prevents damage to walls, floors and ceilings––materials that would otherwise end up in landfills. This approach reduces both water and material waste, all while helping customers lower their insurance premiums and utility costs––creating a compelling value proposition that’s both environmental and economic.
The Applications: Where Smart Sensors Are Most Needed Today
One of the most exciting applications of LAIIER’s technology is in integrated roofing systems. Through a strategic partnership with Carlisle Construction Materials––who also participated in this funding round––LAIIER is embedding sensors into roofing membranes. This creates “smart roofs” that can detect and localize leaks in real time, providing a critical layer of protection for buildings vulnerable to heavy rainfall.
Data centers also benefit significantly from partnerships with LAIIER. As we build more, faster to meet our growing demand for AI, increasingly hyperscalers are relying on water-based cooling technologies. This means leaks can come from the inside just as easily as from outside sources––and when water intrusion compromises sensitive equipment, it can lead to cascading failures.
Why Now?
Rising insurance costs, stricter building codes and increasing costs from damaged equipment and downtime are driving demand for proactive leak detection. LAIIER’s technology addresses all of these challenges––helping customers reduce risk, save resources and build smarter, more adaptive infrastructure.
We invested in LAIIER because we believe in their mission, their team and their technology. Co-Founders Matt Johnson and Bibi Nelson bring over a decade of experience in printed electronics and have built a culture of thoughtful, impact-driven innovation. With a differentiated product, a growing customer base and strong strategic partners in insurance, roofing and elsewhere, LAIIER is poised to become a category-defining company in smart infrastructure. We’re proud to support them as they help build a more resilient, circular and sustainable future.

Closed Loop Partners Advances Major Progress for the Circular Economy, With Portfolio Companies Keeping Over $5 Billion of Materials and Products in Circulation Through Local and Regional Investments and Infrastructure Builds
August 12, 2025
The circular economy-focused firm releases 2024 impact report, detailing significant environmental and economic outcomes of its investments, initiatives and infrastructure builds.
August 12, 2025, New York, NY – Closed Loop Partners, a firm at the forefront of building the circular economy, today announces a notable contribution to the transition to the circular economy in its 2024 impact report. As of year-end 2024, the firm has kept nearly 16 billion pounds of materials in circulation and avoided over 25 million metric tons of greenhouse gas emissions, driven by over 90 investments in the circular economy across five continents, 10 countries and 29 U.S. states. As a result of over a decade of work, the firm’s portfolio companies have kept over $5 billion worth of valuable materials and products in circulation to date,1
The firm’s report is released amidst a confluence of shifts in the global economy, increasingly volatile international supply chains, growing support for domestic manufacturing, and only 27 years of median landfill capacity remaining in the U.S.––and less in population centers. Key market drivers have brought the circular economy to the centerpiece for future growth, as capital deployment toward solutions that increase material security and supply chain resilience accelerate. By 2030, it is estimated that the circular economy has the potential to unlock $4.5 trillion in economic value.
Recapping over a decade of transformative progress, Closed Loop Partners’ report spotlights several important regions in the U.S. where the firm has already reached marked density and scale of circular solutions––through investments, in-market activations and infrastructure builds. This includes an electronics recovery corridor in the Northeast, an expansive recycling and manufacturing ecosystem in the Midwest, unprecedented citywide reuse initiatives in cities across the Western U.S., novel circular materials hubs across the Southwest and the largest private recycling and organics processor in the U.S. Closed Loop Partners and its ecosystem of partners have made strides toward a circular economy powered by local communities and supply chains––and positioned for global reach and connection.
“Over 10 years ago, the circular economy was an emerging concept. Today, it is a proven global economic accelerator, replacing the hidden costs of landfilling resources, and unlocking new opportunities for economic growth by recovering materials that are increasing in demand,” said Ron Gonen, Founder & CEO of Closed Loop Partners. “We’ve built a platform focused on resource efficiency through market dynamics, delivering long-term value for our investors, businesses, communities and the planet.”
Closed Loop Partners was founded over a decade ago with backing from a number of Fortune 500 corporations, top financial institutions and family offices, and partnerships with leading industry experts and cutting-edge innovators. Given the scale of change required to achieve circularity, the firm’s approach has been grounded in collaboration and on-the-ground work, and accelerated by multiple solutions working alongside each other. The firm has achieved success by developing local circular systems that can be scaled nationally and replicated across the globe.
Today, Closed Loop Partners operates three distinct businesses––Closed Loop Capital Management, an investment group managing private equity, venture capital, and catalytic capital & private credit strategies; the Center for the Circular Economy, an innovation center that works with the world’s most influential organizations to solve pressing material challenges; and Closed Loop Builders, an operating group that incubates, builds and scales circular economy infrastructure, including the largest privately held recycling and organics processing company in the U.S.
Across its platform, Closed Loop Partners has contributed to a structural shift in how industries approach production, consumption and waste. In just a decade, the firm, together with its partners, has achieved several milestones, including:
- 90+ investments in solutions ranging from synthetic biology and regional recycling to advanced material recovery technologies through venture capital, private equity, and catalytic capital & private credit strategies;
- Pioneering reuse initiatives through the Center for the Circular Economy, including the first citywide reuse initiative in the U.S.; and
- 27 facilities and 3 billion pounds of material processed through Circular Services.
As Closed Loop Partners reaches a key point of $5 billion worth of valuable materials and products kept in circulation by portfolio companies since the firm’s inception, the company reaffirms its commitment to building resilient, circular systems that drive sustainable growth. In the coming decade, the firm looks to continue growth across its platform, expanding its investments in the circular economy, partnerships with corporates and leading institutions, and development of circular economy infrastructure across the U.S.
“As we enter the next decade, the intersection of economic opportunity and environmental resilience has never been more critical,” said Ron Gonen, Founder & CEO of Closed Loop Partners. “We are doubling down on our mission to accelerate the transition to a circular economy—one that is profitable, sustainable and built to last.”
1 This represents the market value of materials or products at the point in the value chain where they would have been lost to the linear economy, had a circular business not intervened. It does not include the numerous other ways that the circular economy adds value to the global economy, including jobs, wages, tax revenue and enabling associated businesses.
