NEW YORK, Aug. 7, 2024 — Today, the Composting Consortium, a collaboration managed by the Center for the Circular Economy at Closed Loop Partners, released a new blueprint to guide municipal leaders in zero waste, solid waste and sustainability in establishing and scaling composting infrastructure and organics management programs across the country. How Organics Diversion Can Help Achieve Zero Waste Goals: A Blueprint for Action, co-authored with Eco-Cycle, based in Boulder, Colorado, is an essential guide for municipalities seeking to develop food scraps collection programs and to work with composters to meet zero waste and climate goals. Alongside the release of the blueprint, the Consortium invites U.S. municipalities and composters to join two newly launched platforms that support municipalities and composters in scaling organics infrastructure.

Today, food waste in landfills is a major source of methane, a potent greenhouse gas that significantly contributes to climate change. Diverting food scraps and yard waste through municipal organics programs reduces methane emissions and provides environmental benefits such as improved soil health, water conservation, carbon sequestration, and support for local economies and ecosystems. To support this diversion, the U.S. composting industry is in an early stage of transformation. More composters are looking to accept and process more food waste; approximately 70% of composters who process food also accept and process some format of food-contact compostable packaging, with the understanding that accepting these materials helps bring in more food waste to their facilities. However, only 10% of U.S. households have access to organics recycling through drop-off and curbside organics collection programs, and only 4% of wasted food is sent to composters today.

“Since its launch in 2021, the Composting Consortium has been focused on moving the needle to change that statistic,” said Kate Daly, Managing Director and Head of the Center for the Circular Economy at Closed Loop Partners. “By creating this blueprint, we aim to equip municipal leaders with a basic ‘how-to’ manual to launch or scale successful organics programs that contribute to a zero-waste future, clean organics streams and a thriving composting industry.”

The blueprint, How Organics Diversion Can Help Achieve Zero Waste Goals, offers a clear and actionable framework, including:

• Policy and Program Expansion for Diverting Food Waste: This section does a deep dive into effective strategies for policy development. It explores methods to incentivize resident and business participation, while outlining pathways to maximize food waste diversion from landfills.
• Setting Up Programs and Infrastructure: This section provides a clear roadmap for establishing new organics programs. It details best practices for collection methods, explores various processing options (composting facilities, anaerobic digestion), and offers guidance on navigating the critical process of contracting with composters.
• Communication with Program Participants: Recognizing the importance of resident and business engagement, this section provides a comprehensive communications toolkit. It outlines strategies for educating participants on proper sorting techniques, maximizing program participation and fostering long-term program success.

To thoughtfully scale organics management, key stakeholders must collaborate. This helps ensure that composting programs and infrastructure are developed to meet the diverse needs of stakeholders across the organics value chain––from composters, to cities, residents, businesses and more. Alongside the release of the blueprint, the Composting Consortium is launching two new platforms to engage directly with municipalities and composters across the country to support the scale-up of robust composting infrastructure.

The Composting Consortium’s new Composter Innovator Program aims to bring composters across the U.S. to the table to play an active role in shaping the future of the composting industry on topics like contamination, policy and funding food waste composting infrastructure. The group will take on important questions, including identifying the cost of processing compostable packaging and offering recommendations on how to allocate Extended Producer Responsibility funds to support composting infrastructure development. The Consortium invites composters across the U.S. to sign up for the program and be involved in the growth of composting infrastructure across the U.S.

The Consortium is also launching its Municipal Partner Platform, a free-to-access platform for city officials focused on sustainability, zero waste and waste management. The platform connects officials with leaders nationwide to share and discuss best practices in starting and expanding organics collection and infrastructure programs. Municipalities of all sizes and stages of development are invited to reach out to the Composting Consortium to explore ways the network can help them achieve their goals of diverting food waste from landfills.

NEW YORK, April 16, 2024 /PRNewswire/ — Today, the Composting Consortium, an industry collaboration led by the Center for the Circular Economy at Closed Loop Partners, released a groundbreaking report that fills a critical data gap for the U.S. composting industry: how well does certified, food-contact compostable packaging actually break down in real-world composting facilities? The report, Breaking It Down: The Realities of Compostable Packaging Disintegration in Composting Systems, shares findings from an 18-month study––the largest known field test of certified, food-contact compostable packaging conducted in North America––revealing the realities of compostable plastic and fiber disintegration in diverse in-field composting conditions.

In total, the study tested over 23,000 units of certified food-contact compostable packaging within large-scale industrial composting environments. This encompassed 31 types of fiber packaging & products and compostable plastic packaging & products––such as PLA and PHA––across 10 diverse composting facilities across the U.S.

The data is released at a critical time, as compostable packaging grows as an alternative to conventional plastics amidst an urgent waste crisis. Roughly one-third of the world’s food is wasted each year––a loss estimated at $230 billion. Nearly 60% of the uncontrolled methane emissions from municipal landfills are caused by discarded food, highlighting its significant impact on the environment. To address the urgent food waste and climate challenge, demand for organics circularity is rising, and with it, the volume of food-contact compostable packaging––a market poised to grow 16% annually in the U.S. until 2032, 4x faster than traditional plastic packaging. Today, the U.S. composting industry is in an early stage of transformation to accept and process more food waste; approximately 70% of the composters who process food also accept and process some format of food-contact compostable packaging, with the understanding that accepting these materials helps bring in more food waste to their facilities.

For compostable packaging to reach its full potential as a circular packaging solution, disintegration at end-of-life is critical, in tandem with consistent labeling and design that differentiates compostable and non-compostable packaging further upstream, as well as policies that incentivize robust composting infrastructure to process these materials. In this new study, the Composting Consortium focuses on how compostable packaging breaks down. Previously, scant information was publicly available on the disintegration of compostable packaging, particularly on the compost environments in which they disintegrate.

This groundbreaking study found that overall, compostable packaging breaks down successfully at composting facilities that meet reasonable operational parameters (e.g., compost pile temperatures, moisture, oxygen, pH, etc., defined in The Composting Handbook). While the Consortium’s study did not assess disintegration with the intention to “pass” or “fail” any specific compostable packaging or product, notably, the average compostable plastic and fiber packaging in-field performance in this study met disintegration thresholds used by industry groups:

• Compostable plastic packaging and products broke down successfully across five composting methods, and all 10 facilities’ varying processing timeframes and operating conditions, achieving 98% disintegration on average by surface area, which exceeds industry thresholds to achieve a 90% or higher disintegration.
• Compostable fiber packaging and products achieved 83% disintegration on average by surface area, meeting industry thresholds to achieve an 80% or higher disintegration. Findings showed that certain operating conditions, like turning, agitation and consistent moisture levels above 50%, support increased disintegration of fiber packaging and products.

The findings point to the viability of certified food-contact compostable packaging as an alternative packaging solution to single-use conventional plastic packaging. It also highlights the importance of ensuring that these materials align with available recovery infrastructure, and the importance of expanding robust recovery pathways to divert compostable packaging, and the food scraps they carry, from landfill––that is at the core of the Composting Consortium’s mission.

The Composting Consortium, in collaboration with its brand and industry partners, the US Composting Council, the Compost Research and Education Foundation and other groups, will leverage these findings to help inform policymaking around compostable packaging, update best management practices for composting facilities and shape a field test standard for evaluating compostable packaging disintegration at composting facilities. Data from this study will be donated to the Compostable Field Testing Program (CFTP), which will later launch an open-source database on the disintegration of compostable packaging. Additionally, ASTM International is currently developing an in-field test method for assessing disintegration of compostable items at composting facilities, and the data from this study will be used to inform the draft field testing method. As the Consortium moves into its next phase of work, the results of this study will shape its engagement and education efforts with composters, municipalities, regulators, brands and packaging manufacturers.

“Field testing for disintegration has been ongoing for three decades, and the Composting Consortium’s work across the value chain has significantly advanced insights for the industry,” says Diane Hazard, Executive Director of the Compost Research and Education Foundation. “The collaborative approach and open-source data from this project both advances field testing methods and equips compost manufacturers and brands with the knowledge to better understand the variability of disintegration across different systems, all major steps towards successfully processing compostable packaging.”

“Brands and manufacturers must prioritize material selection and design and labeling for compostable packaging to achieve optimal performance in composting environments, which can then incentivize composters to accept food-contact compostable packaging materials at their facilities,” says Frank Franciosi, Executive Director of the US Composting Council, an industry partner of the Composting Consortium. “As feedstock for composters becomes diversified and more complex, it’s important for all entities within the supply chain to support consumer education on source separation of organics and reevaluate best management practices to support those composters who choose to accept compostable packaging, and this study is another tool for our industry to be able to start that process.”

“Alongside design and reduction as well as reuse and recycling, composting is an important solution for waste mitigation. Through this research, the Composting Consortium sheds light on what is needed for compostable packaging to have the greatest positive impact. Informed by this robust data, we can together ensure the responsible growth of compostable packaging and composting infrastructure, and drive toward circular outcomes, including increased diversion of food scraps and compostable packaging from landfills,” says Kate Daly, Managing Director and Head of the Center for the Circular Economy at Closed Loop Partners.

The study brought together the Consortium’s corporate brand partners, including PepsiCo, the NextGen Consortium, Colgate-Palmolive, Community Impact at Danaher, Eastman, The Kraft Heinz Company, Mars, Incorporated and Target Corporation; technical partners including the US Composting Council, Resource Recycling Systems (RRS), the Compostable Field Testing Program (CFTP) and the Biodegradable Products Institute (BPI); and a cohort of compost partners including Atlas Organics, Napa Recycling & Waste Services, Specialized Environmental Technologies, Windham Solid Waste Management, Black Earth Compost, Ag Choice Organics Recycling, Happy Trash Can Compost, Veteran Compost and Dayton Foodbank. Advisory partners include 5 Gyres, Foodservice Packaging Institute (FPI), ReFED, the Compost Research and Education Foundation (CREF), the Sustainable Packaging Coalition (SPC), Compost Manufacturing Alliance (CMA), Eco-Cycle, University College London (UCL), Western Michigan University (WMU), University of Wisconsin-Stevens Point and World Wildlife Fund (WWF).

February 28, 2024, New York, NY — Today, the Composting Consortium, an industry collaboration led by the Center for the Circular Economy at Closed Loop Partners, released an unprecedented report on compost contamination, Don’t Spoil the Soil: The Challenge of Contamination at Composting Sites. The report reveals first-of-its-kind data on the amount of contamination at U.S. composting facilities, and the significant cost to manage it. Working with composters across the U.S., the Consortium’s in-field study quantifies contamination rates in feedstock and finished compost, highlighting a need for policy, innovation and packaging design to help composters improve contamination mitigation and strengthen organics recovery processes.

The report is released at a critical time for the composting industry, as pressure increases around the growing food waste crisis in the U.S. Today, nearly 40% of food is wasted and sent to landfill in the U.S.––at a loss of $430 billion––and only about 4% of all post-consumer food waste generated by Americans is sent to composters. Organics collection and infrastructure is one key solution to the crisis. To meet growing demand, the U.S. composting industry is shifting. While most composting facilities in the U.S. still only process yard trimmings, curbside organics collection has surged by 49% since 2021. Composter feedstock acceptance policies are also slowly shifting to match demand, with approximately 145 full-scale compost facilities in the U.S. now accepting food waste and some forms of food-contact compostable packaging—that packaging can be a key vessel for diverting food waste to compost, if recovered at composting facilities.

There is eagerness among compost manufacturers to be a part of the food waste solution, but concerns about contamination risks in the organics stream continue to be the one of biggest barriers to greater acceptance of food waste and food-contact compostable packaging. Concerns are increasing amidst the growing volume of compostable packaging in the U.S., largely due to look-alike, non-compostable packaging inadvertently entering the composting stream due to unclear labeling and confusion among consumers. This creates operational and financial challenges for haulers and composters, hindering further acceptance of food waste across the country.

Before the Composting Consortium released this report, there was little to no publicly available data on the amount and types of contamination in feedstock or finished compost products, or the time and money spent by composters to manage contamination at their facilities. To support the composting industry in its transition to accept food waste and food-contact compostable packaging, the Composting Consortium set out to address this data gap by conducting a first-of-its-kind study with 10 leading composters of varying sizes across the continental U.S., capturing a geographically and operationally diverse dataset on contamination volumes and decontamination practices.

The study measures and characterizes contamination across different points of the composters’ processes––and analyzes the financial cost to composters to handle contamination. The study examines five commonly held assumptions about contamination and compostable packaging, and breaks down in-field realities in a data-backed and easy-to-follow format. Key findings include:

• Conventional plastic is the most common contaminant received by composters, making up an average of 85% of the contamination that composters receive, by volume;
• Despite diligent efforts to combat contamination, conventional plastic can persist in the finished compost; 4 out of 10 composters in the study had trace amounts of conventional flexible plastic in their finished compost;
• Contamination has a significant impact on the bottom line; on average, 21% of composter operating costs are spent on contamination removal;
• Most composters had contamination, irrespective of whether or not they accept compostable packaging; several factors contribute to the levels of contamination that a facility receives;
• Eight out of nine composters who accept compostable products in the study had no detectable amounts of compostable packaging in their finished compost.

The data confirms the pervasiveness of plastic contamination, and the need to further mitigate this challenge, both upstream and downstream in the composting value chain. It also highlights that more consistent and standardized compostable packaging design and labeling is needed to ensure that certified, food-contact packaging is properly sorted and recovered at end of life. In the same vein, non-compostable packaging should be distinct in its design and labeling to reduce the risk of conventional plastic packaging making its way into the organics stream. Composters must be supported and incentivized to accept food and certified food-contact compostable packaging, to ensure these materials drive value and circular outcomes to the composting industry.

“Addressing contamination is critical to paving the way for broader organics recovery as a key solution to the food waste crisis in the U.S.,” says Kate Daly, Managing Director of the Center for the Circular Economy at Closed Loop Partners. “The Composting Consortium’s findings shed light on the significant opportunities––and challenging realities––of composting in the U.S. today. This study lays the groundwork for future research and investment to scale end-of-life solutions for food and food-contact compostable packaging to drive circular outcomes.”

This study is an important snapshot of a pervasive challenge that affects the compost industry. This work represents the Composting Consortium’s continued efforts to break siloes and bring together the key stakeholders––upstream, midstream and downstream––to remove barriers and advance a circular economy for organics and compostable packaging. Addressing contamination requires enhancing transparency, intensifying educational efforts and championing innovation. Additional research and collaboration across the entire composting and compostable packaging ecosystem can help pave the way for a circular future, turning food waste into a valuable resource and relieving composters from the burden of contamination.

About the Center for the Circular Economy at Closed Loop Partners

The Center for the Circular Economy (‘the Center’) is the innovation arm of Closed Loop Partners, a leading circular economy-focused investment firm in the U.S. The Center executes research and analytics, unites organizations to tackle complex material challenges and implement systemic change that advances the circular economy. The Center for the Circular Economy’s expertise spans circularity across the full lifecycle of materials, connecting upstream innovation to downstream recovery infrastructure and end markets.

Roughly one-third of the world’s food is wasted each year––a loss estimated at $230 billion. Nearly 60% of the uncontrolled methane emissions from municipal landfills are caused by discarded food, highlighting its significant impact on the environment. To address the urgent food waste and climate challenge, demand for organics circularity is rising, and with it, the volume of food-contact compostable packaging––a market poised to grow 16% annually in the U.S. until 2032, 4x faster than traditional plastic packaging.

Certified, food-contact compostable packaging can enable the diversion of food waste from landfill and support a circular economy. If food packaging filled with food scraps is properly recovered and sent to composting facilities, then this food wouldn’t end up emitting greenhouse gases in landfills. The food and packaging would also be converted into nutrient-rich compost. But if certified compostable packaging is not appropriately collected and processed into compost after it’s used, more waste is created.

We often hear that there is a lack of recovery infrastructure for compostable materials. The reality is, U.S. composting infrastructure is in the middle of transitioning from processing just yard waste to accepting more types of inputs, including post-consumer food waste and food-contact compostable packaging. Today, 70% of the 200 full-scale composting facilities that process food waste already accept and process some forms of compostable packaging. Plus, 15 million Americans have access to organics collection, a dramatic 49% increase in access since BioCycle’s last survey in 2021.

For food-contact compostable packaging to be successful in the market today, labeling and design need to be aligned so that consumers throw packaging in the right bin, and composters can easily process these materials. Yet, data shows that some labels confuse consumers, who mistake packaging as compostable when it’s not, or misunderstand where to dispose of that packaging at the end of its use.  

Without policies that drive clear, standardized labels and instructions on where compostable packaging needs to go after it’s used, a lot of it ends up in landfills or contaminating recycling streams. Conversely, non-compostable look-alike products and packaging can make their way to compost facilities where they end up contaminating the soil. These look-alikes are the primary contamination challenge in the organics stream.

To address this challenge, the Composting Consortium, led by the Center for the Circular Economy at Closed Loop Partners, and the Biodegradable Products Institute (BPI) embarked on a joint study to test different packaging label and design approaches, and how these inform consumers’ assumptions on what to do with compostable packaging after it’s been used. The findings can inform policies that better support labeling practices and standards for both compostable and non-compostable packaging. In the U.S. today, five states have compostable packaging labeling laws, including Washington, California, Colorado, Minnesota and Maryland. Other states, like Virginia and New Jersey, recently introduced laws that would establish recycling labeling requirements.

Until this study, this information on American consumers had not been publicly available.  The Composting Consortium and BPI released the findings in a first-of-its-kind industry report. Here’s a snapshot of what the data reveals:

• Nearly 1/3 of respondents say they would place compostable packaging in the recycling bin

Compostable packaging is not designed to be recycled at a material recovery facility (MRF) and can contaminate the recycling stream if intermixed with fossil fuel-based plastics. Compostable packaging that mistakenly ends up in recycling streams loses a significant portion of its value and creates a contamination challenge that impedes the recovery of valuable recyclable materials. Cross-contamination of the recycling and composting streams is an expensive operational challenge and would pose significant risk to both industries. Brands that have set ambitious sustainable packaging goals are also impacted by inadequate collection and processing of these materials.

Our recommendation: Brands and municipalities should work together on educational campaigns and clear, on-pack messaging.

• Up to 50% of respondents say they would place packaging labeled as “made from plants” in the composting bin

“Made from plants” describes the materials used to make the packaging, not where the package should go at the end of its use. In fact, “made from plants” claims are commonly found on plastic packaging that should be recycled (i.e. PET made from ethanol derived from corn). Our study found that American consumers are especially confused by products and packaging that are not actually compostable yet have green or natural coloring, green tinting, or make claims such as “made from plants” without any context or disclaimer language. These plastic, non-compostable materials are virtually indistinguishable from their compostable counterparts.

Our recommendation: Brands and policymakers should support labeling policies that standardize clear, consistent consumer communications, design and labeling.

• Adding a trusted certification logo and larger “compostable” call out increases consumers’ ability to identify packaging as compostable by up to 22%

Our study finds that using at least two to three design elements that call out compostability on food-contact compostable packaging, such as the BPI certification mark, the intentional use of tinting and coloring, and a more prominent “compostable” call out, is most effective for consumer understanding.

Our recommendation: Brands and manufacturers should refer to the Composting Consortium’s latest report and BPI’s Industry Labeling Guidelines for specific examples of packaging design strategies that improve consumer identification, increase recovery of compostable materials and mitigate contamination at facilities.

Coming this month: A new report from the Composting Consortium on contamination rates at different composting facilities! Sign up for a webinar to learn about our findings here!

Without standardized labeling, misleading designs and claims will continue to cause consumer confusion. This research provides insights to brands, manufacturers, consumers, policymakers, municipalities, composters and other stakeholders on effective design and labeling techniques that could improve the diversion of food-contact compostable packaging to the right material stream. While these new findings shed light on the issue, this is just the beginning. As the composting space rapidly evolves, complementary studies will be critical to advancing the recovery of compostable packaging––a critical path to reducing food waste and greenhouse gas emissions.
