Reporting on half a decade of composting industry impact

By

Over five years, Closed Loop Partners’ Center for the Circular Economy’s Composting Consortium has helped advance composting access, infrastructure and understanding of compostable packaging across the U.S.—supporting food waste diversion and the recovery of compostable materials at scale.

Through collaboration with more than 50 stakeholders across the composting value chain, the Consortium tested over 23,000 compostable packaging items in real‑world facilities, published 11 industry‑shaping research reports, and expanded access to organics recycling for nearly 240,000 additional households—bringing food waste and compostable packaging collection within reach for at least half a million more Americans.

This impact report captures how cross‑sector research, field testing, grantmaking and policy analysis helped replace fragmentation and uncertainty with clearer, system‑level insight into what it takes for compostable packaging and food waste recovery to work in practice. From the largest known field test of compostable packaging in North America to practical tools for municipalities, composters and policymakers, the Consortium’s work demonstrates the power of collaboration in strengthening composting systems—while also underscoring the critical conditions still needed to scale organics circularity nationwide.

years of industry collaboration

Closed Loop Partners' Center for the Circular Economy created a platform for collaboration that is very hard to come by. Because of their Composting Consortium, critical field research went further, faster––with sweeping benefits across the value chain.

Key Results From Our Collaboration

Replaced anecdotes with the industry’s largest data set

Closed Loop Partners' Center for the Circular Economy launched the Composting Consortium in 2021 to advance organics circularity and compostable packaging recovery. In 2022, the Consortium led the largest U.S. field test of certified, food-contact compostable packaging, evaluating over 23,000 units across six composting technologies and 10 diverse environments to improve understanding of disintegration variability. In 2023, these findings were donated to help establish the first open‑source disintegration database with the Compostable Field Testing Program.

Catalyzed composting infrastructure & increased circularity of compostable materials

Launched in 2025 with BPI and USCC, the Composting Consortium Grant Program funded eight municipal and composter‑led projects to advance acceptance of compostable packaging. A $200,000 investment expanded organics recycling access to nearly 240,000 U.S. households through efforts focused on access, capacity and education.

Helped shape the legislative and policy landscape

The Composting Consortium strengthened data and research on compostable labeling, Extended Producer Responsibility (EPR) and compost end markets. Its national labeling study with BPI directly informed NGO briefings and testimony supporting Colorado’s landmark labeling law to protect composters from contamination. The Consortium also published a comprehensive EPR reimbursement framework, developed with composters, to guide states and Producer Responsibility Organizations (PROs) in funding composting infrastructure and recovering compostable packaging.

Advanced industry best practices

The Composting Consortium field-tested ASTM standards D8618 and D8619, closing the gap between lab testing and real-world composting conditions and informing a forthcoming national field guide led by USCC and CREF. The Consortium's research established one of the first baselines for contamination types and costs, showing contamination management accounts for roughly 20% of composting operating expenses. Through a national survey with BPI, the Consortium also identified labeling best practices to reduce consumer confusion and improve circular outcomes for compostable packaging.

Built a collaborative ecosystem

The Composting Consortium built a national platform for collective action, uniting brands, composters, municipalities, NGOs, industry groups and academic institutions to tackle systemic challenges. In 2024, it launched the Composter Innovator Program and Municipal Partner Platform to elevate operator and city leadership voices in EPR policy and composting infrastructure best practices. Through this work, the Consortium fostered trust, credibility and lasting cross-sector relationships across the composting value chain.
