Accelerating Circularity announced the release of its latest paper, Tipping the Scale: Mass Balance in Chemical Recycling, developed through the Alliance for Chemical Recycling (ACTR) working group. The paper offers a detailed look at how mass balance is being applied to track material flows and attribute recycled content across complex textile value chains.
Mass balance is a chain of custody model in which materials with defined characteristics are mixed with conventional materials under controlled conditions, with outputs attributed through verifiable bookkeeping. The approach is widely used in the textile industry and is an essential tool as a mechanism to support textile-to-textile recycling systems, where material complexity and global supply chains present ongoing traceability and scaling challenges.
This paper examines how mass balance functions in practice, including how inputs and outputs are tracked, how recycled content is accounted for, and what considerations are necessary to ensure credible implementation across the value chain.
“Tipping the Scales white paper was developed through our Alliance of Chemical Textiles Recyclers. We provide not only definitions but examples of how mass balance works in existing textile and other markets. With input from a variety of both polyester and cotton chemical textile recyclers it provides multiple perspectives on how mass balance supports the scaling of recycling technologies into the existing textile supply chain,” says Karla Magruder, founder and board chair, Accelerating Circularity.
“Mass balance can be a useful means to track and trace sustainable products throughout the distribution chain when inputs are mixed and physical segregation of material is not possible. At the LYCRA Company we support both dedicated production of sustainable materials and mass balance systems as ultimately, both will be required to meet the industry’s sustainability goals,” says Jean Hegedus, sustainability consultant, The Lycra Company
Accelerating Circularity will host a live discussion on April 28 from 9:30–10:30 a.m. EST, which will explore how mass balance is being implemented today and what it looks like in real-world systems.
