Introduction to the Mass Balance chain-of-custody model and its developing application for LCA and EPDs

DATE: Thursday, December 4th, 2025

TIME: 1pm - 2pm EST

PRESENTER: Jason Pierce, Eastman Chemical Company

DESCRIPTION:

The mass balance credit method is a chain of custody (CoC) model which has generated both significant interest and controversy for application in LCA and EPD. Mass balance CoC model has been utilized in various industry sectors for decades but is experiencing significant growth via applications related to circular economy. There is a lack of guidance for LCA practitioners on how to integrate mass balance credit method CoC with LCA and EPDs. ACLCA is working to fill in the gap with the development of a mass balance chain of custody addendum to their Open PCR standard. The correct implementation of such guidance could better enable and encourage manufacturers to better utilize recycled content and other types of sustainability-focused inputs into integrated production processes.

This talk provides a basic introduction to the chain of custody topic with a focus on mass balance credit method including benefits, challenges, and recent developments. The session will include an update on the progress underway in the ACLCA mass balance working group.
