Sustainability and biobased content of Eastman cellulose esters
for formulated products

Eastman cellulose esters for formulated products are based on cellulose, one of the most abundant natural renewable resources, from trees harvested from sustainably managed forests.^a The trees are sourced from suppliers in multiple geographic locations, complying with the standards of internationally recognized forest certification programs, such as Forest Stewardship Council® (FSC®) and/or Programme for the Endorsement of Forest Certification (PEFC). Eastman also holds both FSC (license code FSC-C140711) and PEFC Chain of Custody certification, ensuring the traceability of the wood pulp sourced to make Eastman cellulose esters.

The FSC Chain of Custody certification traces the path of products from forests through the supply chain.

The PEFC Chain of Custody is a process for tracking forest products from their place of origin through all stages of transfer and production to the final end-product used by the consumer.

^aA few Eastman cellulose ester products are manufactured from other sustainable sources of cellulose.

A renewable backbone of new carbon

Eastman cellulose esters are polymers with a renewable backbone derived from one of the most abundant naturally occurring biopolymers––cellulose obtained from cotton linters and wood pulp. Eastman’s range of cellulose esters for formulated products has approximate new carbon calculations ranging from 36% to 63%. The percentage of new carbon is the differentiator for carbon-based substances contained in living organisms compared to carbon-based substances from fossil sources. The use of carbon from living organisms such as trees and crops can help create a neutral carbon footprint. See our sustainable wood sourcing policy for more information.
