biodegradable acetate

The Opportunity

Cellulose acetate has overtaken the premium eyewear industry. The make up of acetate is already largely plant based, but conventional acetates usually have plasticisers which release toxic chemicals when they biodegrade. Biodegradable acetate uses bio-based plasticisers made from renewable sources and ensures that premium hand feel, look and quality.

b33 is a bio acetate material sourced from Asia which is used to create sustainable handmade eyewear.

Composition & Production

This material is made of pulp and fibres from cotton seed, conifer and wood from broad-leaved trees.

Responsible processing requires significant and ongoing cleaning of facilities or separate production lines, storage and management of bio-acetates, to ensure end-product can pass all testing. bbase offers production processes that handle acetate without risk of phthalate contamination. 


BPA Free 

Biodegradable (biodegrades after 115 days)

Medium product wastage throughout the process
