Trederra recycled rubber

Trederra produces recycled rubber masterbatches designed to partially replace virgin synthetic rubber in footwear applications. The material is manufactured in Asia using both post-consumer and post-industrial waste streams.

One feedstock consists of rubber recovered from end-of-life tires. This Masterbatch MB1 has 67% recycled content and is particularly suitable for work and safety footwear outsoles where oil resistance is required.

A second feedstock uses pre-consumer or post-industrial waste, including EVA, latex, and polyol. Trederra’s MB-6 masterbatch contains 80% recycled content and is intended for performance and casual footwear outsoles. It can be blended with both natural and synthetic rubber to produce the final outsole compound. According to the manufacturer, MB-6 meets relevant physical performance requirements without restricting the color possibilities of the finished product.

A third-party life cycle assessment (LCA) commissioned by Trederra indicates that the

• Post-consumer end-of-life tire (ELT) recycled masterbatch MB1 can achieve a 27% reduction in CO₂-equivalent emissions compared with virgin rubber masterbatch.
• Pre-consumer recycled masterbatch MB-6 can achieve a 66.47% reduction in CO₂-equivalent emissions compared with virgin rubber masterbatch.

By incorporating existing rubber and polymer waste as a feedstock into new compounds, the material offers footwear manufacturers a way to reduce virgin rubber consumption while retaining the properties required for outsole production.

Trederra is a Global Recycled Standard (GRS) certified and Restricted Substances List (RSL) compliant.
