PET Research

Choose the route around material quality and the next use.

PET is used in beverage bottles and other packaging. Its suitability for recycling depends on composition, contamination, processing history and the intended application.

Industrial PET recycling: contamination and process choice

Bottles, trays and other PET-bearing packaging need characterisation before they are treated as the same feedstock. Sorted material, washed flakes and further processed recycled material represent different business roles.

Recycled content: keep experimental findings in context

Technical findings depend on the material and processing conditions tested. A universal two-or-three-cycle limit is not a sound basis for PET decisions.

PET degradation: understand processing conditions

Simulated recycling studies help explain degradation mechanisms. They guide questions for material testing, rather than establish a proposed facility’s performance.

Multilayer PET: assess impurity effects

Impurity content can influence processing and output quality. Buyer requirements and representative samples should guide the assessment.

Food-contact PET: a separate validation pathway

Food-contact applications require a distinct validation and authorisation pathway. Washing and melting alone do not establish food-contact suitability.

Test for the intended application.

We will use actual material samples and buyer specifications to assess the product route before selecting a processing role.
