Photosynthesis-inspired process makes commodity chemicals

18/07/2022

A Northwestern University research team used a new method to convert acetylene to ethylene, a widely used, highly valuable chemical that is an important component of plastics. They use a process similar to photosynthesis that is much less expensive and less energy intensive.

Reusing odor-contaminated plastics

01/07/2022

In the Fraunhofer Cluster of Excellence Circular Plastics Economy (CCPE), the four Fraunhofer institutes are researching odor barrier skins for polymer compounds made from recycled materials. With special additives, odor barrier skins with a skin thickness of 0.25 mm can be effectively realized. The odor-contaminated plastic can be "packaged".
