As a specialty chemicals company, the Group can count on extensive know-how in the area of specialties and additives to support this effort.

In testing: Olefin-based additive for recycling packaging films

In development: Alkoxides break PET bottles down into monomers

In the marketplace: Process additive turns old tires into rugged work material


Evonik is engaged in research and development work to come up with solutions for recycling plastics and rubber. As a specialty chemicals company, the Group can count on extensive know-how in the area of specialties and additives to support this effort. While developers are working on solutions for mechanical and chemical recycling of plastics, the company portfolio already includes a process additive for efficiently processing rubber waste, such as used tires, to generate a rugged work material.

Mechanical recycling involves separating and cleaning synthetic materials to directly reuse them as polymers. The challenge is, however, that this process affects the quality of the recycled material. Evonik is currently working with a large disposal company to optimize the recycling of polyethylene, which is processed in large quantities, especially in packaging films.

The Evonik additive Vestoplast®, an amorphous polyolefin that is primarily used in hot-melt adhesives, may be the key to making that possible. It can specifically improve the impact strength or flow properties of polyethylene, which may be helpful for reusing recycled plastic, for example in injection molding.
