Our progress
The responsible use of resources, systematic waste management and the development of circular approaches are important aspects of circularity. These approaches can help keep resources in use for longer, reduce reliance on fossil and other finite resources, and strengthen the resilience of raw material supply. As part of Evonik’s broader efforts in the area of the circular economy, we at the Smart Effects Business Line report the following progress:
| Indicator | 2025 result compared with the 2021 baseline |
|---|---|
| Specific production waste volume relative to production volume | -1% reduction |
| Share of circular raw materials (recycled and biobased) at selected sites | 60% |
Actions to achieve our progress
We are implementing a broad range of measures at our production sites. Here are some examples:
Use of bio-circluar/ circular raw materials
By working closely with customers and partners, we convert selected waste streams into secondary raw materials for further production. This can reduce the use of virgin resources and supports circular material flows where technically and economically feasible.
For example, ULTRASIL® eCO is produced at Evonik’s ISCC PLUS-certified site in Adapazarı, Türkiye, using the ISCC PLUS mass-balance system. This enables customers to attribute verified circular content to their value chains. Find out more about ISCC PLUS-certified ULTRASIL® eCO and about the mass-balance approach.
Another approach is the recovery and reuse of tetraethoxysilan (TEOS) byproducts from semiconductor production. Our TEOS recycling program recovers and refines TEOS byproducts from participating electronics customers and reuses the recovered material in silane production. In participating production processes, the TEOS recycling program is intended to reduce the amount of TEOS sent for disposal and the use of virgin raw materials. The effect depends on the recovered input material, recovery rate and process conditions. Find out more about the TEOS recycling program.
