Briefings

Researchers at TU Berlin successfully decomposed silicone polymer chains into dimethyldichlorosilane, a reusable building block with up to 99% yield. This breakthrough addresses the thermal and chemical instability of silicones, enabling their recycling into new industrial compounds. The study represents a significant step toward circular economy solutions for waste management in the chemical sector.

Key points

• Researchers at TU Berlin decomposed silicone polymer chains into dimethyldichlorosilane, a reusable starting material for new silicone compounds.
• The process achieves up to 99% yield, significantly improving upon previous recycling limitations.

Context

Silicones are widely used in industry, medicine, and everyday products due to their exceptional thermal and chemical stability, which makes recycling extremely problematic. This study provides a method to break down these stable molecules into basic building blocks for reuse.

Limitations

Evidence is limited to the TU Berlin Institute of Chemistry research published in October 2026. The specific industrial scale of the process, long-term stability of the recycled dimethyldichlorosilane, and environmental impact of the production method remain unverified.
