TU Berlin Chemists Recycle Silicone Waste into Reusable Building Blocks with Up to 99% Yield

Silicones are prized for their thermal and chemical stability, but those same properties have made them notoriously difficult to recycle. Now, researchers at the Institute of Chemistry at TU Berlin have developed a method to break down silicone polymer chains into their basic building blocks, achieving yields of up to 99%. The key product, dimethyldichlorosilane, can be directly reused as a starting material for manufacturing new silicone compounds. This breakthrough addresses a major gap in the circular economy for a material used across industries, from medical devices to everyday consumer goods. By turning waste into high-purity feedstock, the process reduces reliance on virgin raw materials and cuts environmental impact. The team’s work, published in a peer-reviewed journal, demonstrates a scalable and efficient route to silicone recycling. As global silicone production continues to rise, such innovations are critical for sustainable material management. The next step is to optimize the process for industrial application, potentially transforming how silicone waste is handled worldwide.
