Dioxycle

Dioxycle is a Paris-based startup dedicated to transforming industrial carbon emissions into sustainable products. Co-founded by David Wakerley and Sarah Lamaison, the company focuses on utilizing carbon dioxide to create a more sustainable society, moving away from fossil fuel extraction. The company's main innovation is an electrolyzer that converts carbon dioxide emissions into ethylene, a widely used organic chemical. This process employs renewable electricity, offering a cost-effective and environmentally friendly alternative to traditional ethylene production methods. Dioxycle aims to reduce the petrochemical industry's reliance on fossil fuels, particularly in the production of ethylene, which is essential for various everyday products. Dioxycle has received significant support from major venture capital firms, closing a $17 million Series A funding round in 2023. The company is set to begin industrial-scale ethylene production soon, reflecting its commitment to making a substantial impact in the $200 billion-per-year ethylene market. With a growing team of 25 experts, Dioxycle is focused on promoting sustainable supply chains and reducing carbon emissions.
