Transforming CO₂ into raw materials and decarbonising industries: an encounter with Sarah Lamaison, co-founder of Dioxycle
The product of five years of research, Dioxycle has developed a technology that can recycle CO2 into essential chemical compounds. A pioneering start-up supported…
Key takeaways:
- Dioxycle has developed an electrolyser capable of turning CO or CO2 into ethylene (C2H4), a key chemical building block, currently produced from fossil derivatives
- This process could help reduce up to 800 million tonnes of CO2 a year, equivalent to the annual emissions of a country like Germany
- Participation in the Breakthrough Energy Fellows programme (Bill Gates) provided critical support to Dioxycle in validating its technology and structuring its industrial development.
You have developed a technology capable of turning CO2 into sustainable chemicals. How did Dioxycle come about, and how do your processes work?
Electrolysis, the key to the Dioxycle process
Electrolysis is a technology which uses electricity to cause a chemical reaction and transform one molecule into another. Dioxycle applies this process to carbon: its electrolyser is capable of turning CO or CO2 into ethylene (C2H4), an essential chemical building block used to produce plastics, textiles, and packaging. The process makes it possible to reduce dependence on fossil derivatives and recycle industrial emissions into useful resources, helping to decarbonise heavy industry.
