Sarah Lamaison is the CEO and Co-founder of Dioxycle. 

Dioxycle is developing technology to produce sustainable ethylene from recycled carbon emissions. Ethylene is the world's most used organic chemical and it's a precursor to many everyday products including construction materials, plastics, and textile fibers. Indeed, it's a core feedstock for polyester.

Ethylene is also an enormous market at well over $100 billion. We were excited to learn from Sarah about Dioxycle as an example of a startup leveraging electrolysis to convert electricity, water, and carbon emissions into low carbon chemicals. Dioxycle announced a Series A of financing earlier this year with investors including Breakthrough Energy Ventures, Lowercarbon Capital and Gigascale.
