UniSieve, a spin-out of Switzerland’s ETH university, has developed technology that promises to save energy, reduce emissions, and increase product recovery during the processing of chemical feedstocks. It is piloting its system with some of the world’s largest chemical and energy companies.
Today 10% to 15% of the energy consumed globally is used for separating and purifying chemicals and gas used by the chemical, plastics, and energy sectors. Instead of using thermal energy UniSieve has developed modular filters which can be integrated into existing systems. Its approach uses 90% less energy, offering significant cost savings, says CEO Samuel Hess, who co-founded the company with Elia Schneider. What’s more the process recuperates valuable chemicals that end up being burned during traditional processing and reduces process CO2 emissions, he says.
