Deasyl: for ecological and profitable processes

Founded in 2017 and based in Geneva, Deasyl is an ambitious start-up, convinced that green chemistry represents the future of chemistry. Provided it can be made economically competitive.

“At Deasyl we are convinced that green chemistry is the future of chemistry, it is an inevitable and necessary transition,” explains Salima Fassi, Vice President of Deasyl. “We are developing processes to replace polluting processes in the chemical industry (petrochemistry and fine chemistry), while being economically viable. This is of course an imperative. Our business model is based on selling our patents to industrialists in this sector.” Among the most advanced projects, Deasyl holds a patent for the manufacture of a sustainable biodiesel, which is in the industrialisation phase thanks to the support of Swiss funds. “Our product is different from others, which rely on complex, time-consuming, energy-intensive processes that are only profitable on very large production volumes. Our solution allows used oil to be converted into biodiesel at room temperature, using a circular catalyst.  Our solution is profitable even for small volumes. The idea is therefore to create small production units as close as possible to the needs, thus reducing all the costs linked to the logistics chain,” continues Salima Fassi. Numerous contacts have been made with industrialists “in Portugal and the United Arab Emirates, as well as with the biodiesel producers’ association in the United States.”

Other patents are currently being developed (Solketal, C-glycoside, Vanillin, etc.) to diversify the start-up’s business.

With around twenty engineers and researchers, Deasyl works in open innovation “we have established partnerships with universities such as Polytechnique Montreal, Chimie Paris Tech or the Jules Verne University in Amiens, with whom we are working on a biosourced C-glucoside… We are thus broadening Deasyl’s fields of expertise with the aim of developing innovative and ecologically virtuous solutions.”

Deasyl’s objective is clear and ambitious: “We want to replace petroleum-based chemistry with biobased chemistry.  We are developing low-energy solutions and recycling our production waste, such as glycerol from the production of our biodiesel, which we transform into Solketal, for example. In this way, we can offer manufacturers solutions that have a strong environmental impact and are economically profitable. These are the two conditions that interest the industrial world.”



We are members of the B4C cluster in order to be as close as possible to innovations in the bioeconomy. We regularly participate in events organised by the cluster. The network of members favours contacts with potential future clients or partners. Finally, we also take advantage of the regular communications that keep us informed of news in the bioeconomy.
