Who We Are
LoopS is an environmental project built on a simple vision: give communities the tools to turn their organic waste into local, affordable and clean energy.
19 000 Eiffel Towers : that’s the mass of organic waste generated in Europe every year. Most of it ends up incinerated or landfilled, generating high greenhouse gases emissions and squandering resources. The existing recovery processes are expensive and unsuitable for cities.
We are designing a small-scale and affordable waste recovery process.
Our mission: make circular solutions accessible everywhere, for everyone.
We are currently entering a new R&D phase, in partnership with AgroParisTech's InnLabs, the European Center for Biotechnology and Bioeconomics, and partner companies committed to environmental protection. We are looking for a scientist and late co-founder to work with us in the early stages of development, and to lay the technical foundations of the project.
