Introducing Retein.
Novel technology that enables precise and sustainable recovery of valuable resources from water, including the clean water itself.

Retein adapts Nature’s finest separation for use in the recovery of high purity resources like clean water and lithium, from any accessible water. Our patented molecular separation technology was developed at Chalmers University of Technology with the purpose of accelerating the transition towards a resource-efficient and sustainable world from the bottom up. We transform the supply of resources, enabling convenient access to sustainably sourced high-quality materials and in doing so, we reimagine a material-optimized world.
