About Biosorbe

Biosorbe is an efficient and environmentally friendly absorbent of hydrocarbons in water, air and soil. It replaces the plastic and oil-based alternatives that exist on the market today but can also clean where there are no suitable product alternatives available. The absorbed oils can be extracted and re-used, degraded into harmless components, or be incinerated.

The product is a result of a science project at the Royal Institute of Technology, KTH, and has been developed and commercialized by Biosorbe AB, with continued collaboration with KTH and the University of Karlstad.

Our revolutionary Swedish bio-based product absorbs oil spills both on land and in water. Biosorbe is a natural oil absorbent, as well as a hydrophobic water repellent–allowing it to resist rain on land or float on water for extended periods to collect oil from the surface.

Ekman is a global sales and marketing organization strategically aligning buyers and sellers of forest products around the world.

Every innovation starts with an idea. For Biosorbe, it all started 2005. Over the past few years the idea has been shaped into a world-unique environmentally friendly product.
