Atratus's Living Fabric: fique cloth seeded with oil-eating bacteria cleans spills

Colombia's decades of armed conflict left a quieter scar: according to UNEP figures cited by the team, more than 1,000 significant land-based oil spills occur every year, contaminating millions of hectares, destroying habitats and threatening over 1,300 species. Conventional cleanup was expensive, slow and sometimes harmful to the very land it was meant to save.

The answer came from microbiology. Lysinibacillus sphaericus is a naturally occurring bacterium that biodegrades hydrocarbon molecules, turning oil into simpler compounds and releasing nitrates that restore fertility. After two years of testing, Atratus — working with the University of the Andes and VML Bogotá — embedded those bacteria in biodegradable fibres from fique, a native Colombian plant, producing Living Fabric: a rough, burlap-like textile that can be rolled out over contaminated ground.

Lightweight and portable, a box holds 33 square metres of the material, so crews can reach remote ecosystems without heavy machinery or supply chains. Where the fabric meets oil, the bacteria feed and the soil recovers in under 30 days. Rather than patenting the process, the team released it open source, so any organization anywhere can grow the fibres, inoculate them and deploy them locally.
