Researchers at the T. Gorbachyov Kuzbass State Technical University (KuzTU) in Siberia have come up with new sorbents to remove oil spills from rivers, lakes and seas both in the temperate and Arctic climates. In their experiments earlier this year, industrial waste was used as raw material for such sorbents.
“Magnetic controllability and buoyancy are the key advantages of this innovative crude sorbent. At the core of it is a magnetite nucleus that helps attract oil film from a water reservoir and control it for efficient spill riddance,” Associate Professor Elena Ushakova, PhD, of KuzTU’s Chemical Solid Fuel Chair who runs the project was quoted as saying.
The oil-drawing technology feeds on simple waste that comes in plenty from coal mines (numerous in the region), cattle farms, timber companies, or sewage treatment facilities.
The Kuzbass sorbents were believed to work fine at very low temperatures, facing strong winds, and even in under-ice conditions, which makes them good enough for use in the Arctic and similar environments.
