Arctic Oil Spills: New Sorbents Absorb Oil in Extreme Cold

Russian scientists have engineered advanced sorbents capable of tackling oil spills in the harsh Arctic environment. Developed by researchers from Togliatti State University and Yuri Gagarin Saratov State Technical University, these sorbents are designed to operate efficiently at extremely low temperatures.

The innovative materials are synthesized from recycled waste, including polyethylene terephthalate (PET), sawdust, and ferritized electroplating sludge. This approach not only enhances economic feasibility but also supports a circular economy by repurposing industrial byproducts.

Laboratory tests confirmed the sorbents' exceptional performance, absorbing over 99% of oil film within 20 minutes in simulated seawater conditions. Notably, at minus 5 degrees Celsius, their oil capacity reached 22 grams per gram of sorbent, significantly outperforming existing commercial products.

A key advantage is their magnetic property, which enables rapid and complete collection from water surfaces using magnets. This feature drastically reduces labor costs and the risk of secondary pollution, making spill response more manageable, especially in challenging icy conditions or near coastlines. The sorbents also demonstrate high stability and buoyancy, remaining effective on water for up to 96 hours.
