Iran has recently synthesized a biomulch that is claimed to be able to stabilize the soil in dust storm hotspots with minimum ecological impacts. Mulching, which refers to applying a layer of material on the surface of soil, has long been used as a solution to prevent sand and dust storms all over the world. The most common type used in Iran to control high-density particulate matters and fine dust spread in the air is petroleum-based mulch whose ecological impact is still being debated.
