Preparations and application of dust suppressants from biomass-based materials.

Both natural and anthropogenic fugitive dust can cause serious hazards to the environment and human health. In this study, the development of biodegradable dust suppressants and their environmental impacts were evaluated. Biodegradable dust suppressants were prepared using various biomass-based polymeric materials such as crude glycerol (a by-product of biodiesel manufacturing), biodiesel, palm oil, cooking oil, seaweed mixtures, wakame (a), and red algae.
