The project was jointly carried out by Guizhou Merit Environmental Technology Co and the School of Geography & Environmental Science of Guizhou Normal University.

The project aims to reduce environmental pollution and emissions of carbon dioxide caused by burning agricultural waste straws. The research team suggests preparing plant fibers with agricultural waste straw and extracting polysaccharide compound from the waste straw to prepare adsorption and separation functional composite materials to treat environmental pollution.
