At the 49th International Exhibition of Inventions of Geneva recently held in Switzerland, a project on "the preparation of adsorption and separation functional composite materials of agricultural waste straw" won the silver prize.

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.

The International Exhibition of Inventions of Geneva is one of the world's biggest invention exhibitions and the world's largest innovation exhibition. All the exhibited inventions will be evaluated by international expert teams.

At the 49th exhibition, more than 1,000 inventions from over 40 countries and regions were exhibited.
