Research Progress of Bio-organic Dust Suppressants

Abstract

Both natural and human-generated dust can cause serious harm to the environment and human health. Since the dust suppressants can accelerate the dust settlement more effectively to prevent the dust from raising; at the same time, to comply with the concept of environmental protection, the use of natural bioorganic materials to prepare dust suppressants has become a research hotspot. This paper summarizes the working principle of dust suppressants and the evaluation indexes of the performance of the dust suppressants, reviews the methods and research results of using bio-organic materials such as polysaccharides, lignin, proteins, microorganisms, agricultural and forestry wastes to prepare dust suppressants in recent years, and puts forward the suggestions on the problems of the current bio-organic dust suppressants to provide a reference for their further development in the future.
