“…The results showed that the dust suppression efficiency increased with the EPS concentration. In addition, the adhesion effect of polysaccharides was greater during dust suppression [44]. As microbial dust suppressants are biased in application in previous studies, the time and maintenance mechanism of the dust suppression effect is still unclear, Geng et al [45] have analyzed the effective time and maintenance time of wind and rain corrosion resistance after the treatment of coal dust by microbial dust suppressors (MDS), established the coupling relationship between the consolidation characteristics of coal dust and its corrosion resistance, and discussed the key factors affecting the corrosion resistance effectiveness.…”

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.
