Abstract
The invention relates to an aqueous composition for the suppression of dust, comprising 1) an anionic surfactant; 2) an amphoteric surfactant; 3) a Bacillus species; and 4) a carbohydrate-based feedstock on which the Bacillus can grow. The composition is capable of forming a foam. When mixed with dust, the composition, in particular the foam thereof, is effective in preventing the dust from becoming airborne. Further, when applied before grinding or milling a material, the spreading of dust during and after the grinding or milling is effectively prevented.
