ABSTRACT = {Dust is an environmental and health hazard. In this study, a new technology for dust suppressant is introduced
using soybean urease with an optimal cementing solution. Calcium carbonate is produced by soybean urease and
cementing solution, which bonds the soil particles towards a dust suppressant. A laboratory wind tunnel test is
carried out to examine its effectiveness and discover possible optimization solutions. Several factors, including
soybean meal concentration, cementing solution concentration, and volume of solution per unit area, are examined to quantify their influences on soil transport mass, evaporation ratio, evaporation rate, surface strength,
water retention ratio, and infiltration rate of soil treated by different dust suppressants. Field tests are conducted
to explore the performance of this method in the natural environment. The results show that compared with
other dust suppressants, the optimized soybean urease has the smallest evaporation rate, a moderate infiltration
rate, the largest water retention ratio and surface strength. The indexes of soybean urease for dust suppressant are
found to be better than traditional materials. In the natural environment, soybean urease has a stronger anti-disturbance ability. This study concludes that soybean urease dust suppressant has great application potential as a
cheap and green method.},
