Performance evaluation and application of second-generation environmentally-friendly composite dust suppressant in dust control

Abstract

Abstract This study compares the performance of two generations of environmentally friendly composite dust suppressants, derived from plant straw, with two commercial suppressants, water, and dust-proof netting. The aim is to address construction-related dust pollution while minimizing environmental impact. Through wind erosion resistance tests under simulated high-wind conditions, the second-generation suppressant at 2 L/m2 concentration is found to decrease the soil mass loss, outperforming others in efficiency. Furthermore, a study on cabbage seed germination and growth under the influence of different solutions shows that the second-generation suppressant exhibits virtually no adverse effects, with results similar to water. In soil impact tests, the second-generation suppressant demonstrates the best solidification effect, with soil parameters meeting standards and outperforming both commercial suppressants and water. Overall, the second-generation environmentally friendly composite dust suppressant has shown favorable performance across all aspects, resulting in a suitable candidate for widespread use in dusty environments.
