Qingdao SOCO New Material’s DUSTSORB-202 marks a shift in dust control for waste management and outdoor industrial sites by substituting recurring water spray cycles with a polymer-based crusting layer that hardens into a three-dimensional matrix. The product is tailored for open stockpiles of municipal solid waste, construction debris, coal or biomass, plus haul roads and unpaved access tracks in hot, arid regions where fine particles can become airborne within hours of a water application. Field guidance issued by SOCO calls for dilution ratios between 1:30 and 1:50 and an application rate of 2.5–3.0 L/m² on static stockpiles, with dosage on roads adjusted for soil type, traffic loading and wind exposure.
The company’s spokesperson noted that “dust management is becoming a broader operational issue across industrial and material handling environments, especially in regions where water availability, community impact, and operating efficiency all matter.” Conventional calcium-chloride treatments rely on hygroscopic salts to draw moisture from the air, yet lose effectiveness when humidity falls below 30 % and temperatures exceed 35 °C. DUSTSORB-202 instead uses a non-corrosive, non-toxic polymer to lock fines in place without continuous re-wetting, reducing both water consumption and vehicle movements for re-spraying.
Early deployments on mining stockpiles and exposed slopes show the crust withstands wind gusts up to 60 km/h for weeks, curbing visible dust plumes at receptors beyond site boundaries. In waste transfer yards the crust also limits leachate evaporation by sealing the surface, indirectly conserving water that would otherwise be lost to the atmosphere. Operators report lower maintenance labor, fewer water bowsers on site, and less dust-related equipment wear compared with weekly spraying schedules.
