Background
Airborne dust emission can lead to adverse effects on human health (e.g., respiratory problems and cardiovascular issues) and the surrounding environment (e.g., contamination of water bodies and degradation of vegetation). One commonly used short-term method to mitigate airborne dust is spraying water on the soil surface. However, as the water evaporates and the surface dries, it becomes less effective, providing only temporary relief. Chloride salts, including Sodium Chloride (NaCl), Calcium Chloride (CaCl2), and Magnesium Chloride (MgCl2), are other widely used products that work because of their hygroscopic nature. However, chloride-based dust suppressants pose major concerns, including soil and water contamination, corrosion of automobiles and civil infrastructure, and reduction in agricultural productivity.
Invention Description
Researchers at Arizona State University have developed a biobased product that can be used as a dust suppressant in arid climates. This product is non-toxic, and the raw materials needed to synthesize this product are abundantly available in the USA. No special equipment is required, and existing tankers or de-icing vehicles can be used to apply this product. This product is compatible with chloride-based salts, and the combination may produce long-lasting results. The product has a long shelf life and can be prepared on-site for immediate use. Both the in-lab and field tests are very promising, as reflected in the reduced amount of particulate material entrained into the air. This product can be used in various settings, including construction sites, mines, fairgrounds, and agricultural fields. This product requires no soil preparation and is effective 30 to 60 minutes after application.
