New method lowers cleanup costs for persistent chemicals
Recent research has revealed an affordable method to reduce soil pollution caused by "permanent chemicals" (PFAS) resulting from the use of solid biological materials derived from wastewater. PFAS are substances that do not decompose easily and can persist in the environment for thousands of years. Their accumulation in soil poses threats to the health of living organisms, being associated with increased risks of cancer, cardiovascular diseases, and reproductive problems. The study indicates that removing these substances using conventional methods costs between $800,000 and $1.6 million per hectare, whereas the new approach is estimated to cost only around $29,000, while also improving soil health and reducing carbon emissions. This makes it a more cost-effective and efficient solution to combat ongoing pollution.
