Biodegradation

The generation of organic wastes, such as sludge from wastewater treatment plants and food waste, is an inevitable byproduct of human activity. In line with the Federal Pollution Prevention Act of 1990 and the principles of Green Chemistry, waste that cannot be prevented or recycled must be managed in an environmentally sustainable manner. Conventional waste management methods, including incineration and landfilling, pose significant environmental risks, such as greenhouse gas emissions and soil and groundwater contamination.

Electrochemical methods like electrocoagulation (EC) can remove a vast array of compounds from wastewater but are not ideal for emerging pollutants found at low concentrations (ng/L to μg/L). In contrast, enzymes are known to effectively target these pollutants, but their performance can be hindered in complex water matrices. This work explores a biocatalytic treatment assisted by electrochemical processes to remove two emerging pollutants, Bisphenol A (BPA) and Triclosan (TCS) from municipal wastewater.
