Environmental impact of PCB cleaning chemicals
Assessing environmental risks
Consider: biodegradability, aquatic toxicity, VOC emissions, and hazardous wastes generated. Solvent disposal and air emissions carry higher environmental and regulatory cost.
Quantify impact with life cycle analysis and monitor effluent composition for metals, chelants, and surfactants.
Choosing eco-friendly options
-
select biodegradable surfactants and low-VOC solvents;
-
use solvent reclamation or aqueous wastewater treatment to reduce discharge;
-
implement closed-loop processes and minimize makeup chemicals.
ZESTRON offers green chemistry options and guidance on effluent treatment to lower environmental footprint.
