A manufacturer may determine that using a CWT is more cost-effective than treating the waste itself this is often the case where the manufacturer is a small business. A manufacturer may send its wastes to a CWT plant, rather than perform treatment on site, due to constraints such as limited land availability, difficulty in designing and operating an on-site system, or limitations imposed by environmental regulations and permits. Centralized waste treatment Ī centralized waste treatment (CWT) facility processes liquid or solid industrial wastes generated by off-site manufacturing facilities. Pollutants generated at manufacturing plants includes cadmium, chromium, cobalt, copper, cyanide, iron, lead, manganese, mercury, nickel, silver, zinc, oil and grease. Battery manufacturing īattery manufacturers specialize in fabricating small devices for electronics and portable equipment (e.g., power tools), or larger, high-powered units for cars, trucks and other motorized vehicles. The specific pollutants generated and the resultant effluent concentrations can vary widely among the industrial sectors.
