Waste Profiling

Do you profile your waste? Believe it or not, this is a high-priority task for many manufacturing companies. And, unfortunately, it is one environmental issue that commonly slips through the cracks. Profiling means to determine the characteristics of the waste, and determine whether it is hazardous waste or non-hazardous waste.
