(1) Waste characterization and inventory — identifying every waste stream generated, its quantity, and its hazardous characteristics, which everything else depends on. (2) On-site handling, storage and labelling protocols — compatible-waste segregation, secondary containment, and container/labelling standards to prevent reaction and release before off-site shipment. (3) Treatment and disposal technology selection — matching each characterized waste stream to an appropriate recycling, treatment or secure-disposal pathway. (4) A regulatory tracking, reporting and emergency-response program — manifest/chain-of-custody documentation from generator to final disposal, staff training, and a contingency plan for spills or releases.
