Table 1 Former use of PCBs and disposal
From: The role of waste management in the control of hazardous substances: lessons learned
Type of PCB used | Type of Application | Intended way / normal way of disposal | Separation from other items | |
|---|---|---|---|---|
Isolating agent in transformers | Cl > = 54% | “closed” | Special waste | Easy |
Isolating agent in large capacitors | Cl < =42% | “closed” | Special waste | Easy |
Hydraulic fluid in mining equipment | Tri- and Tetra-CBs | “closed” | Special waste / waste water from mine draining | Difficult in underground mines |
Heat transfer oil in industrial applications | Low chlorinated mixtures | “closed” | Special waste | Easy |
Isolating agent in small capacitors | Cl < =42% | “closed” | Waste from electric and electronic equipment / household waste | Possible in state of the art sorting plants |
Additive to joint sealer | All technical mixtures | “open” | Hazardous waste / mixed construction waste | Possible in state of the art dismantling processes |
Additive to dyes | All technical mixtures | “open” | Hazardous waste / mixed construction waste | Nearly impossible |
Additive to textiles | Low chlorinated mixtures | “open” | Hazardous waste / household waste | Nearly impossible |
Additive to PVC | High chlorinated mixtures | “open” | Hazardous waste / household waste | Possible in state of the art sorting plants |
