Resource recovery potential and industrial application of degradation products.

Degradation conditions	Main recycled products	Recovery potential	Possible industrial application directions
High temperature (800°℃)	Chlorinated aromatic hydrocarbons, carbon dioxide (CO2), metal oxides	High	Chemical raw material recovery (such as chloride treatment), energy recovery
Medium temperature (600°℃)	Dichlorobiphenyl, trichlorobenzene	Secondary	Fuel recovery, solvent recovery
Low temperature (400°℃)	Trichlorobiphenyl, pentachlorodioxin	Low	Waste disposal (such as landfill, incineration)
Activated carbon catalysis (600°℃)	Pentachlorobiphenyl, trichlorobenzene	Secondary	Dechlorination treatment, recycling of chlorinated waste
Metal catalysis (800°℃)	Dichlorobiphenyl, CO2, hydrogen chloride	High	Exhaust gas purification, chemical synthesis raw material recovery
