Behavior and products of mechano-chemical dechlorination of polyvinyl chloride and poly (vinylidene chloride)

Mechanochemical degradation of tetrabromobisphenol A: Performance, products and pathway

“…Compared with the traditional combustion technology, MC destruction does not require heating or off-gas treatment [24], which consumes less energy, emits less carbon dioxide, produces less waste, and can normally avoid the formation and release of unintentionally produced POPs such as PCDDs/Fs [22,25]. Studies on successful degradation of halogenated organic pollutants, such as DDT [26], halogenated benzene [27][28][29][30], PCBs [31][32][33], poly vinyl chloride (PVC) [34][35][36][37] and PCDD/Fs [38][39][40][41] by MC reaction have been reported.…”

A highly efficient approach for dehydrochlorinating polyvinyl chloride: catalysis by 1-butyl-3-methylimidazolium chloride

“…3 Moreover, dehydrochlorination is also an essential step in producing clean fuel oil when recycling PVC-containing waste plastics. 4 With respect to PVC dehydrochlorination, various methods have recently been developed, such as catalytic dechlorination using metal oxides or composite oxides, 5 mechanochemical dechlorination, 6 and hydrolysis in alkaline solutions. 7 The latter method is efficient but requires volatile and toxic solvents, and the resulting by-products, such as KCl, could cause secondary pollution.…”

Application of mechanochemistry to metal recovery from second-hand resources: a technical overview

“…These innovated dry-milling methods give a reference when it comes to the recovery method option in the future. Xiao's work 63 veried that zinc can be chlorinated by co-milling with PVC. So possible Zn recovery can be performed as shown in Fig.…”
