  • How is PVC waste managed in China?
  • The management of PVC waste in China includes landfills, incineration, and recycling (Zhao et al., 2022). The proportions of PVC waste placed in landfills, incinerated, and mechanically and chemically recycled are respectively 36.0%, 9.3%, 25.5%, and 0.8% (Liu et al., 2020). However, there is limited landfill space, and the resource waste is high.
  • Does dechlorination play a role in chemical recycling of PVC waste?
  • The dechlorination principles of the chemical treatments were discussed. Significantly, dechlorination has played a key role in the chemical recycling of PVC waste. We explained the dehydrochlorination and dechlorination mechanisms.
  • What is the Chamber of the chemical and petrochemical industry?
  • The Chamber is a group of companies associated with petrochemicals, cereals and services. The Cubatão Hub Integration and Development Center is responsible for manufacturing high-quality raw materials. The Chamber of the Chemical and Petrochemical Industry represents companies in the chemical and petrochemical sector.
  • Which chemical treatment is used for recycling PVC waste?
  • Gasification Gasification is another chemical treatment for recycling PVC waste under an atmosphere of air/O 2 and steam. Gasification produces energy, energy carriers such as syngas (e.g., H 2, CO), and other chemicals (Lopez et al., 2018, Sansaniwal et al., 2017, Richardson et al., 2015, Abdoulmoumine et al., 2015).
  • Which fluid is used to treat PVC waste?
  • Sub- and supercritical fluids are used to treat PVC waste. The advantages are the enhancement of the reaction rates, reaction homogenization, and no limitation of mass transfer (Kubátová et al., 2002). Goto et al. (2009) reported that water and alcohol were employed in the depolymerization of plastic waste.
  • Does triethylene glycol increase the dechlorination efficiency of PVC?
  • Triethylene glycol (TEG) was used to increase the dechlorination efficiency of PVC (Kameda et al., 2009). Lu et al. (2019b) conducted dechlorination of PVC waste (e.g., waste sealing strips and cable coverings) in NaOH/EG solutions. Dechlorination ratios of 99% and 92% were achieved.
