A method for the recycling of post-consumer plastic materials

A process for the recycling of a vinyl chloride polymer material which comprises an initial level of one or more additive compounds, the process comprising:

• (i). providing an aqueous acid composition comprising one or more alcohols and one or more acids,
• (ii). contacting the vinyl chloride polymer material and a volume of the acid composition to cause extraction of the one or more additive compounds from the vinyl chloride polymer material, wherein the acid composition forms a two-phase system with the vinyl chloride polymer material, comprising a solid phase comprising a purified vinyl chloride polymer material and a liquid phase comprising the alcohol, water, the acid and the extracted one or more additive compounds,
• (iii). separating the solid phase comprising the purified vinyl chloride polymer material and the liquid phase comprising the extracted one or more additive compounds.
