A reusable polyvinylchloride regenerate can be obtained from solvent containing PVC waste pastes by admixing same with acylpolyethylene glycol ester in a ratio of 1 part ester to 20 parts paste, adding water under mixing in an amount of about two times the weight of the paste, expelling the solvent with steam, removing the solvent from the resulting two phase distillate and filtering and drying the PVC granulate floating in the water phase of the distillate residue. The process provides for an environmentally responsible disposal and/or recycling of polyvinyl chloride wastes at low energy cost and chemical costs and independent of whether the wastes contain solvents, or are lacquer-like or pasty.
