PVC SPI code, for recycling (Society of the Plastics Industry). The Unicode character for this symbol is U+2675 (HTML character reference ♵).
Recycling of post-consumer PVC is technically feasible. The costs of recycling clean and homogeneous waste streams are generally acceptable. Rigid PVC can be recycled into pipes and profiles. Some PVC manufacturers have placed vinyl recycling programs into action, recycling both manufacturing waste back into their products, as well as post consumer PVC construction materials to reduce the load on landfills. Traditionally, PVC has not been recycled because the cost of virgin resin has been lower than recycling the resin.
The thermal depolymerization process can safely and efficiently convert PVC into fuel and minerals. It is not yet in widespread use.
A new process of PVC recycling is being developed in Europe called Texiloop. This process is based on a technology already applied industrially in Europe and Japan, called Vinyloop, which consists of recovering PVC plastic from composite materials through dissolution and precipitation. It strives to be a closed loop system, recycling its key solvent and hopefully making PVC a future technical nutrient.
