by treatment with organic material

Introduced: January 1985

Full Title

Full titles differ between systems:

IPC:

Recovery or working-up of waste materials > of polymers > by chemically breaking down the molecular chains of polymers or breaking of crosslinks, e.g. devulcanisation > by treatment with organic material

CPC:

Recovery or working-up of waste materials (recovery of plastics B29B17/00; polymerisation processes involving purification or recycling of waste polymers or their depolymerisation products C08B, C08C, C08F, C08G, C08H) > of polymers > by chemically breaking down the molecular chains of polymers or breaking of crosslinks, e.g. devulcanisation (depolymerisation to the original monomer C07) > by treatment with organic material

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1985.
