Abstract
Methods of recycling printer cartridges use special rail-type clips for reassembly of complementary halves of a printer cartridge, the clips comprising cutouts or gaps spaced along the length thereof which accommodate protrusions near the edges being joined. The invention allows for recovering these cartridges and avoiding the cost of discarding a fairly costly machine element while additionally avoiding the processing costs for rendering the cartridge into inert, non-polluting waste.
