either in a single chamber or in the case of the ink supply cartridge of the invention in a companion chamber when the ink solids are depleted or a waste ink chamber is filled a mechanism may be triggered automatically or by operator control to remove the barrier previously preventing the combination of the ink and the absorbent when the toner and absorbent combine a solid is formed which solid may be shipped to a recycling plant or landfilled depending on the ability of the cartridge components to be accepted and be stable in a landfill environment referred to as u201c landfillability u201d the resulting solid may even be non leachable for example no more than 5 by weight total of dissolved adsorbed or absorbed material is not removed by ambient conditions such as 20 moisture content in soil at 20 u00b0 c over twelve months with the capacity of the absorbent at 8 5 for the material retained meeting stringent environmental standards by leachable it is meant that organic liquid will not be removed at a rate greater than 5 total weight of organic liquids per year when contacted with distilled water at 20 u00b0 c with a replacement rate of the water of 1 liter month 10 m 2 of surface area of solid containing the organic liquid in one embodiment ink or condensed carrier in an initial supply or.
