Thermal depolymerization is a process in which thermal energy, under high pressure conditions and with the aid of water, is used to decompose organic molecules. It would, in theory, render plastics and epoxies present into usable oil. The resulting solids would have much higher concentrations of metals. The process is currently being used to convert turkey waste in to water, solid waste (mainly carbon) and oil.<ref>http://www.sovereignty.org.uk/features/eco/zwaste2.html Accessed November 25, 2008</ref> | Thermal depolymerization is a process in which thermal energy, under high pressure conditions and with the aid of water, is used to decompose organic molecules.

This process is effective in dealing with plastics, but offers no method of bromine recovery. Also the metal-laden slag generated would increase the metal content by weight, but would likely complicate the metal recovery process due to the high concentration of oxides. Therefore, no overall increase in recycling efficiency is expected.

Also the metal-laden slag generated would increase the metal content by weight, but would likely complicate the metal recovery process due to the high concentration of oxides. Therefore, no overall increase in recycling efficiency is expected. This process is widely lauded as the solution to organic waste, but does not suit the goal of maximum metal extraction. | ||
