Demanufacture is a process where a product after extensive usage is then disassembled into components, the components are classified as to functionality and components suitable for reuse are again to returned to a product for reuse. Demanufacturing was proposed to be used in all industries as a means reduce the environmental footprint while preserving economic viability of the processes involved. This term was first coined by Professor Walter W. Olson and Professor John W. Sutherland in 1993.
In the case of waste electronics demanufacture involves dismantling them into their components. In the case of material demanufacture this may be a chemical process, such as in treatment of waste plastics breaking down long polymers into smaller polymers.

Maczulak Waste Treatment: Reducing Global Waste 2010 1438126115 p.47 "The first step in dealing with waste electronics involves dismantling them into their components in a process called demanufacture. Demanufacture and recycling of the recovered parts can be thought of, collectively, as the treatment method for e-waste. Five to 10 percent of discarded computers undergo this demanufacture and are then fitted with new drives, circuitry, and ...."

Material demanufacture refers to the process of, e.g., breaking down long polymers into smaller ..."
