Demanufacturing is a process where a product after extensive usage, often at the end of its lifespan, 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, components that are deemed unusable are typically recycled to be used in new products. 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.
