Demanufacturing is a process where a product after extensive usage, often at the end of its lifespan, is then disassembled or dismantled into its components.
[1] Demanufacturing was proposed to be used in all industries as a means reduce the environmental footprint while preserving economic viability of the processes involved.
Au and Ag of printed wiring boards) and critical metal recovery (e.g. Nd from permanent magnets in HDDs).
In contrast Destructive demanufacturing relies on destructive dismantling techniques in which information on the product structure is used to define optimal cutting points, which are used to take the product apart and to separate specific components with a higher yield and concentration in support of material recycling.
The practice provides numerous jobs to people and communities; in addition business opportunities and reduction in environmental impact of component reuse and product remanufacturing is considered to encompass great potential.
