Post-industrial recycled content, also known as pre-consumer recycled content, is material waste generated during mass production that is later used to manufacture new products. Unlike post-consumer recycled content, post-industrial material has been recycled before entering into contact with consumers and being sent to a landfill. In order to claim post-industrial content, materials must be measured as a percentage in relation to their total weight. Use of either kind of recycled content offsets the need to manufacture virgin materials.
