secondary materials

Secondary materials are materials that are made from recycled or reused resources rather than being raw, natural materials. For example, recycled paper, plastics, or metals that have already been used in products and are processed again to create new items. Using secondary materials helps reduce waste, save energy, and decrease the environmental impact associated with extracting and processing raw resources. They are essential for sustainable manufacturing, promoting a circular economy where materials are continuously repurposed rather than discarded after single use.
