Waste reduction involves efforts to reduce the use of resources and energy during production. For the same commercial products typically uses less material and less waste is produced. Waste reduction typically requires knowledge of the production process, from cradle to grave analysis (monitoring of materials from extraction to their return to the country) and a detailed knowledge of the composition of the waste.
