Waste is a symptom of an inefficient process . Waste is material and supplies that are paid for and subsequently rendered useless. Waste is costly. Businesses pay to collect and haul away waste. Getting more use out of material and supplies reduces both waste and cost.
Businesses lease or build office and storage space to store materials and supplies.
If less materials and supplies are needed, less storage space is needed and cost is reduced. Reducing waste increases profit. Reducing waste reduces needless consumption. Reducing needless consumption preserves renewable and non renewable resources. Reducing waste conserves energy and reduces air, soil, and water contamination from needless production of goods and from fossil fuel powered transportation that delivers needless goods and hauls them away as waste.
