“Materials management is an approach to using and reusing resources most efficiently and sustainably throughout their lifecycles. It seeks to minimize materials used and all associated environmental impacts.”

Increase to 100% recycling nationally yields:
– 450 million metric tons of greenhouse gas reductions per year
– Includes all municipal solid waste MSW and construction, remodel, and demolition debris.

Shipping bags – even if made from virgin resources and not recycled – have lower environmental burdens in most categories than cardboard boxes – even if the boxes contain high levels of recycled content.
