Source reduction is activities designed to reduce the volume, mass, or toxicity of products throughout the life cycle. It includes the design and manufacture, use, and disposal of products with minimum toxic content, minimum volume of material, and/or a longer useful life. 
The term is also used to describe measures to reduce or eliminate breeding places for disease-carrying mosquitoes.
Synonyms.
Pollution prevention and toxics use reduction are also called source reduction because they address the use of hazardous substances at the source.
Procedures.
Source reduction is achieved through improvements in design, production, use, reuse, recycling, and through environmentally preferable purchasing (EPP). A Life-cycle assessment is useful to help choose among several alternatives and options.

These principles apply regardless of whether a term like "source reduced" is used.
The Massachusetts Toxics Use Reduction Program (TURA) offers six strategies to achieve source reduction:
