persistence

This is a measure of a substance's ability to remain as a discrete chemical entity in the environment for a prolonged period of time. A common measuring tool for persistence is "half-life" (t1/2), which is the amount of time required for half of the substance to break down. If halflife is greater than 30 days in the air, or if half-life is greater than 50 days in soil, water, or any other media, the substance is considered to be persistent.

point source pollution

Pollution that originates from specific, known sources such as municipal and industrial facilities, bypasses and overflows from municipal sewage systems, non-permitted and illegal dischargers, and water that is generated through oil and gas operations.

pollution prevention

Source reduction as defined in the Pollution Prevention Act of 1990 (42 U.S.C. 13102), and other practices that reduce or eliminate the creation of pollutants through: (a) increased efficiency in the use of raw materials, energy, water or other resources; or (b) protection of natural resources by conservation.

polyethylene terephthalate (PET)

A thermoplastic material that is clear, tough and has good gas and moisture barrier properties. Used in soft drink bottles and other blow molded containers, although sheet applications are increasing. Cleaned, recycled PET flakes and pellets are used in some spinning fiber for carpet yarns, fiberfill and geo-textiles. Other applications include strapping, molding compounds and both food and non-food containers.

Polyvinyl Chloride (PVC)

Synthetic thermoplastic polymer made from vinyl chloride. In addition to its stable physical properties, PVC has excellent transparency, chemical resistance, long-term stability, good weatherability, flow characteristics and stable electrical properties. However, its stability makes it nearly environmentally indestructible. PVC also releases hydrochloric acid and other toxic compounds when produced, used or burned.

post-industrial material

Recovered industrial and manufacturing materials that are diverted from municipal solid waste for the purpose of collection, recycling and disposition. Post-industrial materials are part of the broader category of recovered materials and include print overruns, over issue publications and obsolete inventories.

product of consumption

A product designed for safe and complete return to the environment, which becomes nutrients for living systems. The product of consumption design strategy allows products to offer effectiveness without the liability of materials that must be recycled or "managed" after use.

Product of Service

A product that is used by the customer, formally or in effect, but owned by the manufacturer. The manufacturer maintains ownership of valuable material assets for continual reuse while the customer receives the service of the product without assuming its material liability. Products that can utilize valuable but potentially hazardous materials can be optimized as Products of Service.
