Potential sustainability benefits

Santoprene TPV Sustainability opportunities

As indicated in a Life Cycle Inventory study, by Franklin Associates, the manufacture of polypropylene (PP) resins has a lower environmental impact when compared to the manufacture of some other plastics including GPPS, HIPS, and ABS. These lower environmental impacts include:

  • Lower energy consumption,
  • Lower total CO2 equivalent emissions, and
  • Lower solid waste

*According to the “Cradle-to-Gate Life cycle Inventory of Nine Plastic Resins and Four Polyurethane Precursors” conducted by Franklin Associates for the American Chemistry Council (ACC) in 2011.

The use of PP resins may also offer potential sustainability benefits to part manufacturers such as:

Weight reduction
PP resins have a lower specific gravity compared to most engineered plastics. This can result in lower weight parts and components. For example, when PP parts are used in automotive applications they can contribute to lighter vehicles, potentially improving fuel economy and reducing greenhouse gas emissions. Moreover, thin walled PP parts may further contribute to overall weight reduction.

Recycling opportunities
As a polyolefin, scrap produced during parts manufacturing can be recycled.

Reducing raw materials and waste
The thinner wall parts and recycling opportunities offered by PP can allow for a reduction in raw material use and waste.
