Impervious

Recycling involves processing used materials into new products to:

  • Prevent the waste of potentially useful materials,
  • Reduce the consumption of fresh raw materials,
  • Reduce energy usage,
  • Reduce air pollution (from incineration),
  • Water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and,
  • Lower greenhouse gas emissions as compared to virgin production.
Recycling is a key component of modern waste management and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy.
