After reviewing the importance of plastic and metal lets put some data and precise benefits of the it’s recycling process, as we saw for the papel and glass recycling:

BENEFITS OF RECYCLING PLASTICS AND METALS

Here’s a summary of the main benefits of recycling plastics and metals:

  1. Energy saving: Production using recycled packaging represents an 84% energy[1] saving in plastics, 95% in aluminum cans and 75% in steel cans, compared to the energy needed for production from virgin materials.
  2. Reduction in need for raw material: For every ton of recycled plastic containers around 1 ton of oil[2] is saved. For every ton of recycled aluminum, you save 6 tons of bauxite (element from which aluminum is made)
  3. Savings in resources: All of the packaging recycled could supply the plastic manufacturing industry with almost 9% of the resources[3] that it needs
  4. Improving air quality by reducing pollution: Aluminum recycling represents a reduction in emissions[4] of 9.8 tons of CO2 and 64kg SO2
  5. Savings in greenhouse gas (GHG) emissions
  6. Less waste is sent to landfill or for incineration

Plastic and metal recycling saves a lot of energy, reduces the consumption of resources (oil) and GHG emissions as well as improving the air quality

For 1 ton of packaging, and every year we generate more:

  • You save 1 ton of oil (from one ton of plastic packaging)
  • From PET bottles there’s a net benefit in greenhouse gases of 1.5 tons of CO2 equivalent[5]
  • Recycling 1 ton of aluminum saves 6 tons of bauxite, 4 tons of chemical products and 14,000 kWh of electricity[6]
  • Recycling 1 aluminum can save enough energy to run a TV for 3 hours[7]
  • Recycling 1 PET plastic bottle saves enough energy to run a TV for 20 minutes[8]
  • Recycling 40 bottles of water (PET) can make a polar fleece[9]
  • Recycling 80 cans of soda can make a bicycle tire[10]
