Statistics

  • Globally, only around 5% of plastic is recycled. [1]

Basics

  • The Recycling of Plastics
  • Given that they can chemically degrade due to various mechanisms, or become dirty this is complex, but in most cases it is still very achievable
  • The main reason for the low amount of recycling is due to creating new plastic from Fossil Fuel feedstocks is cheaper, along with some other aspects like unclear collection/labeling systems
  • The process typically involves collection and sorting, washing, shredding, and drying
  • The resulting product is Shredded Plastic Flakes
    • These can be further processed, or used in this form

Internal Links

  • Precious Plastic (A group developing Open Source Hardware to allow for Decentralized Recycling of Plastics)
