Study Notes

Part I - Selection/Re-use & Recycling of Materials

  • Freecycling: Recycling waste products by giving them to others for free.
  • Non-biodegradable, reusable material: Materials like glass can be recycled repeatedly without losing quality.
  • Materials cycle: A process involving raw materials, synthesis, processing, manufacture, assembly, application, and waste. The cycle is often represented as Earth → Raw Materials → … → Application → Waste → Earth.
  • Glass composition: Glass is typically made of soda-lime, and borosilicate, but not alkaline materials.
  • Creative Reuse: The purpose of recycling used waste product
  • Deconstruction: Is a form of reusing existing materials; it involves breaking down items into their constituent components.
  • Recycling alternatives: Natural gas, trees, and mineral ores are natural resources used as substitutes for raw materials in recycling. However, geothermal heat is presented as an exception.
  • Reuse types: Downcycling, a type of reuse, is mentioned. It is distinguished from recycling and demolition.

Part II - Specific Recycling Questions

  • Polypropylene recycle code: The recycle code for polypropylene is 5.
  • High-density polyethylene recycle code: High-density polyethylene (HDPE) has a recycle code of 2.
  • Polysterene recycle code: The recycle code for polystyrene is 6.
  • Waste hierarchy second option: The second option in the waste hierarchy is reuse.
  • Closed system: The environment, in terms of material resources, is a closed system.
  • Typical recycled materials: Iron and steel scrap, aluminum cans, and glass bottles are often recycled.
