- Recycling
- Production loop - recycling process where industry uses wastes produced during the manufacturing processes
- Resource stabilization - use of more abundant materials instead of less abundant ones e.g. plastic instead of metal
- Most domestic waste can be recycled if separated before collection to prevent contamination
- Recyclables
- Paper
- Garden waste
- Electrics
- Plastic bottles
- Lead-acid batteries
- Recycling aluminum (can be applied to most materials)
- Waste losses - not all used materials are recyclable
- Transport - expensive
- Labour costs - expensive to process small amounts of material
- Separation - metal alloys cannot be separated easily so cannot usually be used
- Identification of aluminium composition - time-consuming and labour intensive
- Recycling saves extraction energy but creates transport energy
- Public cooperation requires to separate wastes
