Recycling and Life Cycle Assesment
Why should we recycle
- Requires less energy than making new
- Preserves resources for the future
- Prevents material going into landfills
- Cheaper than making new
Problems
- Requires infrastructure to collect and sort materials
4 main stages of the LCA
Raw Materials
- Raw materials come from the Earth's crust/atmosphere or oceans
- Obtaining these materials has an impact of the enviroment:
- Using up limited resources such as ores and crude oil
- Damaging habitats through quarrying, mining or felling trees
Manufacture
- Manufacture of products has an impact on the enviroment including:
- Land for factories
- Use of machines and people
Use
- Impact of a product on the enviroment during its use, depends on type of product
- Chair wouldn't have a significant impact
- A car would though
Disposal
- Disposal of old products has an impact on the enviroment including:
- Land for landfill sites
- Whether the product can be recycled/reused
