- - - - balance social, environmental, economic effect
      - mining ore
        
        useful material, money and jobs
        
        bad for environment, scars landscape,
        loads of energy needed
- - - - Bioleaching
        
        Biacteria coverts copper compound in ore to soluble
        copper compounds, seperating them in the process
        
        forms leachate extract by
        
        electrolysis
        
        displace with more reactive metal. e.g scrap Fe
      - Phytomining
        
        growing plants in soil that contains copper
        
        plants cant use copper so builds up in leaves
        
        plant harvest, dried and burned in furnace
        
        ash contains soluble copper compound
        
        electrolysis or displacement
      - not as damaging but slow
- - - - Extracting can damage local environment
        & energy needed, eg. mining
      - processing large energy, extracting metal from ore,
        fractional distillation of crude oil
    - - can use lots of energy and cause
        pollution, e.g harmful fumes
      - waste products and how to dispose them. Sometimes
        waste can be turned to useful chemicals
    - - e.g burning fossil fuels. Fertilisers can leach into
        streams and rivers damage to ecosystems
      - how long used for and how many times,
        more the better, less wastage
    - - disposed in ladfill, polutes land and water
      - Energy used to transport to landfil
      - may be incinerated, causing air pollution
  - - - show some impact
      - deliberately support company for
        positive advertisisng
- - - - E.g waste steel & iron kept together as both can be added to iron in a blast furnace to reduce amount of iron ore required
  - - - reshaped to bottles, jars
      - different purpose, insulating glass
        wool for wall insulation in homes
