3
New cards

incineration

reduces waste volume by 90% and can generate energy

releases toxic gases, requires high investments, public opposition

4
New cards

recycling

saves resources and reduces landfill usage

expensive, relies on public participation and proper sorting

5
New cards

composting

good for organic waste, reduces landfill pressure, produces natural fertilisers

requires space, time, public cooperation

6
New cards

waste-to-energy

combines incineration with energy recovery, reduces landfill usage

environmentally controversial

7
New cards

unregulated

soil and water contamination due to leachate, air pollution from burning, attracts vermin

8
New cards

recovery

reduces landfill usage, lowers demand for raw materials

9
