Waste Management
- In 2010 each person in the UK produced 452 kg of waste
- Waste management in the UK is improving
- EU targets want 50% of household waste to be recycles by 2020
Landfill
- Cheap way of getting rid of waste
- Releases CO2 and methane, however new technologies that allow gases to be captured can be used
- Can pollute groundwater, can be specially lined to prevent this
- Waste valuable materials that can be reused or recycled
Composting
- Organic material can be composted by individuals or on a larger scale, 38% of household waste is organic material
- Household composting reduces cost
- Sustainable as reduces the amount going to landfill
- Has to be managed properly, sorted so that no metal is involved
Recycling
- Quicker and cheaper than making materials from scratch
- Uses less energy, 20 times less when making aluminium cans
- Reduces demand for new materials
- Relies on individuals and some people don't bother
- Initial investment is required
- Often is transported abroad to be recycled, in 2005 55% of paper was sent to China
Energy Recovery
- Burning of materials that can't be recycled to produce heat or electricity
- Produces CO2 but reduces fossil fuels
- The Energy Recovery Facility in Sheffield provides heat for 140 building in the city centre
Reduce and Reuse
- Can be done by individuals eg reducing the amount of junk mail you receive or by businesses by reducing the packaging on items
- Plastic bottles are easily reused by cans are not
