Sustainability is often difficult to achieve, particularly in urban areas. Urban areas have larger and denser populations, thus this causes environmental issues. For instance, a larger population creates more waste which needs to be disposed of. To improve urban sustainability waste needs to be managed. By producing less waste and altering the ways that waste is disposed of, the amount of resources used and the impact on the environment can be reduced.
It is estimated that every person in the UK produced 452kg of waste in 2010. Most of this waste was sent into landfills which is unsustainable. However, there is a decreasing use of landfills and an increase in recycling. For example, in 2004 33% of waste was recycled or composted compared to 45% in 2008. Landfill is when waste is dumped into old quarries or hollows, which is cheap in the short term but not sustainable. In the UK, landfill sites produced 36% of the nation’s methane emissions; this is not sustainable because greenhouse gasses cause climate change. However, there are developing technologies which allow the gases produced to be captured and used as a bio-fuel. In 2008, a landfill site in Mumbai captured the methane produced to generate electricity. This scheme is predicted to reduce greenhouse gas emissions by 2.2 million tonnes by 2028.
In developing countries, people often live and work on landfill sites,…
