Waste Disposal- In LEDCs
Transcript of Waste Disposal- In LEDCs
The challenges processing waste in LEDC cities
Poor countries struggle to dispose of large amount of waste created by rapid urbanisation because of:
Money- Simply can't afford to dispose of waste safely. Money is needed for more urgent problems, such as health care.
Infrastructure- LEDC's don't have the infrastructure needed.e.g. poor road settlements means waste disposal lorries can't get in to remove rubbish.
Scale- The problem of waste disposal is huge.
Human uses of Waste Disposal
Waste provides a resource and a means of making a living for many shanty residents in LEDC's.
Children and adults scavenge and extract materials and then reuse or resell them.
Food waste is fed to animals or used as a fertiliser on vegetable plots.
Many cities in LEDCs are urbanising rapidly.
So, it is difficult to deal with the huge quantities of waste that people produce.
Poorest cities in the world are shanty towns or slums, which are totally unplanned. This makes the collection of waste difficult.
Many of these cities have very low standards of environmental protection, this means that industries can get away with polluting the natural environment if they are creating employment.
This leads to the pollution of both water resources and the air.
Effective waste management strategies aid to minimise or avoid negative impacts on the environment and human health. The aims of waste management are to :
Conserve resources of water, energy, raw materials and nutrients.
Control pollution of land, air & water.
Improve health and safety
It also includes waste reduction strategies:
Case Study- India
Trash & garbage is a common sight in both rural and urban areas of India.
India's cities generate 100 million tons of solid waste a year.
Along street corners there are trash piled on top of each other.
Rivers & canals act as a garbage dump.
In 2000, India's Supreme Court enforced all Indian cities to complete a waste management programme.
This included household's collection of segregrated waste, recycling & composting.
Unfortunately this programme was ignored.
India's medical waste is dumped with regular rubbish, and that only half of there medical waste is correctly disposed of.
Sadly, solid waste landfill sites in India are overflowing and are poorly managed.
Case Study: India's Waste Management
In 2011, several Indian cities commenced on waste to energy project.
In New Delhi, they have introducted 2 projects. There aim was to turn the city's trash problem into a electricity resource.
Some cities & towns, such as, Pune & Maharashtra are introducing collection of solid waste, street cleaning operations and bio mining to dispose the waste.
