Waste management methods are very important to protect the environment as well as improve health and quality of lives of people. Programmes for capacity building in waste management and change in the attitudes among people has to be launched. The quantum of investment required for setting up waste management facilities in Kerala has to be well estimated by the state government. The Asian Development Bank (ADB) has come forward with a huge amount to help in setting up solid and liquid waste management units across India. Thus the acute waste management problems can be resolved by implementing such plans.
Importance of Landfill Units
The result of such plans can be seen by segregating and treating as much as waste as possible at the source level itself. Urban waste dumping can be stopped only with the help of landfill units. Locating landfills for such a purpose is a very difficult task in a state like Kerala where there is acute shortage of land. But we cannot in any way avoid setting up landfill units for waste treatment. Sparsely populated plantations are thus being explored by the state government as landfill units for waste treatment.
Selecting places for landfills
Local bodies have great difficulties in finding land for setting up waste treatment plants. However hard we try, there would be 10% to 20% of inorganic waste that can be treated only with the help of landfills. Seven such regional landfill units across the state have been selected for this purpose. Inorganic waste treatment for the towns and municipalities in the neighbouring districts will be commonly facilitated here. Each such unit would require about 300 acres of land. Such units would be located mainly in rubber plantations as rubber products are not being used to eat.Benefit of treating waste in landfills
Treating the waste in landfills reduce the impact it has on the environment and encourages recovery and recycling. The characteristic of the waste is changed here. A large amount of compost can be produced as a result of the waste treatment in such units. The compost produced from these units can also be used as manure for augmenting the productivity of rubber trees.
Selection of waste for landfills
Low level radioactive wastes must only be disposed at landfills. Certain wastes must not be send to landfills. These include:-- Liquid waste, also known as trade effluent
- Used tyres
- Infectious clinical wastes from hospitals, medical premises or veterinary establishments.
- Wastes having explosive, corrosive, flammable or oxidising characteristics.
