Solid Waste Management

What is Waste Management?

The need to minimize waste generation rates and recover and utilize by-products of waste production is dictating the future of waste management practices.

The concept of integrated waste management significantly reduces the amount of waste being sent to landfill and the amount being incinerated by the use of composting and recycling. In the process useful resources such as natural fertilizers and electricity are produced. This replaces the concept ‘waste’ being replaced by the concept of waste as a resource. World populations are producing increasing amounts of waste material from our societies, particularly in the Developed World countries, mostly in the form of packaging, e.g. metal cans, paper and cardboard containers, and plastic wrapping. In addition, large amounts of unused food (biological waste) are also thrown away.

In times past, this waste did not cause a problem; food was fresh, or in reusable containers (bags and sacks) and organic waste was returned to the land. We are currently being buried in an avalanche of waste.

Types of Waste Disposal

Some of the methods of waste disposal are mentioned below.

  • Open burning.
  • Dumping into the sea.
  • Landfills.
  • Incineration
  • Composting

Dumping at sea is not an ecologically sound method of disposal. Incineration must be carried out properly to maximize energy recovery, and prevent the risk of toxic byproducts from plastics entering the atmosphere.
Land fill used to be considered a one-stop solution-bury it and forget it. This is not the case. Land fill needs vast amounts of land, usually near cities, and produces gas and leachate which may contaminate the land.
Composting is a good way of turning biological waste into a valuable, natural, and reusable resource. Segregation of waste into various types, e.g.-

  • Paper & cardboard
  • Clean wood
  • Glass.
  • Metal cans & containers (aluminium and steel)
  • Organic food scraps and garden waste (grass, tree clippings, etc.)
  • Clean builders rubble
  • Batteries & electronic items.

This can result in a significant reduction in non-usable waste. Some 70% - 80% of collected, recyclable waste can be reused, and not end up as land fill.
