Wastes are substances that have no further economic use. This means that in carrying out of everyday activities we all have left with us that we no longer need or is of no more use to us. The issue of waste is relevant to everyone as some level of waste is generated by all in their day to day activities.
Of this about 40% of the waste generated is organic in nature i.e. is biodegradable and comes from a plant or animal source. Organic waste is usually broken down by other organisms over time and is also referred to as wet waste. Organic matter, if dumped in a landfill releases methane, a potent greenhouse gas with adverse effect on the environment and contributes to landfill leachate that can pollute underground water and even rivers.
Organic waste provides a good input into the environment if managed properly. I the rural areas, organic waste generated in households is fed to livestock and manure ploughed back into the farms to sustain crops. In urban areas, the situation is dire as organic waste is often lumped together with inorganic matter and dumped above ground with disastrous consequences. Throwing away organic waste represents a wasted resource that fills limited landfill space.
