Garbage refers to all waste materials and other household waste produced on a daily basis.
Houseflies, mosquitoes, microorganisms, bacteria and other disease-carrying living organisms seek refuge in garbage heaps, which not only spread dirt but also provide shelter for them.
There are several types of waste:
- Domestic Wastes
- Industrial Wastes
- Agricultural Wastes
- Commercial Wastes
All waste, in any form, must be managed and disposed of properly if we are to remain healthy and keep the environment clean.
