Garbage is defined as items or materials that must be discarded because they serve no purpose for us or are no longer useful to us.
Tonnes of garbage are produced by us daily. Garbage is frequently associated with a strong odour, and a large amount of garbage may emit harmful fumes. As a result, we place such items in dustbins to be transported to distant locations, ensuring that our surroundings are clean and healthy.
Garbage should be processed by authorities rather than burned because burning garbage emits toxic fumes that are hazardous to everyone’s health.
Some waste management techniques include:
- Vermicomposting
- Landfill
- Reusing
- Recycling
