To calculate the amount of waste generated, collect and weigh the waste from home or classroom for a day. Separate it into biodegradable and non-biodegradable categories to understand the composition.

Many local bodies have mechanisms to treat biodegradable and non-biodegradable wastes separately. Biodegradable waste is often composted or converted into biogas, while non-biodegradable waste is recycled, incinerated, or sent to landfills.

Pesticides can have various impacts on human health, including potential toxicity and long-term health effects due to their accumulation in the body.

In most towns and cities, local bodies like the municipal corporation or resident welfare associations have systems in place for the collection of household waste. This often involves regular waste pickup services and sometimes segregation of waste at the source.
