Question

How can segregation of waste into biodegradable and non-biodegradable reduce the quantity of waste and can be utilised for generating sustainable energy?

Answer 1

Segregation makes waste management more focused. Separating biodegradable and non-biodegradable waste reduces the total amount of waste dumped in landfills, lessening the impact on the environment. One way to handle the separated garbage is as follows:

1. Composting: It is possible to turn biodegradable garbage into nutrient-rich compost. By keeping organic waste out of landfills, composting enhances soil health and lessens the demand for chemical fertilisers.
2. Waste-to-energy conversion: Gasification and incineration are two methods for using non-biodegradable trash, such as some plastics. This produces energy that is sustainable and less dependent on fossil fuels.
3. Anaerobic decomposition: Biodegradable trash, particularly organic waste, can undergo this process to create biogas, a sustainable energy source that can be used for cooking, heating, or generating power.
4. Effective waste management: Segregation promotes efficient recycling and recovery of materials from non-biodegradable trash while streamlining the reuse, recycling, and disposal processes.
