Vermi composting
Solid Waste Disposal for Biodegradable Component
The question asks for the appropriate method to dispose of the biodegradable component of solid waste. Biodegradable waste consists of organic materials that can be decomposed by microorganisms.
Vermi composting Method
Vermi composting is the biological decomposition process that uses specific species of earthworms to break down organic matter. This method is highly effective for treating the biodegradable fraction of solid waste, converting it into nutrient-rich compost.
- It directly addresses the organic and decomposable nature of biodegradable waste.
- It produces a valuable soil amendment (vermicompost).
Other Disposal Methods
The other options are less suitable for the direct disposal of the biodegradable component:
- Gasification and Pyrolysis: These are thermal processes that convert waste into gas or liquid/solid fuels. While they can handle mixed waste, they are energy-intensive and primarily used for energy recovery or waste reduction, not specifically optimized for biodegradables.
- Recycling: This process involves collecting and reprocessing materials (like plastic, glass, metal, paper) to create new products. It is not applicable to organic, biodegradable waste.
Therefore, vermi composting is the most suitable method for the disposal of the biodegradable component of solid waste.
