The primary method of managing biodegradable domestic waste after collection is _________________.
conversion into compost
The question requires identifying the most suitable method for managing biodegradable domestic waste after its collection. Let's evaluate each option:
- Burnt in open air: Burning waste in the open results in air pollution and is not an environmentally friendly or sustainable method. Therefore, this option is not appropriate for managing biodegradable waste effectively.
- Conversion into compost: Composting is the process of decomposing organic waste material into a nutrient-rich soil amendment, known as compost. This method is environmentally friendly, promotes recycling of nutrients, and effectively manages biodegradable waste. Hence, converting waste into compost is the correct method.
- Sending for recycling: Recycling is generally applicable to materials like plastics, metals, and glass. Biodegradable waste, which predominantly includes food scraps and garden waste, is not typically recycled but rather composted.
- Throwing into sewers: Disposing of waste in sewers can lead to blockages and pollution of water systems. It is neither a safe nor effective method for managing waste.
Therefore, the primary method of managing biodegradable domestic waste after collection is conversion into compost.
