Question
Which precautions are necessary for proper decomposition of domestic waste?
Solution
Domestic waste refers to the waste which is generated in our houses due to our daily activities. Domestic waste can be either biodegradable or non-biodegradable for example, vegetable and fruit peels are biodegradable whereas batteries, computers, etc are non-biodegradable. biodegardable products can be used for making composts which can be used in parks, plant pots etc. For non-biodegradable products, we need to practice the 3R's, and only after that, they should be discarded as waste. The 3R's are -
- Reduce- Reduce the amount of waste produced.
- Reuse- Reusing a resource in a new way before throwing it.
- Recycle- Making something new from a material rather than throwing it away.
