Current Question (ID: 17891)

Question:

$\text{The correct statement about domestic waste is:}$

Options:

1. $\text{Only biodegradable domestic waste can be used as manure.}$
2. $\text{Non-biodegradable waste should be sent to industries for recycling.}$
3. $\text{It can be disposed off in a landfill.}$
4. $\text{All of the above.}$

Solution:

$\text{Biodegradable waste can be used as manure.}$ $\text{Depending upon the nature of the waste, domestic waste can be segregated into two categories i.e., biodegradable and non-biodegradable.}$ $\text{Biodegradable waste such as leaves, rotten food, etc. should be deposited in landfills, where they get decomposed aerobically and anaerobically into manure.}$ $\text{Non-biodegradable waste (which cannot be degraded) such as plastic, glass, metal scraps, etc. should be sent for recycling.}$ $\text{The modern sanitary landfill is much more than a simple dumping ground, due to the fact that waste materials are handled in a more controlled fashion to preserve the quality of groundwater in the area.}$
