The merit of refrigerator is that it has a isolated space where garbage been frozen.
On one way, In our daily life, if we didn't recover the rubbish , it could cause pollution,
unnecessarily. For example , summer leftovers will issue moldiness and wasted pest , broken lamp,
will spread toxic gas.
On the other way, it is easy to clean up. And since it been frozen, the liquid waste will not be splashed when it be recovered.Also it can eliminate the smelly gas, completely.
