As waste has four sorts, we can sort them into each sort
that they belong to. It’s convenient to treat them after
they are sorted. Then we can deal with them sort by sort.
We have thought out some methods like storing them in
order to change them into plant food, or burning them
in a huge stove and use the heat to make electricity. For
the first way, the change rate is much too low and it may
pollute the under ground water. For the second one, of
course it’s wonderful if it’s easy to be tried out. But to
build such a huge stove will cost too much. Not a good
method. Now you see, treating waste is not an easy job.
Outlines:

Samples
We have different ways to deal with wastes. The
wastes sorted into groups can be stored so that
they could change into plant food, or we can have
them burnt to make electricity. ①
