Environment:Waste Disposal

We discard large amounts of garbage every day. Are they all waste? Recycling is good way of treating our garbage. First, we deal with different garbage in different ways. We make a difference among paper, food, glass, steel, plastic, etc. Another way of recycling is to reuse some of the waste, like glass bottles can be used as vases; steel cans can be used to hold flowers, and so on.
