Our city has begun to pay attention to the problem.As far as I know ,some rubbish is sorted and sent to different factories.Rubbish ,such as old newspapers and glass ,is recycled.
Some harmful rubbish is sent to a certain place and buried.Waste air is cleaned before it goes into the air.Waste water is treated before it is poured into rivers.
