Chinanews, Beijing, Nov. 20 – There are a total of seven billion tons of garbage kept in Chinese cities and this garbage together occupies 600 million square meters of land space. Urban garbage has now become one of the four major polluting sources in China.China has 700 cities. Everyday, these cities produce 100 tons of garbage in total and the amount still increases by 8%-10% every year. In China, about two-thirds of the cities are surrounded by garbage. In many cities, the garbage is exposed in open air with no one to take care of it. The garbage not only damages the city's image, they also pollute the atmosphere, water and soil, and pose a threat to human health.China will face a critical period in its modernization drive in the fifty years to come. As urbanization process has quickened, the garbage in cities will become a serious problem to our human life and we should pay great attention to the problem, said Dong Suocheng, executive director of the China Resources Institute.In the next fifty years, China's population scale and urbanization process will reach its peak. In light of this, China should make great efforts to develop recycled economy. On the one hand, China should make sure that less garbage will be produced. On the other hand, China should make good use of garbage resources and turn garbage handling into an industry, and to make sure that garbage industry will cover every part of garbage processing, from garbage collecting and classifying to garbage transportation and treatment. This might serve as a good way to solve the garbage problem in cities, he said.
