Countries in the World Solve Garbage Problem Program

With the increasingly accelerated pace of urbanization, the urbanization process in China face problems are increasingly serious waste Siege. Of a buried, one burned it, is not the best way, China needs to establish a comprehensive set of reasonable and effective treatment system.
With the increasingly accelerated pace of urbanization, the Chinese cities are facing are increasingly troubled by the garbage Siege severe. Not long ago, garbage disposal plants in Panyu, Guangzhou and Hong Kong, Tseung Kwan O landfill expansion plan has met with local residents protested, and from the angle of reflection of a municipal solid waste in China to resolve the dilemma requires new thinking and open up new ways.
From the perspective of social development, urban garbage treatment facilities and other offensive to public facilities, even if not residents, will eventually be the construction site. However, the one buried, one burned it, is not the best way, China needs to establish is a set including waste reduction, landfill, incineration and the separation and recovery, including reasonable and effective integrated treatment system.
Throughout the world, with the consumption level, the city difficult to contain growth in the number of garbage, waste disposal have significantly increased the workload and difficulty. However, according to the waste treatment technology is relatively advanced countries such as Sweden, Japan and Brazil, the practice point of view, taking into account the interests of social development and the residents there are tracks to follow.
First of all, from the source to effectively reduce the amount of waste, called a more environmentally root. In some areas overseas, is certain to require tenants to buy plastic bags to load litter, waste more, larger and more plastic bags to buy, would pay more, intended to impact on their wallets, to enhance waste awareness and motivation. If the garbage fee is only part of the management fees, the public will not have a strong feeling "painful experience."
Second, efforts to increase waste recycling, will be able to effectively reduce environmental pollution and reduce energy consumption. For example, Guangzhou city center of garbage generated every day, only to be burned into a generation; kitchen waste into more than four; followed recyclable paper, plastic, glass and metal. Slag stone really need landfill accounts for soil and other inorganic Jinliang Cheng, through an integrated approach can also be effective in reducing. After the integrated treatment of Zhongshan City, Guangdong Province, the total landfill volume of only one of the original into the trash, effectively reducing the harm to the environment.
Comprehensive recycling a key problem, it is garbage, because people's awareness of garbage is not high. Brazilian Government realistic, does not require residents to implement detailed classification of garbage, but only requires them to dry and wet waste into two. Residents need to follow the weight of wet waste dumping to the government payments, dry waste is free of charge. Wet waste by the government department responsible for processing, or composting, or landfill, scavengers of dry waste is handed over to cooperatives, so that they are responsible for separate collection, save a lot of investment to a certain extent, ease the labor employment. The Government of Sweden from the eighties of last century to the present, the time spent training a generation the concept of classification of waste initiative, has provided a guarantee for the long-term stability.
Of course, it is not recyclable rubbish, or the inevitable focus on incineration, which requires as much as possible by improving the processing technology to less pollution. Gothenburg, Sweden, a large waste treatment plant using very advanced equipment, incineration recycling of dry waste can not be said to waste ninety-eight% can be turned into energy, factory chimneys smoke is harmless water vapor. |
