Page 4The comprehensive result of analysis is that the composting & landfill approach is abetter solution. To reconstruct crude dumping place into sanitary landfill and installbiogas waste treatment plant might be suitable technical solution for the case ofJingshan.Since municipal solid waste management is not just a question of technology, it isalso a matter of integrated approach which includes source reduction, sorting atsource, educating residents. An integrated approach is necessary and should beimplemented step by step. So, the suggested integrated approaches for Jingshan'smunicipal solid management are addressed based on current solutions, short-termsolutions and long-term solutions. These are presented below:. Current solution includes to sort out batteries and mercury tubes, to reconstructcrude dumping into sanitary landfill, to educate residents reducing their wastegeneration, and to make feasibility studies on waste treatment plant.. Short-term solution includes to sort out organic waste, and to install biogas wastetreatment plant.. Long-term solution includes to sort waste in higher degree, to implement theincinerating, composting & landfill approach in extent of region, and to cap thefull filled-up landfill.It is hop ed that this study will orientate further feasibility study on Jingshan'smunicipal solid waste treatment plant and contribute to some extent towards thesolution of the serious municipal solid waste management problems which China isfacing.
Page 51. INTRODUCTIONChina is a rapid developing country with an increasing standard of living. China' sGNP (gross national product) is increasing at approximately 9% per year during thelast 20 years (China Statistical Year 1997). According to the statistic prediction of theChinese SEP A (State Environmental Protection Administration), there will be 700-800 cities and around 20 000 towns in the year 2000, the city population will reach0.45 billion - about 35% of total population of China. The economic development andurban population growth places great stress on urban environment. Municipal solidwaste is one of the many problems re1ated to development. The total annually outputof municipal solid waste generation in China is about 0.11 billion tons in 1996, thisfigure will increase to 0.14 billion tons, 0.85kg/cap/day in 2000 (SEPA, 1998). Incomparison, the waste generation in the u.S in 1995 was to 0.22 billion tons.(DSEPA, 1995).In the recent ten years, waste treatment facilities have increased in great numbers inChina, especially facilities for industrial hazarded waste. Dnfortunately, thesetreatment and management facilities are unable to cope with the increasing growth inthe amount of waste. Landfill is the most common method for handling municipalsolid waste in China. Generally, these landfills do not meet best practices from eithera design or management perspective. Most of them, especially the landfills of smallcities, have scavengers on-site, have no gas controi system, no leachate collectionsystem in place. Even some of municipal solid waste has been causally dumped in thesuburb of cities. The pollution accidents often occurs. The environmental problemsre1ated to waste are becoming worse ( 1. Paul Henderson & Terrill J. Chang, May,1996). Some of most serious environmental problems are addressed as follows:Landfills occupying a great amount of arable land. From 1987 to 1992, the grossloss of arable land in China are 6,556 thousand hectares, about 5.0% of cropland(Lester R. Brown, 1997). Landfill occupying is one of reasons of arable landdecreasing. In some cities, it is nearly impossible to find new dumping sites, hencevaluable arable land are used as landfill.Air pollution in the surrounding of landfills. Most of landfills emit odor, and arebreeding ground of rats and fungus. Landfills also release harmful gases such asammonia (NH4), hydrogen sulfide (H2S) and so on.
