Therefore accelerate to strengthen domestic waste harmless treatment, convert rubbish and make it rise in value, turn waste into wealth, house refuse Recycling, increase social benefit, environmental benefit and economic benefit, imperative.

Chinese MSW research processes and starts late.Various places were according to practical situation in recent years, set about from countermeasure and planning, to city City's technology of garbage disposal has carried out useful exploration.The As-Is that Chinese MSW research processes is: with sanitary landfills and high temperature Composting technology is main, advocates particularly coastal economy developed regions, city with good conditionsi development incineration technology.

The health of water, soil and town dweller is constituted a threat to by municipal refuse, and it is thorny that rubbish has become in urban development Problem.Rubbish air storage, landfill yard landfill not only cause public hazards, the especially huge waste of resource.Waste incineration, although can delay Solve the pressure of municipal refuse, but effective rate of utilization is low, and produce toxic and harmful, slag and dust.Compost treatment, this side Method needs people to separate by organic waste with other rubbish, and sorting difficulty is big, and poor working environment, the benefit of generation is relatively low. Waste incineration and generating electricity, the hypertoxic waste gas that burning produces can not get effectively solving for a long time.

The minimizing of urban and rural domestic refuse, innoxious, resource treatment technique, process cleaning for urban and rural domestic refuse and produce Provide safeguard.Owing to domestic waste containing substantial amounts of Organic substance and petroleum chemicals, so domestic waste carbonization is done Evaporating as the energy is the attractive new forms of energy of one of substitute fossil fuels.Carbide compacting is produced by pyrolysis charring dry distilling Grain charcoal fuel and high-quality blended fuel are the technology that heat chemistry utilizes field.

Use normal pressure continuous high temperature flash carbonization cracking retorting technique, by organic carbon compacting carbon in domestic waste Blended fuel is produced in the cracking dry distilling of granular fuel, petroleum chemicals.Brand-new contiguous processing is provided for domestic waste.
