Table 1, the equivalent of using the The 3rd International Conference on Waste

Management and Technology environment factor to describe the life cycle of a list of environmental impact, such as shown in Table 2. In the category of global warming, the environmental impact caused thermal hydrolysis is less than aerobic composting, which is due to the selection of thermal hydrolysis treatment technology, which is based on the solution of hot water technology processing system. The operating system does not directly produce CO2, CH4 and other greenhouse gases. The

follow-up into the composting process also significantly reduced and the amount of natural gas produced will be less. However, aerobic composting technology to the

global warming has brought heavier burden (on the effects of global warming is about 2 times to deal with heat), and this conclusion is reasonable because the high content of organic matter in food waste, compost direct Processing technology, the role of micro-organisms breaking down will produce a great deal of CH4 and CO2 and other greenhouse gases. We can see that impact of processing restaurant garbage with the method of thermal hydrolysis is very small on global warming.

In recent years, air pollution emissions from the clean development mechanism (CDM) point of view, global warming has become more and more important. In a strict sense, since the biological role of the CO2 produced in the process of

biodegradable refuse is the inevitable result of natural processes, some scholars believe that landfill, through the biological role of the CO2 produced without excluding the impact of global warming . At present, the CDM in the area, the conclusions have been widely used in biodegradable garbage and other related

processes. As a result, the establishment of all the carbon is on the basis of biological carbon of restaurant garbage on the basis of assumptions, the CO2 will be divided into biological and fossil kinds. Therefore, the process of composting, including CO2 created in the process of landfill is considered to be from the same biological role. Biological CO2 will be excluded from the category of global warming. In addition, there has been a fundamental impact on the results of change, as shown in Figure 2. Composting is even more obvious than the thermal hydrolysis treatment system for reducing the impact of global warming. The two systems, respectively, account for biological CO2 greenhouse gas emissions 87.9 percent and 68.1 percent. This was mainly due to thermal hydrolysis spending more power and increase greenhouse gas emissions. Therefore, from the viewpoint of CDM, the adverse effects of global warming aerobic composting are no longer significant.
