Msw Dematerialization

In the course of modernization how to deal with the household garbage in urban area (trash for short) is a hard problem that we have to face. It is seems that the trash goes with economic prosperity, produced in astonishing amount and accumulated from year to year. On the contrary, the urban areas are badly short on terminal disposal ability and the disposal cost is rising. This inconsistent phenomenon makes trash accumulation become a basic handicap to the development of a city in the coming future, which means that the social development is unsustainable and it is impossible to maintain or improve the level of social farewell.Beginning with the relationship between the improvement of social farewell and the expenditure of natural resources, this thesis analysis the reason why the urban trash is being produced so fast. The writer doesn't think that the lack of advanced technology is the basic reason for trash's growing and piling up. In social economic system, the trash comes from all kinds of natural resources and the expenditure of natural resources is for the purpose to improve the level of social farewell. If a economy gets its improvement or maintenance of social farewell mainly from increasing the flow of natural resources, the social economic model with intensive materialization is working and the result is a substantial number of trash.The tendency of intensive materialization in the social economic system has close relation with the traditional ideas of natural resources. From the achievement of production function research we can see that people doesn't pay reasonable attention to the action of natural resources in production. This mainly because that in the history, compared with human being's need, we are rich in natural resources. But from now on, it is the limits and lack of natural resources that restrict the improvement of production. This determines that he sustainable improvement of social farewell doesn't come from the increase the flow of natural resources but comes from the improvement of productivity of natural resources. In the same course the growths of trash become lower and lower.The idea of circular economy makes great progress in the disposal of trash but circular economy in every aspect is uneconomic. In the development the circular economy in narrow sense will face great pressure of cost rising. Now the main problem of circular economy in practice is lack of enough benefit drive, and besides, the development of circular economy should towards higher class, that is in the area of production and should not be limited in the lower grade, that is waste collection.Based on the above analysis, this thesis brings forward that the principle of de-materialization should be selected as the strategy of social development. The implementation of the principle of dematerialization means the changing of the ideals of consumption and production, means the changing of living style and reconstruction of industries. The common target of consumption and production is not article but the utility and service carried by the article. So the social economy doesn't get the improvement from increasing the flow of natural resources any longer. And the speed of trash production will go down .Finally, this thesis discusses countermeasures about the disposal of trash. The contents involve the cost research about emergency yards of urban trash, the improvement and calculation of urban recycling ability, levying a tax on enterprises about the disposal of trash, new concept of used material markets and public participation.
