Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial

The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.

Considering both sides of the blade that first movers have, it will be important for companies to contemplate about conditions that should be met to achieve a success with first mover strategy. There are two conditions. One should know what customers want. One simple way to find out is to ask, “Does this new product have market value?” The idea of the product might have a pote

and society meet a range of energy and environmental challenges.
One example can be found in the area of water use and purification, where GE scientists are investigating new membrane materials and innovative advanced separation technologies. These allow for further treatment and better performance of on-site wastewater reuse and recycling for the industrial, agriculture and municipal sectors.
Ⅲ. Theoretical analysis of the waste problems
We can approach to the analysis of problems to be solved at both a micro and macro level. What we will deal with is the environmental problems taking place all over China, which are characterized by a mix of pervasive influences and a number of factors. It follows that it is more appropriate to take a macro approach which enables us to see problems
2. The Necessity of sustainability
The recent research show that it demands some expenses in the first stage. But when they pass through some point, it will bring the achievements of corporation.
First, the sustainability is a flow in this period that can not be ignored and the essential factor to compete in this field. The playstaion in Sony lost more than 200 million dollars when the Cadmium,
