To prevent and control environmental problems, material and energy’s transfer must be achieved from the economic system to the environment reciprocally and compensatorily, maintained two-way flow of material and energy between the two systems, this is the environmental compensation.
After the material and energy of environment react with pollutants is consumpted excessively, human compensation must be used to restore.

The actual conduct of the environment compensation How to compensate is the center of environmental compensation mechanism, that is a method and process of how to get funds for environmental compensation, how to use the money to buy labor and materials, how to remediate the environment, and restore environmental capacity by certain tools.
Environmental compensation project bidding market is a part of social engineering contracting market, also a part of governmental public works procurement market.

Rheology of blast furnace slags admitted high concentration of titanium oxides Piotr Migas, Marta Korolczuk-Hejnak Department of Ferrous Metallurgy, Faculty of Metals Engineering and Industrial Computer Science, AGH University of Science and Technology, Al.
Due to the prevailing conditions inside, the hearth of the blast furnace is made up of graphite, carbon, carbon-graphite, and microporous materials.
It implies a requirement for adequate quality of refractory materials applied, and as a consequence maintenance costs of such big units necessitate the extension of the life of the furnace.
Charge materials with titanium compounds have started being used in order to extend the life of the refractory lining and the service life of the blast furnace.

Depolymerization of Lignin with Supercritical Fluids: A Review Xing Wanga, Jinghui Zhou*b, Haiming Lic, Guangwei Sund 1Liaoning Provincial Key Laboratory of Pulp and Paper Engineering, Dalian Polytechnic University, Dalian 116034, China.
Lignin as biomass has been long labeled with “waste material”.
The unique properties at supercritical conditions, i.e. strong dependence of the solubility of a material in a super critical fluid to its density and good contact between oxidants and reactants, make SCFs ideal for separation and extraction of useful products and for oxidation of organic materials.
When using different supercritical solvent to process the materials, we can find the reaction of process, the yield, and molecular weight and so on have very big difference.
The mechanistic understanding of the process, the harsh operation environment such as high temperature and high pressure, and its request on the materials and associated cost are the main concerns for its wide application.
