However green meetings require all the meeting involvers to reduce the consumption of different kinds of resources as well as various materials.
Recycling the rest but still available materials and resources to continue using them.
For example, The Climate Change and Sustainability Global Summit 2013 held in February in New York saved $10,000 by reducing bottle water, $37,000 by using electronic materials and mobile apps instead of paper materials and $20,000 by locating the meeting venue with walk distance from the hotels.

Additionally, β-FeSi2 is made from abundant raw materials and has qualities of innoxious and anti-oxidative.
Therefore, β-FeSi2 is capable of developing thermoelectric materials which work at atmospheric conditions with low-cost and relatively wide temperature scope from 200℃ to 900℃ [1-4].
The raw materials were heated by high-frequency equipment under the protection of Ar atmosphere.

Therefore, it can simulate the fracture and failure process of elasto-brittle-plastic materials such as rock materials.
The two joint materials, as shown in Fig.1, are assumed of the same property, which is shown in table 1 as well as intact rock mass property parameters.
The lower undulation mode leads to completely joint material failure, which performs friction-sliding failure mode.

Greenhouse Effect Reduction Through Sustainable Magnesium Oxide Eco-cement Products Wu Yaoa, Yukun Yangb, Mengxue Wuc Key laboratory of Advanced Civil Engineering Materials (Tongji University), MOE, Shanghai 201804, China ayaowuk@tongji.edu.cn, byangyukuntju@163.com, cwmx_129@163.com Key Words: Eco-cement, CO2 absorption ability, mechanical performance Abstract.
In the process of Portland cement production, there is significant carbon dioxide emission, including the release of carbon dioxide from the conversion of the raw materials, such as limestone, also significant is the fuel combustion to heat the raw materials to 1450°C during the clinkering process.
By incorporating of fly ash into the eco-cement, an energy saving and environmentally friendly material can be formed.
