the seventh eu research framework programme (fp7) environment to provide 1 million 600 thousand euros of funding, the total r & d investment of 2 million 200 thousand euros, the eu 5 member countries (spain, germany, the total coordination) of italy, ireland and cyprus, science and technology joint 6 innovative small and medium sized enterprises (smes) composed of the european eco-cement team. after more than 3 years of effort, we have successfully developed a new low-cost, environment-friendly microbial cement production technology and process.
at present, energy intensive cement production has accounted for 5% of the world greenhouse gas (ghg) emissions, and there is a trend of sustained growth. eu 2020 energy and gas change strategy, mandatory energy intensive industries, including cement production industry, and actively take energy-saving emission reduction initiatives, to develop strict industrial emission reduction standards. the seventh eu research framework programme (fp7) environment to provide 1 million 600 thousand euros of funding, the total r & d investment of 2 million 200 thousand euros, the eu 5 member countries (spain, germany, the total coordination) of italy, ireland and cyprus, science and technology joint 6 innovative small and medium sized enterprises (smes) composed of the european eco-cement team. after more than 3 years of effort, we have successfully developed a new low-cost, environment-friendly microbial cement production technology and process. the joint industrial partners have been selected as part of the eu member countries and are conducting the design, development and pilot demonstration of the production plant.
the r & d team relies on the eu seventh r & d framework plan, scientific and technological achievements "microbial carbonate precipitation technology" (mcp), to determine the low cost, high strength, environment-friendly, the highest principle of the development of biological cement. therefore, the main focus of research and innovation activities in the building or other waste recycling: cement kiln dust or construction waste as calcium source bio cement, a small amount of urea as a catalyst to accelerate biological reaction, the food processing industry or the daily life of the family of organic waste as a nutrient source for microbial bacteria. r & d team by adding a small amount of carbon fiber from the plant, completely solve the strength and life of biological cement problems, so that biological cement fully meet the various functional indicators of traditional cement. r & d team also conducted a comparative study on the efficiency of microbial production of cement bacteria, bacterial spore cultivation considering the difficulty of environmental conditions, adaptive ability and friendly environment and other factors, the final choice of pasteur eight fold (sporosarcina pasteurii bacillus aureus) as the main raw material of cement manufacturing workers "". new technology and products, has successfully passed the expert group of life cycle assessment, and obtain the certificate of eu green products.
compared with the traditional cement, biological cement has been preliminarily estimated, which can effectively reduce the cost of cement production by at least 21%, and reduce energy consumption and greenhouse gas emissions by more than 11%. in addition, the economic and social benefits of building waste recycling and disruptive technology to create jobs have not been counted.
