On October 31, the selected Arundo donax test-tube seedlings cultivated by China Resources Cement and Aerospace Shenzhou Biotechnology Group were successfully returned by Shenzhou 16 manned spacecraft through space mutagenesis.
It is reported that in order to innovate and promote the work of energy saving and carbon reduction in enterprises, Huarun Cement has jointly carried out the research and development of basic technologies related to the optimization of biomass fuel crops by space Arundo donax since 2022. The optimal Arundo donax space mutation breeding test-tube seedlings were brought into space by Shenzhou 16 manned spacecraft on May 30 this year. After five months of space travel, it successfully returned to Earth.
The data show that Arundo donax is a kind of perennial plant, which is erect, clustered, with developed root system and tall plant, the plant height is generally 5-8 meters; it has strong adaptability to the environment, is a typical carbon-negative plant, and has a high photosynthetic rate. Space breeding Arundo donax has a strong ability to absorb and fix carbon. During the growth period of space Arundo donax, 4.05 tons of CO can be fixed per mu, which is 30-50% higher than other common biomass fuels.
Moreover, space Arundo donax has another important use-biomass fuel. Space Arundo donax can be used as biomass fuel to replace traditional fossil resources and provide energy for production and life. Studies have shown that space Arundo donax has faster growth rate, stronger plants and higher yield per mu than ordinary Arundo donax. After harvesting, it can be used as alternative fuel through simple processing, and its combustion calorific value is 10-20% higher than that of conventional biomass, and its combustion speed is equivalent to that of bituminous coal.
At present, Huarun Cement has carried out the adaptability planting experiment of space Arundo donax in Tianyang, Guangxi. Planting space Arundo donax in cement mine land can not only realize mine greening, but also absorb carbon dioxide in the air, and can also be used as biomass fuel instead of coal to help cement enterprises achieve energy saving, emission reduction and carbon reduction. It is believed that in the near future, the successful space mutation of Arundo donax test-tube seedlings will bear fruitful results in Huarun Cement Mine-high-quality biomass fuel, and will also open up a new way for the cement industry to reduce carbon!
At present, energy saving and carbon reduction are very important for the cement industry. In addition to the above methods, in recent years, many cement enterprises are also actively exploring the means of energy saving and carbon reduction. Among them, the integration of industrialization and industrialization and the construction of energy management system are gradually popularized in the cement industry as an important way to reduce emissions, improve the level of cement production technology, reduce energy consumption and carbon dioxide emissions.
Relying on digital and intelligent technology, it is urgent to upgrade technology and management and continuously reduce energy consumption, pollutant emissions and carbon emissions. To this end, China Cement Network will hold the "Fifth China Cement Intelligence Summit Forum" in Hangzhou on November 29, 2023 with the theme of "Data-driven Decision-making Intelligence Leads the Future", inviting industry experts, scholars and representatives of relevant enterprises to discuss and promote the intelligent process of the cement industry.
