Domestic biomass waste or plastic materials
Domestic biomass waste or plastic materials
At present, some of China's serious smog problems are attributed to the burning of biomass wastes (such as stalks). The jian-chun jiang said, biomass energy caused by environmental pollution is mainly due to the biomass waste caused by non-standard processing, as long as this part of the biomass waste as raw material in biomass energy industry, scale collection, processing, will not cause environmental pollution, but also can benefit mankind.
In addition to the traditional straw, waste plant and animal oils and fats, with micro algae and duckweed as raw material to the preparation of the key technology of biological liquid fuels in the near future also have the breakthrough, a living material is added momentum of development. Microalgae and duckweed can not only fix carbon dioxide by photosynthesis, but also achieve the purpose of clean water by consuming organic matter, nitrogen and phosphorus in wastewater.
It is known that microalgae is one of the most photosynthetic primitive plants, and the yield per unit area can be tens of times higher than that of crops. Biological science and technology department, tsinghua university professor Chen led the team to overcome the problem of the traditional system of micro algae biodiesel industry, succeeded in producing the high cell density, quick growth, cell oil content of three major characteristics of microalgae, biodiesel production after the test, has good liquidity, high calorific value, low sulphur content three characteristics. These basic studies provide a basis for further development of the microalgae biodiesel industry.
Duckweed is like water hyacinth, proper conditions can grow in the waste water in a large number of plants, if collect processing standardization, scale, not only can produce biomass energy, still can rise to purify the effect. Researcher at the institute of Chinese academy of sciences, chengdu biological zhao hai is introduced, taking duckweed as raw material to the biomass production of traditional biomass raw materials affected by the season can overcome the shortcomings, to achieve the purpose of continuous production throughout the year. In addition, the growth of the duckweed can remove nitrogen and phosphorus in the water, and kill two birds with one stone. Therefore, it is of great significance to develop the floating duckweeds to make bio-liquid fuel from energy balance and environmental protection.
Wu, vice director of China's renewable energy association of gen, said China's current ecological management and ecological environment protection problems highlighted, as a result of biomass energy in unique function of air treatment, waste disposal, etc, as well as the huge potential of industry, so the state should give higher biomass energy industry in recent ten years and more opportunities.
Although the current price slump, because the economy development of biomass energy concerns again, but given that the current our country is in a critical period of governance, to repair the ecological environment, the sustainable development of biomass energy as a clean energy, is still great potential for future development. It was the consensus of experts and scholars at the 7th China international conference on biological quality in Beijing.
China, director of the institute of forestry science research institute of chemical industry in nanjing forest jian-chun jiang believes that the biomass industry development to solve the problem of the ecological environment of the first, then solve the energy problem. China produces more than 600 million tons of straw every year, but the utilization rate of these stalks is not high at present, and it is generally handled through burning pathways, resulting in serious environmental pollution. In the planning of biomass energy development in China, the biomass energy of 110 million tons of coal equivalent is expected to be utilized by 2020. Therefore, the development potential of biomass energy industry in China is huge.
