Believe it or not! Biomass energy will be a breakthrough in solving rural waste

This has to mention biomass energy. Biomass energy is an important renewable energy source, which is directly or indirectly derived from the photosynthesis of green plants and can be converted into solid, liquid and gaseous fuels through physical conversion, chemical conversion, biological conversion and other forms. Its technologies mainly include biomass power generation, bio-liquid fuel, bio-gas, solid molded fuel, bio-based materials and chemicals, etc.

With the increasing emphasis on energy security, ecological environment protection, climate change and other issues, accelerating the development and utilization of biomass energy and other renewable energy has become a general consensus and concerted action by countries around the world. It is also a major strategic move to address climate change. However, most of the waste in rural areas has not been effectively used, which not only causes serious pollution to water, soil, air pollution, etc., but also consumes a lot of manpower, material and financial resources during processing. Based on the premise of resource utilization, it is necessary to find suitable new solutions. Methods and new ways out are imperative.

According to data, in addition to being used as feed and industrial raw materials, most of the more than 500 million tons of available crop straw can also be used as cooking and heating fuel for farmers. Currently, rural areas across the country are used as energy sources. China's straw consumption is about 300 million tons; while my country's total livestock manure resources are about 900 million tons, equivalent to nearly 80 million tons of standard coal. It is conceivable that if these wastes are utilized as resources, better ecological and social benefits will be achieved while reducing treatment costs.

Of course, policy support is also indispensable. In July 2019, the National Energy Administration issued a letter soliciting opinions on the "Notice on Solving Relevant Issues in the Promotion of Clean Heating such as "Coal to Gas" and "Coal to Electricity", which addressed the environmental problems caused by the direct combustion of large amounts of agricultural and forestry waste. A corresponding solution was put forward - focus on the development of biomass heating, and encourage rural areas to actively explore clean heating channels if they have resource conditions and financial strength.

How to make good use of these biomass energy? Zhao Lixin, deputy director of the Planning and Design Institute of the Ministry of Agriculture and Rural Affairs, pointed out that it is better to adjust measures to local conditions. Each place has different natural resources and resource endowments. It will be better to have different energy ratios based on its actual conditions. The second thing to pay attention to is which technical model to choose, and the economics and technical applicability of the technology should be considered. This means that we need to take into account the scale and type of rural resources, and at the same timeAt the same time, it is necessary to actively participate in and support the use of biomass energy within the acceptable range of farmers. If it exceeds the economic level and actual scale requirements of the region, not only the operation effect cannot be guaranteed, but also the consequences of idle facilities and equipment.

It should also be noted that the promotion of biomass energy in rural areas is a one-time investment. When it reaches a certain scale and is industrialized, the investment will come down. After it is started, there will be almost no cost, and it will form recyclable, safe and clean heating and power generation. Taken together, vigorously developing the biomass energy industry is of great significance for completing the tasks of energy supply and blue sky defense.
