Biomass briquette fuel (weekly topic)

The first is the policy issue. All forms of energy have their own advantages and disadvantages, and biomass energy is no exception. While it boasts advantages such as large reserves, renewability, and low pollution levels, it also has drawbacks including a long industrialization cycle – for example, it takes 5 to 6 years for woody energy crops to reach maturity, and it takes over a decade to develop superior varieties. As a result, short-term benefits cannot be achieved, and there is insufficient support for the development of the biomass energy industry in various aspects. Furthermore, due to insufficient understanding of this new energy technology and a weak foundation, some of the goals set were somewhat overly ambitious. 　The second is the technical issue. Currently, most of the biomass energy technologies in our country are stand-alone technologies; whether it is pelletized fuel, gasification technologies, or fuel ethanol and biodiesel, these various technologies operate independently of one another, with a lack of integration between them. 　Third is the issue of raw materials. The development of biomass energy in our country has followed the trend of relying primarily on agricultural and forestry waste such as crop straws. However, crop straws are highly affected by seasonal factors, which leads to problems such as insufficient raw material supply and poor sustainability in the development of the biomass energy industry.

Biomass energy is solar energy fixed on Earth through plant photosynthesis, and it is most likely to become one of the main new energy sources in the 21st century. It is estimated that the energy stored by plants each year is roughly 10 times that of the world’s major fuel consumption ； Meanwhile, the amount utilized as energy is less than 1% of the total. Most of this unutilized biomass releases its energy and carbon back into nature through natural decomposition, in order to complete the carbon cycle in the environment. In fact, biomass energy is the earliest, most widely used, and most direct form of energy utilized by humans. To this day, more than 1.5 billion people around the world rely on biomass as their source of energy for daily life. Biomass combustion is a traditional method of utilization; it not only has low thermal efficiency, but also involves heavy labor intensity and causes serious pollution. Through biomass energy conversion technologies, biomass energy can be utilized efficiently to produce various clean fuels, replacing fuels such as coal, oil, and natural gas, as well as to generate electricity. It also reduces dependence on fossil fuels, protects **energy resources, and mitigates the environmental pollution caused by energy consumption. Experts believe that biomass energy will become an important component of future sustainable energy sources; by 2015, 40% of the world’s total energy consumption will come from biomass energy. 1.2 Energy and Environment: Humanity is facing dual pressures from development and the environment. The development of the economy and society relies heavily on energy as a driving force. The more the economy develops, the greater the energy consumption, particularly the increase in fossil fuel use. This presents two major problems: first, it leads to increasingly severe environmental pollution; second, the existing reserves of fossil fuels on Earth will eventually be exhausted. Based on consumption levels, the world’s oil resources will eventually be exhausted over the next 50 to 80 years. By 2059, the 200th anniversary of the drilling of the world’s first oil well, there will likely be very few remaining oil resources in the world. On the other hand, excessive consumption of fossil fuels leads to the rapid and premature depletion of these limited resources, resulting in the release of large amounts of excess energy and carbon. This disrupts the natural balance of energy and carbon, and is a direct cause of catastrophic consequences such as ozone layer depletion, global warming, and acid rain. In other words, if no new energy sources are developed to replace fossil fuels as the dominant force in the energy structure, severe and catastrophic energy and environmental crises will inevitably occur in the 21st century, representing one of the three most likely disasters that humanity will face in the coming century. 1.3** Safety. Of course, developing biomass energy is not the only way to obtain new sources of energy; humans can use advanced technologies to get nuclear energy, or even source energy from outer space. Yet the hazards associated with these methods are obvious to all. Firstly, the development of nuclear energy is highly likely to introduce new sources of instability into an already unstable world, and may even directly threaten the human living environment ； Secondly, energy development in the limited outer space areas that various countries or groups can reach with the technological level of the next century will inevitably give rise to new conflicts or disputes, the consequences of which are self-evident. Biomass energy is not only the safest and most stable form of energy, but it can also be used to produce various types of energy through a range of conversion techniques: solidification and carbonization can yield solid fuels, gasification can produce gaseous fuels, liquefaction and extraction of vegetable oils can result in liquid fuels, and electricity can also be generated if necessary. Currently, countries around the world, especially developed countries, are striving to develop efficient and pollution-free technologies for utilizing biomass energy. This effort aims to conserve their own mineral energy resources and provide a fundamental guarantee for the sustainable development of their economies. 2. Development status of biomass energy technologies abroad. The development and utilization of biomass energy have long attracted the attention of governments and scientists around the world. Many ** have formulated corresponding development and research plans; examples include Japan’s Sunshine Project, India’s Green Energy Mission, the United States’ Energy Farms, and Brazil’s Alcohol Energy Program. Other countries such as Denmark, the Netherlands, Germany, France, Canada, and Finland have been carrying out their own research and development over the years, establishing unique systems for the research and development of biomass energy and possessing their own technical advantages. 2.1 Biogas technology mainly involves the anaerobic treatment of livestock manure and high-concentration organic wastewater; it is a biomass energy utilization technique that was developed quite early on. Before the 1980s, in developing countries, **biogas digester technology was primarily developed to produce biogas from agricultural crop residues and livestock manure, which was then used as fuel for cooking. Such as household biogas digesters in India and China ； Developed countries, on the other hand, mainly develop anaerobic technologies to treat livestock manure and high-concentration organic wastewater. At present, developed countries such as Japan, Denmark, the Netherlands, Germany, France, and the United States generally use anaerobic methods to treat livestock manure, while developing countries like India, the Philippines, and Thailand have also established large-scale biogas projects as demonstration sites for the treatment of livestock manure. Adopt a new self-circulating anaerobic technology. The Dutch IC company has managed to achieve a gas production rate of 10 m³/m³·d in the anaerobic treatment of brewery wastewater, thereby **saving on investment, operating costs, and land area**. In developed countries such as the United States, the United Kingdom, and Italy, biogas technology is primarily used for waste treatment. In New York, USA, the Staten Island Waste Management Facility invested $20 million to implement a wet processing method for waste treatment. This facility produces 260,000 m³ of biogas per day, which is utilized for power generation and fertilizer recovery. The economic benefits are considerable; it is expected that the entire investment will be recouped within 10 years. The UK generates 18 MW of power from biogas produced from waste, and it will invest another 150 million pounds over the next 10 years to build more waste-to-biogas power plants. 2.2 Biomass pyrolysis gasification As early as the 1970s, some developed countries such as the United States, Japan, Canada, and the countries of the European Community began research and development on biomass pyrolysis gasification technology. By the 1980s, 19 companies and research institutions in the United States were engaged in such research and development ； Laboratories at 12 universities in Canada are conducting research on biomass pyrolysis gasification technology ； In addition, developing countries such as the Philippines, Malaysia, India, and Indonesia have also carried out research in this area. Tampere Power Company of Finland has begun constructing a biomass gasification power plant in Sweden, with a capacity of 60 MW for electricity generation and 65 MW for heat production; the plant is scheduled to become operational in 1996. The Swedish Energy Centre has secured a loan from the World Bank to build a power plant in Brazil with a capacity of 20–30 MW. This plant will utilize advanced technologies such as biomass gasification and combined cycle power generation to process the region’s abundant sugarcane bagasse resources. 2.3 Biomass liquid fuels Another technology of interest is biomass liquid fuels, including ethanol and vegetable oils, which can be used as clean fuels to directly replace petroleum-based fuels such as gasoline. Brazil is the country with the most distinctive development and application of ethanol fuel. In the mid-1970s, in order to reduce its excessive dependence on imported oil, it launched the world’s largest ethanol development program. By 1991, ethanol production had reached 13 billion liters. Among the 9.8 million vehicles in Brazil, nearly 4 million were powered solely by ethanol; the vast majority of the remaining vehicles used a gasoline-ethanol mixture containing 20% ethanol. In other words, ethanol fuel accounted for over 50% of all automotive fuel consumption. In 1996, the U.S. Renewable Resources Laboratory developed a technology for producing alcohol from cellulose waste. The Husco Industrial Group in the United States established a 1MW rice husk power generation demonstration plant: it processes 12,000 tons of rice husks per year, generates 8 million kWh of electricity annually, and produces 2,500 tons of alcohol per year, achieving significant economic benefits. 2.4 Other technologies Additionally, biomass compression technology can be used to compress solid agricultural and forestry waste into compacted fuel that can serve as a substitute for coal. For example, the United States developed biomass pelletized fuel; third-world countries such as Thailand, the Philippines, and Malaysia have developed rod-shaped pelletized fuel. 3. Biomass energy in our country: Our country is primarily an agricultural nation, with the rural population accounting for over 70% of the total population. Biomass has always been one of the main sources of energy in rural areas, and it also holds an important position in the overall energy structure. 3.1 Biomass energy resources: China currently has 4.14 billion hectares of forest, grassland, and arable land. Theoretically, the biomass resources could reach 65 billion tons per year (on average, plants produce approximately 158 tons of organic carbon per square kilometer each year through photosynthesis). Based on an average calorific value of 15,000 kJ/kg, this translates to a theoretical resource amount of up to 3.3 billion standard tons of coal, which is more than three times China’s current annual total energy consumption. In reality, the biomass that can be used as an energy source currently includes straw, firewood, livestock manure, household waste, as well as organic waste and wastewater. According to surveys, the amount of straw resources in our country currently exceeds 720 million tons, equivalent to about 360 million tons of standard coal. Of this amount, around 120 million tons are used for purposes such as feed, paper production, textiles, and construction materials, while the remaining 600 million tons can be utilized as energy. The main sources of firewood include forestry harvests, pruning for forest management, and fuel forests. One survey indicates that China’s annual firewood production is around 127 million tons, which is equivalent to 74 million tons of standard coal. The amount of manure from livestock and poultry is equivalent to about 130 million tons of standard coal ； The amount of urban waste generated is around 120 million tons, with a growth rate of 8%-10% per year. It is estimated that the total amount of biomass energy resources available for utilization in China amounts to about 700 million tons of standard coal. 3.2 Biomass Energy and Its Utilization In China, the majority of biomass energy is used for rural household energy needs, with only a small portion being utilized in the industrial production of township enterprises. For a long time, the primary method of utilizing biomass has been direct combustion; it is only in recent years that new technologies for utilizing biomass energy have been adopted, though on a limited scale. Its adoption is low; it accounts for an extremely small proportion in the energy mix of **, even in rural areas. The direct combustion of biomass not only has low thermal efficiency, but the large amounts of smoke and ash emitted also deteriorate people’s living environments, severely harming the physical and mental health of women and children. Furthermore, it also has extremely adverse effects on the ecosystem, society, and economy: 1. When biomass energy must be used but in an improper manner, it inevitably leads to excessive logging of natural resources such as forests, thereby destroying natural vegetation and ecological balance ； 2. Resources such as organic waste, organic wastewater, organic residues, livestock manure, and certain agricultural wastes are not being fully utilized, which not only leads to resource waste but also turns them into major sources of organic pollution. In addition to causing severe air and water pollution, these substances emit large amounts of greenhouse gases, exacerbating the global greenhouse effect ； 3. At the same time, with the rapid economic development and the improvement of people’s living standards, energy shortages will inevitably become a major obstacle to the sustainable economic development in the 21st century. This issue requires sufficient attention, and effective measures must be taken to address it. In fact, the vigorous development and utilization of biomass energy are of great significance for alleviating the energy, environmental, and ecological problems of the 21st century, bringing numerous benefits ； 4. Reduce pollution and improve people’s living conditions. Whether it is the treatment of organic wastewater, the utilization of municipal waste as an energy source, or the pyrolysis of straw, an important common goal in all these cases is to address environmental pollution issues; this is also the primary objective of most biomass utilization efforts. 5. Solve the problem of rural energy supply and improve the living standards of farmers. In China, the energy supply in rural areas is tight, while biomass resources are abundant. Therefore, the utilization of biomass energy can be promoted to improve the energy supply in rural regions. Improve their standard of living. 6. Improve the energy structure to reduce environmental pressure. China has 700 million tons of exploitable biological resources. If fully utilized, these resources could play a significant role in the country’s energy consumption. This is of great importance for improving China’s energy structure, reducing its dependence on fossil fuels, and consequently cutting down emissions of pollutants such as CO2 and SO2. Ultimately, this helps alleviate the environmental pressure caused by energy consumption. 3.3 Market Demand It can be predicted that, with the development of the national economy and the improvement of people’s living standards, the market prospects for biomass energy utilization technologies and devices will become increasingly broad. Main basis: 1. Currently, the vast majority of crop straws are burned in fields without being put to effective use. This not only results in a huge waste of energy, but also causes serious environmental pollution, having a certain negative impact on social life and economic development. Such as the dust incidents that occurred at Chengdu Shuangliu Airport and Capital Airport. As farmers become increasingly wealthy and their standard of living improves, there is a pressing need to change the current practice of using straw and firewood directly for cooking and heating. By adopting biomass fuels as their energy source, they can improve their living conditions, enhance their quality of life, and reduce the physical strain associated with these tasks. 2. Numerous factories that process grains, timber, tea, fruits, and other products generate large amounts of waste such as grain husks, sawdust, wood chips, and fruit peels on a daily basis. By using biomass gasification technology to convert these wastes into combustible gases, high-quality energy can be produced, turning waste into treasure and achieving two benefits at once. 3. Poultry and livestock manure is both a source of severe environmental pollution and an important source of biomass energy; as large-scale farms continue to be built and developed, the environmental pollution they cause is becoming increasingly serious. Using anaerobic technology to treat livestock and poultry manure holds dual significance for both energy and the environment. 4. With the rapid development of China’s social economy, the increase in urban population, and the improvement of residents’ living standards, the issue of urban waste disposal has become increasingly prominent. Taking Beijing in our country as an example, in 1995 the annual waste generation volume exceeded 4 million tons, and in 1996 it reached 4.85 million tons in Beijing. Using anaerobic technology to treat organic waste not only generates energy but also enables pollution control at low costs. 5. In China’s remote areas, biomass resources are abundant; these regions often suffer from electricity shortages or limited power supply. Biomass gasification can be used to generate electricity or provide heat for local use. 6. In fact, the reason why biomass energy technologies have broad market prospects is that their advantages lie in the fact that developing and utilizing biomass energy not only provides an inexhaustible source of energy, but also helps protect the environment and conserve resources. 3.4 Current Status and Challenges in the Development of Biomass Energy Technology in China The Chinese government and relevant departments attach great importance to the utilization of biomass energy; several top leaders have issued multiple directives emphasizing the need to enhance the use of crop straws as an energy source. **The Science and Technology Commission has, for three consecutive **Five-Year Plans**, designated the research and application of biomass energy technologies as key research projects. This has led to the emergence of numerous outstanding scientific achievements and successful application examples, such as biogas digesters, biogas technology utilizing livestock and poultry manure, biomass gasification for power generation and centralized gas supply, and biomass briquettes. These efforts have yielded considerable social and economic benefits. At the same time, our country has developed a high-level team of researchers, including renowned domestic research institutions and universities; it boasts a group of distinguished experts and scholars who are dedicated to the research and development of biomass pyrolysis and gasification technologies. a. Biogas technology is the biomass energy utilization technology that was developed earliest in our country and was once widely promoted for industrial use. In the 1970s, to address the shortage of rural energy, China made great efforts to develop and promote household biogas technology; as a result, 5.25 million household biogas digesters were built nationwide. In the past three consecutive five-year plans, **developing new biogas technologies has been listed as a key scientific and technological priority, with a large number of research projects and demonstration projects related to biogas and its utilization being carried out. To date, our country has built more than 30,000 large and medium-sized biogas digesters, with a total capacity of over 1.37 million cubic meters. The annual production of biogas amounts to 55 million cubic meters. There are more than 630 biogas projects with a capacity of 100 cubic meters or more; of these, 583 are centralized gas supply stations serving 83,000 households. The average annual gas consumption per household is 431 cubic meters, and this gas is mainly used for treating livestock manure and organic wastewater. These projects have achieved certain environmental and social benefits, playing a positive role in developing the local economy as well as China’s anaerobic technology. Under the Ninth Five-Year Plan, high-efficiency anaerobic technologies for treating high-concentration organic wastewater and municipal solid waste were designated as key projects for scientific and technological research. These projects are being carried out by the Chengdu Institute of Biology of the Chinese Academy of Sciences and the Hangzhou Institute of Energy and Environment, respectively, and have now made the expected progress. The main problems in anaerobic technology and engineering in our country include limited research on related technologies, poor compatibility of auxiliary equipment, low level of automation, rough fabrication of custom-made equipment, high project costs, and severe secondary pollution from open-type pre- and post-treatment processes. b. Biomass gasification technology in our country has seen significant progress in recent years. The types of gasifiers have evolved from traditional suction and downward suction types to the most advanced fluidized bed, rapid fluidized bed, and dual-bed systems. Besides traditional heating applications, the main breakthroughs lie in providing gas supply to rural households and using gasification for power generation. “During the Eighth Five-Year Plan period, the **Science and Technology Commission assigned a research project focused on \"biomass pyrolysis, gasification, and heat utilization technologies,\" and considerable results were achieved: by using an oxygen-based gasification process, a gasification device capable of extracting the calorific value from biomass was developed ； Using the above suction-type fluidized bed process, 100 biomass gasification centralized gas supply systems and devices were developed; using the above suction-type fixed-bed process, biomass gasification and drying systems and devices for food and cash crops were developed ； A 1,000-household biomass gasification centralized gas supply system and equipment have been developed using the fluidized bed dry distillation process. “During the Ninth Five-Year Plan period, the **Science and Technology Commission assigned a special research project on \"biomass pyrolysis and gasification and related technologies,\" focusing on the development of 1MW large-scale biomass gasification power generation technology as well as centralized gas supply technology for rural straw gasification. To date, nearly 200 rural gasification stations have been built across the country, along with over 100 sets of gasification power generation units; the impact of gasification technology is gradually expanding. c. During the Eighth Five-Year Plan period, China began exploring and researching technologies for producing ethanol fuel from cellulose waste, focusing mainly on the dilute acid hydrolysis of such waste along with fermentation techniques; during the Ninth Five-Year Plan period, these efforts entered the pilot test stage. Our country has conducted preliminary research on alternative fuels such as vegetable oils and biomass pyrolysis oils: initial experimental studies have been carried out on aspects such as the physicochemical properties of vegetable oils, esterification modification processes, and their combustion performance in diesel engines. “During the Ninth Five-Year Plan period, taxonomic surveys of wild oil plants were conducted, as well as the establishment of breeding bases. There is also some research on biomass liquefaction in our country, but the technology is relatively backward, with research mainly focused on high-pressure liquefaction and pyrolytic liquefaction. d. In addition, during the Eighth Five-Year Plan period, China also focused on advancing scientific and technological research in biomass compression molding technology. By introducing advanced foreign models and adapting them to local conditions, various types of biomass compression molding machines suitable for China’s circumstances were developed, which are used to produce rod-shaped, lump-shaped, or granular biomass fuel. The service life of the screws in China’s biomass spiral formers exceeds 500 hours, which is at an internationally advanced level. Although our country has achieved great success in the development of biomass energy, there is still a certain gap in technical level compared to developed countries; for example: a. The development of new technologies is inadequate, and the utilization techniques are limited. In the early days, biomass utilization in our country was mainly focused on biogas production. In recent years, more attention has been paid to the development and application of pyrolysis and gasification technologies, and certain advancements have been achieved; however, progress in other technologies has been very slow. There have been no breakthroughs in areas such as alcohol production, pyrolytic liquefaction, industrial direct combustion technologies, or the cultivation of fast-growing forests. b. Due to scattered resources and outdated collection methods, the scale of biomass energy utilization projects in our country is very small ； To reduce costs, most projects employ simple processes and basic equipment, resulting in low equipment utilization and poor conversion efficiency. Therefore, biomass energy projects have low return on investment and high operating costs, making it difficult to achieve economies of scale, and they fail to play their intended and significant role as a source of energy. c. Compared to the research requirements, insufficient investment has led to a low level of technical sophistication in the research; it mostly involves low-quality repetitive studies, and as a result, key issues such as low gas production rates in anaerobic digestion and poor levels of automation in equipment and management have not been resolved ； The issue of tar in gasification utilization has not been fully resolved, posing serious problems for long-term use ； Biogas power generation and gasification power generation have low efficiency, and the associated problems of secondary pollution have not been fully resolved. This causes many engineering systems to be frequently in a state of maintenance or malfunction, thereby reducing their operational capacity and efficiency. Furthermore, in the actual socio-economic environment of our country, there are also some negative factors that restrict or hinder the development, dissemination, and application of biomass energy utilization technologies. These factors are mainly as follows: a. Under the current energy price conditions, biomass energy products lack market competitiveness; low return on investment deters investors from making such investments, while high sales prices discourage consumers. b. Technical standards are not standardized, and market management is chaotic. In the development of straw gasification for gas supply and biogas projects, the lack of appropriate technical standards and strict technical oversight has led to many entities and individuals without the necessary technical expertise taking on the task of contracting such projects or producing equipment for straw gasification. As a result, the quality of these projects is inadequate, they fail to meet their intended goals, and safety issues may even arise. This has a significant negative impact on future efforts to utilize biomass. c. At present, the policies aimed at supporting the development of biomass energy lack practicality; authorities at all levels should promptly establish relevant policies, such as price subsidies and other special incentives for power generation and grid connection. d. The public lacks sufficient awareness of biomass energy; efforts should be intensified to promote and disseminate relevant knowledge. e. **Sufficient attention should be paid to the strategic importance of biomass energy; developing biomass energy is a systematic project that should be regarded as a fundamental infrastructure effort for achieving sustainable development.** 4. Development Directions and Countermeasures 4.1 Development Directions China is rich in biomass energy resources, and these resources are inexpensive; moreover, the economic environment and level of development are favorable for the advancement of biomass technology. Based on these characteristics, the development of biomass in our country needs to draw on advanced foreign experiences while also emphasizing its own unique features. Therefore, the future direction of development should focus on the following areas: a. Further leveraging the role of biomass energy as a supplementary source of energy in rural areas, providing clean energy there to improve the living environment and standards of life for the rural population. This includes practical technologies such as biogas utilization, straw gasification for fuel supply, and small-scale gasification power generation. b. Strengthen the industrial application of biomass, increase the proportion of biomass energy utilization, and enhance the role of biomass energy in the energy sector. Only in this way can the impact of biomass energy be significantly increased, creating the conditions for its large-scale use in the future; it is also the key to whether biomass energy can become an important alternative energy source in the years to come. c. Technologies for converting biomass into high-quality energy products, to enhance the utility value of biomass energy. This is an important technical foundation, the basis for utilizing biomass through various means in the future, and key to enhancing the role and significance of bioenergy. d. At the same time, utilize mountainous areas, wastelands, and deserts to develop new biomass energy resources; research, cultivate, and develop fast-growing, high-yield plant varieties. In areas where conditions permit, establish energy farms and forestry estates to create biomass energy bases that can supply large-scale amounts of energy resources such as wood or vegetable oil. 4.2 Countermeasures Based on the main development directions outlined above, whether biomass utilization technology in our country can develop rapidly in the future depends primarily on the following aspects: a. In terms of industrialization: it is necessary to strengthen the commercialization of biomass utilization technologies, establish strict technical standards, enhance technical supervision and market management, and regulate market activities in order to create a favorable market environment for the promotion of biomass technologies. b. In terms of industrial production and large-scale application: strengthen the link between biomass technology and industrial production, and address key technical challenges through demonstration projects. In terms of technical research: focus on resolving the technical problems that arise during dissemination and application, while improving and testing the reliability and cost-effectiveness of biomass energy technologies in practical production, thereby creating conditions for the large-scale use of biomass. c. In terms of technical research: it is necessary to focus on resolving the technical challenges that arise during implementation and dissemination, such as tar treatment and biogas technologies for cold regions, while simultaneously exploring new technologies for biomass utilization, including research on advanced methods such as converting biomass into oil and oxygen. d. Formulate a **development plan for biomass energy**, introduce new technologies and processes, carry out demonstrations, development, and dissemination, in order to make full and rational use of biomass energy resources. In the 21st century, high-quality biomass energy products (in the forms of solid fuels, liquid fuels, gaseous fuels, etc.) will gradually replace some mineral fuels in order to address issues such as energy shortages and environmental pollution in our country. 4.3 Priority Areas .

Reply 1# Standing in the East

Overall, it’s still in its initial stages

Reply to 1#: From an Eastern perspective, it seems that not enough emphasis is placed on this area; there isn’t sufficient focus on it. For example, before 2007, there were few projects related to polysilicon, but after 2008, such projects appeared everywhere across the country. When there is a large profit margin, both technology and business practices improve accordingly. I really don’t know much about technology aspects; I haven’t delved into them much
