Making pellets from agricultural waste
Our aim is to turn all agricultural waste into bio-pellets and to produce a variety of biofuels. The industry-leading energy technology company is currently conducting trials on the "production of fuel pellets in a fermentation process", developing a combustion technology for the production of biomass fuel pellets. It is hoped that this technology can be used to produce a truly high quality and clean energy source.

The company is developing a biomass fuel that is made up of agricultural waste and plant and animal manure which, after a certain period of time, will be turned into pellets that will be sent to a plant for secondary combustion.
This is a new technology: they simply need to be mixed with coal and burned. The company is also working on how to use this technology in order that this biomass fuel does not break down into carbon dioxide (CO2). It is hoped that this technology will receive more support, especially in the case of biomass fuel pellets. This biomass fuel can be used to burn all fuels, such as coal tar and natural gas.

Currently these biomass fuels are considered to be very expensive, uncompetitive rubbish and waste. However, more benefits can be gained if agricultural waste is converted into bio-pellets. By making these pellets we can use them as biofuel for crop straw or other agricultural crops. They can also be used to collect waste from farms, such as feed waste, and reprocess it to make liquid feed. We want to achieve the conversion of all agricultural waste into bio-pellets and produce clean energy.
Biomass pellets made from bamboo
Biomass pellets are a very valuable renewable resource. With an ageing population and an increasing demand for energy, biomass pellets can be produced from existing raw materials as an energy source. Currently biomass pellets are well used in agriculture, industry and transportation.

Using bamboo as a raw material to manufacture biomass pellets is a viable way to solve the problem of environmental pollution caused by the massive accumulation of agricultural and forestry waste in rural areas. And from a worldwide perspective, large-scale, clean wood products and industrial biomass raw materials are widely used in household, food, packaging and other fields.

In response to the scarcity and high price of lignocellulosic raw materials, we are well placed to establish a technological pathway that can make full use of biomass materials such as bamboo for the production of energy biomass pellets. After processing bamboo fibers into lignocellulosic pellets, the resulting biomass pellets can be used as a cooking and fuel source (e.g. biogas), or as a transport and construction material.

This is a clean energy source that not only saves a lot of water but also reduces the formation of greenhouse gases such as carbon dioxide. It is also beneficial for wood processing and industrial utilization of waste materials such as high-density and highly reactive foams, bamboo charcoal-based environmental fuels, etc.
Straw as raw material for granulation
Biomass fuel refers to waste such as crop straw, weeds and leaves, which are processed and transformed into biomass fuel. It has the advantages of being environmentally friendly, energy efficient, highly effective and renewable, and is known as a renewable energy source. It is a sustainable and clean energy source that will provide a new option for environmental protection.

According to the journal Science, researchers at Ohio State University and other institutions in the US have developed a new bioengineering technology - biomass pellet technology. The technology uses plant straw as raw material, and the bio-pellets obtained after a series of processing processes such as crushing and grinding are directly used to produce clean energy. The pellets can be used as pellet fuel in domestic hot water boilers or industrial boilers.

Researchers say the technology could be used to replace the hydrocarbons and sulphury compounds in fossil fuels, reducing greenhouse gas emissions. At the same time, the biomass pellet fuel does not pollute or pose a threat to the environment and could provide significant energy savings to the global energy system in order to achieve low carbon development.
Pelletizing biomass pellets from sawdust
This is a new biomass manufacturing technology that will be the future direction of the biomass energy industry. Currently there are various forms of energy used to manufacture biomass in the world, including coal, oil and natural gas, but most of them are non-renewable resources.

According to statistics, China alone produces about 12 million tons of various types of waste each year, including various types of wood, crop straw, industrial waste and other biomass. Among them, sawdust accounts for 80-90%. And sawdust production of bio-pellets mainly uses sawdust and biomass (including rubbish) to produce bio-fuel, and sawdust utilization has become a trend worldwide. This has also led to difficulties in recycling sawdust and biomass raw materials, which has restricted the development of the biomass energy industry and even led to ecological and environmental problems brought about by the energy surplus.
Biomass resources are one of the country's most important strategic energy resources, and there are still a large number of enterprises producing biomass pellets from charcoal, sawdust and other raw materials. Due to the tight wood resources, the large production of wood chips and low prices, low costs and other reasons caused sawdust cannot be recycled.

At present Russia, Turkey and Kazakhstan are respectively one of the main wood chip producing countries in the world. Therefore, the development and industrialization of these technologies will greatly contribute to the healthy development of the biomass energy industry and environmental protection in each country. This is currently the only international technological route that makes full use of sawdust and allows for its recycling.
Manufacturing of biomass pellets from peanuts
The journal Nature has recently published the latest research results from China, in which a new technology entitled "Manufacturing energy pellets from peanuts as biomass feedstock" has made a new breakthrough in the conversion and utilization of biomass resources.

The project was jointly completed by Dalian Institute of Chemical Engineering, Chinese Academy of Sciences, Institute of Biophysics, Zhejiang University and other units, and was funded by the National Natural Science Foundation of China. The person in charge said: "Peanut as a raw material to manufacture bio-pellet is currently a relatively mature technology in the biomass industry, and is also the world's largest production of high value-added energy products. We hope that this technology can be extended to other biomass fields."

According to the report, peanuts, an important component of biomass, can be used to produce biomass and energy from pellets that are about 10mm to 20mm in diameter; they can produce large amounts of carbon dioxide and water during combustion and are one of the low energy sources.

The researchers say that this technology will be developed in the future as a new generation of biomass energy. For now, the project is just an idea. They say that the business model of combining biopower and biomass feedstock processing through technological innovation will also be gradually realized in the future. And in order to achieve this goal, they hope to also find large biomass pellet plants or companies suitable for commercial processing to collaborate with in the future.
Rice husk as raw material for pelletizing
The rapid development of the new energy vehicle industry is inseparable from the widespread use of biomass fuels. Recently, some enterprises and government departments announced plans to solve the environmental pollution problems in biomass fuel production and promote the development of the new energy vehicle industry by using biomass fuel to produce biomass pellets. The straw is the core material for new energy vehicles.

Technically speaking, rice straw produces methane, carbon monoxide, nitrogen oxides and other harmful gases and particulate matter during the combustion process. The traditional process produces a large number of toxic and harmful gases and chemical pollutants such as particulate matter, as well as causing secondary pollution to the rice husk. And the technology uses rice husk to produce biomass pellets, which can effectively solve the above problems.

Rice husk has been widely used internationally as a biomass feedstock, but as rice husk cannot be burned directly, there are problems such as inadequate combustion and secondary pollution to the environment. The process is currently being further improved and the raw material is being dried after 3-4 days to form a product that is used in the automotive manufacturing sector.

And it is understood that, with the traditional practice of manufacturing biomass pellets from straw as raw material is different, the enterprise will use energy efficient technology and other ways to achieve the development of new energy vehicle industrialization to support and help.
Making Biomass Pellets
Biomass pellets are made from biomass, which can be burned directly or as fuel. Compared with other renewable raw materials such as traditional wood, rice husk and wood chips, biomass pellets have the advantages of less carbon and no harmful substances. Biomass pellets can be used as a fuel or as a fuel for power generation.

With the development of biomass fuel technology, the fluctuation of biomass energy prices, climate change and other factors leading to increasing fuel costs, new biomass gas pellets as a new fuel is receiving widespread attention.
Biomass fuels are made from crops such as rice husk, wheat straw, wood flour, corn cobs, grass clippings, cotton seed husk and other crops that are processed into various types of fuels such as biomass pellet fuels (e.g. biomass pellet fuels, gasification fuels and chemical fuels, etc.).

It is understood that traditional fuels (e.g. straw fuel, LPG fuel, methanol fuel, etc.) contain elements such as sulphur, nitrogen and oxygen. Natural gas fuels (e.g. liquefied petroleum gas (LPG), liquefied petroleum gas (CNG), shale gas) contain elements such as sulphur and oxygen. Oil and gas contain more carbon components and have an odour.

In contrast, biomass pellets are a new type of fuel with great development value. However, at present only a few large companies have mastered the technology.
Vertical pellet mill
The Vertical pellet mill is a kind of energy-saving and green machinery which can be used in a renewable way. Its invention breaks the traditional technology of corn threshing machinery and many high technologies are applied in this project.

The crushed pellets are pre-crushed and compressed before being thermalised. Its greatly reduces the temperature loss of the equipment, improves the cooling effect of the equipment, increases the crushing efficiency and the crushed granules have better mechanical properties.

In addition, according to the characteristics of this model, the principle of vacuum hot air circulation heating mechanism is used. The equipment produces high temperature gas for hot air circulation during operation, while the heat source of the heating mechanism operating device uses water steam and water for heat exchange to achieve continuous heating mode without generating any heat. The whole machine is mainly composed of a fan, a feed pump and a feed drum.

The hot air circulation heater is able to circulate burning natural gas or other hot air through the feed pipe. The hot medium enters the hot air circulation and causes the air in the drying chamber to expand strongly, making the granules rapidly expand, form and have better toughness and less breakage, while the granules can be further compressed and cooled after forming. The hot medium consists mainly of the steam supply system, the feeding system and the feeder group. The hot media can also be used for conveying and storage under non-heat heating conditions.

Due to its compact structure, easy installation and replacement as well as fuel saving advantages, it is widely adaptable to materials and suitable for all types of pellet equipment and is one of the advanced machinery and equipment widely used internationally.
