Wood Pellet Mill: Turn Biomass Material into Energy

By Jack Huang    Oct 17, 2017

In recent year, renewable energy becomes hot around the world. As a typical renewable energy, biomass energy develops rapidly owing to their characteristics of renewable, low carbon, environment friendly. What is biomass energy? The biomass energy refers to the organics which produced by plants through photosynthesis. Biomass energy contains residues forestry and agricultural residues, animal waste, energy crop and the house refuse, etc. As a green clean energy with near-zero net carbon emissions, the biomass energy is widely used in the world.

Biomass energy is a clean renewable resource. It contains little nitrogen and no sulfur, and the carbon emissions are close to zero. A study suggests the earth's annual total energy of about 140 billion to 180 billion tons, equivalent to the current world's total energy consumption of 10 times. China has a vast territory and abundant biomass resources. According to official statistics, the available for development biomass resources can reach 5.4 billion tons coal at least.
In term of the several of biomass energy transformation measures, biofuel is undoubtedly suitable for China's national conditions and that is an efficient way. Meanwhile, this way is one of the most mature, simple and feasible way. We can get a better burning effect without making a big change for existing burning machine. The biomass combustion technology is better for promoting the development of biomass energy technology and making a big contribution to protecting the environment, improving the ecology, and advancing peasants living standard.

Wood pellet is a typical type of biofuel, which has many advantages in environment and society. How to turn biomass materials into pellets? We must mention wood pellet mill, a necessary link for pellet making. GEMCO is a wood pellet machine manufacturer, also providing feed pellet mill and briquetting machine. GEMCO provides more choices for choosing the biomass energy machine. Besides, we have rich experience in building complete pellet plant according to your needs.

Application of biomass energy

As we mentioned above, biomass materials exists in every aspects of our daily life, such as wood chip, straw, peanut shell, bagasse, etc. Wood pellet mill gives more options for biomass energy application, including heating, power generation, animal feed and fertilizer.
  • Heating: making biomass materials into wood pellets or briquettes with pellet mill, which can be applied into civil heating and domestic energy.
  • Power generation: biomass materials can be used for power generation. Compared with fossil energy, biomass energy is more clean and environment friendly.
  • Feed: using feed pellet mills to make feed pellets from biomass materials. Feed pellets apply for livestock farm or Backyard farmers.  
  • Fertilizer: biomass energy can be made into biofertilizer, organic fertilizer and compound fertilizer.
Take the Jilin province as an example. Jilin province has abundant resources. In 2012, Jilin collected straw resources 36 million tons. Total energy use can reach 12 million tons annually that equal to 6 million tons coal. Not only generate electricity by using the straw resources but make pellets or briquettes for heating that are environmental and efficient.
In term of generating electricity by using straw energy, Jilin has completed five projects; the total installed capacity is 157 MW; the years of use are about 11.5 million tons. Besides, Jilin has found a country straw pellets burning project, and form an industry chain which contains fuel processing, cooking heating and central heating. The pellets and the new stoves are used for heating in towns and villages that brings about a striking effect.

Biomass Energy Market

wood pellets consumption trend


According to the present situation, the idea of using biomass energy in Europe is worth learning like improving energy efficiency and taxing on fossil energy. In the western country, the biomass energy development accounts for 60% of renewable resources, and the solar energy, wind energy, geothermal energy add up to 40% or less.
Sweden's biomass energy accounts for the first in its energy consumption structure. It has surpassed the fossil energy. How can do that? Because Sweden has a policy: you need to tax if you use the fossil energy. Price is crucial in the energy market, it determines demand. The Sweden government did not add additional subsidies to biomass energy. All kinds of renewable energy are competing in the energy market after the carbon tax increases. Why the biomass energy accounts for the bigger percent? That indicates the biomass energy has a strong competitiveness.


It is noteworthy that China's biomass resources utilization is still facing many problems like the high cost of collection, the immature price system, lack of relevant environmental emission standards and so on. The biomass energy future development direction is diversified. As we know, the ethanol is made from corn, but we can make the ethanol from maize straw that has succeeded in the United States. The corn becomes a universal product in many industries in future, including the agricultural feed and energy product. Pellet is a good example. As we know, Jilin has 4 million straws. These straws have 5 or six other usages like return the grain plots to forestry, use for feed, energy or others.


All in all, biomass energy has wide application around the world and become more and more important. Meanwhile, biomass pellet machine (wood pellet mill, feed pellet mill and briquette machine) plays an vital role in the world.
