Biomass pellets are a solid fuel made from renewable organic matter through processing and pressing. Because of its environmental friendliness, resource renewableness, and economic feasibility, it is considered a green choice to fill the gap in fossil fuels. The specific analysis is as follows:
1. Environmental friendliness:
(1) Low pollution emissions: Biomass pellets are mainly made of crop straw, forestry waste, etc., with low sulfur and nitrogen content. When burned, they produce less pollutants such as sulfur dioxide and nitrogen oxides, which can effectively reduce the occurrence of environmental problems such as acid rain. At the same time, the particulate matter produced by its combustion is relatively small, which has little impact on air quality.
(2) Zero carbon dioxide emissions: Biomass pellets absorb carbon dioxide in the atmosphere through photosynthesis during their growth process. The amount of carbon dioxide released during combustion is basically the same as the amount absorbed during the growth process. From the perspective of the life cycle, zero carbon dioxide emissions are achieved, which helps to alleviate global warming.
2. Resource-Rich and Renewable
Biomass pellets are made from a wide range of raw materials, including agricultural and forestry waste such as crop straw, wood chips, and rice husks. These are renewable resources that are replenished annually through agricultural production and deforestation, unlike traditional fossil fuels, and are not subject to depletion. Processing these wastes into biomass pellets achieves sustainable resource utilization, not only reducing environmental pollution but also converting them into valuable energy, improving resource efficiency.
3. Economic Viability
In some regions, the production cost of biomass pellets is relatively low, especially when the raw material supply is plentiful and transportation distances are short. Compared to traditional fuels such as coal and fuel oil, biomass pellets are price-competitive, and with continued technological advancements and expanded production scale, there is room for further cost reduction. Furthermore, the development of the biomass pellet industry can drive the development of related industries such as raw material collection and processing equipment manufacturing, providing impetus for local economic development and creating employment opportunities.
4. Convenient Application:
High Combustion Efficiency: Biomass pellets have a high density and uniform particle size, allowing for ample contact with air during combustion, resulting in high combustion efficiency and efficient energy release. Compared to traditional biomass pellets, biomass pellets offer more stable combustion and a 20%-30% increase in thermal efficiency.
Easy to Store and Transport: Biomass pellets are compact and dense, making them easy to store and transport. They can be stored in bags or bulk like coal and are suitable for long-distance transportation, meeting energy needs in diverse regions and expanding their application.
Adaptability: Biomass pellets can be used in a wide range of combustion equipment, such as boilers, stoves, and fireplaces. Simply modifying or adjusting the equipment allows them to be used as a fuel, demonstrating their high adaptability and scalability.
