Carbon Footprint Analysis of Biomass Disposal Methods
Plants convert atmospheric CO₂ into organic matter through photosynthesis and store it in the plant body. When the plant’s life cycle ends, waste biomass is formed. Generally, waste biomass will degrade naturally, and the carbon in it will return to the ecosystem. Human intervention in biomass processing will affect its carbon footprint. The way biomass is disposed not only affects its environmental impact, but also determines the carbon sequestration or emission path. Different treatment methods have different effects on carbon footprint:
Pyrolysis
- Carbon Conversion: Biomass pyrolysis plant converts organic carbon in biomass into biochar with high carbon content. In addition, pyrolysis forms a portion of combustible gaseous hydrocarbons. It can be recycled as energy to reduce dependence on fossil fuels.
- Carbon Sequestration: Biochar has strong stability and durability in the soil. Studies have shown that it can exist stably in the soil for hundreds of years. It not only fixes carbon in the soil, but also improves soil structure and increases soil fertility.
- Carbon Emission: Usually, the gaseous part of biomass pyrolysis machine still produces CO₂ during the combustion process. However, this part of the carbon itself comes from the biomass itself, without additional carbon sources.
Eco-Friendly Carbon Footprint Rating: ⭐⭐⭐⭐⭐
Composting
- Carbon Conversion: Composting is a controlled microbial decomposition process. It breaks down organic matter into CO₂ and water. At the same time, some of the organic matter is converted into humus, which serves as nutrients for plant growth.
- Carbon Sequestration: Humus produced by composting can store carbon in the soil. However, this storage is relatively unstable. The carbon in the humus may be gradually decomposed by microorganisms over time and released back into the atmosphere.
- Carbon Emissions: Composting releases CO₂ and CH₄, especially under anaerobic conditions. Among them, the greenhouse effect of CH₄ is much greater than that of carbon dioxide. Even under aerobic conditions, the release rate of CO₂ is relatively fast.
Eco-Friendly Carbon Footprint Rating: ⭐⭐⭐
Incineration
- Carbon Conversion: During combustion, the carbon in the biomass is almost completely converted to CO₂. In addition, some harmful substances such as NOx and SO₂, ash, are generated.
- Carbon Sequestration: There is no carbon sequestration during combustion. The conversion process is almost instantaneous, resulting in the rapid release of all carbon into the atmosphere in the form of carbon dioxide.
- Carbon Emission: Combustion is a direct route to carbon emissions, with almost all carbon converted to CO₂, instantly increasing the concentration of greenhouse gases in the atmosphere. Despite the heat source obtained from the process, incineration is still the treatment method with the highest carbon emissions.

Types of Biomass Recyclable in Biomass Pyrolysis Plant
Biomass Pyrolysis Process: Breakdown to Reinvention
Due to its high efficiency and sustainability, biomass pyrolysis plant has become the preferred method for recycling waste biomass. Pyrolysis in biomass refers to the decomposition of biomass by heat. Inside biochar reactor, the reaction goes in a micro-oxygen high temperature environment. Under high temperature, the complex organic compounds in the biomass (such as cellulose, lignin, and hemi-lignin) undergo chemical structural changes and break into simpler gas molecules. Ultimately, the reaction leaves behind a carbonaceous material with a high carbon content, biochar. The following is the specific material change process:
Hemicellulose
It is a loosely structured polysaccharide that decomposes quickly during pyrolysis. It begins to decompose at a relatively low temperature, generating a large amount of volatile organic compounds. These substances form wood vinegar and tar after condensation. Hemicellulose also releases a large amount of combustible gases when it decomposes, especially CO, CH₄, and other light hydrocarbon gases.
Cellulose
Cellulose is a high molecular weight polysaccharide composed of glucose molecules easy to decompose in biomass pyrolysis reactor. As temperature rises, the sugar units in the cellulose molecules break, generating combustible gases (CO, CH₄, etc.) and volatile organic compounds (forming wood vinegar and tar after condensation). A very small amount of incompletely decomposed residues forms biochar.
Lignin
Lignin is a complex aromatic compound with high chemical stability. It is the main carbon source for biochar production. Inside biomass pyrolysis equipment, the aromatic structure of lignin decomposes at high temperatures to generate relatively stable biochar. At the same time, it also releases aromatic organic compounds (components of wood vinegar and tar) and a small amount of hydrocarbon gases.
Working Process of Biomass Pyrolysis Machine
01 Biomass Feed
02 Biomass Pyrolysis
- First, the reactor is preheated by the burner. Preheating uses external fuel (natural gas, diesel, LPG, etc.)
- In the initial stage, the internal moisture of the biomass gradually evaporates.
- When the reaction temperature is stable, the organic volatiles in the biomass are precipitated. Among them, the combustible gas component re-enters the burner. It continuously supplies energy for the subsequent pyrolysis reaction.
- Finally, the stable carbon in the biomass forms biochar.
03 Biochar Collection
04 Gas Reuse
Flue Gas: High-temperature flue gas enters the heat exchanger to preheat the air supplied to the burner. Additionally, the high-temperature flue gas enters the drying furnace to provide heat for removing moisture from the biomass.
Combustible Gas: The gaseous hydrocarbons separated from the biomass, which are combustible gases, enter the dust removal system for cleaning. After purification, the combustible gas is sent to the combustion system to power the operation of biomass pyrolysis machine.
05 Exhaust Gas Treatment
Economic Benefit Analysis of Biomass Pyrolysis Plant
Reduce Biomass Disposal Costs
Traditional waste disposal methods, such as landfill or incineration, are often accompanied by high transportation, handling and environmental compliance costs. However, biomass pyrolysis equipment offers a highly efficient alternative. By converting waste materials into valuable products, landfill fees and waste disposal expenses are reduced. In addition, the reduced volume of waste after pyrolysis also reduces the cost of waste transportation and disposal.
Valuable Biochar for Sale
As main biomass pyrolysis products, biochar has become an important eco-friendly product due to its multiple applications in agriculture, animal husbandry and construction. Especially in the agricultural field, biochar can improve soil fertility and improve water retention capacity, bringing environmental and economic benefits. In addition, biochar can also be sold to manufacturing industries that focus on sustainable materials, providing another source of income for plant investors.
Participate in CDR Market
By sequestering carbon from biochar, biomass pyrolysis plant can participate in the carbon credit market. Carbon credits can be sold to companies and organizations seeking to offset carbon emissions. This provides a continuous income stream for biomass carbonizer machine. The global push for net zero emissions makes carbon credit trading a valuable opportunity. In addition, Governments also provide financial incentives for carbon removal projects.
