What is Biochar Made of?
For biochar production equipment, most waste biomass can be used. However, due to a lack of utilization awareness, most of the biomass with high recycling value is wasted. Waste biomass can come from a variety of industries. Due to the stable source and high quality of raw materials, waste biomass from the following industries is an excellent choice for biochar production.
Industry
Biomass Type
Forestry
waste branches, tree stump, other logging residue, etc.
Wood Processing
wood chips, sawdust, wood product scrap, waste furniture, etc.
Food Processing

Diversified Application Scenarios of Biochar
Forestry & Agriculture
Promote Plant Growth: Biochar increases the soil’s water retention and air permeability, slowly releasing nutrients and improving the microbial environment for healthy plant growth. It is widely used in agriculture to boost farmland fertility and crop yields.
Ecological Restoration: Biochar restores degraded or contaminated soil by absorbing heavy metals and harmful chemicals while improving soil structure, helping rebuild the natural ecological environment.
Animal Husbandry
Feed Additives: As a feed additive, biochar improves intestinal health and digestion, increasing feed utilization while reducing methane and ammonia emissions.
Shed Bedding: As livestock bedding, biochar absorbs moisture and odor from manure, cutting harmful gas emissions and lowering the risk of pathogen transmission.
Metal Smelting
Low-carbon Reductant Supply: Biochar serves as a reductant in metal smelting, supplying energy while reducing reliance on fossil resources and moving the industry toward decarbonization.
Carbon Tax Relief: By replacing fossil fuels, smelting companies cut their carbon footprint and reduce carbon tax costs, gaining a competitive edge in the carbon market with a charcoal machine.
Construction Industry
Cement Additives: Biochar can partially replace mineral admixtures like fly ash in cement, improving concrete performance and significantly cutting the roughly 0.9 tons of CO₂ emitted per ton of cement produced.
Asphalt Modifier: As a low-carbon asphalt modifier, biochar’s porous structure interlocks with the asphalt matrix and adsorbs light components, increasing binder stiffness and thermal stability.
How to Make Biochar: Workfolw of Biochar Production Equipment
01 Biomass Pretreatment
Crushing: Crushing the raw material < 20mm. This is to ensure that the raw materials are uniform and have good fluidity. Subsequent screening treatment removes biomass fragments that do not meet the size requirements.
Drying: The dryer reduces the moisture content of the raw materials to no more than 15% (if moisture content is too high, multiple dryers are required). Excessive moisture content leads to unnecessary energy consumption of biochar equipment.
Subsequently, the coconut shell enters the reactor through a screw conveyor.
02 High-temperature Pyrolysis
Water Evaporation: As the temperature rises, water inside the biomass cellulose, hemicellulose and lignin gradually escapes.
Volatile Substance Release: At a temperature of 200℃ ~ 500℃, the biomass begins to decompose and release a large amount of volatile combustible gases. These gases are used to heat biochar reactor.
Biochar Formation: When the temperature is greater than 500℃, the release of volatile substances decreases. The carbonaceous components in the biomass begin to convert into biochar.
03 Flue Gas Treatment Recovery
Preheating Air: High-temperature flue gas enters the air-to-air heat exchanger, transferring heat to the air drawn in by the fan.
Heating Dryer: High-temperature flue gas enters the dryer through ducting. It provides heat for drying raw materials, reducing fuel consumption.
04 Combustible Gas Reuse
Gas Collection: combustible gas re-enters the combustion system through the outlet, cyclone dust collector, and pipeline. The parts in contact with the combustible gas are all insulated to prevent condensable substances from clogging the system.
Energy Utilization: The combustion chamber is sealed. The hot air from the air-to-air heat exchanger is used to supply oxygen to the low-nitrogen sealed burner. Then, excess combustible gas enters the exhaust combustion chamber.
05 Biochar Discharging
The combustible gases from the main furnace will be recovered and reused through a cyclone de-dusting system and water seal. The recycled bio-gas can be used for heating the reactor directly. It helps to reduce the fuel cost and make full use of thermal energy.
06 Exhaust Gas Treatment
Heat exchangers, bag filters, desulfurization towers, and activated carbon dust collectors treat high-temperature exhaust gas. This combined exhaust gas treatment configuration enables emissions to meet global standards.

The Hidden Carbon Emission of Improper Biomass Waste Disposal
Forest Fire: Carbon Sink Loss
Uncontrolled Carbon Release: Biomass accumulation fuels forest fires that burn 7-10 million hectares globally each year — about 0.2%-0.3% of total forest area. Globally, forest fires emit an estimated 1.5+ billion tons of CO₂ annually, more than Japan’s total fossil fuel emissions, largely due to the lack of early-warning systems for biomass clearing in most countries.
Permanent Sink Loss: Beyond the immediate CO₂ release, fires destroy the forest’s ongoing carbon sequestration capacity and strip soil organic matter, leaving barren land that can take decades to recover.
Natural Decomposition: Slow Carbon Release
Methane from Decomposition: Left to decompose, biomass releases CH4, whose short-term warming effect far exceeds CO2 — palm waste landfills in Southeast Asia alone emit over 120 million tons of methane annually.
Uncontrolled Composting: Open-air composting without temperature and humidity control triggers denitrification, releasing N2O with a century-scale warming potential 250+ times that of CO₂ — prompting some countries to ban composting outright.
Open Burning: Immediate Carbon Release
Instant Pollutant Release: Open-air burning of agricultural waste releases 2.5-4.3kg PM2.5 and 0.5-1.2g polycyclic aromatic hydrocarbons (PAHs) per ton, driving up respiratory disease rates in burning areas.
Compliance Gap: Even where burning bans exist, the lack of viable alternatives keeps violation rates above 60% in some developing agricultural regions — some rural areas have formed recurring “seasonal haze belts”.
How Biochar Achieves Carbon Removal?
Carbon removal refers to the process of capturing, converting, and storing carbon dioxide (CO₂) from the atmosphere through artificial technology. The biochar carbon removal process can be divided into the following key stages:
01 Photosynthesis: Carbon Capture
Carbon capture is the first step of carbon removal, where plants absorb CO₂ from the atmosphere through photosynthesis and convert it into organic matter. During their growth, plants store carbon in their bodies, laying the foundation for subsequent carbon transformation. >Subsequently, the coconut shell enters the reactor through a screw conveyor.
02 Biomass Natural Cycle: Carbon Release
If plant biomass is left to degredation or is incineration, the carbon stored within it will be released back into the atmosphere primarily as CO₂ or methane. Therefore, in the natural cycle, the carbon in biomass may be released again, contributing to the carbon re-emission process.
03 Biomass Pyrolysis: Carbon Sequestration
To prevent carbon release, biochar production intercepts this natural cycle through pyrolysis. Heating biomass in a low-oxygen environment, a stable carbon-rich substance, biochar, is formed. It turns carbon into a not easily degraded form, thereby sequestering it.
04 Biochar Application: Carbon Removal
Biochar’s carbon removal efficacy is only realized when it enters durable environments. Particularly in soil and construction materials, biochar can remain stable for long periods, preventing the carbon from re-entering the atmosphere and ensuring its long-term carbon removal potential.
