Biochar production equipment uses pyrolysis (heating biomass without oxygen) to convert biomass into biochar, ranging from small kilns/drums to large industrial systems. All are designed for different scales and processing organic waste like wood, coconut shells or agricultural residue into soil enhancers and carbon sinks. For industrial-scale solutions, explore Beston Group’s biochar machine offerings.
Classification of Market-Available Biochar Production Equipment
Biochar production equipment encompasses a range of thermochemical processes, configurations and scales to meet diverse operational needs. Common classsfication as follows:
By Deployment Location
- Mobile Facility: Transportable system for biochar production in multiple locations. Mobile assets are by construction smaller, and often grouped in fleets.
- Stationary (Fixed) Facility: Biochar prodution at a fixed location.
By Production Scale
- Small-scale Artisanal Kilns: Ideal for farms, gardens, educational use, and pilot projects.
- Industrial-scale Plants: Highly automated, continuous systems designed for high-volume commercial production.
By Core Technology
- Pyrolysis: The most prevalent method, heating biomass in the absence of oxygen.
- Torrefaction: Mild pyrolysis at lower temperatures.
- Hydrothermal Carbonization: Uses heated, pressurized water to convert wet biomass.
Beston Group offers stationary, industrial-scale biochar machine based on pyrolysis technology.
How Pyrolysis Turns Biomass into Biochar? – Biochar Machine Workflow
Step 1 – Biomass Prements & Feeding
- Dry and crush biomass to feeding requirements: Moisture Content < 15% | 5mm< Particle Size < 20mm
- Load biomass waste to the silo. Then screw belt conveyor transports bioamss into the inner cylinder of the reactor.
Step 2 – Biomass Pyrolysis into Biochar
- In the inner cylinder (medium-temperature zone), biomass materials undergo drying and semi-carbonization.
- Then the screw pushes them to drop into the outer cylinder (high-temperature zone) for complete pyrolysis, producing biochar.
Step 3 – Syngas & Flue Gas Recycling
- Syngas Recycling: Syngas generated during the pyrolysis process is purified and then used as the heat source for the reactor.
- Flue Gas Thermal Energy Utilization: Flue gas heat is partially used for dryer heating and partially for pipeline insulation to prevent tar and wood vinegar condensation and biochar equipment blockage.
Step 4 – Biochar Discharging
Discharge biochar through the water-cooling discharging system. Normally, the final biochar temperature is ≤45°C.
Step 5 – Exhaust Gas Treatment
After the heat energy is recovered, the final flue gas undergoes multiple dedusting treatment. The emissions meet EU environment standards.
Recyclable Biomass to Make Biochar – Types/Requirements
Common Biomass Types to Make Biochar
- Agricultural Waste: Rice husk, straws, sugarcane bagasse, jute stalks.
- Forestry Waste: Wood chips, sawdust, wood shavings, bamboo waste, eucalyptus bark.
- Food Processing Waste: Coconut shells, palm kernel shells, peanut shells, almond shells, hazelnut shells, olive husks, and coffee grounds.
- etc.
Standard to Choose Biomass Material Types
- Good flowability: Poor flowability can cause materials to stop flowing and accumulate in the hopper (e.g., palm fibers have poor flowability).
- Uniform size: Oversized materials can jam the feed screw, while overly thin materials tend to turn into powder.
- Low dust/powder: Excessive powder in raw materials can clog pipelines and affect biochar quality. (Harder materials, such as coconut or fruit shells, are recommended.)

Carbon Removal – The Fastest-Growing Application of Biochar
Biochar Carbon Removal (BCR)
Plants capture CO₂ from the atmosphere via photosynthesis. Biochar transforms this carbon into a highly stable form that can persist underground for centuries. Thus, BCR become an effective solution for climate change mitigation.
