Biochar Production Equipment with dMRV System: Verified Data for CDR Projects
For CDR projects, biochar machine requires reliable data management capabilities to support the monitoring, reporting, and verification (MRV). BST-50 / BST-06Quicker feature a highly automated PLC control system with IoT-enabled remote monitoring. All operational data is logged in a tamper-proof format and fed directly into the dMRV system. It supports registry certification and accurate carbon accounting. The pyrolysis equipment enables:
Full Lifecycle Data Traceability
Sensors at key process nodes collect operating data in real time and upload it to the cloud. The system retains data long-term, tracing it from feedstock intake through production to finished biochar output.
Registry API Integration
Production data can be integrated via API with carbon removal registries such as Puro.earth, Isometric, and Rainbow Standard. This adaptability reduces manual reformatting and streamlines project reporting and verification.

Sustainability Requirements for Biomass Feedstock
For CDR projects, registration platforms require that feedstock sourcing be compliant and free from additional carbon emissions, ecological damage, or negative social impacts. Therefore, the following sustainability requirements for biomass sourcing are critical to project compliance:
1. No Land-Use Change (LUC): Feedstock sourcing must not involve deforestation, the destruction of wetlands or grasslands, or the development of ecologically sensitive areas. Otherwise, the land-use change emissions would offset the benefits of carbon removal.
2. No Competition with Food Production: Priority is given to feedstocks such as agricultural residues, forestry residues, and by-products of agricultural processing, rather than directly using food crops or dedicating high-quality arable land to the cultivation of energy crops.
3. Protection of Soil Ecological Functions: Residues such as crop stalks play a vital role in maintaining soil organic matter, preventing erosion, facilitating nutrient cycling, and improving soil structure. Only a specific proportion of residues is permitted for use in biochar pyrolysis equipment.
4. Promoting the Resource Utilization of Waste: Priority is given to utilizing biomass that would otherwise be open-burned, landfilled, or left to decompose naturally (releasing methane). Such feedstocks not only enable carbon sequestration but also prevent additional greenhouse gas emissions.
How Biochar Is Made Using Biochar Production Equipment
Beston Group’s biochar making machine converts biomass into biochar through a four-stage process — pretreatment, feeding, pyrolysis, and biochar collection. Here’s how each stage works.
Step 1 Pretreatment
Biomass is crushed, screened, and dried to meet feeding requirements (moisture < 15%, particle size < 20mm).
Step 2 Feeding
Pretreated biomass is discharged by screw feeder at a controlled rate. It falls onto high-angle belt conveyor, which delivers it into the furnace.
Step 3 Pyrolysis
At 400–500°C, biomass rotates within the biochar reactor for thorough reaction. Volatiles are released and biomass is carbonized into biochar.
Step 4 Biochar Collection
Biochar is discharged from the furnace by a screw conveyor. It is cooled to below 45°C through a water-cooled conveyor before collection.
Note:
Gases generated during pyrolysis are handled as follows:
- Combustible gas (H₂, CH₄, CO): recycled as fuel for the combustion system;
- Hot flue gas: returned to the dryer to preheat incoming biomass;
- Exhaust gas: cooled, de-dusted, desulfurized, and discharged via chimney.
Diverse Applications of Biochar
Soil Amendment
- Forestry: Biochar improves water and nutrient retention in young plantations and enhances forest soil carbon sequestration potential.
- Farmland: Biochar increases soil organic carbon content, reduces nutrient loss, and improves rhizosphere microbial communities.
Construction Material Additive
- Buildings: Biochar is added to cement and concrete to improve strength and thermal insulation performance.
- Roads: Biochar is incorporated into asphalt to enhance crack resistance and pavement durability.
Fossil Carbon Replacement
- Metallurgy: Biochar replaces coke and coal in the smelting processes of steels, silicon, and alloys.
- Industrial Processing: Biochar replaces coal as a fuel source for boilers, kilns, and other industrial facilities.
Livestock Applications
- Feed Additive: Biochar improves gut health and reduces methane emissions from ruminant animals.
- Animal Bedding: Biochar absorbs moisture and odors while reducing ammonia and methane emissions.
New Landscape of Biochar Production: 3 High-Potential Application Pathways
Carbon Removal Projects: Carbon Credits Generation
With a mature methodology, biochar has become a leading carbon removal pathway. For CDR projects, biochar machine should ensure compliant H/Corg levels and data traceability. This is to support carbon sequestration durability and the accuracy of carbon credit accounting.
Biochar market share
- Q1 2026: biochar = 93% of 2.3M-tonne CDR volume
- All-time: 1.29M tonnes delivered, 80%+ of total CDR
Main sequestration pathways:
- Soil environment application
- Construction material applications
Carbon credit market value:
- 1 ton of biochar ≈ 2.2 VCCs(Voluntary Carbon Credits)
- 1 VCC = $120–140/tCO₂

Metal Smelting Projects: Fossil Carbon Replacement at Industrial Scale
By replacing fossil carbon, biochar is becoming a key decarbonization pathway for the metallurgical industry. As carbon border tariffs (like CBAM) and net-zero mandates tighten, steelmakers and smelters are under growing pressure to cut fossil carbon intensity, pushing metallurgical-grade biochar from pilot use toward large-scale procurement. This shift is placing new demands on biochar production equipment:
Equipment requirements driven by this shift:
- High-capacity, continuous production to meet industrial offtake volumes.
- Tight control over fixed carbon % and mechanical strength batch-to-batch.
Emission reduction potential:
- Blast Furnace: Saves ~300 kg fossil carbon/ton steel.
- Electric Arc Furnace: Saves ~30 kg fossil carbon/ton steel.
- Silicon Smelting: Reduces emissions from 4.5 to 0.5 t/ton silicon.

Municipal Sludge Treatment Projects: Reduction + Resource Utilization
Due to the extremely high water content and complex composition, municipal sewage sludge treatment faces high disposal costs and compliance issue. A sewage sludge treatment plant that integrates dewatering, drying and pyrolysis can achieve reduction and harmless treatment, while transforming sludge into valuable biochar.
Reduction Efficiency:
- Up to 90% sewage sludge volume reduction
- Daily sewage sludge processing capacity of 150 tons (BST-50S)
Revenue pathways:
- Waste treatment fees: $30–80/ton
- Sewage sludge-derived biochar market price: $100–450/ton
Meeting EBC Standards: Biochar Quality Tested Across 2 Laboratories
Beston Group’s wood-based biochar has been independently tested by two laboratories — Germany’s eurofins and China’s Zhongke Changhua — and meets EBC standards across most application categories. Biochar’s performance comes from its structure: high porosity for water and nutrient retention, rich functional groups for adsorption, and long-term stability for durable carbon storage. The data below compares our results against EBC benchmarks.
| Parameter Category | EBC Standard | German Laboratory Data (eurofins) | Chinese Laboratory Data (Zhongke Changhua) |
|---|---|---|---|
| H/C Molar Ratio | 0.4 – 0.7 | 0.45 (Generally Meets All Application Standards) | 0.11 – 0.32 |
