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:
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.
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.

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.
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.
Biomass is crushed, screened, and dried to meet feeding requirements (moisture < 15%, particle size < 20mm).
Pretreated biomass is discharged by screw feeder at a controlled rate. It falls onto high-angle belt conveyor, which delivers it into the furnace.
At 400–500°C, biomass rotates within the biochar reactor for thorough reaction. Volatiles are released and biomass is carbonized into biochar.
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:
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.

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:

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.
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 |
| Heavy Metal | Depends on Specific Application | Fully Meet All | Fully Meet All |
| PAHS-8 | Depends on Specific Application | Fully Meet All | / |

Core mechanical components are designed and tested to European safety standards. Advanced engineering features, such as dynamic sealing designs and dual-explosion-proof systems, allow operators to work safely. Our biochar machine for sale is CE certified:
Biochar production equipment with high-end flue gas treatment (cooling, denitration, desulfurization, and wet electrostatic precipitator) ensures particulate and VOC emissions comply with EU Industrial Emissions Directive (IED) limits. This ensures smooth local environmental permitting in the most regulated markets.
Life Cycle Assessment (LCA) is used to quantify all emissions and carbon sequestration from biomass acquisition to biochar application, allowing the calculation of the project’s net carbon removal.
dMRV is a digital monitoring system that can monitor, report, and verify all data of the biochar CDR project lifecycle management. It ensures the authenticity, traceability, and auditability of carbon removal.
In short, LCA defines what should be measured across a biochar CDR project’s lifecycle, while dMRV supplies the real-time, verifiable data to track and validate those measurements. Below, we break down how Beston Group supports both LCA and dMRV requirements at each of the five project stages.
Collect agricultural and forestry residues, crop straw, and logging leftovers. All biomass must be traceable and sustainably sourced, meeting legal harvesting and collection requirements.
Through technical vetted biochar production equipment, raw biomass undergoes pyrolysis to produce biochar.
Transport biochar to the application site.
Applied to soil, blended into construction materials, or used in other long-term carbon storage pathways.
Carbon credits are issued based on verified net carbon removal.
