In February 2026, Beston Group’s BST-50 biochar equipment officially received pre-approval from the internationally recognized carbon removal certifier, Isometric. At the same time, Beston Group became one of Isometric’s first global biochar equipment partners. This significant milestone reflects our commitment to advancing sustainable solutions. It also solidifies our pioneering position in biochar carbon removal solutions.

How BST-50 Becomes a Pre-Approved Model?

01 Digital Monitoring, Reporting, and Verification (MRV)
- High-frequency Automated Recording: The PLC system records key reaction parameters at minute-level intervals. As a result, it creates a tamper-resistant digital record. This ensures full alignment with Isometric’s audit requirements.
- Full Lifecycle Data Traceability: Sensors cover critical process nodes. They upload operational data and calibration logs to the cloud in real time. Therefore, BST-50 biochar machine meets data retention requirements of 5+ years and delivers reliable traceability.
02 Efficient Pyrolysis Process
- Industrial-grade Operating Performance: An advanced combustible gas system, combined with a dual-cylinder reactor design, ensures 7,200 hours continuous operation time and a stable biochar output of 6,000 tons per year.
- High-quality Biochar Output: The system precisely controls reaction temperature and residence time. Therefore, it consistently produces biochar with H:Corg < 0.7. This ensures durable carbon sequestration for 200+ years.
03 Strict Emission Control
- Methane Leakage Prevention: The system uses a fully sealed combustion design. It recovers syngas for reuse or safely flares it when needed. In addition, pressure monitoring systems detect and mitigate methane leakage risks in real time.
- Multi-stage Exhaust Gas Treatment: The equipment integrates cooling, dust removal, desulfurization, and denitrification processes. Consequently, emissions such as CH₄, N₂O, and CO meet local environmental standards.
What BST-50 Brings to Biochar Suppliers?
Faster Carbon Credit Issuance
Since Isometric has pre-approved BST-50 pyrolysis system, suppliers no longer need to repeat reactor validation. As a result, they can accelerate the Validation & Verification process. This enables earlier issuance of the first batch of carbon credits.
Lower Project Initiation Costs
Because the model is pre-approved, suppliers face a simpler review process and avoid high engineering audit costs. Meanwhile, the Digital MRV system ensures full data compliance, reducing the risk of credit deductions from non-standard manual data.
Less Certification Risk
Through pre-approval equipment, developers mitigate the primary risk of “non-recognition”. This partnership ensures higher compliance certainty and a smoother certification pathway. It providing investors with greater confidence in the project’s eligibility.
