Biochar Carbon Removal Project in Saudi Arabia

Our biochar carbon removal project in Saudi Arabia is being developed in collaboration with CrystalChain, the French dMRV technology provider. We are currently progressing through Puro.earth’s pre-commissioning equipment audit to satisfy the platform’s verification criteria.

Once construction is completed and the biochar plant enters full operation, the facility is projected to generate a minimum of 8,000 CORCs (CO₂ Removal Certificates) annually,delivering high-integrity, fully traceable verified carbon removal credits to participants across the global voluntary carbon market. Our proprietary biochar production technology forms the core foundation enabling this stable, long-term carbon removal performance.

Biomass Pyrolysis Plant Supports Biochar Carbon Removal Project

Continuous biomass pyrolysis plant provides an industrial foundation for biochar carbon removal projects. Mingjie biochar production lines ensure the repeatability of operating conditions, enable automated control of the biomass pyrolysis process, and facilitate the systematic collection of production data.

Key Features of Continuous Biomass Pyrolysis Equipment

• Continuous feeding and discharge: Supports a more stable material flow.
• Automatic temperature control: Helps maintain established operating conditions.
• Gas handling: Supports energy recovery from syngas and thermal energy.
• Production monitoring: Enables the collection of relevant operational parameters.
• Consistent product handling: Facilitates representative sampling and batch record-keeping.
• Data integration: Allows the equipment control system to connect with monitoring and dMRV (Monitoring, Reporting, and Verification) systems.

Continuous Biochar Production Equipment Ensures Carbon Integrity in BCR Project

Continuous Pyrolysis: Reducing Uncertainty in Carbon Accounting

The biochar production equipment utilizes a design featuring sealed, continuous feeding, pyrolysis, and discharge. Feedstock enters the oxygen-free (or low-oxygen) pyrolysis reactor at a constant rate, while temperature, pressure, and residence time are managed via an automated closed-loop control system.

Long-term stability of pyrolysis operating conditions:

Fluctuations in fixed carbon content, H/C ratios, and aromatic carbon structures across batches of produced biochar are minimal. The H/C atomic ratio is a key indicator used in international biochar CDR standards to determine the durability of carbon sequestration. A stable biomass pyrolysis process keeps this indicator within standard thresholds, demonstrating that carbon can remain sequestered in the soil on a centennial timescale.

Stable carbon partitioning:

Carbon from the biomass entering the reactor is consistently partitioned into three streams: fixed carbon in biochar, carbon in combustible gases, and carbon in pyrolysis oil. Minimal fluctuation in carbon model input parameters significantly reduces uncertainty in life-cycle carbon footprint modeling—a fundamental requirement for high-integrity CDR carbon quantification.

Supporting dMRV: Real-time Raw Data Collection

High-integrity biochar CDR projects increasingly rely on digital Monitoring, Reporting, and Verification (dMRV). Continuous biomass pyrolysis equipment integrates online sensors to capture real-time data on biomass feed rates, reactor temperature and pressure, flue gas composition, and biochar discharge rates, automatically uploading this information to a data platform.

The continuous data stream allows for remote verification by third-party auditing bodies, aligning with the dMRV standards promoted by organizations like Puro and Verra, and significantly enhancing the credibility of carbon removal data.

Scalability and Feedstock Flexibility: Ensuring Project Additionality

High-integrity BCR Biochar Carbon Removal Project requires that biomass feedstock does not induce land-use change. Continuous biomass pyrolysis equipment supports 24-hour uninterrupted operation, capable of processing residual biomass such as agricultural and forestry waste, crop stalks, wood chips, sludge, and livestock manure. These systems are equipped with pre-treatment units to reliably process dispersed agricultural and forestry residues.

Large scale biochar production equipment reduces energy consumption and the carbon footprint per unit of biochar, making it easier to achieve biochar project additionality. Continuous biochar production lines can incorporate feedstock traceability systems to meet sustainability certification requirements, such as ISCC. Syngas can be recycled to the reactor as a heat source, displacing fossil fuels. This further reduces the project's lifecycle carbon emissions and maximizes net carbon removal.

Consistent Biochar Quality Ensures Long-Term Carbon Sequestration Durability

The core value of Biochar CDR credits lies in the commitment to permanent sequestration.Continuous biomass pyrolysis processes allow for precise control over carbonization temperatures and residence times, enabling the consistent production of biochar characterized by high aromaticity and low levels of easily decomposable organic carbon.

Ensuring stable quality also facilitates long-term field monitoring, as standardized parameters regarding soil degradation rates can be reliably reused.

Closed-System Process Control Minimizes Leakage and Pollutant Risks

Continuous biomass pyrolysis equipment operates as fully enclosed, negative-pressure system. All gaseous pyrolysis products are collected for resource-recovery combustion or recycling, effectively controlling fugitive emissions. An integrated tail-gas purification unit manages tar and particulate matter, ensuring compliance with environmental emission regulations. This approach eliminates negative environmental externalities, aligning with the Do No Significant Harm principle essential for high-integrity CDR.
