The CarbonCycle001 Rieden Biochar Project is located in southeastern Germany and transforms low-value wood residues into high-quality biochar, creating a stable and measurable method of removing carbon from the atmosphere. Utilizing locally sourced wood chips from PEFC-certified forests, the facility uses pyrolysis to convert the biomass into durable carbon stored in biochar, which is then applied in agricultural systems.
Each tonne of biochar produced by the project sequesters 2.86 tonnes of CO₂ equivalent, with a permanence of over 1,000 years. The resulting biochar is used in multiple cascading applications—beginning with animal feed and litter, then transitioning into soil where it enhances fertility and water retention. The project is certified under the Puro Standard and has been independently audited to ensure compliance and transparency in carbon accounting.

Biochar-based Carbon Removal
Based on 2.86 tCO₂e sequestered per tonne of biochar
Ongoing since 2020
Improved soil fertility, reduced methane emissions, and sustainable rural economic development
The project has a strong commitment to environmental and sustainable development that benefit local communities through the following contributions:
Environment
The use of pyrolysis prevents emissions that would otherwise result from open burning or natural decomposition of biomass. By stabilizing the carbon, the project achieves permanent sequestration while improving soil health, water retention, and nutrient cycling. The application of biochar in agriculture reduces reliance on synthetic fertilizers and lowers methane emissions when used in animal husbandry.
Community
The project supports local farmers by offering a value-added soil amendment that boosts yields and resilience. The use of biochar also helps protect groundwater from nitrate leaching. The project is situated in a rural agricultural area and enhances local sustainability through responsible biomass utilization.
Employment
Carbon Cycle is a family-owned enterprise that has expanded its capacity through investment in human capital and operational expertise. The carbon finance generated by CORC sales enables ongoing employment, supports rural economies, and provides a stable platform for scaling future production.
Economic Acceleration
Revenues from carbon removal certificates are essential for the business model. They reduce the market risk associated with biochar sales, allowing the company to subsidize product pricing and attract new customers. This financial model accelerates growth and multiplies the project’s climate impact through reinvestment in infrastructure and outreach.
The project follows the Puro Standard and has been verified by third-party auditor Bio.inspecta. All carbon removals are certified ex-post, ensuring real, measurable, and permanent climate benefits.
Verification: This project is verified by the Verified Carbon Standard.
