The company’s newest operation, Wakefield BioChar Facility 4 (WB4), anchors a large-scale circular economy initiative in the forestry-rooted city of Valdosta, Georgia. Operating through a deeply integrated partnership with a major local pulp and paper mill, the facility transforms FSC and SFI-certified pine residues -specifically bark and reject wood chips - into premium biochar. By leveraging carbon finance, Wakefield actively intercepts this biochar from being sold into the metallurgical industry as an emissive reduction agent, redirecting it instead into permanent, verifiable soil sequestration. Beyond high-integrity carbon removal, WB4 delivers transformative agronomic and social co-benefits. The biochar is applied to local agricultural and horticultural soils, where it dramatically enhances soil structure, reduces potent nitrous oxide (N₂O) emissions, and critically improves water retention. This moisture-holding capacity provides a vital shield for local farmers against severe climate volatility in a region historically devastated by drought, such as the 2007 drought that cost Georgia’s agriculture industry $339 million. This project proves that durable climate action can simultaneously drive meaningful economic revitalization and industrial transition in disadvantaged communities.

Carbonsate’s Namibia project implements large-scale Biomass Storage Carbon Removal through the durable storage of encroaching bush biomass in arid savanna regions. Bush encroachment is a widespread ecological and economic challenge in Namibia: native woody species have expanded aggressively over past decades, reducing biodiversity, suppressing grass growth, lowering groundwater recharge, and limiting the productivity of rangelands. Our project addresses this challenge by selectively harvesting excess encroaching bush and storing the biomass in engineered dry storage systems on degraded land areas that are not suitable for agricultural use. The biomass is placed in specially designed storage pits and covered to ensure long-term oxygen limitation and protection from moisture ingress. Namibia’s semi-arid climate, low precipitation, and high evaporation rates provide ideal ambient conditions for dry biomass storage. By combining natural climatic advantages with engineered design, we create stable storage conditions that significantly reduce biological decomposition and associated greenhouse gas emissions. The carbon removed from the atmosphere during the growth of the bush remains locked away for a minimum durability period of 100 years. Our storage sites are carefully selected and prepared to ensure long-term stability, protection from erosion, and clear land tenure arrangements. A core component of our approach is robust Monitoring, Reporting and Verification (MRV). Carbonsate has developed a proprietary sensor-based monitoring system specifically for biomass storage applications. In addition, we conduct on-site flux chamber measurements to quantify surface gas emissions and validate storage performance. This combination of embedded sensing and direct flux measurements provides high-resolution insight into storage conditions and ensures transparency and environmental integrity. The project is implemented in close collaboration with local landowners, farmers, and service providers. Biomass harvesting is carried out using established bush control practices adapted to meet carbon removal requirements. By integrating into existing land management activities, the project ensures operational feasibility while maintaining ecological safeguards. Over time, the project aims to scale across suitable regions of Namibia with abundant encroaching bush and appropriate dry climatic conditions. Namibia offers significant potential for responsible, large-scale biomass storage due to the combination of bush biomass availability, land suitability, and climatic stability. Through this approach, Carbonsate permanently removes atmospheric CO₂, stores biogenic carbon in controlled dry conditions, and contributes to the development of a high-integrity carbon removal pathway. The Namibia project demonstrates that nature-based carbon capture combined with engineered durability and advanced monitoring can provide scalable, transparent, and long-term carbon removal.

Future facility
Nellie is a UK-based company, focused on delivering bio-engineered carbon dioxide removal at a meaningful scale. Its approach centres on converting atmospheric CO₂ into a physically stable solid form, enabling durable carbon storage rather than short-cycle biological sequestration. The company develops and deploys systems that integrate biological CO₂ removal with thermochemical conversion into stable carbon products, forming a complete removal pathway from the atmosphere to long-term sequestration. The project is designed and operated as carbon removal infrastructure, with clearly defined system boundaries suitable for monitoring and third-party verification. Integrated carbon removal pathway: At Nellie’s site in Mwyndy Cross, South Wales, the company operates a modular, scalable CDR system that uses enclosed photobioreactor (PBR) arrays to cultivate microalgal biomass. As the microalgae grow, they remove CO₂ from ambient air inputs through photosynthesis, fixing atmospheric carbon into organic biomass. Proprietary innovations in photonics and reactor design allow the system to achieve high biomass productivity within a controlled, closed loop, enabling traceability and consistency in feedstock quality. This controlled cultivation approach avoids reliance on heterogeneous external biomass supply chains and reduces exposure to land-use and sourcing variability. Once harvested, the biomass is dehydrated and processed via pyrolysis (controlled heating without combustion) to create PhycoChar®, a stable carbon-rich solid that sequesters carbon for centuries when applied to soil, contributing to circular economy outcomes. The durability of storage is intrinsic to the material itself, with carbon stabilised through thermochemical conversion rather than dependent on ongoing biological conditions. Technology characteristics and deployment model: Nellie’s carbon removal systems are designed as modular, scalable, self-contained units, rather than bespoke, site-specific facilities. Each unit integrates biomass cultivation, conversion, and carbon storage preparation within a defined system boundary. This modular architecture allows new deployments to replicate a proven configuration, rather than redesigning the carbon removal pathway for each site. As capacity increases, removals are generated by adding identical units rather than expanding a single complex facility, supporting predictable performance over time. This approach supports consistency across facilities: the same capture mechanism, the same conversion process, and the same storage outcome can be applied repeatedly as capacity scales. This reduces project-specific variability and enables removals to be assessed against a stable reference design, rather than a series of one-off implementations. This repeatability reduces execution risk and simplifies long-term assessment as volumes grow. Position in the broader climate landscape: Nellie’s holistic CDR model, combining engineered biomass growth, controlled pyrolysis, and robust verification, reflects emerging best practices in the carbon removal domain: traceable feedstock, controlled process boundaries, and durable storage outcomes. Operational inputs and outputs are measured at the facility level to support transparent carbon accounting under third-party standards.

The Company: InterEarth is a Climate Change Mitigation Technology Company. We are an internationally owned, Australian private company. Our mission is to accelerate the global production of Premium Quality Carbon Dioxide Removal (CDR) credits with our Dry Stack biomass sequestration technology. The Project: Located in Western Australia ~400km NE of Perth, on our Bowgada Demonstration farm, this project is a significant milestone for InterEarth as we begin our CDR journey. Using our patented “Dry Stack” technology, we have successfully stored our first 49 CORC’s. The Biomass: The woody biomass was collected from a farmer’s property proximal to our 400ha Demonstration farm. It was native Australian hardwood re-growth, cleared during periodic, routine construction of a property-boundary fire break, in compliance with local fire management legislation and regulations. If not for its use as Dry Stack feedstock, the woody biomass would have been in-field incinerated by the farmer returning its captured CO2 to the atmosphere. The Dry Stack: Our above ground “Dry Stack” technology has a number of design features that disrupt biomass decomposition pathways, ensuring woody biomass preserves its contained carbon for +100 years: - An impermeable roof ensures dry storage, which inhibits fungus, rot and mould. - A thick soil covering acts as a fire proof shield and also prevents UV light (and thus oxidation facilitated by light) from reaching the biomass. - The ventilation system prevents anaerobic decomposition from occurring by introducing oxygen to the system, breaking anaerobic pathways. - Mesh ember guards on the ventilation inlets prevent any rogue embers from being drawn into the dry stack from nearby bushfires. - The termite barrier and fumigation system combine to firstly prevent ingress but also eradicate any insect activity from the biomass in the unlikely event of an incursion. The land hosting the Dry Stack is unsuitable for agriculture due to its saline and infertile soils; the Dry Stack cover soil is seeded with shallow rooted plants to mitigate potential erosion. Dry land woody biomass production for Dry Stack CO2 sequestration offers local farmers a net carbon removal alternative land use suited to declining rainfalls as a result of climate-change. The Sampling and Monitoring Program: All biomass is weighted, sampled and analysed for moisture and Total organic Carbon (TOC) at the point of Dry Stack deposition and at regular intervals post Dry Stack closure. Our Dry Stack biomass TOC results demonstrate zero carbon loss, over several years of storage. Further, low-detection-limit gas analysers monitor Dry Stack exhaust gases for CO2, CH4, CO and O2 plus temperature and Relative Humidity (RH). The long-run, Dry Stack exhaust gas data confirms the maintenance of biomass-inert conditions and zero organic gas re-emissions. It also provide us with early warnings of a potential biomass decomposition event. The Future: Completion of the Demonstration Dry Stack and approval of first CORC’s, is an important proof of concept milestone for InterEarth. It provides us with a solid scientific and regulatory foundation for scale up. We are targeting the generation of 10,000 CORCs in our first Commercial Dry Stack, with regular, similarly sized completions, thereafter. We aim to make a meaningful contribution to climate action in the next 12 months.

Named after the sacred hill of Lord Shiva, the Murudagiri Biochar Facility in Karnataka, India, stands at the intersection of history, land stewardship, and climate innovation. Just as Murudagiri — literally, “Hill of Lord Shiva” — has long been a source of strength and identity for the region, the facility draws from the land’s legacy to build resilience for its future. Nestled near the Tungabhadra river and framed by the Kappatagiri hills, this landscape has sustained life for generations through its soil, water, and stone. Today, it supports something new: a pioneering climate infrastructure project that transforms environmental burden into long-term climate value. Across the Gadag District, Prosopis juliflora, a fast-spreading invasive species, has choked farmland, depleted groundwater, and reduced biodiversity for years. Farmers also face challenges managing agricultural residues such as Corn Cobs which are often burned in the open, releasing harmful smoke and particulate pollution. Without intervention, these biomass streams would continue to degrade ecosystems and contribute to atmospheric CO₂. The Murudagiri project changes that trajectory. By converting invasive woody biomass and underused agricultural residues into durable biochar, the facility delivers verified, high-quality carbon removal while restoring balance to the land. The resulting biochar is applied to nearby agricultural soils, improving soil health, increasing water retention in a drought-prone region, strengthening crop resilience, and boosting long-term farm productivity. This creates a regenerative loop: healthier land, more reliable farmer yields, and carbon locked away for centuries. The project also contributes to regional energy and economic transition. Syngas generated during biochar production is used to meet on-site energy needs and, as capacity grows, will provide a low-emission energy source to nearby industries — reducing reliance on fossil fuels and strengthening local energy security. What begins as waste becomes both climate impact and economic value. Beyond carbon removal, the Murudagiri Biochar Facility is deeply rooted in community benefit and environmental stewardship. Local workers are employed across operations, with intentional inclusion of women and youth. Farmers are supported through training programs that build understanding of biochar use, sustainable soil practices, and climate-resilient agriculture. Removal of invasive biomass allows degraded ecosystems to recover, restores native biodiversity, and helps recharge groundwater — critical for long-term regional sustainability. Every credit issued from this project is backed by transparent monitoring, careful documentation, and verified end-use tracking to ensure that carbon benefits are real, durable, and never double-claimed. Murudagiri is more than a facility. It is a reminder that the future of high-integrity climate action in India must be rooted in the soil, the stories, and the spirit of its land. By pairing durable carbon removal with community partnership, the Murudagiri Biochar Facility demonstrates how climate mitigation and sustainable development can advance together in one of India’s most climate-vulnerable regions.

Tapovanam Biochar – Prakruthi is a climate-positive initiative that transforms crop residues, primarily cotton stalks, into biochar — a stable form of carbon that can be stored safely in soil for centuries. The project tackles the widespread challenge of residue burning by turning agricultural waste into a valuable product that enriches soil, enhances water retention, and improves long-term farm productivity. Our biochar is produced through a clean and energy-efficient pyrolysis process, where the gases released are reused to power the system itself, minimizing emissions. The resulting biochar is further developed into a biofertilizer that supports regenerative agriculture and reduces dependence on chemical inputs. Beyond removing carbon from the atmosphere, Prakruthi contributes to rural livelihoods by creating a new income stream for farmers and promoting circular economy practices. The project reflects Tapovanam’s vision to build sustainable, low-carbon farming systems while contributing meaningfully to global carbon removal and soil restoration goals.

Eion’s Twinterstellar 3021 enhanced rock weathering (ERW) project has been developed to remove carbon dioxide from the atmosphere safely, permanently, and verifiably. In 2023, Eion and its partners sourced, transported, and spread ~15,000 tonnes of pulverized olivine on ~9,000 acres of agricultural lands (i.e., on pasture and row crops, specifically corn and soybean fields) in the state of Mississippi, with a few fields across the state line in Louisiana. The olivine was sourced from two quarries: the Twin Sisters Mountain in Washington State and a quarry located in Åheim, Norway. The project uses existing agricultural infrastructure, and our measurement techniques seamlessly integrate with standard agricultural practices, imposing no new burdens on our farm partners. We accelerate the weathering cycle by pulverizing olivine (i.e., greater surface area = faster reaction), a silicate mineral with high carbon dioxide removal (CDR) potential and crystal structure that weathers rapidly. The pulverized olivine has a soil alkalizing value that is comparable to conventional ag lime, a common agricultural input that balances soil pH (helping to maintain healthy soil and agricultural productivity). Once the olivine has been applied, nature takes over. Rain and soil acidity enable the olivine to remove carbon dioxide from the atmosphere and ultimately transport it to the ocean. The Twinterstellar 3021 carbon project fits within the scope of Puro’s Enhanced Rock Weathering Methodology; it meets all requirements and was designed, developed, and implemented adhering to a principle of conservativeness. Eion utilizes a direct measurement approach to quantify the atmospheric carbon dioxide that has been captured and sequestered through the soil-air-rock interface. The approach fundamentally draws upon the accumulation of semi-mobile tracers in the topsoil (i.e., nickel) and the simultaneous depletion of base cations as a clear proxy for alkalinity fluxes (i.e., magnesium) induced by weathering.

Located in Mato Grosso, with a strong commercial presence in the Midwest and North regions of the country, its philosophy is to maximize sustainability, reducing the environmental impacts of its processes through the full use of biomass, promoting a positive social impact in the communities where it operates. Uisa generates more than 3,000 jobs and has strong social partnerships. It supports Florescer Ação Social, an institution that develops projects focused on the human, social, educational, and cultural development of children, adolescents, and adults in the communities of Denise, Nova Olímpia, and the Assari District, in Barra do Bugres, Mato Grosso. As part of its efforts to become a decarbonization platform in the heart of Brazil, Uisa is implementing a bioenergy with carbon capture and storage (BECCS) project integrated with its bioethanol production to capture the highly concentrated biogenic CO2 stream. After concentration and dehydration, the CO2 will be transported to a future injection site in the Parecis Basin, located approximately 25 km from Uisa's industrial facilities. The project is currently in the final geological investigation phase, with well drilling efforts expected to begin soon, with full operation expected in 2029. Approximately 260,000 tons of CO2 will be stored annually, considering the plant's current capacity, with the potential for injection of up to 550,000 tons of CO2, considering future expansions. By producing biofuels (i.e. ethanol and biomethane) with integrated BECCS, Uisa will provide high-integrity carbon credits for hard-to-abate sectors and/or for the production of carbon-negative biofuels, the latter upon retirement of the corresponding credits by Uisa.

BioCirc’s Bioenergy with Carbon Capture and Storage (BECCS) project is a large-scale initiative for permanent carbon dioxide removal from biomethane production. BioCirc owns and operates eight industrial-scale biogas plants across Denmark, producing around 1.7 TWh of biomethane annually. The biomethane is upgraded from biogas generated by anaerobic digestion of biogenic feedstocks such as agricultural residues, organic waste, and manure, all compliant with the sustainability and emission reduction criteria under the Danish implementation of EU Renewable Energy Directive. In this project, five of BioCirc’s facilities - Vinkel, Vesthimmerland, Grønhøj, Favrskov, and Haderslev - will be retrofitted with carbon capture and liquefaction systems. Captured CO₂ will be transported via CO2 semi-trailers to an interim storage hub in the Port of Esbjerg. From there, it will be shipped for permanent geological storage in the Greensand Future Project - a Danish offshore CO₂ storage site in a depleted North Sea oil field at around 1,800 m depth. The project will capture and permanently store approximately 138,000 tonnes of biogenic CO₂ per year, corresponding to more than 800,000 tonnes of net carbon dioxide removals (CDR) between 2026 and 2032, after accounting for life-cycle emissions. BioCirc’s BECCS project is among the first to combine biomethane production with permanent carbon storage under the Puro Standard. By integrating carbon capture into established biogas infrastructure, BioCirc provides a scalable and replicable model for negative emissions compatible with circular bioeconomy principles. Through strong partnerships for equipment, storage and logistics, BioCirc ensures technical reliability and minimizes delivery risks. The project is supported by the Danish NECCS subsidy scheme. First CO₂ injection is planned for mid-2026, following completion of all permits and construction phases across the five capture sites.

BioCirc’s Bioenergy with Carbon Capture and Storage (BECCS) project is a large-scale initiative for permanent carbon dioxide removal from biomethane production. BioCirc owns and operates eight industrial-scale biogas plants across Denmark, producing around 1.7 TWh of biomethane annually. The biomethane is upgraded from biogas generated by anaerobic digestion of biogenic feedstocks such as agricultural residues, organic waste, and manure, all compliant with the sustainability and emission reduction criteria under the Danish implementation of EU Renewable Energy Directive. In this project, five of BioCirc’s facilities - Vinkel, Vesthimmerland, Grønhøj, Favrskov, and Haderslev - will be retrofitted with carbon capture and liquefaction systems. Captured CO₂ will be transported via CO2 semi-trailers to an interim storage hub in the Port of Esbjerg. From there, it will be shipped for permanent geological storage in the Greensand Future Project - a Danish offshore CO₂ storage site in a depleted North Sea oil field at around 1,800 m depth. The project will capture and permanently store approximately 138,000 tonnes of biogenic CO₂ per year, corresponding to more than 800,000 tonnes of net carbon dioxide removals (CDR) between 2026 and 2032, after accounting for life-cycle emissions. BioCirc’s BECCS project is among the first to combine biomethane production with permanent carbon storage under the Puro Standard. By integrating carbon capture into established biogas infrastructure, BioCirc provides a scalable and replicable model for negative emissions compatible with circular bioeconomy principles. Through strong partnerships for equipment, storage and logistics, BioCirc ensures technical reliability and minimizes delivery risks. The project is supported by the Danish NECCS subsidy scheme. First CO₂ injection is planned for mid-2026, following completion of all permits and construction phases across the five capture sites.

Future facility
Radial Timber Australia (RTA), a family-owned timber company based in Yarram, Victoria, specializes in sustainable cultivation, milling, and distributing durable Victorian hardwood products such as decking and weatherboards. Committed to environmental responsibility, RTA sources regrowth or plantation-grown timber and employs a circular economy model to minimize waste and maximize resource recovery. In 2024, RTA enhanced its sustainability efforts by investing in Earth Systems' CPP500 pyrolysis technology to convert wood waste from their operations—sawdust, shavings, peelings, and scrap—into biochar. This biochar, produced at an estimated 500 tons annually, is used as a soil amendment within RTA’s plantations, improving soil health and reducing waste. The facility began operations in July 2024 and is scaling up to full capacity, with plans to add two more units by 2026. The project's financial sustainability hinges on carbon credit sales under the Puro.Earth standard, as the regional biochar market develops. Initially, biochar is applied within RTA’s plantations, supporting a closed-loop approach that reduces emissions, enhances soil quality, and promotes renewable energy. By integrating sustainable timber production with biochar-based carbon sequestration, RTA is pioneering climate-positive forestry, advancing ecological resilience and economic viability through responsible land management.

The EcoNew Brazil Biochar Project is redefining how Brazil turns waste into climate value. Led by EcoNew Energia Sustentável Ltda in Minas Gerais, the project transforms sustainably sourced eucalyptus residues, once burned or left to decompose, into high-quality biochar that locks away carbon for centuries. At the heart of EcoNew’s operations is an advanced BST-50 continuous pyrolysis system, capable of producing 15,000 tons of biochar per year, engineered for precision, safety, and environmental integrity. Through closed-loop heat recovery and state-of-the-art emissions controls, the process achieves durable carbon removal with a minimal environmental footprint. All by-products are responsibly managed, ensuring full compliance with Brazilian environmental standards. The resulting biochar improves soil health, fertility, and water retention - helping farmers cultivate more productive and resilient lands. By valorizing eucalyptus residues from FSC, PEFC, and CERFLOR certified plantations, EcoNew supports sustainable forestry and reduces open burning across regional supply chains. Combining technological innovation with tangible community benefit, the EcoNew Brazil Biochar Project demonstrates how industrial ingenuity can power natural regeneration - advancing Brazil’s low-carbon transition, one tonne of carbon at a time.

Future facility
GSAD Cambodia is spearheading a high-volume, scalable, sustainability initiative through the development of a state-of-the-art biochar production facility in Prey Veng Province. By converting rice husk waste—a by-product of Cambodia’s extensive rice cultivation—into 1500 tons of high-quality biochar monthly, this project is designed to address critical environmental and agricultural challenges. The facility will be positioned to deliver substantial impact across both environmental and economic dimensions. To support financial planning and ensure smooth progress through the pre-production phase, GSAD Cambodia would appreciate consideration of a five-month advance on CORCs, which would bridge early operational costs and accelerate implementation. By promoting circular resource use and organic soil enhancement, the initiative will significantly improve environmental stewardship while boosting agricultural productivity across the region. The project aligns with national climate and agricultural goals, offering a scalable model for sustainable development. GSAD Cambodia’s approach is deeply rooted in collaboration and community engagement. The company has built a strong reputation for working closely with local farmers, agricultural cooperatives, and government stakeholders to ensure the initiative delivers tangible benefits to rural communities. This inclusive model reinforces long-term sustainability and strengthens the project's social license to operate. Central to the initiative is a high-capacity facility capable of producing 1,500 tons of biochar per month by processing 3,000 tons of rice husks. These husks are derived from the province’s annual output of approximately 1.5 million tons of paddy rice, which generates an estimated 450,000 tons of husk waste. By diverting this biomass from open burning—a major source of greenhouse gas emissions and air pollution—the project addresses pressing waste management and climate challenges while creating a valuable agricultural input. The facility will be equipped with Beston BST-50s Biochar Reactor, certified under the Puro standard. Manufactured by Beston, a leading Chinese company known for its innovation and reliability in biomass processing, the BST-50s has been vetted and shown to meet key technical requirements including the ability to produce biochar with a hydrogen-to-organic carbon (H/Corg) ratio of 0.29—well below the 0.7 threshold required for carbon credit eligibility. GSAD Cambodia’s multinational executive team brings over a century of combined experience in agribusiness, operations, human resources, finance, and sustainability. Their leadership underpins the project’s success, ensuring rigorous execution, operational excellence, and strategic alignment with both local needs and global climate objectives. Ultimately, this initiative represents a high-impact opportunity to harness local resources, reduce environmental harm, and catalyze rural economic development. With strong community support and a clear roadmap for scale, the project is poised to deliver lasting benefits to both people and planet.
