The biochar production project utilises eucalyptus and pine plantation residues, such as logs and branches, as feedstock to produce high-quality biochar. Sourced from sustainable plantations in Queensland, Australia, these materials are processed to support carbon sequestration and improve soil health for agricultural and environmental applications. The project employs the Tigercat 6050 mobile pyrolysis unit, which efficiently transforms timber waste into biochar through a controlled thermal decomposition process. This technology ensures high quality biochar while minimising emissions and energy use. Additionally, it enables pyrolysis in situ, allowing the unit to move between sites. The Carbonator features air curtain technology, which helps minimise emissions by recirculating pyrolysis gases for secondary combustion.

The Sanbra Foods Biochar project is establishing a biochar production facility in Ghana’s cocoa-growing region. Operated by Sanbra Foods, a trusted agricultural processor with a robust network of smallholder farmers in Ghana, the project will convert an estimated 15,800 tons of cocoa pod husks annually into high-quality biochar through thermal decomposition using a rotary kiln pyrolysis system. This initiative is designed to both mitigate climate change and improve smallholder farmer livelihoods. Biochar produced will be applied as a soil amendment on farms and community land to increase crop productivity, improve soil health, and sequester atmospheric carbon for over 1,000 years. In the absence of this project, cocoa pod husks are left to decay and emit CO₂ and methane, contributing to climate and air quality issues. This project addresses a critical challenge in the Ghanaian cocoa industry: the lack of sustainable waste disposal and declining soil health due to continuous monoculture practices. By thermochemically stabilizing this agricultural waste, the project creates a carbon-rich material that, when applied to soil, improves nutrient retention, water-holding capacity, and microbial activity—key to long-term agricultural resilience. The project is expected to remove an estimated 8,500 tCO₂e per year and generate certified CORCs under the Puro.earth biochar methodology. Terraton is a US technology company, a project developer, and is the project owner for the Sanbra Foods Biochar project. Terraton is building the first and only Carbon ERP (C-ERP) solution and is focused on making Carbon Dioxide Removal (CDR) businesses more accessible and scalable. As global emissions continue to rise, Terraton's mission is to facilitate the setup of thousands of carbon removal facilities in the coming decade, aiming to remove up to 10 gigatons of CO2 annually. Through its innovative technology platform, Terraton provides tailored solutions for CDR facilities, helping to reduce the complexity and risk associated with carbon capture operations. The platform includes templates to help businesses get started, tools to optimize agricultural waste, and access to financing for building more carbon removal facilities. Additionally, the platform streamlines the process of creating, selling, and purchasing carbon credits, transforming carbon capture into a practical, profitable business by partnering with agricultural businesses in emerging markets.

CORC 1000+

Future facility

Enhanced Rock Weathering (ERW) accelerates the process of natural weathering, a slow carbonation process that is estimated to absorb approximately one billion tonnes of CO₂ from the atmosphere each year. By spreading mineral-rich crushed silicate rock on local agricultural land, this nature-based process speeds up the rate of carbon dioxide removal (CDR) while bringing co-benefits to farming communities. The process begins when atmospheric CO₂ dissolves in rainwater, forming carbonic acid. As this slightly acidic water infiltrates soils, it reacts with crushed silicate rock applied by UNDO. The carbonic acid reacts with minerals such as calcium- and magnesium-bearing silicates, releasing cations and forming bicarbonate ions. This bicarbonate gradually moves through the soil and river systems, eventually reaching the ocean, where the carbon is locked away over geological timeframes. During the weathering reaction, carbonic acid is consumed, releasing cations from the mineral structure, which can then charge balance bicarbonate ions in solution. Given that this is the acceleration of a natural process, there is no ongoing physical human intervention required to capture, manage or durably sequester the CO₂ beyond the sustainable sourcing, crushing, haulage and spreading of the rock. Once the rainwater reacts with the silicate rock, the carbon dioxide removal process takes place naturally over time. Without the intervention of crushing, haulage and spreading, feedstock would remain in situ - either stockpiled or in the geological formation - leading to a negligible counterfactual scenario. The feedstock spread in Ontario has been selected based on its favourable mineralogy and is sourced from an existing mining operation in partnership with UNDO. The rock is mined, crushed, hauled to farms, loaded and spread using existing haulage and agricultural networks. Intensive sampling is conducted across monitoring sites to quantify sequestration, with data from these sites extrapolated across the operational area. Because ERW leverages existing, well-proven technologies from across the mining, haulage and agricultural industries, it has very low barriers to scale. UNDO employs multiple complementary approaches to quantify carbon dioxide removal, with a primary focus on Total Cation Accounting (TCA). This method provides an independent verification by estimating net export of cations from the near field zone. TCA involves strong acid digestion of soils followed by ICP-MS/ICP-OES analysis of major cations, allowing UNDO to determine how much silicate-rich rock has weathered and left the system. This combination ensures robust verification of our carbon removal quantification. TCA is supported by traditional measurement techniques: analysing exchangeable soil cations and monitoring pore water composition (including major cations, anions, and total alkalinity) from in-field sites. These measurements allow us to calculate carbon dioxide sequestration through charge balance calculations. Additionally, calcimetry measurements are employed to quantify secondary carbonate formation at high application densities, critical for accurately constraining silicate weathering kinetics across all operational conditions.

Fasera is a world leader in sustainable businesses in the push to net-zero. The Fasera Terrestrial Storage of Biomass project joins our established Biochar and Environmental Planting projects to bring a third stream of carbon removal credits online. Project Overview: Fasera takes the remnant biomass from our eucalyptus oil distillation operations, that is not suitable for pyrolysis and which otherwise would be burnt in situ to mitigate summer fire risk and stores it in anaerobic chambers, excavated on nonarable land on our Canterbury Farm, which is also where our distillation operations take place. Facility Details: An initial 14ha site has been chosen for the facility with the capacity of 70 - 100 chambers with each holding approximately 1,000 tons of oil mallee Biomass. Each chamber is fitted with probes to continuously monitor temperature and humidity to ensure stable storage conditions. Fasera also operates a remote weather station at the site to continuously monitor and record environmental conditions. The facility is in Kulja, in the Wheatbelt region of Western Australia. It is a remote, dry, low rainfall area, >300 mm pa, making it an ideal site for the permanent storage of carbon. The site will be rehabilitated with native grasses and small shrubs being encouraged to regenerate on and between the chambers. Our Biomass: Typically, mature oil mallees comprise 20% leafy biomass from which Fasera extracts eucalyptus oil and 80% above ground woody biomass. This woody biomass is perfectly suited for terrestrial storage and otherwise has no viable use in this remote location. Our resource is already established through stands of mature oil mallees that will be harvested for oil, setting them up for future continuous coppice harvests. The remnant woody biomass is chipped, dried and buried in TSB chambers, preserving the organic carbon for centuries.

Mast is the world’s first and only end-to-end, technology-driven reforestation company. As wildfires intensify across the western United States, forest loss is accelerating, leaving landowners without affordable or effective solutions to restore their land. Mast addresses this challenge by providing rapid, climate-resilient reforestation at no cost to landowners, funded by the sale of high-quality biomass burial carbon removal credits. Through our subsidiaries, Silvaseed—a trusted, 130-year-old nursery and the largest seed supplier in the Western U.S.—and Cal Forest Nursery, California's leading seedling provider, Mast grows over 36 million seedlings each year. Our integrated services cover every stage of reforestation, from wild seed collection and seedling cultivation to site planning, planting, monitoring, and carbon project development. At Mast Wood Preserve MT1 in Montana, we’re pioneering our restorative approach by combining biomass burial with long-term land stewardship. The biomass for this project consists of fire-killed ponderosa pine trees, most of which was cut and stacked after the 2021 Poverty Flats Fire. Initially slated for burning—which would release stored carbon back into the atmosphere in 2025—the logs will instead be permanently buried at a dedicated storage site, in dry, oxygen-limited conditions designed to prevent decomposition, and durably remove carbon from the atmospheric cycle. The MT1 project will permanently sequester approximately 5,000 tonnes of CO₂e. The burial site is protected by an open space easement for at least 100 years, and environmental sensors will continuously monitor site conditions and greenhouse gas emissions. After burial, the area will be restored with native grasses, supporting its ongoing use for grazing. To ensure long-term project integrity, Mast will establish an endowment fund dedicated to future monitoring, maintenance, and stewardship. Site operations are currently underway, with biomass burial completion expected by May 2025. Carbon credits from the project are anticipated to be issued as early as September 2025.

Biocarbon Tech Asia is a pyrolysis project being developed in Malaysia that will pyrolyse palm trunk waste, bamboo and other agricultural residue to produce biochar and green energy while sequestering carbon. The project intends to establish a truly circular model for operating palm plantations that will not only upcycle every waste stream generated on site but also remove carbon, reduce fertiliser dependencies and meet local energy requirements. The palm processing activities in Malaysia’s palm plantations generate several waste streams like empty fruit bunches, kernel shells, waste effluent, mesocarp and palm tree trunks. Every year, these plantations fell old oil palm trees that have reached the end of their productive life to facilitate replantation. The poor physical and chemical properties of the trunks of these trees make them impossible to be repurposed for traditional timber and plywood uses. Thus, they are broken up, piled in a line and left to decompose on the plantation site, taking up to 5 years to fully compost. Composting is a form of recycling that does not fully utilise the potential of the material. Furthermore, since this felling occurs on a daily basis, the emissions that the composting activities generate on the entire site cannot be ignored. Located in Sabah, East Malaysia, Biocarbon Technologies has already implemented several initiatives on its palm plantation to make their site operations green. Some examples include anaerobic digestion plant, biomass boiler to generate green electricity and running biomethane-fuelled truck fleets. However, it soon became clear that pyrolysis would be a better way of handling palm tree trunks than composting, both economically and environmentally. Diverted from the being left to compost in the fields, the palm trunks will be chipped, dewatered and dried before being pyrolysed by two pyrolysis units to sequester carbon and produce sap (a substance used to enhance biogas production), biochar and syngas. The syngas, when burned, will produce green energy that will power different plantation operations. Through an existing steam generator, it will produce green electricity to meet local energy requirements. It will also support energy requirements of torrefaction, a process that will produce black pellets, a fuel essential for steel industry’s green transition. The biochar will be used on the plantation to reduce fertiliser requirements as well as sold for both, soil and non-soil applications like construction material substitutes.

CarboHeroes will remove up to 0.5 gigatons of CO2 from the atmosphere by 2050 through a circular economy model based on production and application of biochar, which is explicitly highlighted as key carbon removal technology with several co-benefits to fight climate change by IPCC (Intergovernmental Panel on Climate Change – a body of the UN) and UNFCCC. Biochar will be incorporated into the soil, increasing its health while at the same time sequestering massive amounts of carbon. In this way we combine sustainable agriculture with a significant carbon reduction effect by using agricultural waste. Biochar is produced by thermal carbonization (“Pyrolysis”) and is one outstanding way of establishing circular agricultural models. Biochar’s porous structure and internal surface area enable it to store water and nutrients and bind pollutants. In addition, a significant amount of the carbon of the source material remains stable the long term, effectively removing CO2 from the atmosphere. The first module of the scalable business is planned in Costa Rica. We have secured an annual amount of >80,000 tons wood residue as input material for the pyrolysis process. Furthermore, we can access a multiple of tons per year from the coffee, pineapple, and sugarcane industry. We will help companies achieving their net-zero goals in creating, issuing, and trading high-quality carbon credits with the permanent fixation of the carbon in the soil. In addition, there are numerous applications for biochar in markets inside and outside agriculture that make processes and products more environmentally friendly and sustainable. The business model is based on the massively growing carbon credit market in the first phase, supplemented by selling into biochar application cases in the second phase. Of course, the usage (& sales) of thermal energy is considered in all phases. The company's impact is manifold.

The Three Mountains Cocoa Biochar project is establishing a biochar production facility in the Ashanti region of Ghana. Three Mountains Cocoa is a premium organic cocoa processing company that has earned a reputation for prioritizing the welfare of farmers, the environment, and the surrounding communities. By working directly with their network of 2,000 local farmers, the Three Mountains Cocoa Biochar project aims to collect 16,000 tons of cocoa pods annually for conversion into biochar. This project will not only create a new revenue stream for farmers but will also help address climate change by converting agricultural waste into carbon-negative products. The partnership will promote sustainable farming practices while supporting carbon sequestration efforts, ultimately reducing greenhouse gas emissions and enhancing soil health, generating 8,000 tons/year CO2 of carbon credits using high-technology biochar production. The produced biochar will be blended with manure and distributed to over 2,000 smallholder farmers in the Ashanti region of Ghana who supply Three Mountains Cocoa with their cocoa beans to be used as a soil amendment mixed with pig manure and applied to cropland and forest surfaces. These smallholder farmers will have the opportunity to earn an additional $5-8 per ton of cocoa pods that would typically go to waste. The biochar will enhance soil health and boost agricultural yields for the smallholder farmers working with Three Mountains Cocoa. In addition, the project will contribute to overall improvements in soil quality and water health, helping to mitigate climate change impacts while supporting the preservation of surrounding natural habitats, including a UNESCO-protected forest. In the baseline scenario, cacao pods are left to decay without being utilized for energy production. This accumulation of thousands of tons of cacao pods placed a significant strain on the environment and local communities. As the pods decomposed, they released large amounts of CO2e and methane, similar to the emissions from open burning. Additionally, the decaying pods attracted pests and contributed to downstream water pollution. The first crediting period of this single-site project is expected to remove an estimated 8,000 tons of CO2e (tCO2e) annually, leading to the removal of an estimated 56,000 tCO2e over a 7-year period.

A portion of the biochar is used to enhance soil quality, while another part is incorporated into cement and concrete. The facility uses a continuous pyrolysis process that not only meets local environmental standards but also carefully controls emissions to reduce our impact on the community. Our post-treatment technology, co-developed with our internal startup ‘Arbon’, ensures that the biochar possesses the ideal properties for these applications, enabling permanent carbon sequestration. The developed biochar can be used to enhance performance of concrete and partially replace usage of clinker and cement in concrete applications leading to further reduction in carbon emission from the construction industry. In soil applications, our biochar enhances crop productivity, which can lead to increased income for farmers and promote sustainable agricultural practices by enriching soil fertility. Moreover, transforming agricultural waste into biochar contributes to addressing the PM 2.5 pollution issue. Many farmers in Thailand traditionally burn leftover materials after harvest to prepare for the next planting cycle. Our goal is to purchase agricultural waste, such as rubber tree stump and other residues, to discourage burning and provide farmers with an additional income stream. Looking to the future, our plans extend beyond producing biochar for our own mining site rehabilitation. We are also exploring solutions for utilizing inorganic waste to accelerate weathering (EW), which is another technology for carbon sequestration. We are optimistic that the sale of carbon credits will enable us to achieve significant carbon sequestration targets. Through these innovative efforts, SCG Cement is at the forefront of environmental stewardship, paving the way for a sustainable future while supporting the agricultural community in Thailand.
