Enable Earth is launching a pioneering biochar production project in Wiang Pa Pao district, Chiang Rai, Thailand, to tackle air pollution and improve soil health. The project focuses on converting leftover corn plant residues—usually burned in fields, worsening air pollution—into biochar, a material that enhances soil fertility while capturing carbon.Using specialized pyrolysis technology, the project aims to produce biochar efficiently, selecting Earth Systems' equipment for initial operations. The biochar will be mixed with compost and distributed to local farmers to improve crop yields and reduce reliance on chemical fertilizers. The initiative is expected to remove and store carbon dioxide (CO₂), with each ton of biochar offsetting around 1.8 tons of CO₂. Since the biochar market in Thailand is still developing, the project relies on selling carbon credits through the Puro.Earth platform to sustain operations. Beyond environmental benefits, the project aligns with global sustainability goals by creating jobs, reducing air pollution-related health risks, and promoting sustainable agriculture. Enable Earth is working closely with local communities, government agencies, and researchers to ensure long-term success. Once proven, the model could expand to other provinces and neighbouring countries, scaling its positive impact on climate and agriculture.

SCG Cement is a leading company in the construction materials industry, operating the largest cement and concrete production facilities throughout Thailand. We are dedicated to ESG principles, striving to produce environmentally friendly products and services with the lowest carbon emissions. In our pursuit of innovation, we have developed advanced biomass refinery technology aimed at creating a circular economy for Thai farmers. We have established the country's largest pyrolysis plant, which converts agricultural waste into biochar. 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.

Project Backyard marks Woodcache PBC's flagship commercial venture, and we are thrilled to launch this transformative operation in Southern Colorado, a region we’ve had the privilege to work with closely. Over the next five years, Project Backyard aims to remove more than 100,000 metric tonnes of liability biomass from forest floors and remove approximately 130,000 metric tonnes of CO2 from our atmosphere. The wood we remove is not just debris, but a liability that can contribute to catastrophic wildfires that threaten the American West. By sourcing this high-risk biomass and securely storing it in specially designed geologic vaults, we prevent it from decaying or burning and releasing carbon back into the atmosphere. This process ensures that the carbon remains locked away for centuries, mitigating the threat of wildfires and reducing greenhouse gas emissions. Beyond carbon removal, Project Backyard is a holistic approach to wildfire risk reduction that benefits local communities and rural life. It safeguards biodiversity, preserves watershed and stream health, and protects human well-being. Wildfires don’t just destroy landscapes they pollute air and water and unleash vast amounts of greenhouse gases, exacerbating climate change. Through Project Backyard, we’re addressing these interconnected challenges head-on, creating a safer, healthier, and more resilient future for our communities and ecosystems.

In July 2024 we at Exomad Green launched our second biochar facility in Riberalta, Bolivia. We expect to scale up our operations significantly during 2025. This facility will leverage the power of biochar to sequester up to 120,000 tons of CO2 annually. But our vision goes beyond environmental impact. Exomad Green is about creating a better, more sustainable world for everyone. We're striving to improve the quality of life for over 250,000 regional inhabitants, generate green jobs, foster local economic growth, and champion environmental justice across the region. Join us as we embark on this transformative journey, turning residues into wealth and cultivating a more sustainable future. Our process begins at the source with the collection of biomass residues from local sawmills, providing us with an abundant, renewable source of biomass. The biomass is then transported to our state-of-the-art pyrolysis plant, where it undergoes a meticulous sorting and pre-treatment process that includes pre-drying and grinding, using energy-efficient machinery. The biomass is then subjected to pyrolysis at approximately 600 degrees Celsius, during which the carbon in the biomass is trapped, preventing it from being released as carbon dioxide. This results in the production of biochar, a rich carbon product with a unique honeycomb-like structure, ideal for soil enhancement. The biochar we produce improves soil fertility by increasing its capacity to retain water and nutrients, enhancing microbial activity, regulating soil pH, and aiding in soil remediation by absorbing toxins and heavy metals. We then donate our biochar to local indigenous communities, empowering them to enhance their agricultural yields. By doing so, we not only support their livelihoods but also actively contribute to reducing deforestation, ensuring the preservation and sustainable use of our invaluable South American forests. But the benefits of our project do not stop at soil improvement for the local communities. Exomad Green is committed to exceeding environmental standards. We adhere strictly to local and national regulations and have implemented a water treatment plan, enabling us to recycle and reuse water within the plant. We also employ a system for the effective capture and utilization of bio-oil and syngas by-products of the pyrolysis process, further minimizing our environmental footprint. By leveraging the pyrolysis process, we ensure that more than 70% of the heat generated is reused, further boosting our energy efficiency. The syngas produced during pyrolysis is also captured and used as a source of energy within the plant, reducing our reliance on external energy sources. Through our operations, we not only reduce air pollution and fire risks associated with the improper disposal or incineration of biomass residues but also aim to improve air quality for around 250,000 people. We're proud to be contributing to an environmentally friendly solution that simultaneously improves community health. In terms of social impact, we are currently creating green tech jobs for the community, with approximately 50 direct and 200 indirect employments. But we aim to triple this numbers by 2025. We comply with all local and national regulations regarding insurance and social benefits for our employees, providing dignified, sustainable employment. Exomad Green's Sustainable Biochar Project is a shining example of a circular economy model that addresses multiple environmental challenges. The project embodies the true essence of sustainability, combining economic viability with environmental responsibility and social equity. Examples of usage info Biochar, a product of pyrolysis, has the ability to sequester carbon dioxide (CO2) because of the nature of its production process and the properties of the resulting material. Here's how the sequestered CO2 in biochar is used or stored: Carbon Capture during Production: During the pyrolysis process, organic matter is heated in an oxygen-limited environment. This prevents the full decomposition of the organic matter into CO2 and other gases. Instead, a significant portion of the carbon in the biomass is retained in a stable form within the biochar. Stable Carbon Structure: Biochar is mostly composed of carbon in a very stable form. This means that it doesn't easily decompose or oxidize to release CO2 back into the atmosphere. As a result, when biochar is applied to soil, the carbon it contains remains sequestered in that stable form for a very long time—potentially hundreds to thousands of years. Soil Application: When biochar is incorporated into the soil, it essentially locks away the carbon it contains. In other words, the carbon in the biochar is removed from the short-term carbon cycle because it won't be quickly returned to the atmosphere as CO2. Enhancement of Soil Carbon Storage: Biochar addition to soils can also indirectly lead to increased soil organic carbon levels by promoting the microbial processes that incorporate CO2 from the atmosphere into soil organic matter. Reduction of Greenhouse Gas Emissions: In addition to its carbon storage capabilities, biochar has been found to reduce the emissions of other greenhouse gases from soil, notably nitrous oxide (N2O). It can do this by influencing soil microbial processes. Displacement of Fossil Fuel Carbon: The pyrolysis process that produces biochar also generates bio-oil and syngas, both of which are used as energy sources. By utilizing these renewable energy sources instead of fossil fuels, there's a reduction in the net CO2 added to the atmosphere.

Green Hub 1 is the first project among a series of pyrolysis projects to be developed in the UK that will pyrolyse problematic waste biomass into biochar and green energy while sequestering carbon. The Green Hub series aims to deliver positive climate action through carbon removal, regenerative agriculture, green energy generation and curbing pollution. Located in Herefordshire, the project will target different streams waste biomass that are a potential threat to the environment. The green and arboricultural waste streams (like grass clippings, tree branches, and leaves) emit significant methane and CO2 emissions from current disposal methods like landfills, composting and anaerobic digestion. Furthermore, seasonal surges in green waste can overwhelm composting facilities, leading to inefficiencies, slower processing, and contamination of the compost, further reducing its quality. Some of these waste biomass streams are stored and directly applied on land, leading to polluted run-offs entering the river Wye, causing algal blooms and threatening the eco-system. Onnu has developed a unique pyrolysis machine in partnership with engineering firm Woodtek that will pyrolyse these different waste biomass streams. With a vertical design, the scalable C1000 can effectively pyrolyse huge quantities waste biomass and convert it into biochar, a stable, carbon-rich material which locks away the carbon rather than releasing it back into the atmosphere. The syngas released from the process is combusted to generate green energy. A robust emissions scrubber with a Continuous Emissions Monitoring System (CEMS) ensures that no harmful gases are released into the atmosphere. The entire pyrolysis unit is fully automated with user-friendly HMI that aids in effective monitoring, tracking and controlling of the system to achieve maximum positive outcomes. The biochar produced from the process is a highly effective soil additive that can promote water and nutrient retention. Enhancing microbial activity while balancing the soil pH, it is crucial in implementing regenerative agricultural practices in the region. The excess heat energy left after satisfying the unit’s self-sufficiency and drying requirements is converted into green electricity, which is being utilized for powering data centres running gen-AI tasks.

Future facility
North Star is a Bioenergy with Carbon Capture and Storage (BECCS) carbon removal project located in Meadow Lake, Saskatchewan, Canada. The new carbon capture and storage (CCS) facility will capture biogenic emissions from the existing MLTC Bioenergy Centre, which currently produces renewable heat and power from waste generated by the NorSask Forest Products sawmill. The biomass that feeds the sawmill is sustainably harvested and managed. The captured biogenic CO2 will be transported via pipeline to a nearby geological storage site where it will be injected for permanent storage into the Basal Cambrian Sandstone formation. The entire CCS process will be operated by Carbon Alpha and co-owned with Meadow Lake Tribal Council, who represent 9 First Nations in NW Saskatchewan. The project is currently in the design phase and is planned to be operational by mid-2027. Approximately 70,000 CORCs will be available annually once the project is operational.

Founded in Australia in 2005, the Fasera Group is a leader in sustainable agricultural carbon sequestration through our managed estates of Australian oil mallees and other eucalypt species to produce: • Eucalyptus oil • Carbon Dioxide Removal Certificates (CORCs) & Australian Carbon Credit Units (ACCUs) • Biochar; • Wood vinegar (a natural herbicide and bio-stimulant). Our plantations include thousands of hectares of mature mallee trees. Historically, these were difficult and costly to harvest using traditional forestry methods. Fasera has invested in innovative new harvest techniques and equipment, enabling us to harvest mature mallees much more cost-effectively and significantly increasing our oil mallee resources. The development of coppice regrowth – the increased regrowth of mallee tree biomass after each harvest - has been established as most effective for long term carbon sequestration. Shearing the trunk at ground level, encourages coppice regrowth leading to increased biomass growth, generating an unending cycle of increasing harvests. This process also results in considerably higher levels of carbon sequestration than if individual trees were left to mature, where carbon retention capacity peaks and then stabilises. The expansion of Fasera’s mallee oil processing facility and product range continued with the commissioning of a continuous pyrolysis plant in 2022. The plant is co-located with our oil distillery; it processes the spent mallee biomass remaining after the steam distillation to produce eucalyptus oil. At capacity, it will pyrolyse up to 5,000 tonnes of spent biomass to produce about 5,000 m3 of biochar per annum. The heat from the process is recycled and used in the steam distillation process. The biochar produced is distributed locally as a soil amendment and in ingredient in ruminant animal feed. Fasera has just completed filling and sealing our first Terrestrial Storage of Biomass chamber on our Canterbury Farm, Kulja, Western Australia. This chamber will generate CORCs under the PURO methodology and is the first chamber at site with the potential to generate 100,000 CORCs. www.fasera.com
