Future Policy Directions for Biochar Carbon Removal

Cathy Wang • November 12, 2025

As the world grapples with the escalating impacts of climate change, biochar, a form of carbon sequestration, has garnered attention for its potential role in mitigating greenhouse gas emissions. Biochar is produced through the pyrolysis of biomass, resulting in a stable form of carbon that can be stored in soils for centuries. The increasing focus on carbon removal technologies (CDR) has led to discussions about the role of biochar in future environmental policies. This article explores potential policy directions for biochar carbon removal, highlighting the key factors that could shape its future regulatory and market landscape.

Growing Policy Support for Carbon Removal Technologies

The importance of carbon removal technologies is becoming more apparent as governments worldwide aim to achieve net-zero emissions by mid-century. Policies are gradually evolving to incentivize methods like direct air capture (DAC), afforestation, and biochar production equipment. Governments and international organizations are expected to implement stronger regulatory frameworks to support CDR technologies, including biochar.

In the context of biochar, a major driving force for future policies will be the potential for carbon credit systems and emissions trading. Carbon credits offer a financial mechanism to reward companies and projects that capture and store carbon, making biochar production economically attractive. If biochar is certified as an effective method of carbon removal, it could be integrated into carbon markets, where it can be traded as a verified credit, ensuring the long-term viability of biochar production.

Establishing Standardized Carbon Accounting

For biochar to be recognized as a legitimate method of carbon removal, robust systems for measuring, reporting, and verifying carbon sequestration will be crucial. One of the challenges currently facing biochar production is the lack of standardized protocols to accurately assess how much carbon remains stored in biochar over time. As a result, policy frameworks in the future will likely focus on the development of clear standards for biochar carbon accounting.

These standards will help policymakers determine the efficacy of biochar projects, ensuring that the carbon sequestration claims are credible and transparent. Governments may also fund research into improving the methods for monitoring biochar's longevity in soils, factoring in the environmental conditions that influence its persistence and effectiveness. Without these standardized accounting frameworks, biochar risks being overlooked as a viable solution for large-scale carbon removal.

Integration with Circular Economy Models

Biochar’s role in the circular economy is another aspect that could shape future policies. By transforming waste biomass into valuable products like biochar, the biomass pyrolysis plant model promotes resource efficiency. This aligns with growing global interest in circular economy principles, which prioritize the reduction of waste and the recycling of materials into new uses. Biochar fits neatly within this framework by providing a sustainable outlet for agricultural and industrial residues, while simultaneously sequestering carbon.

Policymakers may create incentives for businesses that incorporate biochar into their operations or manufacturing processes, whether for agricultural applications, waste management, or energy generation. These incentives could drive further investment in pyrolysis plant technologies and create a more favorable market environment for biochar as a carbon removal strategy.

Policy Incentives for Sustainable Biomass Feedstocks

The sustainability of feedstocks used in biochar production will be another focus of future policy initiatives. Biomass used for biochar is typically derived from agricultural residues, forestry waste, or dedicated crops. Ensuring that the feedstocks are sourced sustainably is critical to the environmental integrity of biochar projects. Policies that govern biochar carbon removal will likely include guidelines for sourcing biomass in ways that do not result in deforestation, land degradation, or food insecurity.

In some regions, policymakers may offer financial incentives for the use of waste biomass or low-value materials, further promoting the environmental benefits of biochar. As the demand for biomass feedstocks increases, careful management of land use and agricultural practices will be essential to prevent negative environmental impacts.

Long-Term Carbon Storage and Soil Health Regulations

Biochar’s ability to store carbon in soils for hundreds to thousands of years makes it a unique solution in the fight against climate change. However, policies must also address its potential benefits for soil health and agricultural productivity. The long-term storage of carbon in soils could contribute to improved soil fertility, water retention, and microbial activity, all of which have implications for sustainable farming practices.

Future regulatory frameworks are likely to incorporate soil health considerations into biochar policies, encouraging its use as a soil amendment. Policies may promote biochar applications that improve soil quality, especially in degraded lands or areas where conventional farming practices have led to soil erosion and nutrient depletion. Governments could incentivize the use of biochar by integrating it into programs focused on sustainable agriculture or land restoration.

Alignment with Climate Goals

As biochar technology continues to evolve, its potential to contribute to global climate goals will become more evident. Governments will likely align biochar production with national and international climate targets, such as the Paris Agreement’s aim to limit global warming to well below 2°C. Biochar could play a role in achieving carbon neutrality by offsetting a portion of a country’s emissions, making it an attractive component of climate action plans.

In addition to carbon removal, biochar can contribute to other sustainable development goals (SDGs), such as reducing waste and promoting sustainable agriculture. As such, biochar production may find its place within a broader environmental policy framework that emphasizes circular economies, waste-to-value initiatives, and soil conservation.

Path Forward: Comprehensive Policy Frameworks for Biochar

Looking ahead, biochar's potential as a carbon removal technology will largely depend on the development of comprehensive and cohesive policy frameworks that support its production and application. As biochar moves from a niche technology to a mainstream solution, governments must ensure that environmental, economic, and social considerations are integrated into the policy development process. With proper regulation, incentives, and research, biochar could emerge as a key player in the global effort to combat climate change and build a more sustainable future.

Emerging Growth Potential of Tire Pyrolysis Projects in Africa

By Cathy Wang • November 24, 2025
Africa is witnessing a rapid surge in urbanization, motorization, and industrial expansion, which collectively generate unprecedented volumes of end-of-life tires. With limited landfill space and growing pressure to curb uncontrolled dumping and open-air burning, the region has begun turning toward technologically viable resource-recovery solutions. Among these, a modern pyrolysis plant has emerged as a strategic asset. It converts discarded tires into pyrolysis oil, carbon black, steel wire, and combustible gas—products with strong commercial traction in both local and export markets. The scale of tire accumulation, combined with new environmental regulations, positions tire pyrolysis plant as a timely and profitable sector across the continent. Robust Availability of Feedstock End-of-life tires are abundant in Africa due to aging vehicle fleets, limited recycling infrastructure, and low entry barriers for imported second-hand tires. In nations such as Nigeria, Kenya, South Africa, Ghana, and Tanzania, millions of tires are discarded each year. This stable and inexpensive input stream offers a significant economic advantage. Key Advantages Minimal competition for feedstock supply Lower collection costs compared with developed markets Presence of informal waste aggregators who support continuous sourcing Such conditions create long-term predictability for project developers seeking secure supply chains.

Thermal Desorption for Oil Contaminated Soil Remediation

By Cathy Wang • November 18, 2025
The management of oil-contaminated soil has become a critical environmental issue, particularly in areas affected by industrial operations, spills, and accidental discharges. Traditional soil remediation techniques often fall short in terms of efficiency, environmental impact, and cost-effectiveness. In contrast, thermal desorption presents a viable solution for addressing these challenges, offering a range of benefits in the restoration of contaminated sites. By utilizing a thermal desorption unit, the removal of oil contaminants from soil can be achieved effectively, ensuring a cleaner, safer environment and compliance with environmental regulations. Efficient Removal of Oil Contaminants One of the primary advantages of using a thermal desorption unit in the remediation of oil-contaminated soil is its efficiency in removing organic pollutants, particularly oils and hydrocarbons. The thermal desorption process involves the application of heat to soil, causing volatile contaminants, including oils, to vaporize. These contaminants are then captured, condensed, and separated from the soil, effectively purging the material of harmful substances. This method is particularly effective for dealing with soils contaminated by petroleum-based products, such as crude oil, diesel, and lubricating oils. It is ideal for large-scale cleanup operations where time is a crucial factor, as thermal desorption can process significant volumes of contaminated soil in a relatively short period. The precision and speed of this process ensure that oil residues are removed from deep within the soil matrix, something that traditional methods, such as bioremediation, may struggle to achieve.

What Makes Char “Biochar”? Understanding the Conditions Behind Its Production

By Cathy Wang • November 11, 2025
Biochar has gained significant attention in recent years as a sustainable tool for soil improvement, carbon sequestration, and even renewable energy. But not all charcoal is considered biochar. The key lies in the conditions under which it is produced. Defining Biochar Biochar is a stable, carbon-rich material derived from biomass—such as agricultural residues, wood chips, or forestry waste—through a process called pyrolysis. Unlike ordinary charcoal used for cooking or fuel, biochar is specifically produced with environmental and agricultural benefits in mind. The Critical Conditions for Biochar Production 1. Temperature Control Biochar is typically produced at moderate pyrolysis temperatures, generally between 300°C and 700°C. Lower temperatures (under 300°C) may produce materials that are too volatile or unstable, while excessively high temperatures (over 700°C) can reduce the material’s nutrient content and adsorption capacity. 2. Limited Oxygen Environment To prevent complete combustion, pyrolysis must occur in an oxygen-limited or anaerobic environment. This ensures that the biomass carbon is retained in solid form, rather than being released as CO₂ or other gases. 3. Controlled Heating Rate The speed at which the biomass is heated affects the properties of the final biochar. Slow pyrolysis generally yields a higher fraction of solid biochar, whereas fast pyrolysis produces more liquid bio-oil and syngas. You can get some information in the biochar pyrolysis machine . 4. Biomass Quality The feedstock matters. Agricultural residues, wood, and organic waste are commonly used. Certain feedstocks may result in biochar with higher nutrient content or better soil amendment properties. Why These Conditions Matter The controlled production conditions ensure that the resulting biochar has the stability, porosity, and nutrient content necessary to improve soil fertility, retain water, and sequester carbon for long periods. Char produced under uncontrolled burning, such as forest fires or cooking fires, usually does not qualify as biochar because it lacks these beneficial properties. Conclusion In essence, not all charcoal is biochar. True biochar comes from biomass processed under controlled, oxygen-limited conditions at moderate temperatures, with a careful choice of feedstock and heating method. These conditions create a carbon-rich, stable material capable of delivering environmental, agricultural, and climate benefits.
