The International Organization for Standardization (ISO), the world's largest developer and publisher of international standards, with a network of national standards bodies from 172 countries, has expanded into the standardization of biochar and biocarbon. This effort will be led by the newly reformed Technical Committee (TC) 238 on Solid Biofuels and Pyrogenic Biocarbon.

International standards play a central role in enabling and supporting the development of emerging industries and new markets. They help dismantle international trade barriers, enabling companies to compete globally by adhering to consistent, high-quality benchmarks. Standards ensure fair competition, support safe industry scaling, and foster sustainable growth. Furthermore, standardization facilitates the integration of scientific knowledge into industry practices. Additionally, participating in standards development offers invaluable networking opportunities by connecting with industry experts worldwide.

Broader Scope of TC238

The updated scope of TC238 covers a wide range of thermally treated biomasses from various processes—including slow pyrolysis, torrefaction, hydrothermal carbonization, and gasification—resulting in products such as biochar, biocarbon, and bio-coal. These products are collectively referred to as pyrogenic biocarbon.

ISO has officially approved the revised title and scope of TC238: Solid Biofuels and Pyrogenic Biocarbon

Standardization of terminology, specifications and classes, sampling and sample preparation,test methods, and safety aspects in the field of raw and processed materials originating from arboriculture, agriculture, aquaculture, horticulture and forestry to be used as a source of thermally and non-thermally treated solid biofuels and pyrogenic biocarbon.

Progress So Far

Following a proposal from Canada in 2021, ISO TC238 formed a task group on biocarbon to assess global market needs for new or expanded biocarbon standards. Since then, the task group has engaged with a wide range of stakeholders, including biochar producers, end users, industry associations, policymakers, researchers, and laboratories specializing in pyrogenic biocarbons. The task group has also developed a strategic roadmap for pyrogenic biocarbon standardization. Based on the work, it was evident that the global market for pyrogenic biocarbon is expanding rapidly, highlighting the urgent need for international industry standards. This growing interest in standardization is evident in the task group itself, which now includes 57 participants from 14 countries (Austria, Canada, China, Finland, France, Germany, India, Italy, Japan, Netherlands, Spain, Sweden, UK, U.S.A.)

What’s Next?

The technical committee’s initial work will focus on developing terminology and classifications for different pyrogenic biocarbons, such as biochar, biocoal, and biocarbon. The first tasks are expected to establish clear classifications and define key characteristics of various types of biocarbons to help differentiate these products in the markets. Ultimately, the standardization efforts will be driven by market and industry needs.

How to Get Involved

Industry experts are encouraged to participate in developing pyrogenic biocarbon standards. When implemented, ISO standards are known to have a significant impact on international markets, and participating in the technical committee is an excellent opportunity to participate and keep up with the development.
