Isometric has certified its new module for storing biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More in built materials, a development poised to advance the market for high-integrity carbon dioxide removal (CDR) credits. This certification, which followed a 30-day public consultation period, validates a new method for permanent carbon storage by incorporating biochar into construction materials such as concrete and asphalt.

Biochar is created through pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More, the process of heating biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More in a low-oxygen environment. This process transforms the biomass into a stable, carbon-rich material that effectively sequesters CO2 that would otherwise be released into the atmosphere. The new Isometric module focuses on one of many possible next steps: utilizing this biochar as an additive in construction materials. This approach provides a method for durable carbon storage, with Isometric’s assessment indicating a durability period of 1,000 years, a key metric for long-term climate solutions. Biochar has been touted as an incredibly stable carbon removal solution, so this standardization, even if it comes with more empirical rigour, is a positive step for biochar’s position in carbon markets.

To achieve this certification, Isometric employed a comprehensive monitoring, reporting, and verification (MRV) framework. The module mandates rigorous requirements for biochar characterization and continuous monitoring of the final product. It also includes a detailed risk analysis over the 1,000-year timeframe, considering potential damages during the product’s use, demolition, and subsequent recycling.

CDR suppliers seeking to utilize this module must provide extensive documentation on their production processes and the performance of the end product. The module was developed by Isometric’s Science Team in collaboration with over 300 experts from their Independent Science Network and incorporated feedback from key industry players. This certification marks a significant step forward in recognizing and standardizing the durable carbon storage potential of biochar-based construction materials within the broader sustainability sector.
