プロジェクト概要
The INTERHOLCO AG (IHC) project converts sawmill wood waste into biochar to create durable carbon sinks in the Republic of Congo. Located at the sawmill site in Ngombé, Ouesso Region, the project replaces open-air burning of residues with controlled pyrolysis and applies the resulting biochar to tropical soils and sealed chambers in former laterite pits, enabling long-lived carbon storage. The project is certified under the European Biochar Certificate (EBC) standard and follows Carbon Standards International (CSI) procedures for monitoring and registry listing.
Feedstock consists of wood waste from sustainably managed, certification-backed forest operations, and the biochar is currently used only for carbon sink applications, including rehabilitating old or abandoned forest roads and serving as a geological sink in laterite pits via a chamber method that prevents reuse. The project deploys a digital monitoring, reporting, and verification (dMRV) tool (CULA), endorsed by CSI and connected to the global registry via API, to track batches, locations, and parameters from production to final sink.
The project developer operates long-running sawmill and forest concessions in the area with third-party certifications, a workforce of over 1,000, and reported community services including healthcare, education, and basic utilities. Given the lack of a local biochar market and high export costs, carbon credits are the project’s decisive revenue stream and are reinvested to expand production capacity, logistics, and application.
