International Biochar Initiative Implications and Risks of Potential Dioxin Presence in Biochar

The International Biochar Initiative (IBI) is a non-governmental organization (ngo) that promotes the development of biochar systems that follow Cradle-to-Cradle sustainability guidelines. As a new industry, it is important that systems for biochar production and use be analyzed and monitored for environmental impact and sustainability. Biochar systems analysis begins with complete characterization of biochar materials, and IBI has published Standardized Product Definition and Product Testing Guidelines for Biochar That Is Used in Soil (hereinafter referred to as Biochar Standards and Testing Guidelines) that provide a consistent framework for measuring and reporting essential biochar properties (physical and chemical), as well as determining whether any contaminants are present in a biochar material.
