In the previous modules, you learned how to operate and maintain biochar production systems safely and efficiently. In Module 6, the focus shifts to quality—how production conditions, testing procedures, and handling practices influence the characteristics, consistency, and value of the final biochar product.

Throughout this module, you'll explore the key factors that affect biochar quality, from tar formation and process control to sampling methods, laboratory analysis, and product storage. You'll learn how to evaluate biochar against industry standards, interpret quality data, and apply best practices that ensure product integrity from production through delivery. By understanding these principles, you'll be better equipped to produce a reliable, high-quality biochar that meets customer expectations and certification requirements.

Each section also includes downloadable supporting resources and a full video transcript, which participants may use for reference, note-taking, or translation into their preferred language if needed.
