The Biochar Handbook: A Practical Guide to Making and Using Bioactivated Charcoal

“A brief yet thorough introduction to the history, science, and practicalities of biochar-making and its tremendous potential to restore degraded soils. Highly recommended.” —David R. Montgomery, author of Dirt and Growing a Revolution “This book is an absolute tour de force. It answers so many commonly asked questions about biochar in easy-to-understand prose. Everyone from newbies to those who have been in the biochar industry for years will learn a lot from reading this book. Recipes for bokashi, compost, toothpaste, and more showcase how biochar can be used both inside and outside the home.” —Kathleen Draper, coauthor of Burn; former International Biochar Initiative Board Chair “Climate repair is the greatest challenge we have ever confronted, and it falls upon our generation, right now, no excuses. A formidable scholar and mechanical engineer, Kelpie Wilson has a way with words that few with either of those skills can equal. I would read her just to enjoy her style and humor, even if the subject were not so urgent and the stakes so astronomical.” —Albert Bates, 2024 EcoHero of the Year; author of The Paris Agreement and The Biochar Solution; coauthor of Burn “Finally! A book on biochar that is not merely evangelizing, but written by someone with experience, who has read and done the research in order to learn the actual facts about what biochar is, what it does, and how it can be used at any scale of agriculture. It’s good to see this subject finally addressed in a practical, no-nonsense way. Thumbs up!” —Mark Shepard, author of Restoration Agriculture and Water for Any Farm “A balanced, intelligent, and practical guide to one of the most promising ventures in the modern appropriate technology scene, Kelpie Wilson’s book shows its author’s detailed knowledge and extensive experience with biochar on every page. I would not be at all surprised to see The Biochar Handbook turn into the classic text in this burgeoning field.” —John Michael Greer, author of Green Wizardry and The Druid Path “This is by far the best book on biochar I’ve ever seen! We’ve all been needing this book—it’s scientifically rigorous, well-written, and highly visual. If you don’t have it already, get yourself a copy today!” —Matt Powers, author of The Regenerative Soil Trilogy
