INTRODUCTION

Biochar is a carbon-rich material that is made from biomass through a thermo chemical conversion process known as pyrolysis.

When it comes to building a circular economy, every kind of waste is either eliminated or recycled into new valuable materials. But waste comes in all shapes and sizes—there’s no single “magic bullet” for addressing every different kind. That’s why scientists and policymakers call for a diversity of tools and solutions for achieving sustainable economies and societies. To understand biochar, it’s worth appreciating a specific form of waste—organic waste—and the problems it poses from a sustainability perspective.

The most common types of organic waste that we encounter in our day-to-day lives are food waste, yard trimmings and clippings, and—hold your nose—sewage. While these are each different in terms of material composition and life cycle (how they are made and disposed of), they tend to present similar challenges (and, as we’ll see, opportunities).

Loosely understood, any material that is immediately derived from plants and animals is organic. Another common term for this is biomass. Sometimes the term “biodegradable” is used to describe biomass as waste because it can be broken down into organic molecules by microscopic living things like bacteria, fungi, and microbes.

Most everything, from an old cookie to a car axle, eventually breaks down under the right conditions and with enough time. But organic materials break down much faster than inorganic ones do. Because of the fast pace with which organic matter decomposes, it presents unique challenges when it comes to mitigating its environmental impacts as waste.

When biomass degrades in a landfill or a treatment center, the potent greenhouse gases (GHGs) carbon dioxide and methane are released, among others. Methane is twenty times more potent than carbon dioxide as a greenhouse gas, though carbon dioxide remains in the atmosphere for much longer.
