Abstract
A method for producing biochar aggregate particles that comprising the steps of (i) collecting or producing treated biochar fines less than 1 mm, (ii) adding a binding agent to the fines, (iii) forming the fines and binding agent into solid aggregate particles. The steps may further include, for example, adding additives to the fines, drying the solid aggregate particles, activing the binder after forming the solid aggregate particles with heat or cold temperatures and/or treating the biochar fines prior to forming the aggregate particles.
