Abstract

The invention provides a continuous charcoal manufacturing apparatus for turning particulate organic material into charcoal. The apparatus comprises a source of the particulate organic material, a retort and a heating device for heating gas in an external vessel interior space. The source of the particulate organic material comprises an outlet for discharging the particulate organic material from said source! The retort has an external vessel and an inner vessel within the external vessel, whereby the walls of the two vessels are spaced apart from each other so as to define the external vessel interior space between the walls. The external vessel ulterior space is coupled to the source of the particulate organic material so as to allow gases to pass from said space to the source and the inner vessel has an inlet coupled to the source through which the particulate organic material can pass and an outlet for allowing the charcoal to exit the inner vessel.

Abstract

The invention relates to a biochar-containing composition comprising biochar having organic matter therein and/or thereon, clay associated, optionally intercalated, with the organic matter, a non-clay mineral and optionally also a plant growth promoter.
