Described herein is a method of carbonizing organic waste to produce a stable form of biocarbon for the purposes of carbon sequestration. In some embodiments, the method is a continuous method wherein organic waste is added at a top of a carbonization system and biocarbon is recovered from a bottom thereof.

In a method for producing pyrolysis oil, pyrolysis gas and pyrolysis coke, a starting material substantially comprising biomass is supplied to the upper region of a pyrolysis reactor. The latter has a substantially vertically arranged reactor chamber, which is substantially tubular. The reaction chamber then contains a bed of bulk material that comprises the starting material to be pyrolyzed and, optionally, the pyrolysis coke. This bulk material is thermally treated in the pyrolysis reactor, where the pyrolysis coke, the pyrolysis gases and the pyrolysis vapors are formed from the starting material to be pyrolyzed, and where the bulk material, the pyrolysis gases and the pyrolysis vapors are guided through the reaction chamber from top to bottom. The movement of the bulk material is caused substantially by gravity and the movement of the pyrolysis gases and pyrolysis vapors by the gas pressure building up.
