What is pyrolysis?
The production of biochar involves three different steps:
The purpose of the pre-treatment is to process the organic material so that the pyrolysis is as effective as possible. In most cases, this involves dewatering and drying the material in cases where the material has a high water content (sludge, algae and seaweed). Another type of pre-treatment is cleaning and sifting to remove stones and gravel that could otherwise destroy the feed screws and other parts of the pyrolysis boiler.
