METHOD FOR PRODUCING ORGANO-MINERAL FERTILIZER BY HYDROTHERMAL CARBONISATION OF SUGARCANE VINASSE AND BAGASSE AND THUS OBTAINED PRODUCT

摘要

The invention relates to a method for producing a water-retaining, organo-mineral fertilizer by hydrothermal carbonisation of sugarcane vinasse and bagasse, using an acid catalyst, preferably phosphoric acid, in a hydrothermal carbonisation method, adding value to these wastes and enabling their use within the production cycle, reducing the cost of transport, fertilizers and chemical treatments, inter alia.
