Waste Treatment: the AD/Slow Pyrolysis Integrated Route for Biomethane, Ammonium Sulphate and Biochar to Store&use Carbon in EU MED Soils
Short Introductive summary
The integration of Anaerobic Digestion (AD) of biowastes, Slow Pyrolysis (SP) of digestates and CO2 liquefaction of biowaste enables to achieve full carbon recovery, producing Biomethane, CO2, storing ~70% of the remaining carbon in a stable carbon-rich soil form, and using it as a soil amendment. This approach represents a new circular solution fully integrated in the existing waste treatment, which is accounts for more than 1900 plants in Italy only. RE-CORD studied a full industrial scale AD/SP integrated system processing 40,000 t/y of biowaste to produce biomethane, liquid CO2, biochar and ammonium sulphate in Tuscany, on a real industrial initiative developed by waste treatment company in Tuscany. This work focuses on the design and experimental validation of the plant thermochemical treatment section, where the biowaste digestate is processed by SP to produce biochar and recover ammonium sulphate, as describe in the following scheme.
