DESCRIPTION OF THE OFFER

Energy valorization of organic waste by hydrothermal co-carbonization and anaerobic digestion

Hydrothermal carbonization (HTC) is an emerging and environmentally friendly thermochemical technology used to upgrade solid fuel properties of wet biomass. The product obtained from HTC is a slurry that can be efficiently dewatered by mechanical compression to obtain a hydrophobic hydrochar (HC) with added value as a lignite-alike coal for combustión. Additionally, the dewatering of HTC slurry produces a process water (PW) with high organic matter concentration due to the significant content of hydrocarbons with high molecular weight. Furthermore, the PW is characterised for significant content of total Kjeldahl nitrogen, phosphate, and some heavy metals. Based on the aforementioned characteristics, the PW can be valorized via anaerobic digestión.

To improve the characteristics of the hydrochar a co-carbonization process mixing different biomass can be carried out. The proposal of this TFM is carry out co-carbonization of swine manure and pruning waste, to obtain a high quality hydrochar and a process water susceptible of valorisation by anaerobic digestión.
