Abstract

The hydrochar (HC) produced from the hydrothermal carbonisation at mild temperature (190-220°C) of several typologies of organic wet waste, among which agro-industrial waste, seems very promising as amendment/fertilizer. The aerobic post-treatment of HC improves its agronomic properties (Bona et al., 2022). The project “HYDRORG” founded by VRT (Fondazione Valorizzazione Ricerca Trentina) studied the agro-environmental properties and effect on soil of HC compared to compost (COM) and HC aerobically post treated (MIX) (Bona et al., 2023).
