Sustainable Hydrothermal Carbonisation of Industrial Olive Pomace Using Inherent Water Content to Produce Hydrochar for Fuel Application

Short Introductive summary

In the olive oil industry, processing an olive fruit produces 20% oil and 80% olive pomace (OP) as a residue. Management of OP is challenging due to the presence of very high-water content (60-80%) and toxic phenolic compounds. It is an abundantly available lignocellulosic biomass in the European Union, and its valorisation can promote the sustainable development, bioeconomy and a clean environment. The present study investigated the direct sub-critical hydrothermal carbonisation (HTC) of OP for hydrochar production in order to take advantage of its inherent high-water content and obviate the need for any intermediary steps like drying. The impact of HTC conditions (180–250°C temperature, 2–30 min holding time) on hydrochar characteristics was investigated. The hydrochar produced at 250°C showed better fuel properties, i.e., lesser ash content (2.78–3.52%), higher fuel ratio (0.37–0.40), and HHV (19.18–19.54 MJ/kg). Therefore, the present study found this OP hydrochar to have more potential for fuel application.
