Hydrothermal liquefaction of food wastes for sustainable production of high-grade biocrude-oil to drop-in transport fuel

The transport sector is the highest consumer of fossil fuels accounting for 96% of the global energy, which corresponds to 65% of the global crude oil consumption. The escalating consumption of fossil fuels causes harmful environmental pollution by releasing > 7 billion tons of CO2 into the atmosphere. The awareness to transition from conventional fossil fuel to eco-friendly options has resulted in several decarbonization strategies with Europe’s priority to develop new alternative and carbon-neutral energy sources based on a cost-effective biomass-based thermochemical conversion. Hence, the objective of CO-HTL4BIO-OIL is to develop commercially viable catalytic co-hydrothermal liquefaction (CO-HTL) that converts 2G wet solid food wastes into a sustainable transport fuel with potential 100% atom efficiency, low production costs, and zero CO2 emissions. An in-depth study on the HTL parameters, optimization of the CO-HTL process, and techno-economic assessment are expected to provide an outlook scenario of the industrial-scale process for high biofuels production capacity. The project will respond to the Renewable Energy Directive (RED, 2009/28/EC) targeting-20-20-20 by 2020: 20% reduction in greenhouse gas emissions, 20% increase in energy efficiency, and 20% of the EU’s energy consumption originating from renewable sources. Hence, it will have a positive and pioneering impact in bringing together Europe's knowledge-based economy and society toward sustainable and green transportation.
