The increase in global energy demand, the decrease of fossil resources, and local and global environmental issues push to investigate new sustainable technologies to increase the production and use of alternative fuels. For being competitive on the market, biofuels require to have a production cost comparable to those of traditional fuels. The cost of the organic feedstock material often accounts for more than a third on the total production cost, therefore the use of waste organic fractions as feedstock to produce substitute fuels allows increasing the overall efficiency of their production process. This perfectly matches the political pressure in increasing recycling rates, valorizing waste fractions and the general idea of creating a more circular economy.
Considering the above aspects, the current study is aimed to investigate the potential of the Hydrothermal Liquefaction (HTL) technology when processing waste plastics, and organic waste sources as manure and wastewater cultivated willow. HTL is a thermochemical process which is capable of converting various carbon sources into a biocrude product, a sustainable fossil crude substitute which consists of highly valuable chemical compounds.
Linking together the environmental benefits, deriving from the utilization of waste sources, with the production of biofuels and chemicals, it provides double advantages.
