Sustainable drop-in transport fuels from hydrothermal liquefaction of low value urban feedstocks


To prove the HTL technology pathway as a viable, sustainable and efficient  route for production of liquid drop in fuels for road transport.

Use of advanced HTL technology , and low H2 upgrading techniques for the valorization of low value aggregated urban sewage wastes and biowastes into drop-in quality synthetic gasoline and diesel.


To lead the research line related to the improvement sewage sludge as feedstock for HTL process and biofuel combustion properties through organic N and S removal:

  • pretreatment of feedstock using a mild & low temperature enzymatic hydrolysis.
  • extraction & purification  for protein-derived amino acid and peptides valorization.

Sustainability Assessment.
