About This Conference The conference will be a forum for discussion of the advances in the pyrolysis and liquefaction of biomass, organic residues and wastes to intermediate products like bio-oil, biochar, bio-gas and torrefied materials. This will include slow, intermediate and fast pyrolysis, hydropyrolysis, solvent liquefaction and hydrothermal processing. Besides, a special session will be dedicated to pyrolysis of wastes from fossil origin, such as plastics.Final products are derived after proper fractionation, isolation, purification and/or upgrading, and contributions addressing the processing to marketable materials, chemicals and fuels are especially invited.
