carried out using carbohydrase, protease and lipase [79]. The
enzymatic pre-treatment improved the yield of hydrochars and
bio-oil. Highest bio-oil yield was obtained at 350 °C [79]. The
results show that food waste can be potentially used for biooil
generation. In this regard, biooil holding NV, Tessenderlo, Belgium
is a leading company specializes in conversion of conversion of
waste to biooil by fast pyrolysis process [37].
