Bio-oil also contains high value bio-chemicals of relevance to food and pharmaceutical
industries.
The biochar product of fast pyrolysis is granular and displays a lower calorific value (23–
32 MJ kg-1) than that of slow pyrolysis (Demirbas, 2001). However, there are currently no
published studies to assess the effects of biochar from fast pyrolysis when it is applied to
soil. It is highly likely that condensed volatiles will be present in the product and that this will
affect its performance and desirability.
