Biochar is obtained from the thermochemical conversion of biomass in an oxygen-limited environment. Beyond its use for soil amendment and carbon sequestration, other value-added applications, such as a green environmental sorbent for different types of pollutants, are also of increasing interest. This paper reviews the available literature on the use of various feedstocks for biochar production as an initial step to compile the required inventory data from material flow data analysis. The environmental evaluation of different schemes of biochar production in a life cycle perspective reports the environmental impacts of the different alternatives, with more sustainable profiles than the use of activated carbon as conventional adsorption material. Moreover, most systems were validated as negative carbon processes with favorable performance regarding climate change mitigation. In particular, materials based on lignocellulosic waste were responsible for the highest environmental benefits, mainly due to their largest energy potential in comparison with other feedstocks.
