20.1 Introduction
Debates about the feasibility of biofuels and sustainability started many years ago, chiefly centred on liquid first‐generation biofuels based on food crops. The development of new processing technologies able to transform lignocellulosic raw materials into heat, power, gases, or even advanced biofuels, transformed the debate in many ways, especially by enabling new approaches for determining the biomass footprint of dedicated plantations, forestry, or the collection of agricultural residues, in combined energy–food systems (Weiser et al. 2014). Industry and policy makers face complex discussions about sustainability criteria, from food and fuel conflict debates around land availability and food security issues, to impacts and benefits from carbon footprint, indirect land use change effects, emission savings or biodiversity and ecological issues. Can we grow biomass without harming the environment? Are lignocellulosic feedstock options viable to produce energy in the rural sector? Are ...
