The main types of biomass for bioenergy include lignocellulosic woody biomass (e.g., pine, eucalyptus, willow), lignocellulosic crops (e.g., perennial grasses, agricultural residues, crops for oil, sugar or starch), and waste biomass such as wet manure or municipal solid waste (MSW). The use of primary biomass sources (i.e., dedicated crops) for bioenergy with carbon capture and storage (BECCS) raises concerns about sustainability due to the potential competition with other land uses and the need for fertilisation and irrigation . Secondary sources of biomass (e.g., waste and residues) are potentially more environmentally sustainable, and economical . The biomass supply chain consists of production, harvesting/collection, processing, and transport steps. Each biomass feedstock pathway will be distinct in terms of energy needs, carbon footprint, land requirements, and cost. Furthermore, each biomass feedstock type will differ in terms of chemical composition, and physical properties. Thus, it will be important to consider each case specifically when determining the sustainability, and suitability of different biomass feedstocks.
