“…When using a supply chain model that includes not only the characteristics of potential localizations but also other industrial sites that compete for the same feedstock, it is possible to capture the changes in costs for transportation in the entire studied system [22,43,44]. Generally, such models rely on plant-level evaluations to determine the biomass-to-product yield and the investment costs (or investment cost function), which are used as exogenous input data.…”

“…It addresses techno-economic aspects as well as endogenously determined feedstock prices, and thus the competition for feedstock. The proposed framework is illustrated empirically through a case study which builds on the observation that integration of biorefinery concepts with different host industries can offer benefits regarding overall efficiency and economic performance [3,[20][21][22]. In this context, existing forest industries are of particular interest due to the potential availability of biomass-derived by-products that can be used as feedstock, as well as significant experience in operating large-scale biomass supply chains.…”

Biofuels and biochemicals play significant roles in the transition towards a fossil-free society. However, large-scale biorefineries are not yet cost-competitive with their fossil-fuel counterparts, and it is important to identify biorefinery concepts with high economic performance. For evaluating early-stage biorefinery concepts, one needs to consider not only the technical performance and process costs but also the economic performance of the full supply chain and the impacts on feedstock and product markets. This article presents and demonstrates a conceptual interdisciplinary framework that can constitute the basis for evaluations of the full supply-chain performance of biorefinery concepts. This framework considers the competition for biomass across sectors, assumes exogenous end-use product demand, and incorporates various geographical and technical constraints. The framework is demonstrated empirically through a case study of a sawmill-integrated biorefinery producing liquefied biomethane from forestry and forest industry residues. The case study results illustrate that acknowledging biomass market effects in the supply chain evaluation implies changes in both biomass prices and the allocation of biomass across sectors. The proposed framework should facilitate the identification of biorefinery concepts with a high economic performance which are robust to feedstock price changes caused by the increase in biomass demand.

“…In this sense, considering the centrality of the manufacturing node for the provision of value-added intermediates or end-products, three circular supply network archetypes are proposed: (i) centralised; (ii) semi-centralised; and (iii) decentralised. The alternative network configurations can then be evaluated in terms of (Zetterholm et al, 2018): network objective; operational constraints imposed by the physico-chemical properties of the solid waste; technology and processing constraints; transportation and Supply network configuration archetypes for the circular exploitation of solid waste scheduling requirements; expected trade-offs, i.e. processing efficiency, economy of scale effects and financial viability; environmental sustainability impact.…”

This research aims to use network configuration theory to propose circular supply chain archetypes for the valorisation of solid waste. The proposed network configuration archetypes are differentiated by their levels of geographic dispersion, each representing coherent clusters of waste material and supply network characteristics for the valorisation of waste streams, namely: centralised, semi-centralised and decentralised. The different types of solid waste require local (e.g. wood, organic waste), regional (e.g. glass, plastics and rubber, paper and cardboard) or pan-regional (e.g. metals and alloys) network configuration options primarily dictated by the intrinsic physico-chemical properties of the wasted material and constraints related to the processing technologies. Furthermore, the proposed network configuration archetypes dictate operational considerations, such as procurement and preprocessing options for the wasted feedstocks, along with upscale production opportunities and distribution of the value-added intermediates or end-products.
