“…by biobased products, and has significant impact on the sustainability of biorefineries. Sammons Jr et al [115] proposed a general systematic framework for optimizing the product portfolio and process configuration of biorefineries. They have discussed on the economic aspects of delivering biobased products and further encapsulated the optimization framework to enable the decision-making process primarily concerned with whether a certain product should be sold or further processed, or with which processing route to pursue if multiple production pathways exist for a special product.…”

Abstract:The aim of the current paper is to discuss the sustainability aspect of biorefinery systems with focus on: biomass supply chains, processing of biomass feedstocks in biorefinery platforms and sustainability assessment methodologies. From the stand point of sustainability, it is important to optimize the agricultural production system and minimize the related environmental impacts at the farming system level. These impacts are primarily related to agri-chemical inputs and the related undesired environmental emissions and to the repercussions from biomass production. At the same time, the biorefineries needs a year-round supply of biomass and about 40-60% of the total operating cost of a typical biorefinery is related to the feedstocks chosen, and thus highlights on the careful prioritization of feedstocks mainly based on their economic and environmental loadings. Regarding the processing in biorefinery platforms, chemical composition of biomasses is important. Biomasses with higher concentrations of cellulose and hemicelluloses compared to lignin are preferred for bioethanol production in the lignocellulosic biorefinery, since the biodegradability of cellulose is higher than lignin. A green biorefinery platform enables the extraction of protein from grasses, producing an important alternative to importing protein sources for food products and animal feed, while also allowing processing of residues to deliver bioethanol. Currently, there are several approaches to integrate biorefinery platforms, which are aimed to enhance their economic and environmental sustainability. Regarding sustainability assessment, the complexities related to the material flows in a biorefinery and the delivery of alternative biobased products means dealing with multiple indicators in the decision-making process to enable comparisons of alternatives. Life Cycle Assessment is regarded as one of the most relevant tools to assess the environmental hotspots in the biomass supply chains, at processing stages and also to support in the prioritization of any specific biobased products and the alternatives delivered from biorefineries.Keywords: biorefinery, biomass feedstock, sustainability, biobased product, environmental performances, economic performances, Life Cycle Assessment 2 IntroductionThe societal need of energy and materials is predicted to reach a crisis point in the near future [1]. This is because of the coupling between escalating demand and cost of fossil fuels upon which the production of chemicals, materials and energy conversions still depend. The high energy intensity in material production has sustainability impacts on the energy sector, environment and economy [2]. Currently fossil fuels contribute about 80% of the global energy demand, and even if the current political commitments and strategies to tackle the issues of climate change and energy insecurity, as envisioned by different countries are in place, the global energy demand in 2035 is still projected to rise by 40% with fossil fuels contributing 75% [3].

“…Among the various competing biofuel technologies, biochemical ethanol production from lignocellulosic biomass has received the most attention in the literature (Humbird et al, 2011;Kazi et al, 2010). Several studies have focused on the synthesis and technoeconomic evaluation of biorefineries based on the aforementioned platforms (Dale and Ong, 2014;Floudas et al, 2012;Martín and Grossmann, 2011;Pham and ElHalwagi, 2012;Sammons et al, 2008;Tao et al, 2011;Wright and Brown, 2007).…”

“…Studies have previously been made in which conjoint analysis results has been integrated in a Life Cycle Assessment (LCA) as weights in the environmental valuation phase [6]. There has been some attempts to integrate process integration with economic modeling [7] but to the best of out knowledge studies of social values has never been integrated in a process integration project. Further information on conjoint analysis can be found in [8][9][10][11].…”

Industrial energy systems are complicated networks where changes in one process influence its neighboring processes. The network complexity increases if production/use of bio fuel is introduced in an existing system. Process integration can be a useful tool to study such systems and thus avoid sub optimization.However, changes in an industrial complex do not only influence the technical values of energy and material efficiency. The social impact is also important and sometimes is comparable to that of technical factors. A process integration project has recently been carried out for a paper mill in northern Sweden with a side view on future expansion with a bio refinery. An activity to study the social impacts were included through a Conjoint analysis, a stated preference method that combines statistics and interviewing technique.The results indicate that the participants are divided in four groups, the largest group focusing on a change in the process towards a bio refinery, the second largest focusing on the local environment. The third and fourth group both look at the local forestry, one group wanting to increase local forest production, and one rejecting an increase.
