Abstract
Bio-based supply chains are by nature complex to optimize. The new logistic concept of integrated biomass logistical center (IBLC) provides us the opportunity to make full use of the idle capacity for a food/feed plant to produce biobased products so that the entire chain efficiency can be improved. Although research has been conducted to analyze the IBLC concept, is yet to be an optimization model that can optimally arrange the activities in the supply chain where an IBLC stands in the middle. To fill the knowledge gap in the literature, this paper makes the first step to develop a MILP model that enables biobased supply chain optimization with the IBLC concept, which supports logistic and processing decisions in the chain. The model is applied in a case study for a feed and fodder plant in Spain where managerial insights have been derived for transferring the plant to a profitable IBLC.
Highlights
The large world population leads to enormous energy consumption and per-capita energy use is rising [3]
To fill the aforementioned knowledge gap, this paper developed the first mixed-integer programming model that optimizes the machinery utilization using the integrated biomass logistical center (IBLC) concept where the processing of biomass is combined into the business of existing food and/or feed manufacturing plant
We developed a mixed integer linear programming (MILP) model to optimize biomass supply chains using IBLCs
Summary
The fast-growing world population requires more food to be supplied but the total amount of land for agricultural production hardly changes [2]. The large world population leads to enormous energy consumption and per-capita energy use is rising [3]. Fossil fuels are the major source of GHG emissions which is responsible for climate change [5]. The wide availability of biomass enables biofuel to become an appealing source of renewable energy to replace fossil energy [6]. The processing of biomass does not contribute to a build-up of CO2 in the atmosphere, because the amount of carbon taken up during plant growth is roughly the same as the emission of carbon during the conversion of biomass [7]
