“…Coffee cut stems (CCS) are the wooden residues resulting from the renovation of the coffee crop. This is an abundant waste, especially in a coffee‐producing country such as Colombia, where around 80 000–90 000 hectares are renovated per year, generating approximately 17 tonnes of dry wood per hectare . The traditional use of this residue is associated with the mechanical drying of the coffee grain but, given that this might not be the most appropriate and efficient usage of the raw material, other applications have been studied .…”

Moving from fossil‐based economies to bio‐based economies is one of humanity's most important necessities. Bio‐based economies are sustainable alternative ways to obtain chemicals, materials, and energy, and biorefineries have been proposed as promising technological schemes for this purpose. However, the economic performance of biorefineries is strongly related to the scale of the process, as different elements (energy consumption, equipment cost, etc.) vary to different degrees when the scale varies. This situation shows the importance of evaluating the performance of the biorefinery at different scales (analysis of scale) from the design stages. The problem with the analysis of these scales is that there is no unanimous definition of ‘scale’ and the term is used imprecisely to refer to the raw material or product. Taking this into consideration, this work proposed a strategy for determining the Minimum Processing Scale for Economic Feasibility (MPSEF) and identifying the minimum scale at which a given biorefinery can operate. As study cases, three different biorefineries, based on different raw materials (cocoyam, Andes berry, and coffee cut stems) were used to exemplify the applicability of the design strategy. The MPSEF calculated for Andes berry, coffee cut stems, and cocoyam‐based biorefineries were 9.27, 35.6 and 683 ton day−1, respectively. These results showed the application of the design strategy and how it allows the determination of the minimum amount of feedstock to be processed to achieve a positive economic performance, and from this point, to calculate the rate of return that an investor would require and the appropriate scale to achieve it. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The main energy requirement is usually related to the recovery of ethanol in the separation section. Current research is focusing on the development of new technologies that allow a reduction in the energy demand in some of the separation units of the process (Triana et al, 2011;Roth et al, 2013).…”

“…Usually, coffee residues are thrown into streams, a fact that causes contamination of water sources, which leads to the death of aquatic species (Funes et al, 2011). The residues and by-products of coffee can be used as fuel in different ways including: as a direct fuel, biogas, biodiesel, and bioethanol (fuel alcohol); in the case of bioethanol, studies such as Triana et al (2011), Navarro et al (2017, Muñoz & Daniel (2015), Navia et al (2011) and Gurram et al (2015) have demonstrated and studied the process under which stems, mucilage, and fresh pulp can be raw material for the production of fuel alcohol.…”

The present article exposes a model of Mixed Integer Linear Programming (MILP) as a support for strategic decision making, guided to the location of facilities in ethanol supply chains under a configuration of collection centers of raw material and production plants, directly impacting costs related to logistics and operations. The model is applied to the supply chain for the production of ethanol from two by-products and a coffee residue (pulp, mucilage, and stems, respectively) in Colombia. The results obtained by the model allow identifying locations for the corresponding links to the three types of biomass considered, and the flows of raw material between coffee producing departments and collection centers, from the latter to production plants, and from this, where the transformation of ethanol to mixing centers is generated.
