20.500.12556/DKUM-91802 Valorization of biomass through anaerobic digestion and hydrothermal carbonization integrated process flowsheet and supply chain network optimization Utilization of biomass through anaerobic digestion and hydrothermal carbonization is crucial to maximize resource efficiency. At the same time, supply chain integration ensures sustainable feedstock management and minimizes environmental and logistical impacts, enabling a holistic approach to a circular bioeconomy. This study presents an integrated approach to simultaneously optimize the biomass supply chain network and process flowsheet, which includes anaerobic digestion, cogeneration, and hydrothermal carbonization. A three-layer supply chain network superstructure was hence developed to integrate the optimization of process variables with supply chain features such as transportation modes, feedstock supply, plant location, and demand location. A mixed-integer nonlinear programming model aimed at maximizing the economic performance of the system was formulated and applied to a case study of selected regions in Slovenia. The results show a great potential for the utilization of organic biomass with an annual after tax profit of 23.13 million USD per year, with the production of 245.70 GWh/yr of electricity, 298.83 GWh/yr of heat, and 185.08 kt/yr of hydrochar. The optimal configuration of the supply chain network, including the selection of supply zones, plant locations and demand locations, transportation links, and mode of transportation is presented, along with the optimal process variables within the plant. anaerobic digestion hydrothermal carbonization supply chain optimization process flowsheet optimization mathematical programming anaerobna digestija hidrotermalna karbonizacija optimizacijske verige matematično programiranje true true false MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/1996-1073/18/2/334 © 2025 by the authors Članek v reviji 2025-02-07 11:37:25 2025-02-07 11:37:25 2025-02-08 03:12:16 0000-00-00 00:00:00 2025 0 0 24 str. issue 2, [article no.] 334 Vol. 18 Jan. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-01-02 2025-01-10 2025-01-14 66 223256323 10.3390/en18020334 1996-1073 energies-18-00334.pdf energies-18-00334.pdf 1 D6771A0F35DC4E93FE7BBE4275187AF3 2f2aa65d2ebcabc1d00ccfc1b968a72367a4265e0a6996b66cefd927c0cf9caa b0fd4298-e53f-11ef-a41d-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188503 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
