Abstract
<jats:p>The design of multipurpose processes in rural agroindustry considers quality criteria, environmental sustainability, and economic feasibility. The problem arises from the limited integration between process simulation and environmental assessment in traditional production systems of granulated panela (GP) and sugarcane honey (SH) in Pastaza, Ecuador. The objective was to propose a methodology for the design of sustainable multipurpose processes through simulation and the application of the GREENSCOPE tool. The methodology combined mass and energy balances, quality attribute analysis under sigma level, economic evaluation using net present value (NPV), internal rate of return (IRR), and discounted payback period (DPP), along with environmental analysis through efficiency, energy, economic, and environmental indicators. Different production scenarios were simulated with percentage combinations of GP and SH in batches of 10, 120, and 1560 units. Results show that the alternative consisting of 60% GP and 40% SH in 120 batches achieved the highest profitability, with an NPV of 141,014.59 USD and an IRR of 45.80%, while meeting technical and quality criteria. The GREENSCOPE analysis identified environmental impacts mainly associated with emissions from biomass combustion. The multipurpose production of 60% granulated panela and 40% sugarcane honey in 120 batches was identified as the best technological and economic alternative for the analyzed rural agroindustry.</jats:p>
