“…Scalarized scores become discrete one-dimension magnitudes ranging from the selected best-to-worst targets, in which assumptions of relationships or accumulation between different indicators are not counted. 7 Many researchers have used these indicators under the sustainable design approach, considering techno-economic, 180 environmental, 181 and safety analysis. 173 Table 2 reports some of the most common indicators or indexes to assess chemical plants and designs.…”

These days, developing sustainable chemical facilities to generate biofuels, energy, bioproducts, and value-added chemicals has attracted attention. The above involves changing the traditional conception of transformation processes into more sustainable production based on the green chemistry principles, renewable energies, and the triple dimensions of sustainable development. Consequently, the addition of sustainability issues in process synthesis, analysis, and optimization of bioprocesses has become increasingly noteworthy. This study reports a literature review concerning the sustainable chemical process design framework based on process synthesis, analysis, and optimization methodologies. Studies on biorefinery/process synthesis approaches are analyzed and compared, offering a detailed overview of selected literature. These included hierarchical, mathematical, and mixed approaches. This review also outlined indexes and indicators for measuring sustainability in process design considering exergetic/energetic, environmental, economic, and safety aspects. It is worth mentioning the role that exergetic metrics are expected to play in measuring global process sustainability. Finally, the current research gap of process integration is analyzed, considering pinch analysis techniques, simultaneous heat and mass integration, and hybrid intensification−integration approaches.

“…En el caso 4 se tienen en cuenta la energía y las corrientes de productos del proceso. El algoritmo WAR introduce el concepto de equilibrio Impacto ambiental potencial (PEI), que implica el impacto ambiental de un flujo a través de los límites del sistema, debido a la masa o energía que cruza estos límites (8). Este índice se considera desde dos puntos de vista, la salida de PEI y la PEI generada, mostrados a continuación:…”

El desarrollo de procesos y actividades industriales que promueven el crecimiento sostenible de la cadena de producción apícola se ha vuelto muy importante en los últimos años. Hidromiel o mead es el nombre dado a un tipo de vino que se produce a partir de la fermentación alcohólica de la miel de abejas diluida; es una de las bebidas más antiguas y apetecida en el norte de Europa. En Colombia, la producción de hidromiel se da a pequeña escala. En este trabajo se evaluaron los impactos ambientales asociados a una planta existente de hidromiel ubicada en el Municipio de San Mateo Boyacá. Adicionalmente, se valoraron los posibles impactos que se generarían en el momento de implementar una planta de producción en el Departamento de Bolívar. El análisis se realizó usando la herramienta de diagnóstico WARGUI, un software de código abierto que permite evaluar tanto los impactos producidos como los consumidos por el proceso, en 8 categorías diferentes. Esta herramienta permitió realizar un estudio y presentar alternativas relacionadas con el uso de combustibles y residuos, información que contribuye a mejorar la sostenibilidad del proceso. Los resultados que se destacan son que no se presentó una diferencia considerable entre los impactos ocasionados al ambiente de la planta piloto de Boyacá y la simulada del Departamento de Bolívar y, que en general, ambas plantas presentaron un comportamiento sostenible desde el punto de vista ambiental.

“…Process simulation mainly implies selecting chemical components used in the process, choosing an appropriate thermodynamic model, setting processing capacity, using suitable operating units and setting up input conditions such as mass flow rates, temperature, pressure, among others [17]. For the simulation of large-scale production processes of chitosan microbeads was used the industrial process software Aspen Plus, the chemical species required for the simulations were taken from the software database.…”

Novel technologies for bio-adsorbent production are being evaluated on the lab-scale in order to find the most adequate processing alternative under technical parameters. However, the poor energy efficiency of promising technologies can be a drawback for large-scale production of these bio-adsorbents. In this work, exergy analysis was used as a computer-aided tool to evaluate from the energy point of view, the behavior of three bio-adsorbent production topologies at large scale for obtaining chitosan microbeads modified with magnetic and photocatalytic nanoparticles. The routes were modeled using an industrial process simulation software, based on experimental results and information reported in literature. Mass, energy and exergy balances were performed for each alternative, physical and chemical exergies of streams and chemical species were calculated according to the thermodynamic properties of biomass components and operating conditions of stages. Exergy efficiencies, total process irreversibilities, energy consumption, and exergy destruction were calculated for all routes. Route 2 presents the highest process irreversibilities and route 3 has the highest exergy of utilities. Exergy efficiencies were similar for all simulated cases, which did not allow to choose the best alternative under energy viewpoint. Exergy sinks for each topology were detected. As values of exergy efficiency were under 3%, it was shown that there are process improvement opportunities in product drying stages and washing water recovery for the three routes.
