“…by increasing its turbulence (e.g. Agarski et al, 2017 ). Although limited to few overall case studies, this additional subdivision highlighted the major advantages of Fluid dynamic optimization compared to Structural optimization: Average impact (42% vs. 22%), GWP (44% vs. 21%), AP (32% vs. 16%), EP (33% vs. 12%), PMF (58% vs. 28%), RD (32% vs. 13%), WC (26% vs. 55%).…”

“…For instance, the paper of Agarski et al ( 2017 ) compares the environmental impacts of catalyst fluid (option 1) and ultrasonic aerosol (option 2) to perform a chemical synthesis process. This case study was associated with the “Design for reducing waste” strategy because option 2 allows to eliminate the catalyst fluid that is instead used and disposed in option 1.…”

The goal of pursuing the circular economy (CE) is spreading more and more in industry, also driven by the introduction of new regulations, considerably affecting product design. However, a quantitative and rigorous evaluation of the environmental impacts of the results obtained by different design strategies used to implementing CE is missing in the literature. Those available only evaluate certain aspects of the life cycle of few products, belonging to specific application fields, in a qualitative way or they refer only to the global warming potential. This study provides a quantitative assessment of the environmental impacts reductions arising from the application of some common design strategies for implementing different CE options (e.g. reuse, waste to energy, remanufacturing), by using some standard indicators. The results were obtained by manually analysing 156 selected case studies of comparative life cycle assessment (LCA), extracted from 136 scientific articles. In them, the environmental impacts of design solutions for CE are compared with those of other solutions were wastes are not exploited. The obtained results have been used to evaluate the different design strategies for CE and to hierarchize them based on environmental sustainability of the solutions associated with them. In addition, an economic evaluation of the strategies, based on the life cycle costing methodology and exploiting the data available in the same articles, was also provided. Among the main achievements, it was found that the hierarchy of the CE options, pursued by the design strategies, to improve environmental sustainability is different from that provided by other studies. In addition, the environmental benefits associated with the different CE options strictly depend by the applied design strategies and the considered products. Graphical abstract

“…Los procesos de síntesis de catalizadores dan lugar a la formación de residuos que comprenden principalmente gases de escape, residuos líquidos y una cantidad menor de residuos sólidos. El impacto medioambiental depende en gran medida del proceso de síntesis y de los materiales de partida (Agarski, et al, 2017). Es bastante complicado desglosar los datos para entender completamente los modelos de AVC y, sobre todo, utilizar sus resultados para mejorar los análisis o para gestionar otros nuevos (Bobba et al, 2016).…”

En los próximos años, el uso de catalizadores sigue aumentando, ya que desempeña un papel importante en la fabricación de productos básicos, petroquímicos, químicos, farmacéuticos y alimenticios, además de servir como una herramienta para la mejora el rendimiento de las nuevas tecnologías energéticas. Por otro lado, los procesos de síntesis de catalizadores generan residuos en los laboratorios y fábricas, convirtiéndose en un desafío ambiental debido a su composición particular. En este contexto, se pueden utilizar herramientas como el análisis de ciclo de vida (ACV) para cuantificar los impactos ambientales e identificar los puntos débiles, que deberán ser mitigados. Por lo tanto, en esta revisión, se evaluaron tres catalizadores: Zn, Pd, Pt, al igual que sus impactos ambientales. Finalmente, se encontraron algunos de los usos potenciales en la reducción de las emisiones de gases de efecto invernadero (GEI) y el aumento en el rendimiento de la producción de energía y urea, así como el aumento del rendimiento en el gas total y de hidrógeno; también se consideró el uso de los residuos de base como catalizadores, por ejemplo, en la industria del petróleo y las cenizas generadas durante los procesos de combustión de residuos sólidos urbanos (RSU), neumáticos y carbón

“…Despite obtaining high-performance catalysts, thermo-chemical synthesis routes are complex from a cost-effective point of view: they last from 30 to 50 hours or even up to a few days and require large amounts of complex chemical composition solutions [2,[4][5][6][7][8][9][10]. Hence, it is highly desirable to simplify the catalyst production processes by reducing the number of process stages and in conjunction also achieve a lower environmental impact when compared with the thermo-chemical synthesis routes [11][12][13].…”

This research aimed to develop a novel catalyst based on WO3/ZrSiO4 system for halogenated hydrocarbons processing. The production method of this catalyst involved extrusion and as such was simplified compared to thermo-chemical synthesis routes. It had a reduced number of process stages and a lower environmental impact at the same time. In order to examine the phase composition of the catalyst after sintering at 800 °C, the XRD analysis was carried out. The catalyst was then tested in chlorodifluoromethane dehalogenation process on laboratory scale at temperatures of 300, 400 and 500 °C in the presence of water vapor. Catalyst achieves high dehalogenation efficiencies of 88.6, 95.9, and 99.5 % for each of the process temperatures, respectively. Obtained results are in the range with those achieved by using thermo-chemically prepared dehalogenation catalysts.
