“…This reduction in yield may be attributed to the leaching of potassium ions from the catalyst during the recovery process . Additionally, pore blockage of the catalyst active sites by reactants and products, such as triglycerides and glycerol, may have also contributed to the inhibition of catalyst activity . The total basicity decreased significantly, indicating the loss of potassium compounds on the support.…”

A new sustainable solid carbon catalyst has been developed for biodiesel synthesis using pyrolytic coconut shell ash (CSA). The CSA support was loaded with various amounts of potassium carbonate (K2CO3), and response surface methodology with a central composite design was used to optimize the transesterification process. The best-performing catalyst was the 30 wt % K2CO3/CSA catalyst. The optimal conditions included a catalyst loading of 3.27 wt %, methanol:oil molar ratio of 9.98:1, reaction time of 74 min, and temperature of 65 °C, resulting in an obtained biodiesel yield of 97.14%. This catalyst was reusable for up to four cycles, but a reduction in the biodiesel yield was observed due to potassium ion leaching during the recovery process. A techno-economic analysis to assess the financial viability of the project revealed a net present value of 5.16 million USD for a project lifetime of 20 years, a payback period time of 2.49 years, and an internal rate of return of 44.2%. An environmental assessment to evaluate the impact of global warming potential from the production of biodiesel revealed a lower level of carbon dioxide emission (1401.86 ton/y) than in the conventional process (1784.6 ton/y).

Membrane technology has been embraced as a feasible and suitable substitute for conventional time- and energy-intensive biodiesel synthesis processes. It is ecofriendly, easier to run and regulate, and requires less energy than conventional approaches, with excellent stability. Therefore, the present study involved the synthesis and application of a highly reactive and recyclable Titania-based heterogeneous nanocatalyst (TiO2) for biodiesel production from nonedible Azadhiracta indica seed oil via a membrane reactor, since Azadhiracta indica is easily and widely accessible and has a rich oil content (39% w/w). The high free fatty acids content (6.52 mg/g KOH) of the nonedible oil was decreased to less than 1% via two-step esterification. Following the esterification, transesterification was performed using a heterogeneous TiO2 nanocatalyst under optimum conditions, such as a 9:1 methanol–oil molar ratio, 90 °C reaction temperature, 2 wt.% catalyst loading, and an agitation rate of 600 rpm, and the biodiesel yield was optimized through response surface methodology (RSM). Azadhiracta indica seed oil contains 68.98% unsaturated (61.01% oleic acid, 8.97% linoleic acid) and 31.02% saturated fatty acids (15.91% palmitic acid, 15.11% stearic acid). These fatty acids transformed into respective methyl esters, with a total yield up to 95% achieved. The biodiesel was analyzed via advanced characterization techniques like gas chromatography–mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FT-IR), and nuclear magnetic resonance (NMR), whereas the catalyst was characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), and Fourier transform infrared spectroscopy (FT-IR). Due to its physicochemical properties, Azadirachta indica seed oil is a highly recommended feedstock for biodiesel production. Moreover, it is concluded that the Titania-based heterogeneous nanocatalyst (TiO2) is effective for high-quality liquid fuel synthesis from nonedible Azadirachta indica seed oil in a membrane reactor, which could be an optional green route to cleaner production of bioenergy, eventually leading to sustenance, robustness, and resilience that will aid in developing a holistic framework for integrated waste management.

“…Al evitar el uso de agroquímicos y fomentar la biodiversidad, se promueve la salud humana y se protege la biodiversidad y los recursos naturales. Además, la producción de banano orgánico puede generar mayores ingresos para los productores debido a que los productos orgánicos suelen tener un mayor valor en el mercado internacional (Daimary et al, 2023). Pero a pesar de los beneficios de la producción de banano orgánico, todavía existen desafíos en la implementación de esta modalidad de producción en el Ecuador.…”

La producción de banano en el Ecuador es una actividad económica de gran importancia para el país, siendo uno de los principales productos de exportación. Sin embargo, la producción convencional de banano ha generado controversias debido al impacto ambiental que genera. En esta investigación, se analiza cómo las empresas bananeras pueden tener un impacto positivo en el medio ambiente a través de una gestión ambiental eficaz tanto en la producción convencional como orgánica de banano. Se presentan las principales prácticas sostenibles que pueden ser implementadas en la producción de banano convencional y orgánico, incluyendo la gestión integrada de plagas, el uso eficiente del agua y energía, la reforestación y conservación de áreas naturales, entre otros. También se discuten los desafíos que enfrentan las empresas bananeras en la implementación de prácticas sostenibles y cómo estos pueden ser superados. Palabras clave: Responsabilidad social, medio ambiente, empresas bananeras, sostenibilidad. ABSTRACT Banana production in Ecuador is an economic activity of great importance for the country, being one of the main export products. However, conventional banana production has generated controversy due to its environmental impact. This research analyzes how banana companies can have a positive impact on the environment through effective environmental management in both conventional and organic banana production. The main sustainable practices that can be implemented in conventional and organic banana production are presented, including integrated pest management, efficient use of water and energy, reforestation and conservation of natural areas, among others. It also discusses the challenges faced by banana companies in implementing sustainable practices and how these can be overcome. Keywords: Social responsibility, environment, banana companies, sustainability.
