This paper presents a study that aimed to determine the mechanism of a process for Cr(VI) removal from aqueous solutions, using compost of carnation crop residues as the adsorbent. We assessed whether the microbiota present in the absorbent material affected the removal of Cr(VI) using respirometric measurements and evaluating the removal capacity using sterilized and not sterilized compost. Additionally, the compost was analysed before and after carrying out the Cr(VI) removal process, by quantification of the acidic functional groups and kinetic monitoring of pH, conductivity and redox potential difference. The results showed that, under the conditions used, the microorganisms present in the compost did not affect the process of Cr(VI) removal and that the mechanism can be described by an adsorption model coupled to the reduction, were this adsorption is mainly done on the acidic funct...

Fruit processing generates large amounts of by-products (BPs) that play a key role in the economic, social and environmental crisis. Although these residues are not usually used, they have better nutritional and bioactive value than the edible part. Considering that the circular economy is a sustainable approach to promote a zero waste processing system, the objective of this study was to use bibliometric analysis and data mining to provide a body of knowledge on trends in the field of research on fruit BPs under circular economy strategies. The publication of the SDGs has stimulated the adoption of circular economy strategies to use fruit BPs, which was reflected in the growth of scientific production since 2015. Although it is suggested that the field of study is at an exponential stage, development is limited by the lack of regulatory instruments to regulate the use of fruit BPs. The ...

El estudio propuesto desarrolla un modelo utilizando la dinámica de sistemas (Bertalanffy, 1998) para simular el impacto de un programa de gestión de residuos sólidos en los hogares del municipio de Tambo de Mora, provincia de Chincha, Region Ica. El análisis se realizó en base a las características actuales y a los modelos propuestos desarrollados para la gestión y las alternativas de reciclaje y compostaje en las plantas de tratamiento de aguas residuales antes de su eliminación en los vertederos sanitarios. El modelo se ha creado con el programa informático Stella® a partir de los datos de las encuestas históricas y estadísticas anteriores, así como de las encuestas de población para determinar los niveles de generación de residuos y realizar pruebas para identificar los residuos sólidos. Estos modelos incluyen diferentes componentes como: población, recogida de resid...
