Implementación del reglamento sobre condiciones sanitarias para la reutilización de aguas grises: reúso residencial - análisis desde la experiencia comparada
(Universidad de Chile, 2021)
El 15 de febrero del año 2018 se publicó en el Diario Oficial la Ley Nº 21.075 del Ministerio
de Obras Públicas, que establece y regula los sistemas de reutilización de las aguas
grises, aplicable a áreas urbanas y rurales. Esta normativa impulsada...

Centro de educación participativa para el reciclaje de residuos orgánicos San Bernardo
(Universidad de ChilePrograma Cybertesis, 2007)
El problema que se plantea es el precario funcionamiento del reciclaje en nuestro país, debido a que su aplicación es prácticamente inexistente y ha sido subordinada a otros métodos de tratamiento de la basura. Se propone una mirada ambientalmente...

Reciclabilidad, normativa vigente de los polímeros polipropileno y poliestireno reciclados posconsumo y migración química de sus componentes, para su uso potencial en aplicaciones de envasado de alimentos
(Universidad de Chile, 2022)
polímero reciclado conforme al aumento del número de reprocesos en el reciclaje mecánico. Esto implica la disminución del peso molecular, lo cual altera propiedades mecánicas de los mismos, y conduce además a una mayor migración de componentes...
Food packaging are a fundamental element in the food industry, allowing food to be stored, protected, and contained without altering its physicochemical or organoleptic properties. To guarantee the safety of the containers to the consumer, the interactions of the system-container-environment must be considered with the main concern in the chemical migration of the components of these containers, thus ensuring that the material used is inert and does not alter the food. Along with this, it is important to consider the environmental impact that packaging has caused in recent decades, which is why waste management strategies have had to be developed to combat this problem. Due to the, this work aims to analyze the feasibility of the potential use of post-consumer mechanically recycled polypropylene (PP) and polystyrene (PS) polymers in the food packaging industry. To respond to what has been raised, the document consists of a bibliographic review, in which, to search for information, review and research articles were included between 2011 and 2022 along with fundamental legislative documents for the review. In addition, to have a more complete perspective of the subject, it was decided to incorporate a limited cross-sectional descriptive study, which was carried out based on a qualitative survey of companies in the food and plastics sector in Chile, to obtain information regarding the non-use of post-consumer recycled materials with a focus on polypropylene and polystyrene. These results were contrasted with a survey carried out by Polymer Comply Europe, applied in Europe to obtain information on the main barriers that prevent the use of recycled material. The results indicated that the recycled material would be of a lower quality compared to the virgin material due to the thermal degradation behavior that the recycled polymer presents according to the increase in the number of reprocesses in mechanical recycling. This implies a decrease in molecular weight, which alters their mechanical properties, and leads to a greater migration of potentially toxic components compared to virgin material, directly influencing the safety of the polymers. Along with this, surveys conducted in Chile and Europe indicate that the main barriers to the use of recycled materials, including post-consumer polypropylene and polystyrene, are supply instability, problems with the quality and safety of the material compared to virgin polymer, the little support received from customers, the insufficiencies present in the regulatory legal framework and the lack of research on the potential application of these post-consumer recycled materials in food packaging. These difficulties are confirmed by various authors, who describe these problems as the possible cause that, to date, the use of post-consumer recycled PP and PS polymers are not allowed to be used as materials in contact with food. Therefore, this work aims to be an approximation for researchers and the food packaging industry, providing information on various studies and investigations that have been carried out to date, thus showing the current reality of Chile and the world, with the purpose of generating a theoretical framework for future developments and processing technologies of post-consumer recycled PP and PS for its industrial application in packaging intended to be in contact with food...
