EntreNiebla: experimentation and development of composite material, based on wicker waste

Proyecto EntreNiebla: Development of a composite material with wicker residue, financed by the cnca and Fondart 2017, folio 413281; is a research project based on experimentation of composite materials created on the basis of organic waste, which aims to produce a material based on the willow fiber in disuse, using low complexity technology. To achieve this, a. an information survey carried out to quantify how much wicker residue the Chimbarongo artisans generated. This would allow determining the productive capacity of the material; and b. the process of composition and conformation of the composite material was evaluated, to establish a procedural method for its conformation and a technical sheet of its main characteristics. Based on this results, possible applications were explored around the creation of secondary packaging for products manufactured by the Cooperativa de Berries from Chimbarongo. In order to: give the waste an useful life, avoid its incineration, and reduce the environmental impact that generates in the community; while also creating added value in local products, from a package that reuses raw material that is being discarded

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Desarrollo de hormas cad/cam para el tejido con micro-huira de mimbre maduro blanco

Memoria para optar al título de Diseñador IndustrialEl presente documento corresponde al desarrollo de un proyecto de tipo diseño de producto, cuyo objetivo es ser parte del macro proyecto de rescate patrimonial de la artesanía de tejido de mimbre. “Mimbre: Diseño e innovación en saberes tradicionales”. El proyecto se enfoca en el desarrollo de hormas extraíbles para tejido de micro-huiras de mimbre maduro blanco, con el fin de hacer un puente de colaboración entre diseño y artesanía que genere una nueva manera de desarrollar productos; utilizando metodología de diseño y la incorporación de tecnologías de fabricación CADCAM para la confección de dichas hormas. Para esto, se realizó una revisión bibliográfica para recopilar antecedentes y establecer las definiciones que guían el estudio. Además, de realizar una visita a la comuna de Chimbarongo, como trabajo de campo, con el fin de conocer empíricamente cómo se trabaja el tejido de huira a través de hormas, lo que permitió establecer las bases del proyecto. Esto permitió establecer los lineamientos para desarrollar una propuesta de horma fabricada utilizando tecnología CAD-CAM para tejido semicerrado y cerrado

Para ello, a. se realizó un levantamiento de información en torno a la cuantificación del residuo de mimbre generado por los artesanos de Chimbarongo, para determinar la capacidad productiva del material; y b. se evaluó el proceso de composición y conformación del material compuesto, para establecer un método procedimental para su conformación y una ficha técnica de sus características principales. En base a ello, se investigan posibles aplicaciones, en torno a la creación de packaging secundario, para productos elaborados por la Cooperativa de Berries de Chimbarongo, con el fin de otorgar al residuo una vida útil, evitar su incineración y disminuir el impacto ambiental que genera en la comunidad; y a su vez, crear valor agregado en los productos locales, a partir de un empaque que reutilice la materia prima que está siendo desechada
