Proposal for used electronic products management in Mexicali
(Elsevier Inc., 2022-05-01)
Mexicali, a Mexican city located near the US-Mexico border, has faced several challenges related to adopting an integrated e-waste management system. Thus, the main objective of this work is to propose a new system to be implemented in phases. The current system is evaluated using several methodological approaches including field studies, surveys, interviews, and quantitative modeling via material flow analysis. We suggest the need to properly integrate both the formal and informal sectors to achieve the optimal system that mitigates environmental impacts while preserving the positive social and economic traits of the current system. Thus, without supplanting the current reuse, refurbishment, repair and maintenance practices, a hybrid system is proposed, based on a centralized facility that primarily handles those parts or materials that create environmental impacts and health hazards if mishandled. Furthermore, a decentralized transition phase toward the new system is recommended.

5R and hospital sustainability: Our contribution in the climate emergency. Part II. Rethink and research
(Sociedad de Anestesiologia de Chile, 2022-01-01)
Introduction: Climate change is a health problem and, at the same time, health systems are important contributors. Hospitals stand out due to their high rates of energy consumption, resources and waste generation. The purpose of the study is to know and identify the determinants of sanitary waste and the measures that can be implemented that allow reducing the production of hospital waste, seeking to achieve a general and updated appreciation of this phenomenon and taking into account hospital sustainability. Method: A bibliographic search was carried out in pubmed that included keywords related to the concepts of carbon footprint, recycling and hospital waste. The screening yielded a total of 37 articles and later 12 publications founded from references (or that were previously known by the authors) were added. Results: The results are presented into 5 points known as the “5 Rs”, named below. “Reduce” (through adequate segregation of waste, correct management of effluents and energy, significant reduction of excesses and automatic administration of anesthetic gases), “Reuse” (through device reprocessing, reusable material and donation), “Recycle”, “Rethink” (with examples such as selection of less polluting gases, selective use of containers, staff education) and “Investigate” through different models. Discussion: Several of the recognized measures could have an application in many hospital areas despite the fact that most of the available evidence refers to the operating room. The organization and education of the personnel is important in order to implement the measures found.

Study, qualitative-quantitative analysis, and sizing of the environmental impact of the photovoltaic panel recycling process
(EDP Sciences, 2024-01-01)
This study investigates the efficiency and environmental impact of photovoltaic panel recycling processes through qualitative and quantitative analyses, focusing on three case studies in Peru. The research addresses the pressing problem of solar panel waste management at the end of their useful life; this aspect is of particular importance due to the current boom in renewable energies. The first case study concerns a group of 5 rural houses in Puno consuming 10 kWh/day. The second case examines the rooftop PV system of the Institute of Mining Engineering of Peru, with a capacity of 20kW. The third case explores the Rubi solar power plant in Moquegua, with a capacity of 179.5 MW. The qualitative analysis details the sub-processes involved in solar panel recycling, while the quantitative analysis evaluates the energy payback time (EPBT) for each case. In addition, the study evaluates the environmental impact by measuring the total carbon footprint of the recycling processes. The results reveal the ratio in terms of carbon footprint of the panel recycling process to the total lifetime of the panel. This research provides a novel perspective on the use of photovoltaic panels as renewable energy and suggests future avenues for improving recycling technologies and policies.
