Item type:Publication, 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.1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, 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.
