Investigating the Socio-Spatial Dynamics of WEEE Collection in São Paulo, Brazil: A Data Mining Approach

Recycling, Journal Year: 2025, Volume and Issue: 10(2), P. 77 - 77

Published: April 16, 2025

The proliferation of electronic goods manufacturing and the subsequent rise in waste (e-waste) generation necessitate establishment efficient Waste Electrical Electronic Equipment (WEEE) reverse logistics systems, fostering collaborative efforts among manufacturers, retailers, government agencies. Given its importance, this theme has received considerable attention recent literature. This study focused on investigating relationships between socio-spatial characteristics distribution WEEE collection points city São Paulo, Brazil. To end, data mining (DM) techniques were applied to generate rules representing knowledge that explains relationship considered variables. results achieved (accuracy 81.25% Kappa statistic 74.71%), indicating consistent patterns, demonstrate potential proposed approach aid chain management. From a practical point view, produced is an important support for decision-making installation new points, considering target locations. In addition, research contributes responsible management solid recommended by Brazilian National Solid Policy (NSWP), as well advancement United Nations’ Sustainable Development Goals (UN SDGs), particularly SDG 11 (Sustainable Cities Communities) 12 (Responsible Consumption Production), sustainable practices resource utilization within urban contexts.

Feasibility Study of Closed-Loop Recycling for Plastic Generated from Waste Electrical and Electronic Equipment (WEEE) in South Korea

Energies, Journal Year: 2023, Volume and Issue: 16(17), P. 6358 - 6358

Published: Sept. 1, 2023

Plastics follow a linear economic structure, leading to detrimental environmental effects, such as global warming and ecosystem destruction, through incineration accumulation throughout their life cycle. This study examined the types, potential generation amounts, properties of recycled plastics from waste electrical electronic equipment (WEEE) assess feasibility closed-loop recycling WEEE under South Korea’s EPR system. Actual data companies were used determine factors, processing volume WEEE. As 2021, acrylonitrile-butadiene-styrene (53,363 tons), polypropylene (14,320 polystyrene (8199 tons) produced by both large small The meet specifications new products. In addition, an analysis using Life Cycle Assessment (LCA) methodology showed that effect (avoided emissions) reached 262,033 tons CO2 eq. per year. Therefore, is most suitable effective method for reducing greenhouse gases. paper presents amount generated within regulatory framework, providing valuable foundational policy development promoting use plastics.

Technology for Obtaining Sintered Components with Tailored Electromagnetic Features by Selective Recycling of Printed Circuit Boards

Crystals, Journal Year: 2024, Volume and Issue: 14(9), P. 820 - 820

Published: Sept. 20, 2024

The paper presents a technological approach for obtaining sintered components with tailored electromagnetic features from electromagnetically active powders through the selective recycling of electronic waste, in particular scrap components. Printed circuit board (PCB) scraps were submitted to succession grinding processes, followed by progressive magnetic and electrostatic separation, resulting two final fractions: metallic particles non-metallic including different oxides. Three types analyzed, i.e., powder after fine grinding, separation which further processed within spark plasma sintering furnace order obtain solid disk samples. All samples contained several classes oxides, also residual metals, leading specific thermal decomposition processes at temperatures, depending on nature oxides present studied materials. chemical analysis powders, via spectrometry X-ray fluorescence—XRF, emphasized presence mixture metal traces metals (mainly Ag), concentrations diminishing along purification process. most important was related dielectric parameters, it concluded that obtained proposed technology could efficiently substitute scarce raw materials actually used as additives composites, coatings paints, mainly due their high permittivity (above 6 all frequency domains) and, respectively, loss factor 0.2 cases, domains). We estimate described this is sustainable one according concept circular economy, reduce, minimum 15%, embodied GHG emissions generated information communications (ICT) devices advanced recycling.

Waste electrical and electronic equipment flows in Ukraine

Proceedings of the Institution of Civil Engineers - Waste and Resource Management, Journal Year: 2023, Volume and Issue: unknown, P. 1 - 8

Published: Nov. 21, 2023

This paper estimates the weight of electrical and electronic equipment on Ukrainian market (more than 800 thousand t/year). According to official statistics, waste (WEEE) in Ukraine is ∼20 t/year. study has showed a significant discrepancy between expected WEEE statistics. More 95% not taken into account flows. Taking lifespan various placed previous years, generation estimated at more 1 Mt/year. The share household 200 t/year (5 kg/year per inhabitant), which slightly lower that other eastern European countries. Computers electronics hold almost half WEEE. collection rate varies from 0.6% (household devices) 10.4% (batteries), depending category. much EU. Based findings this paper, one can conclude lack accounting commercial sectors creates underestimation flows data.

Geri Dönüşümün Alt Boyutlarının Sosyoekonomik Belirleyicileri: AB Ülkeleri Üzerine Ampirik Kanıtlar

Anadolu University Journal of Faculty of Economics, Journal Year: 2023, Volume and Issue: unknown

Published: Dec. 18, 2023

Sanayi Devrimi’nden bu yana, doğrusal ekonomik sistemlerin yol açtığı atık ve kaynak tükenmesi sorunları, döngüsel ekonomi kavramını ortaya çıkardı. Döngüsel ekonomi, azaltım, yeniden kullanma geri dönüşüm prensiplerini içermektedir. Böylece doğal kaynakların verimli kullanılması çevresel etkilerin en aza indirilmesi sağlanır. Geri dönüşümün belirleyicilerine yönelik literatürde pek çok çalışma yapılmıştır. Bu çalışmalar makro mikro ölçeklidir. Makro ölçekli çalışmalarda ambalaj atıklarının dönüşümünün belirleyicileri olarak sıklıkla sosyoekonomik faktörler kullanılmaktadır. Fakat her türünü aynı anda inceleyen bulunmamaktadır. çalışmada 6 farklı atığının incelenmiştir. Kullanılan modelde 28 AB ülkesinin 2015-2019 yılları arasındaki verileri panel veri analiz yöntemi ile İstatistiki açıdan anlamlı çıkan modellerden kağıt cam oranlarının bağımlı değişken olduğu modellerde Ar&Ge faaliyetlerinin ilgili materyallerin oranını arttırdığı sonucuna ulaşılmıştır. Cam dönüşümünde eğitimin olumlu etkisi de çalışmanın sonuçları içerisinde yer almaktadır. Çalışmada ayrıca beklentilerin aksine GSYH’nın plastik malzemenin dönüşümünü azalttığı
