E-Waste Plastics in the Environment: Assessment, Characterisation, and Bioprocessing

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(4), P. 2122 - 2122

Published: Feb. 17, 2025

The accelerated growth of the electrical and electronic equipment market is a major driver behind increasing e-waste volumes worldwide. Although contains valuable resources, most remain unrecycled or improperly managed. Recycling efforts primarily focus on recovering metals, while plastic constituents overlooked. Furthermore, current recycling approaches have led to environmental contamination by hazardous materials. Recent for valorisation plastics demonstrated potential applications these materials their role in towards implementing more sustainable economy. While impact strategies been recently reviewed, thorough discussion that accounts impact, characterisation strategies, biotechnological treatment options remains lacking. Accordingly, this review addresses gap, discussing recent developments field. It focuses impacts, collection samples characterisation, as well innovative through strategies. Specifically, centred studies directly use derived from e-waste. progress has made contaminants remediation/bioprocessing type waste, challenges remain, including financial barriers, limited research volume compared related fields (e.g., metals), relevance concerns. This identifies need increased research, interdisciplinary collaboration, policy support overcome barriers advance management.

Recyclability of Plastics from Waste Mobile Phones According to European Union Regulations REACH and RoHS

Materials, Journal Year: 2025, Volume and Issue: 18(9), P. 1979 - 1979

Published: April 27, 2025

Small waste from electrical and electronic equipment (WEEE) such as mobile phones are rich in plastic components. Recycling is particularly challenging, since the main interest for recyclers printed circuit boards, valuable metals, while components usually destined thermal recovery. This study dedicated to assessment of recyclability potential fractions end-of-life (EoL) according European Union's (EU) Restriction Hazardous Substances (RoHS) Registration, Evaluation, Authorization Chemicals (REACH) directives. A total 275 items (inventoried casings, frames, screens) were dismantled 100 EoL analyzed identify type abundance polymers via Fourier-transform infrared spectroscopy (FTIR) presence hazardous elements Br, Cl, Pb, Cd X-ray fluorescence (XRF). Polycarbonate (PC) (57% samples) polymethyl methacrylate (PMMA) (27% items) identified most common prevalent polymers. In total, 67% contained Cl (0.84-40,700 mg/kg), 26% Br (0.08-2020 mg/kg). Hg was detected only one item (17 Cr found 17% items, with concentrations between 0.37 mg/kg 915 mg/kg, Pb 15% low (1-90 conclusion, present (with higher values smartphones), their below regulatory limits, suggesting compliance recycling regulations EU.

Analytical Methods for In-Depth Assessment of Recycled Plastics: A Review

Environments, Journal Year: 2025, Volume and Issue: 12(5), P. 154 - 154

Published: May 7, 2025

Assessing the detailed characteristics of recycled plastics is essential for evaluating their quality and suitability high-value applications compared to virgin polymers. This review provides a comprehensive overview advanced analytical techniques used characterizing chemical, structural, morphological, physical properties polymeric materials. The examined include Fourier Transform Infrared Spectroscopy (FTIR), Micro-Raman spectroscopy, X-ray Fluorescence (XRF), Inductively Coupled Plasma (ICP) techniques, Powder Diffraction (XRPD), Differential Scanning Calorimetry (DSC), Electron Microscopy (SEM). These methods are critically assessed effectiveness in detecting polymer degradation, surface structural alterations, presence contaminants—factors frequently introduced during mechanical recycling processes. For each technique, this outlines working principles, sample preparation protocols, illustrative case studies while discussing advantages, limitations, operational challenges. By synthesizing current knowledge methodological advancements, aims support development robust standardized assessment protocols. Enhancing reliability precision plastic characterization will improve acceptance as high-quality secondary raw materials, thereby facilitating upcycling contributing broader goals circular economy.
