“…Digestion continued until a clear solution obtained. The solutions were cooled down to room temperature and then transferred to a volumetric ask and made up to 100 ml (Fujimori et al 2012;Maris et al 2015;Vazquez et al 2017). The acidi ed water samples were ltered (0.45, Sartorius, Germany) before elemental analysis was carried out.…”

Inappropriate e-waste processing in the informal sector is a serious issue in developing countries. Field investigations in microscale informal recycling sites have been performed to study the impact of hazardous metal(loid)s (released from e-waste dismantling) on the environment (water and soil). Eight hazardous metal(loid)s (Pb, Cd, Cu, Zn, As, Hg, Ni and Cr) were found at elevated levels in the monitored water and soil samples (Sangrampur, West Bengal) as a consequence of widespread informal e-waste handling and primitive processing. Pd, Cu and As were found in high concentrations in water samples (1.62, 1.40, 0.03 mgL-1 respectively). Significant levels of Cu, Pd and Cd were detected in collected soil samples, both topsoil (Cu up to 2328.60 ± 217.60, Pb up to 342.90 ± 32.36 and Cd 18.34 ± 3.81 mgkg-1) and subsurface soil (2491.40 ± 276.20, 1853.33 ± 144.79, 25.90 ± 9.53 mgkg-1), compared to the levels of Zn, As, Hg, Ni and Cr. The results of seasonal variation indicated that higher levels of these hazardous meta(loids) were detected in the pre-monsoon (Nov – May) season than the rest of the year, as open dumping/burning of e-waste were practiced commonly and frequently in the monitored sites. The results highlighted that the composition and the handling of e-waste were important factors affecting the metal(loid) concentrations. E-waste policy and legislation have great influence on the handling and disposal procedures. A novel improved e-waste management practice has been proposed to encourage eco-friendly and safe e-waste disposal. It is recommended that regulatory agencies and manufacturers should create a road map to convince the informal sector to develop a systematic approach towards a more standardized formal e-waste management practices at the microscale field level.

“…Plastic is an important component of e-waste and comprises mainly thermoplastics that can be recycled by reprocessing [60][61][62][63]. More than 15 different types of engineering plastics have been documented in the manufacturing of EEE, including acrylonitrile-butadiene-styrene (ABS), high-impact polystyrene (HIPS), polypropylene (PP), polystyrene (PS), styrene-acrylonitrile (SAN), polyesters, polyurethane (PU), polyamide (PA), blends of polycarbonate (PC)/ABS, and blends of HIPS/poly(1,4-phenylene oxide) (PPO) [64].…”

The waste stream of obsolete electronic equipment grows exponentially, creating a worldwide pollution and resource problem. Electrical and electronic waste (e-waste) comprises a heterogeneous mix of glass, plastics (including flame retardants and other additives), metals (including rare Earth elements), and metalloids. The e-waste issue is complex and multi-faceted. In examining the different aspects of e-waste, informal recycling in developing countries has been identified as a primary concern, due to widespread illegal shipments; weak environmental, as well as health and safety, regulations; lack of technology; and inadequate waste treatment structure. For example, Nigeria, Ghana, India, Pakistan, and China have all been identified as hotspots for the disposal of e-waste. This article presents a critical examination on the chemical nature of e-waste and the resulting environmental impacts on, for example, microbial biodiversity, flora, and fauna in e-waste recycling sites around the world. It highlights the different types of risk assessment approaches required when evaluating the ecological impact of e-waste. Additionally, it presents examples of chemistry playing a role in potential solutions. The information presented here will be informative to relevant stakeholders seeking to devise integrated management strategies to tackle this global environmental concern.

“…7 Within the types of polystyrene (PS), high impact polystyrene (HIPS) corresponds to 30-40% of the worldwide PS production, finding applications in packaging, containers, appliance parts, household items and electronic equipment. [8][9][10][11][12] Actually, the waste produced by electronic equipment, known as "waste electrical and electronic equipment" (WEEE), reached 59 million tons by 2022, with HIPS representing 42% of all WEEE. 13,14 Current valorization techniques for polyolefins (including PS) involve pyrolysis reactions, perhaps the most common approach, 15 metathesis reactions, like ethenolysis, 16 hydrogenolysis over metal catalysts, 17 hydrocracking over bifunctional catalysts, 18 among others.…”
