“…The major e-waste dumpsite in Pakistan is located in Karachi. According to Sohoo et al [87], Karachi is facing major environmental challenges due to overflowing drainage systems, rain canals blocked with trash, streets and roadsides impinged upon by e-waste dumps, and air pollution [88]. Karachi is located in the southern part of Pakistan and has a projected population of approximately 15 million people.…”

“…Based on the results of our systematic review, it is evident that the majority of the e-waste generated and imported in the selected countries is generally not handled in an ecologically safe manner. In all of the selected countries, e-waste is imported from developed nations, and it is disposed in an unregulated manner, with little or no regard for informal workers' safety and environmental protection [6,51,87,[192][193][194][195][196]. Consequently, communities living in these regions are frequently exposed to hazardous substances via direct exposure during the informal recycling processes or indirectly through environmental pollution.…”

Environmental and Health Consequences of E-Waste Dumping and Recycling Carried out by Selected Countries in Asia and Latin America

The volume of e-waste generated worldwide is surging, and it is set to escalate further due to continuing technological innovation and the early obsolescence of most electrical and electronic equipment (EEE). Even though there are many studies on e-waste management, the environmental and health consequences of e-waste regarding direct exposure during informal recycling and indirect exposure through environmental contamination are poorly studied. This study analyses the environmental and health consequences of e-waste dumping and informal recycling practices in selected countries such as Brazil, China, India, Mexico, and Pakistan. Several databases, such as Science Direct, ProQuest, Web of Science, and Emerald, were used to analyse studies from 2005 to 2022. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, 179 journal articles were evaluated. This study found that the majority of e-waste is poorly managed in terms of ecological safety and soundness. This study also found that illegal dumping, acid leaching, and open burning, which are practices that harm the environment and the well-being of e-waste workers, are still being performed by the selected countries. This study provides several practical suggestions for addressing the environmental and health consequences of e-waste dumping and recycling.

“…The belief that individual is responsible for protecting the environment, the significance of reducing waste, and using recycled materials is a more sustainable practice that reflects MN (Wan et al, 2021;Soomro et al, 2022). Individual values and priorities can significantly impact a person's willingness to reduce waste (Mintz et al, 2019;Sohoo et al, 2022). By conforming to these moral standards, people will be more inclined to waste sorting than dumping it irresponsibly.…”

IntroductionThe quick pace of technological advancement and urbanization has led to a significant increase in waste production, severely damaging environmental quality and human health. The sorting of waste is a viable option to reduce environmental hazards and attain high recovery rates in the cities. This research extended the theory of planned behavior (TPB) by integrating information publicity (IP) and moral norms (MNs).MethodsA conceptual model has been developed to explore the predictors of waste-sorting intention of households. The data from 361 Pakistani households have been collected using the purposive sampling method and analyzed via PLS-SEM.Results and discussionThe study's results revealed that IP is important in creating awareness and establishing moral norms regarding waste sorting among households. The findings further confirm that MN, attitude (ATD), subjective norms (SNs), and perceived behavioral control (PBC) sequentially mediate between IP and WSI. The findings of the current study provides useful practical implications to the practitioners and academicians to combat environmental pollution.

“…Takacs et al [ 12 ] conducted a systematic review to examine the effectiveness of life cycle-based interventions in improving the sustainability of production systems, concluding that integrated production systems should be preferred instead of conventional high inputs and outputs systems. The ecological cycle is oriented to the combination of planting and breeding, the cycle of agriculture and animal husbandry and green development, while simultaneously realizing comprehensive utilization of straws and transformation from manure to fertilizer [ 32 ]. Most importantly, the integrated production is the core of this pattern.…”

Over the past few decades, the supply of beef has increasingly become available with the great improvement of the quality of life, especially in developing countries. However, along with the demand for meat products of high quality and the transformation of dietary structure, the impact of massive agricultural greenhouse gas emissions on the environmental load cannot be ignored. Therefore, the objective of this study is to predict the annual greenhouse gas emissions of 10 million heads of beef cattle under both the ecological cycle model (EC model) and the non-ecological cycle model (non-EC model), respectively, in order to compare the differences between these two production models in each process, and thus explore which one is more sustainable and environmentally friendly. To this end, through the life cycle assessment (LCA), this paper performs relevant calculations according to the methodology of 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2019 IPCC Inventories). The results have shown that the total GHG emissions of the non-EC model were almost 4 times higher than those of the EC model, and feed-grain cultivation and manure management were main emission sources in both models. The non-EC model produced significantly more emissions than the EC model in each kind of GHG, especially the largest gap between these two was in CO2 emissions that accounted for 68.01% and 56.17% of the respective planting and breeding systems. This study demonstrates that the transformation of a beef cattle breeding model has a significant direct impact on cutting agricultural GHG emissions, and persuades other countries in the similar situation to vigorously advocate ecological cycling breeding model instead of the traditional ones so that promotes coordinated development between planting industry and beef cattle breeding industry.
