Introduction: Electronic waste (e-waste) has emerged as a global concern due to the exponential growth in electronic consumption and inadequate disposal practices, specifically in developing countries. Among the various dimensions of this problem, the contamination of soil with e-waste has garnered significant attention, owing to its profound implications for environmental integrity and human health. Discussion: The soil contamination leads to diverse ecological repercussions, encompassing disruptions in the cycling of nutrients and biodiversity, as well as the potential for contaminants to accumulate in the food chain. Effective management strategies are imperative to address this multifaceted challenge, the implementation of governmental regulations, the adoption of sustainable e-waste recycling practices, and the raising of public awareness campaigns. The circular economy holds great potential for addressing the environmental and economic challenges. To build a more resilient and eco-friendly urban future, collaborative solutions are necessary to address infrastructural, policy, and awareness issues. In many circumstances, waste management is not primarily the government's duty. Non-governmental organizations (NGOs) and the business sector actively participate in trash management efforts through public education events and charity initiatives. This significant revolution has the potential to meaningfully advance smart city development through the use of technology-driven initiatives. Conclusion: By proactively addressing and reducing e-waste contamination in soil, we can mitigate the effects of environmental hazards and safeguard human health from the negative consequences associated with this burgeoning predicament.

Cadmium-contaminated soil significantly threatens global food security and human health. This scenario gives rise to significant worries regarding widespread environmental pollution. Biochar and arbuscular mycorrhizal fungi (AMF) can effectively immobilize cadmium in the soil in an environmentally friendly way. Existing studies have separately focused on the feasibility of each in remediating polluted soil. However, their association during the remediation of cadmium-polluted soils remains unclear. This review paper aims to elucidate the potential of biochar, in conjunction with AMF, as a strategy to remediate soil contaminated with cadmium. This paper comprehensively analyzes the current understanding of the processes in cadmium immobilization in the soil environment by examining the synergistic interactions between biochar and AMF. Key factors influencing the efficacy of this approach, such as biochar properties, AMF species, and soil conditions, are discussed. The influences of biochar–AMF interactions on plant growth, nutrient uptake, and overall ecosystem health in cadmium-contaminated environments are highlighted. This review indicates that combining biochar and AMF can improve cadmium immobilization. The presence of AMF in the soil can create numerous binding sites on biochar for cadmium ions, effectively immobilizing them in the soil. Insights from this review contribute to a deeper understanding of sustainable and eco-friendly approaches to remediate cadmium-contaminated soils, offering potential applications in agriculture and environmental management.
