The primary reasons for the frequent replacement of mobile phones include the release of new models with improved capabilities, marketing strategies by manufacturers encouraging consumers to upgrade, and the perceived obsolescence of older models. Many consumers are enticed by features such as better cameras, faster processors, and enhanced connectivity, prompting them to discard their still-functional devices.
This rapid turnover contributes to the growing e-waste problem, as millions of mobile phones are discarded each year. Recycling programs specifically targeting mobile phones are essential to manage this waste stream. These programs can recover valuable materials, such as precious metals and rare earth elements, reducing the need for new raw materials and mitigating the environmental impact of mining.
Low Circularity in E-Waste Management
The concept of a circular economy aims to reuse e-waste materials, reducing the need for new raw materials. However, the current circularity rate for e-waste is only 9%, indicating minimal improvement in reusing materials from waste back into production. The linear economy model of ‘take, make, dispose’ still dominates e-waste management, underscoring the need for better recycling practices.
In a circular economy, products are designed for durability, repairability, and recyclability. Materials from discarded products are recovered and reused in the production of new items, creating a closed-loop system that minimises waste. However, several barriers hinder the transition to a circular economy for e-waste, including the complexity of electronic devices, lack of standardisation in product design, and insufficient recycling infrastructure.
Efforts to improve circularity in e-waste management include promoting eco-design principles, developing advanced recycling technologies, and implementing extended producer responsibility (EPR) schemes.
