Rising E-waste Crisis Demands Immediate Focus on Raw Material Retrieval
By Faridat Salifu
As global reliance on technology surges, a shadow crisis is emerging: the rapid accumulation of electronic waste (e-waste). From smartphones and laptops to household appliances, the disposal of obsolete electronic devices is creating environmental and economic challenges that are becoming increasingly urgent.
A growing body of research indicates that efficient recovery of raw materials from e-waste may be the key to addressing this crisis, offering a pathway to environmental protection, resource efficiency, and economic growth.
E-waste is often viewed as trash, but hidden within discarded electronics lies a wealth of valuable materials. Items such as gold, silver, copper, and rare earth elements are embedded in the devices that power our modern world.
Mining these materials directly from the earth is an environmentally destructive process, contributing to habitat destruction, water pollution, and deforestation. But recovering these elements from discarded electronics offers an alternative – one that could reduce the need for mining and mitigate the environmental harm associated with it.
Experts suggest that just one ton of e-waste contains more gold than a ton of mined ore. Recovering such materials not only conserves finite natural resources but also reduces the escalating costs associated with sourcing these elements from dwindling reserves. For industries that rely heavily on these materials, improving e-waste recycling could be both a cost-saving and environmentally sustainable solution.
The financial potential of raw material recovery from e-waste is immense. The global recycling industry has long recognized that turning discarded electronics into usable raw materials can create jobs, reduce costs, and support new economic models.
This concept is the backbone of the circular economy – an approach that seeks to extend the lifecycle of products, reusing materials and minimizing waste.

By investing in proper recycling infrastructure and technology, countries can reap the economic benefits of the circular economy, while reducing their dependence on virgin materials.
Moreover, the toxic elements contained in e-waste – such as lead, mercury, and cadmium – pose serious environmental and health risks. When improperly disposed of, these substances can leach into soil and groundwater, endangering ecosystems and human health. Effective recycling systems ensure that hazardous materials are safely managed, thereby reducing the likelihood of environmental contamination.
Despite the obvious benefits of raw material recovery, e-waste recycling practices remain inefficient in many parts of the world. The Global E-Waste Monitor 2020 reported that the world generated 53.6 million metric tons of e-waste in 2019, and this figure is projected to grow as technology continues to evolve at a rapid pace.
However, less than 20% of e-waste is formally recycled, with much of it ending up in informal recycling centers in developing nations.
In these informal operations, workers often use rudimentary techniques such as burning or acid baths to extract metals, exposing themselves to dangerous toxins. These unsafe methods also lead to significant loss of valuable materials, reducing the overall efficiency of recycling efforts. It is a stark reminder that while some countries have made significant strides in e-waste management, much of the world still lags behind.
International organizations and governments are increasingly recognizing the urgent need to address the e-waste crisis. The Basel Convention, a global treaty aimed at controlling hazardous waste movements, has pushed for stricter regulations on e-waste disposal, promoting environmentally sound practices.
Collaborative initiatives, such as the E-Waste Coalition and the Global E-Waste Statistics Partnership, are working to improve data collection, recycling strategies, and policy frameworks to guide nations toward sustainable e-waste management.
Technological advancements are also helping improve the efficiency of e-waste recycling. New processes such as hydrometallurgy and bioleaching are making it possible to extract valuable metals more effectively, reducing the environmental impact of recycling. As these technologies evolve, they hold the potential to transform how electronic waste is processed globally.
With e-waste generation showing no signs of slowing down, the urgency for action on raw material recovery has never been clearer. Governments, industries, and international bodies must work together to invest in the infrastructure, technology, and regulations needed to properly manage electronic waste. By doing so, we can address both the environmental and economic challenges posed by e-waste, while moving towards a more sustainable, circular economy.
As the world grapples with the rising tide of discarded electronics, raw material recovery offers a solution that not only protects the planet but also delivers tangible economic benefits.
