The electrical and electronic devices industry is seeing a huge surge in the present-day scenario. We are increasingly becoming dependent on it. With the newest devices coming up now and again, it is also becoming difficult and costlier to repair old devices. Hence, the average consumer is discarding their gadgets every few years. Parallely, e-waste recycling industry is taking a shape, proving its worth in sustainability and climate goals.
According to a study, it was found that 95% of e waste garbage in India is handled by the non-formal sector. While only 5% is in the hands of the formal sector. More than 3000 units in and around Indian cosmopolitan cities ****are a part of the non-formal sector. Additionally, only around 22% of electronic waste is treated, while we generate about 1.6 million metric tons nationally. Innovative technologies in e-waste recycling, therefore, are the only hope for a greener future.
E-Scrap and the Hurdle Faced in Recycling It
E-scrap treatment methods that were traditionally used are becoming inefficient and outdated in today’s world.
- These methods rely heavily on labor, which puts them at a greater risk of health hazards.
- If consumers are not up-to-date with the correct methodologies, they may continue encouraging such a system.
- Poorly developed infrastructure or a limited number of recycling centers is another problem faced in recycling. Besides, improper disposal poses environmental risks.
New Technologies That Will Pave The Way to a Brighter Future
Beyond managing waste, innovative technologies address the challenges faced in e-waste recycling. A few of such cutting-edge advancements are listed below:
1. Recycling E-Waste using Chemicals
It uses chemical elements to recover metals. It works for metals and components difficult to break and separate otherwise. There are 2 types of chemical induced recycling, namely, hydrometallurgy and pyrometallurgy. Pyrometallurgy involves heating e-waste at high temperatures to obtain metals from it. Relatively, hydrometallurgy uses chemicals to leach out valuable metals. Since it uses low energy and low heat, it is considered to be a promising method.
2. Using Nano Particles
Creating nano particles (NPs) using nanotechnology and using it to separate valuable metals from the e-junk is an efficient way of recycling. Nano particles, have high reactivity and surface area regardless of their size and can stick to metal components by detecting them.
3. 3D Printing
3D printing can transform the electronics industry, thereby, greatly reducing e-waste. 3D printers may use recycled components and add them layer by layer, which can reduce the consumption of materials used, thereby reducing e-waste and the need for e-waste recycling. Not only this, it can create a large number of customized gadgets on demand, and lessen the dependability on storing an enormous number of products.
4. Tracing using Blockchain
It will prove to be of great asset as it can maintain track of data about each electronic device. Details that are essential to document such as production time, shelf time, and method of disposal, all can be stored quite easily and made available at the fingertips. This will promote organizations to follow ethical disposal practices and not dump their electronics into landfills.
5. Using Urban Mining
This procedure includes probing into the e-waste dumps to recover valuable metals. If done responsibly, it reduces the need for mining, and its risks such as depleting resources and harming the environment and the workers involved. Since metropolitan cities are the leading producers of e-waste, this method turns them into the hub of valuable resources. A proper strategy has to be in place before starting with urban mining.
6. E-Waste Recycling in The Closed Loop Way
This involves using outdated appliances and creating similar new ones by recovering and reusing the components. It is a very eco-friendly method and promotes the concept of circular economy. While designing an electronic product for the first time, manufacturers are thinking how to make it more sustainable.
7. Using Laser Induced Technology
We can use lasers in separation techniques for metals. It is a promising cost cost-effective technique that can separate and provide metals such as aluminum from their waste source in a short amount of time, that too in a highly pure state. Research is going on about laser technology and how by combining AI with it, we can automate the processes and maximize the benefits.
However, these solutions are advanced and are opted by the organizations that take care of your e-waste recycling on your behalf. One such organization is USH India Recyclers – an e-waste recycling company that operates globally and pan India, helping organizations to deal with its e-waste securely and sustainably.
Conclusion
As the need for the latest electronic devices is rising, so is the need for efficient e waste recycling techniques and services. By adopting innovative techniques listed in this article such as automated disassembly, advanced mechanical processing, AI-powered sorting, hydrometallurgy, and other such methods, we can create a more sustainable future for electronics and us.
