Zero-waste mobile phones come closer to reality

ANI  |  Washington D.C. [U.S.A.] 

Researchers have hit a milestone in a quest to safeguard the environment and reduce the e-as much as possible.

The scientists at the University of perfected a process to efficiently separate and resin - two of the most commonly discarded parts of a cellphone - bringing them closer to their goal of a zero-cellphone.

It's one of the first processes to use simple techniques like gravity separation to cleanly lift organic resins from inorganic

"Discarded are a huge, growing source of electronic waste, with close to two billion new sold every year around the world and people replacing their phones every few years," said "The challenge is to break down models that can no longer be reused into useful materials--in a way that doesn't harm the environment."

Most e-recycling firms focus on recovering useful metals like gold, silver, copper, and palladium, which can be used to manufacture other products. But nonmetal parts like and resins, which make up the bulk of cellphones' printed circuit boards, are generally discarded because they're less valuable and more difficult to process.

They're either fed to incinerators or become landfill, where they can leach into groundwater, soil, and air. Holuszko was determined to find a better recycling solution.

"The key here is gravity separation, which efficiently separates the fiberglass from the resin by using the differences in their densities. The can then be used as a raw material for construction and insulation. In the future, if we can find a way to improve the quality of the recycled fiberglass, it may even be suitable for manufacturing new circuit boards," said

The study appears in the journal Waste Management.
