Trash made a “wonder material” – stumbling upon high-quality Graphene

Scientists have developed a new technique for turning almost any carbon-based deperdition into graphene flakes! A quick and cheap technique involving immense heating up of waste breaks the carbon bonds – later reconstructed as graphene for a millisecond.

From banana skins and car tyres to materials of huge positive environmental impacts!

The best way of reusing trash

This is a big deal!

The world throws out 30% to 40% of all food, because it goes bad, and plastic waste is a massive worldwide concern. It has been already proven that any solid carbon-based matter, including mixed plastic waste and rubber tyres, can be turned into graphene, but existing graphene-producing processes resulted in either low-quality graphene or high-quality graphene in low volumes.

From nanoparticles to graphene

Today, the scientists have been able to develop a technique that gets a decent amount of the good stuff, in a faster time, and at a lower cost.

At the centre of the operation is a method known as Joule heating – a quick jolt of electricity is used to generate intense heat. This process has previously been used by scientists to create metal nanoparticles.

An inexpensive way to heal the environment

Graphene can be generated inexpensively, meaning that it can be used in more places, such as the production of cars or clothes, in cement for binding concrete (we could use less concrete for building, and it would cost less to manufacture and less to transport).

The technique could convert materials like waste food, plastic waste, petroleum coke, coal, wood clippings, and biochar into valuable graphene.

Essentially, we’re trapping greenhouse gases like carbon dioxide and methane that waste food would have emitted in landfills. Graphene has already proved its worth in a host of applications, covering electronics, manufacturing, and cleaning up pollutants.
