Plastic waste may soon prove to be something more than an eye sore and an environmental hazard. Scientists at Swansea University discovered a way to convert plastic waste into hydrogen fuel that could one day power cars. It involves adding a light-absorbing material to plastic, placing it in a solution, and exposing it to sunlight.
According to the research, the process could also be a cheaper alternative to recycling as the plastic does not need to be cleaned first.
“There’s a lot of plastic used every year – billions of tonnes – and only a fraction of it is being recycled. We are trying to find a use for what is not being recycled," said Dr Moritz Kuehnel, head of Swansea University's chemistry department, in an interview with The Independent on the breakthrough.
