Plastic waste bid to fuel hydrogen cars at Swansea Universitylunes, 24 septiembre 2018 Scientists have developed a way of turning plastic waste into hydrogen and hope it could one day fuel cars. It involves adding a light-absorbing material to plastic, placing it in a solution and exposing it to sunlight.Dr Moritz Kuehnel, from Swansea University’s chemistry department, said it could be cheaper than recycling plastic as any plastic can be used and it does not need cleaning. Plastic waste has been a hot topic since the BBC’s Blue Planet II aired. «There’s a lot of plastic used every year – billions of tonnes – and only a fraction of it is being recycled,» said Dr Kuehnel. «We are trying to find a use for what is not being recycled.
