Ultra Light Rail Partners have received £60,000 ($81,393) from the government’s Sustainable Innovation Fund to help develop a train that runs on biomethane (human waste).
Biomethane is a type of biofuel derived from several waste products, including sewage sludge and food waste. To create the fuel, these waste products are fed to bacteria that break them down to produce a gas that can be used as a cleaner alternative fuel.
The Independent reports that ULR is developing a railcar that could replace city trams and will be capable of carrying 120 passengers. More specifically, the new railcar will reportedly feature ultraviolet lights and heavily filtered airflow.
