Work has started on a world-first project lead by Northumbrian Water which will see domestic sewage turned into fuel for aircraft.
A team of research experts from Northumbrian Water are currently developing the ground-breaking project, which will transform algae grown in domestic sewage into sustainable aviation fuel.
Named the “Green Machine”, the innovation will see experts using algae to extract nitrogen and phosphorous from wastewater, recover it and then convert it into sustainable fuels.
The project, which has used a £6.5 million investment from the water company, will help to reduce environmental impacts of waste treatment and will save up to £1 million per year in operational costs.
Northumbrian Water is leading the development of the project to scale up the algal treatment of wastewater and is working with partners at American-based company, BrightWave, and filtration experts at Liqoflux.
It is hoped that the Green Machine will be trialled at Bran Sands Treatment Works, in Teesside, by the summer of 2025.
Angela MacOscar, Head of Innovation at Northumbrian Water Group, said:
“The Green Machine is set to revolutionise the way we treat waste, and we are incredibly excited that we have started work on this brand new project.
“With our ‘Power from Poo’ project, where we create green energy using the sludge that is left over from wastewater treatment, we have already shown that we are leading the industry in pushing the boundaries of innovation – and this is set to be carried forward with this project.
“Not only will this help to develop a value-added product, but it will also help to boost us forward towards our own net zero goals and help us to achieve our net zero ambitions.”
Tim Shaw, President at BrightWave, added:
“BrightWave is thrilled to support Northumbrian Water in this innovative and important project. It will be one of Europe's largest indoor algae-based initiatives and a model for future applications.
“We're excited about how this venture's integration of wastewater treatment, SAF development and a low-cost profile will position it as a viable and relevant worldwide solution."
