Background
At Severn Trent and throughout the water industry, a number of complex biological processes are used to treat wastewater and safely return it to the environment. However, these biological processes can emit greenhouse gasses (GHG) specifically methane (CH4) and nitrous oxide (N2O) as by-products.
Challenge
Severn Trent’s aim is to reduce/remove our direct (scope 1) GHG process emissions from across our treatment processes, whether through process optimisation, covering assets and extracting greenhouse gases or even replacing assets and implementing new processes to reduce overall emissions.
Severn Trent are looking to hear from innovators & universities that have proven/tested methodologies, asset bases and/or theories that can be delivered over the next 1-5 years. Of which a £ figure can be applied covering purchase of materials/assets and implementation, to be compared with total tonnes of CO2e saved.
Asset bases include:
Wastewater Recycling: Sewage Network, Sludge Holding Tanks, PSTs, Transfer chambers, ASP lanes, Trickling Filters, Sand Filters, RBCs
Bioresources: Digestors, Secondary digestors, Cake Storage, storage tanks, liquor treatment, sludge thickening
What's in it for you?
The UK water industry has committed to be Carbon Net Zero by 2030, demonstrating a clear commitment to tackling climate change and Severn Trent is looking to lead on new technologies/ processes and assets that will help us meet this goal. Collaborating with Severn Trent in this area, delivering measurable reductions in process emissions could result in a commercial contract with Seven Trent, but it will also give the successful innovators a platform to showcase the assets/ technologies/ new processes to the rest of the industry.
