Largest of its kind AD facility opened in York

A new next-generation anaerobic digestion (AD) facility, said to be the largest AD facility of its kind in the world, has been opened in York.

On 14 August, it was announced that System-60 – a set of 60 five-litre automatically fed, temperature controlled anaerobic digesters in the Department of Biology at the University of York – was now officially open. It has been funded by Yorkshire Water (YW), who is working with the University to optimise the facilities and provide YW with data to finetune the entirety of its AD fleet.

University researchers will monitor Yorkshire Water’s recent refurbished pilot AD facility at the Naburn Waste Water Treatment works, as well as managing System-60 on campus.

Professor James Chong, leading the research for the Department of Biology, said: “The goal of the project is to increase the conversion of solid material into gas so that more sewage sludge can be processed using the same facilities, reducing the need to build more infrastructure. System-60 will be used to screen conditions and the pilot rig will then be used to demonstrate the benefits of the best conditions at a larger scale to build a case for operational changes within YW’s business.”
