A project that highlights their novel way of thinking involved working with Severn Trent to upgrade their Strensham water treatment works in Worcestershire, UK. Severn Trent, a leading utility company, had set challenging efficiency targets.
However, all this needed to be done without disrupting the water supply to 350,000 customers. And they wanted the project completed in less than 88 weeks, which is pretty demanding for the water industry.
It was around this time last year that one of the big winners at the IChemE Global Awards 2013 – PROjEN – were collecting the Bioprocessing Award for their technology used to convert pig waste into energy.
The pig waste, combined with other food waste, was being used to produce biogas capable of generating the equivalent of around 1.2MW of electricity.
The electricity was exported into the local energy grid in Leicestershire, UK, to power an estimated 700 homes and reduce landfill waste by 18,000 tonnes each year.
In the UK, people outnumber pigs by more than ten to one, so one has to ask the question – ‘Can human poo be used in a similar way to provide a sustainable source of energy?’.
