Hong Kong Government officials travelled more than 2,000 miles to see how a sewage treatment works in the Bradford district will create its own electricity.
Members of the state’s drainage team came to see the UK’s first BioThelys Sludge Treatment Plant which will be used to create energy from human waste.
The 750-acre sewage works at Esholt is one of Yorkshire Water’s largest facilities, serving 700,000 people and receiving up to 300 litres of waste water a second which it treats before discharging into the River Aire.
Project manager at Yorkshire Water Simon Balding said: “It makes sense that other countries are interested in this fantastic technology which will save us more than £1.3 million a year on electricity costs at this site alone, and just shows that what we’re doing at Esholt really is leading the field.”
Around 26,000 tonnes of bi-product sludge is produced at the site each year. Yorkshire Water is pioneering sustainable route for sludge disposal.
