Pee Power technology returns to Glastonbury Festival for fourth year

Posted on

Technology developed at UWE Bristol that converts urine into electricity is set to be showcased at Glastonbury Festival for a fourth year.

An installation of a large 40-person urinal will return to a prominent location near the Pyramid Stage to raise awareness of the system, which is being commercialised as announced last year and introduced to off-grid areas in the developing world.

The PEE POWER® system can turn organic matter such as urine into enough electricity to power lighting or charge mobile phones. At the same time, it sanitises urine and produces plant fertiliser as a natural by-product.

Energy produced at the event will power lighting in the urinal block at night, while a new feature ‘Pee to Play’ will see festival goers playing retro games on Game Boys powered by the system. Visitors can rate their PEE POWER experience via an electronic display and give survey feedback to academic staff available to explain how the technology works.

The PEE POWER urinals – among 5,500 toilets at the festival – have been a fixture at the event since 2015 and used by thousands of people each day. In previous years, they have powered information displays, and helped charge phones and provide urinal lighting.

Professor Ioannis Ieropoulos, Director of the Bristol BioEnergy Centre at Bristol Robotics Laboratory, said: “It’s a great pleasure to be welcomed back to this wonderful event for a fourth year and to be part of the festival’s environmentally-conscious sanitation campaign.

“There’s been much activity with our technology since our appearance in 2017, with the introduction of PEE POWER to schools in Uganda and Kenya supporting our aim to improve safety and sanitation in the world’s poorest communities including in refugee camps and slums. Our system is being refined and made more efficient, and for the first time we will be powering some of the applications directly, which means no batteries. We even hope to be generating surplus electricity, especially during the busiest times at the festival.

“As team of scientists, we’re hoping for greater interaction with the public this year and it’s the first time we’ll be recording public feedback on the system.”

Dr Xavier Walter, one of the main researchers in the team, added: “We hope our retro gaming exhibit will resonate with the audience and attract festivals goers to have a look at our technology and ask questions.”

Ahead of the festival, the microbial fuel cell technology will be demonstrated at a Family Day event at Heathrow Airport, where the system is being considered as part of a commitment from Heathrow and waterless urinal technology company WhiffAway to zero emissions and sustainability.

The team’s presence at Glastonbury is the result of a close collaboration with partners Oxfam, log cabin and garden building specialists Dunster House and WhiffAway in a collective effort to improve lives in refugee camps and areas of the world with no sanitation or electricity.

Chris Murphy, Owner and Managing Director of Dunster House, said: “It’s truly amazing what Ioannis Ieropoulos and his team have achieved over the past years. We feel proud and honoured to be part of this project every year since the earliest field trial back in 2015. From that single raised latrine placed outside the University, we are now providing a structure ready to accommodate up to 40 people. We’re glad to be back at Glastonbury 2019 collaborating in a life-changing project that can help people all around the world.”

James McLean, Group CEO of WhiffAway Group, said: “It’s an honour and a privilege to be combining our cutting edge technologies at this wonderful event. By putting our heads together we hope to continue making a difference to the wider community and help change the world for the better.”

The PEE POWER demonstration is the flagship research project of a formal partnership between Glastonbury Festival and UWE Bristol signed in 2017 focusing on sustainability projects including waste reduction and energy efficiency.

How PEE POWER® works

PEE POWER® is generated when microbial fuel cells (MFCs) work by employing live microbes which feed on urine (the fuel) for their own growth and maintenance. The MFC taps a portion of the biochemical energy used for microbial growth, and converts that directly into electricity or PEE POWER®. This green technology also cleans the urine so that the by product can be used as a crop fertiliser.

The Pee Power project is funded by the Bill & Melinda Gates Foundation.
