Cardiff Energy Recovery Facility (ERF) is the largest ERF in Wales treating waste from local authority and local business contracts. The facility, which has been operational since 2014, handles 350,000 tonnes of residual waste (non-recyclable) waste, per year. It diverts at least 95% of South Wales’ residual waste away from landfill and generates 30MW of electricity for the national grid. That is enough to power around 50,000 households.

172,000 tonnes of the waste treated at the facility is delivered by the five Councils that make up the Prosiect Gwyrdd (Project Green) partnership: Cardiff, Newport, Monmouthshire, Vale of Glamorgan and Caerphilly. As well as treating household waste on behalf of Prosiect Gwyrdd, the facility alsos receive non-recyclable waste from other contracts, helping local businesses to divert their waste away from landfill. 

More than 1.6 million man-hours were spent on the project between 2012 and 2014 and with only one lost time accident during the entire project; it is rated among the safest construction projects worldwide.

The plant has been awarded R1 status which officially certifies that the ERF is operating at, or in excess of, the energy efficiency threshold required to be officially classified as an Energy Recovery Facility, as opposed to a disposal facility. Trident Park ERF is operating around 35% above the energy efficiency threshold required to achieve this certification.

Engaging with the wider community about the need for energy recovery technology, working in partnership with the waste hierarchy to reduce, reuse and recycle waste is important. At Cardiff ERF we have invested in an environmental education (visitor) centre to encourage people to learn more about the process. Our full time education officer would be happy to show you around.
