Waste management company Viridor has been appointed as the preferred bidder for a £233 million project in Cardiff, Wales.

The Trident Park Energy Recovery Facility project is jointly run by four councils – Rhondda Cynon Taf, Merthyr Tydfil, Blaenau Gwent and Torfaen – for a long-term solution for treatment and disposal of waste.

The 25-year contract, which may be extended for a further five years, will begin in April 2016 and is backed by funding from the Welsh Government.

Viridor will process around 95,000 tonnes of residual waste annually into low carbon energy.

Ian McAulay, Chief Executive of Viridor, said: “Through our £223 million investment at Cardiff, Viridor is helping nine Welsh authorities deliver a low carbon vision for transforming what once was ‘waste’, generating renewable energy from what remains.”
