PRINCE Charles visited Gwynedd for a tour of a new green energy plant.
The prince this week visited Biogen’s GwyriAD anaerobic digestion plant at Llwyn Isaf near Caernarfon - the first of its kin in Wales.
Richard Barker, Chief Executive of Biogen, said: “We are delighted that His Royal Highness took the time to have a personal tour of the plant.
“We hope that we demonstrated to him why Biogen is the UK’s leading specialist in anaerobic digestion.”
The five million plant will convert 11,500 tonnes of household food waste into renewable energy every year.
It will generate enough electricity for 700 houses annually, which is enough to power nearby Penygroes.
The anaerobic digestion process also produces a nutrient-rich biofertiliser, which will be used to help Gwynedd’s farmland.
Biogen are also in the process of developing anaerobic digestion plants at Waen, Rhuallt, near St Asaph, and at Bryn Pica in Rhondda Cynon Taf.
His Royal Highness was greeted at the plant by Biogen Chairman John Ibbett, Nick Ross of Iona Capital, and Gwynedd Council Chairman Cllr Huw Edwards.
The prince, who visited the plant as part of his summer tour of Wales, also planted an autumn spire rowan tree.
