The Government's spending watchdog has called on Irish hospitals to boost their recycling efforts and improve the way they manage waste.
John Purcell, the Comptroller and Auditor General, said hospitals would face massively increased waste bills in the future if they failed to implement change.
Mr Purcell said Irish hospitals were producing around 27,500 tonnes of waste annually and spent €15.5m annually on disposal.
He said it cost €1,430-a-tonne to deal with potentially hazardous waste and between €140 and €450-a-tonne to have non-risk waste collected.
