A deal to process and export residual waste overseas has won Pembrokeshire County Council an award.
The authority revealed earlier this year that, along with Ceredigion County Council, it had entered into an innovative contract which sees waste that cannot be recycled locally exported to Sweden from Pembroke Port.
As well as saving both councils over £350,000 a year, it has also created 11 jobs at Pembroke Dock.
The ground-breaking deal has now been officially recognised at the Annual Welsh National Procurement Awards in Cardiff.
The Collaboration Award was received by Dan John on behalf of Pembrokeshire County Council's environmental and civil contingencies division.
Dan was instrumental in setting up the Residual Waste Framework Agreement with Ceredigion along with support from private sector company, Eunomia.
Judges described the project as 'innovative' and 'groundbreaking.'
Richard Brown, the council's head of environment and civil contingencies, said the contract would also help boost recycling rates.
He added: "It provides a flexible, low-risk, value-for-money approach that enables us to divert waste from landfill in the short term, but avoids committing too much waste to incineration in the long term as recycling rates escalate."
At the same ceremony, the council's procurement team also won an award for their work in electronic procurement.
