Trident Park reaches 1m tonnes milestone

Viridor and the Prosiect Gwyrdd (Green Project) partnership in Wales have announced that one million tonnes of non-recyclable waste, has been diverted from landfill and used to generate energy at the Trident Park energy recovery facility. 

The £220m Trident Park facility in Cardiff opened in 2015 and receives 350,000 tonnes of residual waste a year, with 172,000 tonnes from Prosiect Gwyrdd councils.

Tonnage at the plant is mainly made up from the Prosiect Gwyrdd partnership, which consists of Cardiff, Newport, Monmouthshire, Vale of Glamorgan and Caerphilly.

‘Strategic aims’

Matt Wakelam, senior responsible officer for the Prosiect Gwyrdd Partnership said: “The partnership was set up to find a long-term sustainable solution to waste that cannot be practically recycled and composted to ensure that we no longer needed to send waste to landfill.

“The partnership is delivering the strategic aims that have been set, as we now recover green energy from this waste, as well as ensuring that the two by-products from the process – bottom ash and air pollution control residue – are both recycled.”

Mr Wakelam highlighted how the Welsh Government had set out its blueprint on waste management in Wales through its Zero Waste Strategy. He explained: “Energy recovery with both combined heat and power is their preferred waste treatment technology for non-recyclable waste. I am pleased to announce that plans are continuing to deliver a district heating system from the plant at Trident Park, which will transform the plant into a combined heat and power facility. In energy terms alone, this will significantly improve the efficiency of the plant.”

Viridor commercial director, Paul Ringham, said the company was proud of the landmark achievement and how the relationship with Prosiect Gwyrdd was continuing to evolve.

He said: “Diverting a million tonnes of waste which cannot be recycled is an achievement which must be recognised. Taking this one step further and using this material to generate low carbon power and contribute to resource and energy efficiency is an important goal but we know there is still more we can do.”

Mr Ringham added: “Trident Park, like all the energy recovery facilities in the Viridor fleet, is a combined heat and power plant and we are delighted to be working with Cardiff City Council to ensure that the heat generated by Prosiect Gwyrdd’s non-recyclable waste will support a future Cardiff Heat Network.”

Shared values

“The success of this ongoing relationship is based on shared values”

Patrick Murray, Viridor’s head of contracts for the South West and Wales who worked with Prosiect Gwyrdd to develop the initial contract. He said: “The success of this ongoing relationship is based on shared values about attaching a real value to all waste, recycling all we can and putting the remainder to work through energy recovery and making a real contribution to the community.”

Mr Murray commented that Viridor was “equally proud” of the education work Trident Park had accomplished, hosting 5,567 visitors, with the plant also contributing to community life by distributing Community Fund grants worth £198,659 to local groups.

And, he highlighted the role of education regarding energy recovery, saying: “Together Viridor and Prosiect Gwyrdd have created a valuable and well-utilised education centre where future generations are taught the value of recycling as well energy recovery. It is here that many people hear about the waste hierarchy – and the need to reduce, reuse, recycle and recover – for the first time.”
