Changes to the environmental permit of a controversial waste plant have been approved by Natural Resources Wales (NRW).
The plant, on Nine Mile Point Industrial Estate, in Cwmfelinfach, has faced fierce opposition after Caerphilly County Borough Council approved it in 2015.
While the plant is not yet operational, one of the companies behind it – Drumcastle Limited – has now been given permission remove an onsite dryer from the original plans.
Earlier this year, council planning officers approved a request made by Hywel NMP – the other company behind the plant – to remove the dryer. Its original purpose was to dry shredded waste, but this is no longer needed.
Belfast-based Drumcastle Limited will operate the site on contract from Hywel NMP and has been granted an environmental permit from Natural Resources Wales. This covers the treatment of non-hazardous household, commercial and industrial waste for it to be burned to generate electricity.
What is the waste plant and who is behind it?
Plans for the new waste treatment facility on Nine Mile Point Industrial Estate were approved by the council’s planning committee in December 2015.
Hazrem Environmental Ltd, the company initially behind the waste plant, previously said up to 100,000 tonnes of waste would be processed annually at the site, including the sorting and segregating of waste for recycling and the production of fuel.
Campaigners have previously argued that council officers should have asked Hazrem to carry out an environmental impact assessment before the decision was put to the council’s planning committee.
In not doing so, council officers rendered “any subsequent planning consent unlawful”, the Lower Sirhowy Valley Residents Group has said.
In early 2021, the site of the proposed waste plant was sold by Hazrem to its directors, who in turn sold it to Hywel NMP.
Hywel NMP was set up in January 2021 and is backed by private equity investment firm Foresight Group, which is based in the Shard in London.
An application was submitted by Hywel NMP to Caerphilly County Borough Council in 2021, which proposed removing the dryer from the plans. This was approved in early 2022.
However, an application to make these changes was also submitted to NRW and has since been approved. This was submitted by Belfast-based company Drumcastle Limited – which holds the environmental permit from NRW.
Drumcastle Limited is the company which will be running the plant under contract from Hywel NMP.
Drumcastle Limited wanted to alter the permit to include the changes to the dryer and the use of a carbon filter to stop smells from the site – which has now been approved.
The decision was made by NRW following public consultations, held in April and September this year.
Campaigners had expressed concerns over the removal of the dryer. One of those campaigners, Dr David Platt, previously suggested its removal could see heavier treated waste going out of the plant, resulting in more lorries going in and out of the industrial estate.
While those behind he plant have argued the removal of the dryer would reduce potential odours, Dr Platt has said the removal of the regenerative thermal oxidiser (RTO) from the plant alongside the dryer could potentially create an odour problem.
What is a regenerative thermal oxidiser (RTO)?
An RTO is a commonly-used technology used to control air pollution in chemical plants.
It destroys air pollutants that can be created in chemical plants. The RTO breaks down the pollutants at a high temperature, combining them with oxygen before releasing them into the atmosphere.
They are regularly used to tackle fumes and odours.
Another issue Dr Platt was concerned about is a new system which could be installed at the plant to replace the dryer.
Dr Platt said the system will be provided by German firm Stadler. This is the same as the system used in a similar plant near Heathrow Airport, where an eight-metre wall had to be wrapped around it to reduce noise.
NRW “satisfied”
NRW has now said it is “satisfied that the company can make the changes without adversely impacting on local people or the environment”.
The environmental body also said the a range of assessments, including noise and odour pollution, had been considered in the application.
Jon Goldsworthy, Operations Manager for NRW, said: “Having looked carefully at the information provided in the application and consultations, we are confident that the variation to the permit meets the legal requirements, and the operator can carry out the activity without significant risk to the environment or human health.”
Campaigners “won’t be giving in”
Ynysddu councillor Jan Jones, who has been a prominent campaigner against the waste plant, said she was “disappointed” by the news and vowed not to stop the fight.
Speaking to Caerphilly Observer, Cllr Jones, who is an independent, said concerns over odours, noise and lorry movements still persist.
She said the community had been “let down” by both the council and NRW, the latter of which she accused of being “not interested in the health and wellbeing of residents”.
Cllr Jones said campaigners, including her fellow ward councillor Janine Reed, will get together to discuss the news but insisted: “We won’t stop the fight. We’re going to be watching them all the time.
“We won’t be giving in. We will be making complaints if things aren’t done properly.”
