Community Impacted by Industrial Estate Odours
Families living near Granville Industrial Estate, a rural area close to Dungannon in County Tyrone, have reported feeling confined within their homes due to persistent and unpleasant odours they attribute to the industrial site.
Colette Casey, a resident of Eskragh near Dungannon, has voiced concerns for several years regarding the "unbearable smells" emanating from the estate. She and other local families express feelings of abandonment as their quality of life has deteriorated due to these odours, prompting calls for stricter regulatory measures.
Data obtained by NI reveals that over the past five years, local authorities in Northern Ireland have received more than 10,000 complaints related to bad smells. However, fewer than 60 enforcement actions have been recorded during this period.
Colette described how the intensity of the odour varies depending on factors such as wind direction and time of day.
"After a long day at work, you want to go outside but sometimes the smell is so bad it makes your eyes water and stings the back of your throat, to the point you have to close the windows of the house and you feel trapped in your own home,"
Most complaints were directed to local councils, with the Belfast, Newry, Armagh, Mid Ulster, and Causeway Coast and Glens council areas registering the highest numbers.
Notably, complaints in Mid Ulster tripled between 2021 and 2025, yet the council did not issue any enforcement notices during this time.
Mid Ulster Council stated it investigates "all odour related reports received in line with relevant legislation."
NI has previously reported on odour problems affecting communities in Killeeshil, Warrenpoint, and Artigarvan.
Residents can lodge complaints about odours through several channels in Northern Ireland, including local councils, the Northern Ireland Environment Agency (NIEA), and the Health and Safety Executive for Northern Ireland (HSENI).
Industrial Estate Operations and Odour Challenges
Granville Industrial Estate hosts over 20 businesses, encompassing factories involved in food processing, agri-business, meat processing, cold storage, and bio-waste energy production.
Colette noted that over the last decade to decade and a half, increased factory activity has coincided with worsening odour issues, significantly impacting residents' quality of life.
"Sometimes it's a very strong chemical like smell, other times it's a sort of decaying and rotten like smell, both are hugely unpleasant."
She also highlighted the difficulty in pinpointing the exact source of the odours due to the number of factories operating in close proximity.
Freedom of Information data indicates that nearly 400 complaints were made to the NIEA regarding factories within Granville Industrial Estate between October 2020 and October 2025. Approximately half of these complaints concerned the Granville Ecopark (GECO) factory, which processes renewable energy and food waste.
Further figures provided by the NIEA in response to an assembly inquiry show that odour was detected during 50 inspections at GECO between 2021 and 2025.
The NIEA also confirmed four condition breaches at GECO from 2019 to 2025, two of which led to enforcement actions related to odour issues, including odour detected off-site.
On 8 May, the NIEA received notification from GECO about "the release of an odorant that had been detected on their site." This odour, described as smelling like gas, was reported in the village of Eglish, located more than three miles away.
A GECO spokesperson stated the company takes its regulatory responsibilities seriously and is investing significantly to ensure the site operates to the highest standards.
"When an issue is identified, we have worked quickly to resolve it and liaised with NIEA in line with our obligations as a regulated site,"
Similarly, the NIEA reported four condition breaches at Dunbia, a meat processing company based in Granville, between 2019 and 2025. These breaches pertained to monitoring and air and water emissions.
Dunbia responded by affirming its commitment to environmental responsibilities and noted substantial investments at the site.
"Opportunities for improvement are continuously assessed in conjunction with NIEA and further targeted investment is scheduled in the coming months,"
said a company spokesperson.
Ministerial Briefings and Official Responses
Documents released to NI provide additional insight into the odour challenges at Granville.
A briefing prepared by Stormont advisers ahead of a ministerial visit to GECO in July 2022 detailed hundreds of noise and odour complaints. The document noted the complexity of the situation due to the proximity of multiple operators, making it difficult to identify the precise sources of noise or odour issues, which appear to be contributed to by several operators.
In a statement to NI, the NIEA acknowledged receiving odour reports related to various regulated sites within Granville and stated it is monitoring the situation to ensure compliance with permit and license conditions.
Friends of the Earth NI commented on the odour complaint data, highlighting concerns about the trend.
Director James Orr remarked that while 10,000 complaints may seem substantial, they likely represent only a fraction of the actual impact.
"There are probably lots of people from these communities who got fed up with no action being taken, and stopped complaining,"
"Especially when you consider how low the enforcement actions numbers are compared to the complaints, that raises legitimate questions about that effectiveness of the statutory agencies.
People can sometimes be dismissive about odour issues, but if you live in those communities impacted by it can feel like being hostages in your own home."
The NIEA stated it will continue collaborating with other statutory bodies regarding odour issues and will take appropriate enforcement action when necessary.
