About us

Dunbar Plant


Welcome to Dunbar

Dunbar Cement Plant is a limestone quarry and cement works that generates around £8 million annually for the local economy through salaries, rates and contracts with local suppliers.

Limestone and cement

Limestone is the main raw material used to make cement, and this comes from our quarry at Dunbar. Our Dunbar Plant uses this limestone to produce cement, which is the most versatile building material in the world. It is essential for creating many aspects of the built environment on which we all rely, including homes, hospitals, and infrastructure in the highways, transport, and water sectors.

Our History

Dunbar has a long and proud history within the East Lothian community. The plant celebrated its 50 anniversary in 2013. Here are some of the highlights:

1963 Blue Circle built a cement plant in Dunbar, the only site in Scotland with sufficient raw materials for cement-making. The company took on 550 people when the plant opened, 90 per cent of them from the local area.
1980s A single, highly efficient kiln and landmark preheater tower replaced the three existing kilns, expanding the factory’s production capacity.
1990s A £35 million investment increased capacity.
2001 The site became part of Lafarge Cement UK.
2007 A £22 million gas scrubber is installed to halve emissions of sulphur and dust.
2008 Quarry operations were moved to the North East Quarry; the old North West Quarry was ‘retired’ and the restoration process started.
2009 - 2010 A £7 million investment programme ensured the Dunbar plant was fully up to date technologically.
2011 The site was selected to be the first in the world to pilot a brand new project to improve reliability and performance.
2013 Dunbar became part of Tarmac.

Health and safety

Protecting the safety, health and wellbeing of our employees, contractors and those around us is a core value of our business. We work in potentially hazardous environments so it’s important that everyone understands how to go about their jobs safely.


We believe that no task is so important that it can’t be done safely and through measurement and learning we can continuously improve our performance. Everyone working at Dunbar is expected to work in a safe, responsible manner and to challenge unsafe behaviour.

We give everyone on site a thorough induction so they know our behavioural expectations and how to stay safe. We are very careful to separate out traffic and pedestrian movements, and we undertake risk assessments before each activity so that we know the risks involved and can prepare for them.

We measure our safety record by recording everything from a Near Miss (Unsafe Act or Condition), First Aid Treatment, Medical Injuries, and incidents that mean someone has to take time off work, known as a Lost Time Injury (LTI), so we can learn and avoid them altogether in the future.

On site, everyone outside the office buildings must wear Personal Protection Equipment (PPE).

The Mineral Products Association’s (MPA) has a Safe Quarry hub where you can access further information.
