Shale process

Where do Shale Blaes come from?

There was a rich shale oil history around West Lothian between 1851 and 1962. In its prime, the county had an annual output of over 3 million tonnes, which was mainly used for producing lubricating oils as well as paraffin for heating and lighting. As a result, there are plenty of bings dotted around the local area. Our own recycling facility has been built on the site of an old bing, which we restored when we took over the site back in 2017.


Brewster Brothers are the first aggregates producer in the UK to achieve an Environmental Product Declaration (EPD) for recycled aggregates. This has been independently verified by BRE Group. The impact of our EPD on our customers and the main contractors in their supply chains is that you now have access to accurate and transparent environmental impact data for your sustainability reporting.

Using the results from the EPD, we can provide you with accurate carbon savings for using our recycled aggregates versus the average for both virgin and other recycled aggregates according to the UK Government’s indices. Use our brand new Carbon Calculator to find out about the carbon you could save using our products.
