About us

The Price family have owned and farmed at Gelliargwellt Farm since 1902. In 1973 Price and Company farming Ltd was formed. The company established itself as one of the major milk producers in South Wales. They now farm over 1000 acres and have a milking herd of 600 cows.

To reclaim old coal mining land for the growing dairy herd, the Price family diversify into quarrying and landfill. A disused quarry was re-opened for the extraction of Blue Pennant Sandstone. The first major contract was the construction of the A469 – Llanbradach by-pass. Waste from the site was brought in and the lorries took stone back to the site.


In 1996 Bryn Quarry Limited was established as a separate company. In keeping with emerging trends the recycling side of the business was developed. Recycling hardcore, soils and builders rubble.

In 2000 with the increasing recycling demands, wood and green waste was brought to the site; a recycling unit was developed on site. Green waste was converted into compost and soil conditioner. This is sold commercial to Local Authorities, Utility Companies, Landscape Gardeners and the General Public. Whilst the wood is shredded in to sawdust and used as animal bedding by local farmers and ourselves.

In 2004 we were successful in registering and being accredited with “PAS100” by the Composting Association. In 2005 a new company Bryn Compost Ltd (SE Wales Demonstration Facility) was set up in partnership with Wales Environmental Trust, Merthyr Tydfil C.B.C. and Torfaen C.B.C., in order to build the first In-Vessel composting unit in Wales.

Today to improving the environmental impact of our business we have established Bryn Power Ltd to produce renewable electricity thought solar panels and an anaerobic digester..


So far 2015 has been a busy year for all companies at Gelliargwellt. The cow sheds have had a major new redesign with an improved slurry system and bigger comfier beds for the cows.
Our new material resource facility has been completed, with the creation of 10 new jobs.
On top of all the other work, the construction of our AD plan has started.
