Abernant was developed by the National Coal Board as one of the West Wales "super pits" alongside Cynheidre Colliery in the Gwendraeth valley, an investment intend to keep economic coal mining a viable industry in the area.
[1] The £10million development began in 1954, with the sinking of two of the deepest shafts in the coalfield to allow access to the Peacock anthracite seam.
Production started two years later, with coal extracted along the Amman Valley branch of the former Llanelly Railway and Dock Company, and on to the mainline at Pantyffynnon.
In September 2011, Waste Recycling Group Ltd submitted plans for the development of an anaerobic digestion facility on the old colliery site.
Proposed to run on food waste collected from 350,000 homes in Bridgend, Carmarthenshire, Neath Port Talbot, Pembrokeshire and Swansea, the 2.3 MW facility would be capable of generating enough electricity to meet the demands of approximately 5,000 homes, and producing fertiliser.
