Cenin has recycled an old aircraft hanger on a former aerodrome site. We are adapting this old building to recycle industrial by-products into cement replacements which will help to reduce carbon emissions.

Our Recycled premises are at
Stormydown, Bridgend. Read more about our new location.

Plant erection underway
Progress continues on our trial production facility at Stormy Down. All the necessary equipment for the first phase plant has been secured and the erection of the plant is underway.

August 2007
Patent Approval
After fifteen years of detailed research and thorough testing the patent for our Celtic Cement Technology process was granted 29th August 2007, patent number GB2401104. The patent was applied for on 29th April 2003 and since that date we have been working on perfecting the process and applying it to a commercial scale enviromnent. Further testing on a diverse range of industrial waste materials has taken place in the meantime with fantastic cementatious properties being achieved.
June 2007
Development plans are progressing for our first
cement replacement manufacturing facility. Utilising the patented
technology developed by our technology arm Celtic
Cement Technology,
we are building a fifth scale manufacturing plant which will act
as a proof of concept facility on a realistic commercial scale.
By utilising Celtic Cement technology and harnessing the power
generated from our own Biogas plant we will be manufacturing a
cement replacement product on our own site by April 2008.
Cenin will be the first manufacturing unit to produce a cement replacement from industrial by-products using 100% renewable energy.
