== | ==Overview== | ||
{{ | WikiWaste has used the website Cement Plants and Kilns in Britain and Ireland<ref>https://www.cementkilns.co.uk/index.html</ref> extensively for the reference material for each individual cement kiln page. The detail on this reference website is extensive and as WikiWaste is focused upon the UK waste and resource market, only the key highlights are captured from this website (and company websites accordingly) to provide background and context. Aberthaw started manufacturing clinker in May 1914 (with only [[Rugby]] being older in the UK) and up to 2015 had produced 33 million tonnes of clinker through 6 rotary kilns over this period. | ||

The Pulverised Fuel Ash (PFA) and Blast Furnace Slag shown in the diagram are not classified as waste by the producer, but as a feedstock for cement production and so tonnages are not reported to the [[EA]]. | |||
