Overview
WikiWaste has used the website Cement Plants and Kilns in Britain and Ireland[1] 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. Cauldon started operating in 1957 and up to 2015 had produced 40 million tonnes of clinker through 4 rotary kilns over this period.
Ownership
- 1957 to 2001 BPCM (G&T Earles) (Blue Circle)
- 2001 to 2013 Lafarge
- 2013 to 2015 Lafarge Tarmac
- 2015 to Present LafargeHolcim (Lafarge Cement is part of Aggregate Industries, which itself is owned by LafargeHolcim)
