Overview

WikiWaste has used the website Cement Plants and Kilns in Britain and Ireland 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. Padeswood started manufacturing clinker in 1949 and up to 2015 had produced 31 million tonnes of clinker through 4 rotary kilns over this period.

• 1949 to 1968 Tunnel Portland Cement Co. Ltd
• 1968 to 1986 Tunnel Cement Ltd
• 1986 to 2009 Castle Cement Ltd (Rio Tino Zinc (RTZ) to 1989, Scancem to 1999, HeidlebergCement to 2009)

The Process at Padeswood

The process at the site is an air-separated precalciner kiln, supplied by FLS (FLSmidth) which allows for the burning of alternative fuels.

Raw Materials

The primary raw materials are Carboniferous Limestone from Cefn Mawr Quarry, with coal measure shale and colliery waste from the Llay Main colliery tip, moving to Bersham Colliery in the future.
