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[2])
The Process at Cauldon
The following summary diagram is from the Aggregate Industries website[3] which is a 'dry process':
Raw Materials
The primary raw materials are Carboniferous Limestone from Cauldon Low Quarry to the south of the site and Carboniferous Shale in a nearby deposit to the north and west of the plant. The query SELECT "epr","ewc","descr","tin" FROM "db_ea"."ea_desc_in" WHERE epr='TP3334AW' is invalid (Error : SSL SYSCALL error: EOF detected
Function: EDConnectorRdbms::fetch Query: SELECT "epr","ewc","descr","tin" FROM "db_ea"."ea_desc_in" WHERE epr='TP3334AW' ).
Waste Tonnage, EWC List
The table shows a list of the Waste for the Permit TP3334AW, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data was last updated in October 2024. The total reported tonnage arriving at the site was: 120,784.97t.

Waste Tonnage, By Origin
The table shows a list of the Waste for the Permit TP3334AW, that has arrived into sites as reported to the Regulator and then publicised in their reported statistics. The Data used is from the most recent returns. The total reported tonnage arriving at the site was: Expression error: Unexpected < operator.t.
Where this tonnage exceeds that reported in year of the corresponding annual report, this may be due to the following reasons:
- Tonnage may have been received but not incinerated, i.e. the material is held pending incineration (the operator return to the EA reports as received whereas the annual report focuses on when the waste is incinerated.)
- Material may have been received into the site but treated in some other way than incineration.
- Material may have been received on the but transferred out of site for disposal/treatment at another site rather than incineration on the site.

In early June 2021 Aggregate Industries confirmed that they had broken ground on a £13m project to increase their ability to handle up to 100,000 tonnes per annum of waste derived fuel from early 2020[4]
