Summary site information collated from a variety of sources.
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.

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 was last updated on Oct-24. The total reported tonnage arriving at the site was: 120,784.97t.
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.
