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. 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.
Ownership
- 1912 to 1983 Aberthaw and Bristol Channel Cement Co. Ltd
- 1983 to 2011 Blue Circle
- 2011 to 2013 Lafarge
- 2013 to 2015 Lafarge Tarmac
- 2015 to Present CRH plc (owners of Tarmac)
The Process at Aberthaw
The following summary diagram is from Tarmac's website[2]:
Raw Materials
The primary raw materials are Blue Lias limestone and clay from the adjacent quarry and Carboniferous Limestone mainly from Glamorgan.
Waste Used on Site
The Aberthaw site waste return to the EA for the most recent year of 2018 showed the following wastes used on site, all of which were used for the primary purpose of substituting fuel requirements in the plant:
| Waste Class | Description | Tonnage Input |
|---|---|---|
| 10 01 02 | coal fly ash | 3,118 |
| 16 01 03 | end-of-life tyres | 6,826 |
| 19 12 01 | paper and cardboard | 6,900 |
| 19 12 10 | combustible waste (refuse derived fuel) | 2,408 |
The schematic below from the Tarmac website shows a summary of how materials are used on site[3]:
The PFA and Blast Furnace Lag 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.
