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. Dunbar started manufacturing clinker in 1963 and up to 2015 had produced 38 million tonnes of clinker through 3 rotary kilns over this period.

Waste Used on Site
There is no waste return for the Dunbar site to SEPA available for the most recent year of 2018, but the following schematic and detail on the Tarmac website shows that the site used alternative fuels to substitute over 40% of its energy needs, focused on sewage sludge, liquid wastes and tyres. In early 2019 Tarmac reported the signing of an agremeent with local waste company Hamilton Waste and Recycling to supply SRF to the plant. The schematic below from the Tarmac website shows a summary of how materials are used on site[3]:
