From the Thames Tideway Tunnel to schemes such as the HS2 rail line, London Heathrow’s third runway and a possible Crossrail 2 project underneath London, the UK’s infrastructure pipeline dominates the headlines – good and bad.

Aalborg Portland in Aalborg, Denmark, has been using solid recovered fuel (SRF) for many years. The SRF is burnt in the pre-calciner on a grey cement kiln line. Substitution rates have grown over the years and are currently at approximately 45%.

To overcome some operational issues, Aalborg Portland recently purchased a new bale-opener from fellow Danish firm ReTec Miljø ApS.
