Castle is to start its six-month trial in March 2005. It will use MBM to provide up to 50% of the fuel needs of Ribblesdale's most modern kiln. This equates to around 34,000 tonnes of MBM a year.
Lafarge Cement is looking to undertake a six-month trial burn of MBM at its Aberthaw works. The Agency is carrying out the final stages of public consultation over the proposal, and may give the go-ahead in November.
Lafarge hopes to start the trial next year, using MBM to replace 30% of the fuel mix - equal to over 20,000 tonnes of MBM annually.
