Uses
To extract the limestone used to produce lime in Bedford, it is necessary to first remove large quantities of black slate overburden, amounting to approximately 1 million tons a year. Because of the low amounts of limestone contained in this overburden, it cannot be used in the lime production process and there are very few alternative uses for the slate.
It is from this inert, natural material that the new Regional Park and green space will be created.
