Due to the geology of the quarry, which supplies raw materials exclusively for the cement manufacturing process, a significant quantity of material has to be moved to access its limestone reserves.
Over three million tonnes of material is excavated each year using an opencast strip mining technique.
Although progressive restoration follows this strip mining, the natural topsoils are sandy, stony and nutrient poor, making restoration to a good agricultural standard difficult.

We hope that the results of the trials will provide valuable information relevant to the whole quarrying and mining industry in the
