The project, part of Ravensdown’s plan to eliminate coal use by 2030, would mean locally supplied wood fuel would replace coal in the lime-drying process. "Heat from burning coal is currently used to dry lime on site before it is distributed to customers’ farms. "Knowing that we can continue to meet farmers’ needs while removing our biggest source of emissions at the quarry is a major step forward."
