SMA Mineral has long been a customer of Svensk Oljeåtervinning, and when the company was put up for sale it was a natural step for SMA Mineral to acquire the business. Swedish Oljeåtervinning is based in Västerås and collects waste oil from industries throughout Sweden. The oil is processed and then supplied to customers, including some of SMA Mineral’s own plants.
SMA Mineral’s lime works also use other fuels. One example is gas, which is a residual product from the production process at some of our customers in the steel industry. This is another good example of the environmentally sustainable reuse of energy. In addition, our lime products are widely used in environmental applications such as flue gas scrubbing, water treatment and for adjusting acidity levels in lakes and in agriculture.
