The market for silicon has grown from 500 000 tons to 1 000 000 tons since 1980. The growth has accelerated during the last few years and the expected growth rate is now 5-8% for the foreseeable future. The industrial process for production of metallurgical-grade silicon has improved its efficiency and is currently operating close to the technical limits. The world community expects from rising industries that no aspects of human life should be threatened by industrial activity and that growth should be sustainable. The silicon industry is in a good position to become a winner. The raw materials to produce silicon are quite abundant on Earth and the products made out of silicon are needed in our daily lives and can even be used to produce energy. Our challenges are the high energy consumption in the carbothermic process and the waste created in the process itself and in the following conversion steps
