Albeit at the condition of one of the main world metal silicon producer, Brazil has still not been able to delineate a clear strategy for the multiple and complex problems involving environmental and sustainability questions for the production of this important material. Their understanding is urgent due to the world perspective of a huge metal silicon demand for solar photo-conversion energy generation using silicon-based solar cells. In this situation, Brazil will be one of the only countries in the world with such a capability for supplying the exploding demand of this strategic material. The QITS - Quartz Industrial Trade System program has been working on the new model of integration of the multi-disciplinary themes of quartz-biomass-silicon system along its complete materials life-cycle. It starts with the extraction and processing of natural resources evolving into the activity of fabrication of high technology artifacts. Environmental, social, economical, trading, and technological aspects are also analised. Some representative results of QITS for the development of alternative source of materials and innovative technologies to obtain metal silicon are presented.
