Industrial waste from granite sawmills in soil fertility

Brazil has large reserves of granite and great potential for its industrialization. However, the granite processing industries face problems with the generation of large quantities of waste, which cause environmental impacts. In order to do long-term work that respects the environment and human beings, several studies have been carried out on the reuse of this waste. Some of this material has been used for landfills in civil construction, as well as being applied as an alternative material in the manufacture of soil-cement bricks and refractory materials. Based on this, this book presents a study on the potential agricultural use of the tailings from the industrial activity of sawing granite blocks as a corrective for acidic soils, thus improving the chemical characteristics of the soil, and also as a source of nutrients for plants. Thus, this book presents the possibility of reusing this material in order to reduce the environmental impact generated by the granite processing industry, as well as offering an agricultural alternative for attributing value to the waste.
