A few years ago are being studied methods that use agricultural waste to acquire chemicals with the highest market value as pulp for making paper and other cellulose derivatives. This work includes the systematic review regarding the pulping organosolv applied to lignocellulosic waste fibers in various matrices and their availability and low cost one factor that makes the use of such residues an attractive alternative. The development of processes organosolv collaborates with reduced environmental impact of conventional delignification processes. These lignocellulosic materials have three basic constituents: cellulose, hemicellulose and lignin, and are found in plant biomass, forests, agricultural/ agro-industrial products. The purpose of chemical pulping is to remove lignin without degrading the cellulose chain that shall provide appropriate properties to their subsequent use, thus there is no doubt about the importance of organosolv pulping for companies seeking clean alternatives to new technologies
