CSSDS is based on sand fixation technology and water-saving technology, focusing on biological sand consolidation to rebuild ecological environment with different reconstruction technology. Applying suitable measures to local conditions and to promote desert economy. At the same time, CSSDS is aiming at developing sustainable sand fixing agent that owns chemical and biological techniques to develop a stereo treatment system.
