The research is related to solving the problem of rational use of materials and to creation of resource-saving technologies for the protection of the environment from pollution by various pollutants. Sorption technologies are quite effective in sewage treatment, but most sorbents are quite expensive, and their regeneration raises the question of recycling of spent solutions. The cheap and availability of raw material base of biosorbents makes these technologies attractive for wastewater treatment. The research is aimed at investigation of ways to effective utilization of spent sorbents, which are obtained after water purification, in the production of building materials. The obtained results allow create a complex low-waste technology of water demineralization and purification from heavy metal ions.
