The world is undergoing the largest wave of urban growth in history. Increasing urbanization, growth of population with rising standards of living have contributed to increase the quantity of solid wastes generated by mining, industrial, agricultural, and domestic activities. Management of increasing amounts of solid waste has become a major challenge in many cities in developing countries. The main objective of waste management system is to maximize economic benefits and at the same time protection of the environment. The optimal solution for solid waste management is to minimize the quantity of waste both at generation and disposal stage followed by preventive environmental management action. Recycling of solid wastes is another major productive area in which considerable quantity can be utilized for manufacturing new products. Converting solid residues into value-added materials not only alleviates the disposal problem but also converts a waste material into a marketable commodity. The major solid wastes generated in Brazil are ash generated at coal-fired power plants, sludge from water treatment plant and waste biomass. To safeguard the environment, efforts are being made for recycling the wastes and utilize them in value-added applications. This article provides an overview of current research activities of our research group on the synthesis of value-added materials from Coal Combustion Products and waste agricultural biomass and their potential environmental application especially as low-cost adsorbents for the treatment of wastewater and production of ecological brick.
