Demand for renewable energy sources is increasing day by day. The rapidly increasing population and energy needs on a global scale have increased the number of studies on renewable energy sources. In addition to energy needs, the search for disposal and storage of wastes harmful to the natural environment is of great importance. Disposal and storage requires high costs and labor. The need for energy and the necessity of protecting the natural environment provided the solution to convert wastes into energy or value added products without damaging the environment. The wastes of the crops produced as a result of agricultural production can be converted into energy or value added products. Some of the plant wastes meet the energy needs and some of them can be used in the production of value-added biomaterials. Biomaterials are materials which are used in the field of health and show bioactivity with parts such as organs and tissues. Bioactive glasses, which are one of these materials, are used in the health sector especially in dental filling, prosthesis and composite applications. The most important feature of raw materials to be used in the production of bioactive glasses is SiO2 (silica). Plants receive silica from soil during development and this silica is also present in plant waste. In this study, a wide literature review was conducted and the percentage of mass ash after burning of rice stalks, corn stalks, hazelnut shells, corn stalks which were firstly burned for heating and energy purposes were determined. Then, the composition of the ash obtained SiO2 (silica) and other substances were determined and all the results obtained in the light of this information was compiled to provide information about the possibilities of use in bioactive glass production.
