Some glass factories have drilled and milled silica mixed with water, their treatment depends on precipitation, filtration etc. New concept for recycling of waste have paid attention to taking samples from different steps of traditional treatment, water evaporation of samples have been carried out. Investigation of attained powdered using EDX showed that, about 95.87% of sample was silica while particle size analyzer proved that it was not exceeding 73 micrometer. Silica powder mixed with Acrylonitrile Butadiene Rubber using miller and moreover thermal compression were performed to achieve maximum compatibility and constant thickness of the composite. Electron beam irradiation of the samples with different doses 25 and 100 KGy were carried out. Mechanical investigation using stress strain technique, showing that pure silica composite was more than waste silica composite of step one by small value. Thermal characterization was studied using thermal gravimetric analysis proved that improvement of the silica waste NBR composite than that of pure composite and also for electrical properties of the composite which have the same behavior. These results confirmed application of waste silica instead of pure one with NBR composites and management of environmentally problem such as water polluted with waste silica.
