The objective of this project is to focus on the hydrobin employed in stage IV of NTTPS which not only give high efficiency but also reduce the harmful effects of ash ponds on the environment. Ash ponds are becoming a menace to the environment in many ways.
Ash pond failures, increased government regulations, growing demand for reuse of ash, etc are all forcing thermal power plants to reevaluate the ash-handling system and NTTPS is not behind in adopting these latest advancements. Hydrobin separates the bottom ash from water thereby avoiding ash ponds. The dry ash that is obtained can find their applications in various other industries while the water is recirculated in the plant. In the further pages we shall get an insight about what Hydrobin is, it's construction, it's working, it's advantages and defects.

Due to the rapid growth of population in many developing countries like India the disposing of solid waste is a major problem in our daily life. Solid waste management is one of the major environmental concerns. Among the waste material, plastic is the material that is the major concern to most of the environmental effects. There are different types of plastic which are classified on the basic of the physical property and how they react with the temperature. As the plastic waste is non-degradable, it must be recycled or reused. The objective of the study is to study the behaviour of the concrete which is made of the recycled plastic materials along with the study of the some of the physical properties that are related. Usually M20 grade of the concrete is the most commonly used in the constructional works, hence in this study M20 Cement concrete is considered in which the recycled plastic waste is used as the replacement of the sand in the concrete. Concrete cubes were casted taking 20% to 50 % of plastic as partial replacement of sand and tested for 7, 21, 28 days of the compressive strength. These test revealed that the optimum replacement of the recycled plastic material was 20% to 30% of the weight of the sand used in the concrete.Keywords
