Solid wastes are the inevitable production of the operations of various industries like construction Industry, Machines Manufacturing Units, Textile industry etc. In India the construction industry generates large amounts of waste, which can be composed of different origin materials, most of them classified as non-hazardous. Construction and Demolition waste (CDW) constitutes a major portion of total solid waste production in the world and most of it is used in landfills. Dumping of these construction and demolition waste in landfill causes contamination of soil, water and air from toxic substances. Research by structural concrete engineers has clearly suggested the possibility of appropriately treating and reusing such waste as aggregates in new concrete. The aim of this paper is to explore the separation process of CDW and further use of recycled aggregates from construction and demolition waste (CDW) in concrete mixes. A review of most recent research and legislation applied in India is developed regarding the production of concrete by using these recycled aggregates.

Septic system plays a major role in sanitary disposal activities. In developing country it is very essential for proper disposal of wastes for providing clean environment. In our country the government has adopted scheme, “CLEAN INDIA”,. For achieving this aim, the septic system is necessary to construct in each and every residential, commercial buildings and public areas. Septic tank systems are a type of simple onsite sewage facility.But groundwater pollution may occur and can create a problem. Usage of mobile septic tank can be helpful to avoid such problem. In this present investigation an idea has been arrived and the septic tank constructed by the way which have been tested for 10 days for decomposition using microbes. The term ‘septic’ refer to the anaerobic bacteria environment that develops in the tanks which decomposes or mineralizes the water discharged into the tank. The rate of accumulation of sludge is faster than rate of decomposition. So in our project we have used microbes for decomposition.In urban areas, construction of septic tanks are easier. But in rock exposures, the septic tanks cannot be constructed easily. In this paper, the problem is solved by giving an idea as solution by providing a “MOBILE SEPTIC TANK”. This will be helpful and eliminate such problems.
