There is a growing awareness in India about extensive damage being caused to the environment due to accumulation of waste materials from industrial plants, power houses, colliery pits and demolition sites and it has become one of the major environmental, economic and social issues. Waste material is the material unused, unwanted and rejected as worthless into the environment in our society as whole. Waste materials coming out of industry nowadays is posing a great environmental problem in disposing them into the air, water and on the land. But, with proper utilization of these materials in construction industry as well as in making road pavements will greatly help the society to have a better and pleasant environment. Substitution of waste materials will conserve dwindling resources, and will avoid the environmental and ecological damages caused by quarrying and exploitation of the raw materials. The aim of this study is to explore the possibility of re-cycling plastic waste material that is now produced in large quantities in the formulation of bricks as admixture. Looking forward to the environmental condition, complete ban on plastic cannot be made. Our present work is helping to take care of these aspects. Plastic waste, consisting of carry bags, cups and other utilized plastic can be used as an admixture in manufacturing of bricks. In this work an attempt has been made to manufacture bricks by using waste plastic in range of 60 – 80 % by weight of laterite soil and 60/70 grade bitumen was added in range of 2 – 5 % by weight of soil in molten form. And this bitumen- plastic resin was mixed with laterite soil to manufacture the bricks.

The uses of this special stretcher are, to transfer medicines for hospital and give freedom to the retired person or paralyzed patients to move anywhere on flat surface as well as stairs. We are in the process of development of a tri-wheel stretcher that has several new features than existing wheel and track based on universal stair for all place. A Three-wheel functions as ordinary wheel on flat surface, but has the ability to climb automatically when a defect to rolling is encountered. This wheels are consists of three tires, each wheel is on separate shaft. These shaft are located on vertices of an equilateral triangle. These triangular sets of wheels can neglate many types of terrain, rocks, sand and mud. It can also allow a vehicle to climb on small obstructions such as rocks, holes, and stairs. The wheels can also be gear-driven, two wheels are on rolling contact with the ground. The third wheel is at the top til the lower first wheel hit an obstruction. The obstruction prevents the lower front wheel from moving forward but it does not affect the motion of the driving axle. So, the top wheel is rolling forward into position as the new front wheel. This wheel usually lands on top of the obstruction and give the rest of the assembly to vault over the obstruction. Using of this stair vehicle, the human labor cost can be reduced as well as huge amount of loads can be transferred with less power consumption.

The increase in demand for refrigeration globally in the field of air-conditioning, food preservation, medical services, vaccine storages, and for electronic components temperature control led to the production of more electricity and consequently an increase in the CO2 concentration in the atmosphere which in turn leads to global warming and many climatic changes. Thermoelectric refrigeration is a new alternative because it can reduce the use of electricity to produce cooling effect and also meet today’s energy challenges. Therefore, the need for thermoelectric refrigeration in developing countries is very high where long life and low maintenance are needed. The primary objective of this portable solar thermoelectric refrigerator cum cooler is to provide a comparatively low cost alternative to existing cooling systems. Refrigerators in the confines of our homes are too traditional, besides a portable refrigerator with a cooler which runs on solar energy as an alternative is a better choice. As a developing civilization, we have been consuming large amounts of energy for our survival and the non-renewable sources of energy are depleting. Solar energy is widely available as compared to other renewable energy sources. The system will utilize solar energy, where supply of conventional electricity is not dependable. Comparison has been made based of existing systems and feasibility. The system works on Peltier effect. Thermoelectric Modules are incorporated for space cooling application. The cold side of the thermoelectric modules is utilized for space cooling, and the heat generated in the thermoelectric modules is removed using heat sinks and an arrangement of fans. The coefficient of performance of the system is a criterion for evaluating the performance of the cooling system. An effort has been made to enhance the COP using a combination of solar cells and thermoelectric modules. The system is compact, which makes it portable and it can be customized and fabricated to meet different user’s requirements. The problem with traditional refrigerators have been, high consumption of electricity, negative impacts on the environment, all these problems have been addressed by the thermoelectric cooler. It does not make use of refrigerants thus ensuring a green and eco- friendly technology for space cooling applications. The absence of Compressor leads to noiseless operation and lowered maintenance cost. It is an energy efficient initiative, consuming less power. For generations rural India does not have a dependable supply of electricity. Being highly reliable alternative it is intended for use in these places.
