Recent decades continuous increased in the fuel price and fast depletion of the available fossil fuel reservoir, so it is necessary to find out the alternative fuel for the engine. The use of vegetable oils as a fuel directly in diesel engines causes some problems due to their high viscosity compared with conventional diesel fuel. Various techniques and methods are used to solve the problems resulting from high viscosity like preheating, blending, Esterification etc. One of these techniques is fuel blending. Find the best blend and add the ethanol in that blend in the 5%, 10% and 15% find the engine performance and emission characteristics. Engine performance and emission were investigated and compared with the ordinary diesel fuel in a diesel engine. Experimental results show that the engine power and torque of the mixture of sesame oil–diesel fuel are close to the values obtained from diesel fuel and the amounts of exhaust emissions are lower than those of diesel fuel. It is concluded that it is possible to use Sesame oil in diesel engines as an alternate fuel in the future without modification in the engine.
The conventional ways of breaking emulsions using heat is disadvantageous from both economic and environmental perspectives. In this study, the quality of virgin coconut oil (VCO) produced from the water soluble materials and centrifugation method of coconut milk from freshly harvested coconuts was investigated and the Separation and filtration of the oil from the cream after centrifugation. Analysis was carried out by HPLC (High Performance Liquid Chromatography). The oil recovery was about 25-30% of the volume of coconut milk. The oil was colourless, had natural sweet taste, and free from turbidity and rancidity. Its acid value (0.26-0.43 mg KOH/g oil), and refractive index at 40 oC (1.448-1.449) indicated good quality. Comparison of the fatty acid profile between VCNO and commercial grade edible coconut oil showed that VCNO had higher concentration of short and medium chain fatty acids and lower concentrations of long chain fatty acids than the commercial grade edible coconut oil.
The environmental impact of synthetic plastic wastes is of global concern as these are inert to the attack by the microorganisms. These persistent polymers are a significant source of environmental pollution and harm wild life when these are dispersed in nature. Therefore, recycling and degradations of plastics is an important issue for environment and economic reasons. Partially biodegradable polymers obtained by blending biodegradable and non biodegradable commercial polymers can effectively reduce the volume of plastic waste by partial degradation. They are more useful than completely biodegradable ones due to the economic advantages and superior properties, imparted by the commercial polymer used as a blending component. Pure starch does not form a film due to hydrophilic nature. This article gives an excellent account of the recent research and developments on starch based plastic films. The article is very informative for the researcher, academicians, business strategist, and environmentalist for their effort in reducing the pollution from these wastes and for sustainable growth using natural resources.
