Prof. Yogesh Kumar Tembhurne Asst. Prof. Department of Mechanical Engineering (B.E.R.I Bhopal M.P.) ABSTRACT In the modern world the responses has changes quickly due to the need of person and requirements. As we know that the consumption of plastic & polythene are increases day by day which is a serious issue of the time concerning to environmental effect. Over a 100 million tones of plastics are produced annually worldwide, and the used products have become a common feature at over flowing bins and landfills. Because Plastics have woven their way into our daily lives and now pose a tremendous threat to the environment For minimizing hazardous effect of this on environment so many steps has been taken by the scientist and research has going on in the support of that i am going to introduce a technique of pyrolysis by the help of which we can convert the plastic and polythene waste in a useful fuel. The waste plastics are subjected to distillation,, pyrolysis, thermal cracking and depolymerisation distillation to obtain different value added fuels such as petrol, kerosene, and diesel, lubericating oil etc and use as a normal fossil fuels in the vehicle which helps in two aspects of need. (i). It minimizes the hazardous effects on environment. (ii). It helps in to produce fuel and minimizes the fuel crisis in some extends. In my dissertation of fuel production through waste polythene and plastic with the help of ziolite as a catalyst in that first of all i prepare a mild steel closed air tight vessel having a lid on the top of it along with the hole which is attached by a long galvanize steel pipe then i filled the container up ¾ of its height with the waste plastic and polythene then by using external source of heater temperature of closed chamber is arises up to 300 o C-450 o C from room editor@iaeme.com
2 Parametric Optimisation of Generated Waste Plastic Fuel Parameters with The Help of Taguchi Method temperature on which the pyrolysis takes place which converts the waste plastic or polythene in useful fuel whose texture,odorcolor, and all other properties like flash point,fire point, cloud point, pour point, viscosity, are almost near to the petrol.after that the outcome fuel from a waste plastic or polythene is used as a normal fuel in a 100 CC bike and found the fuel gives more millage as compare to petrol about 6-8 km. Which increases the efficiency of the engine by 15-20%.& by using Taguchi Technique I optimize the various parameters which affects the production of plastic fuel.by using advance technique I found the catalyst is most affecting parameter whose contribution is % and second one is time12.93% and the least is time whose contribution is 9.09%.

Parametric Optimisation of Generated Waste Plastic Fuel Parameters with The Help of Taguchi Method, International Journal of Mechanical Engineering and Technology, 7(1), 2016, pp INTODUCTION Polymer Polymer are the natural or synthetic molecules that are composed of a large number of smaller monomers, which have reacted to form long chain. The most basic polymers are made from the same monomers the name of this substance is made by adding prefix Poly to the name of monomer. Polymers can be classified into a number of ways which are described below. Figure 1 Plastic materials are cannot be decomposed easily in a short period of time. These plastic wastes can be classified as industrial and municipal according to their origins; these groups have different qualities and properties. The level of waste plastic continuous increase it is generating environmental problems worldwide. classification of plastics includes high-density poly-ethylene,( High-Density Polyethylene Milk, detergent & oil bottles, toys, containers used outside, parts and plastic bags).low editor@iaeme.com
3 Raj Kumar and Asst. Prof. Yogesh Kumar Tembhurne density polyethylene (LDPE, Many plastic bags, shrink-wraps, garment bags or containers)., polypropylene and polystyrene. Also, plastics are classified by their chemical structure of the polymer's backbone and side chains. Some important groups in these classifications are the acrylics, polyesters, silicones, polyurethanes, and halogenated plastics. Poly Propylene. Refrigerated containers, some bags, most bottle tops, some carpets, and some food wraps. There are two main types of plastics: thermoplastics and thermosetting polymers. These waste plastic convert to useful oil and reduces the many problems increasing in world. METHODOLOGY Pyrolysis process for conversion of waste plastic into fuel: Pyrolysis is the chemical decomposition of organic substances by heating the word is originally coined from the Greek-derived elements pyro "fire" and lysys "decomposition". Pyrolysis is usually the first chemical reaction that occurs in the burning of many solid organic fuels, cloth, like wood, and paper, and also of some kinds of plastic. Anhydrous Pyrolysis process can also be used to produce liquid fuel similar to diesel from plastic waste. Pyrolysis technology is thermal degradation process in the absence of oxygen. Plastic waste is treated in a cylindrical reactor at temperature of 300ºC 350ºC.Now a days plastics waste is very harmful to our nature also fo human beings.plastic is not easily decomposable its affect in fertilization, atmosphere,mainly affect on ozone layer so it is necessary to recycle these waste plastic into useful things.so we recycle this waste plastic into a useful fuel. Taguchi Method: The method presented in this study is an experimental design process called the Taguchi design method. Taguchi design, developed by Dr.Genichi Taguchi, is a set of methodologies by which the inherent variability of materials and manufacturing processes has been taken into account at the design stage. Although similar to design of experiment (DOE), the Taguchi design only conducts the balanced (orthogonal) experimental combinations, which makes the Taguchi design even more effective than a fractional factorial design. By using the Taguchi techniques, industries are able to greatly reduce product development cycle time for both design and production, therefore reducing costs and increasing profit. The objective of the parameter design is to optimize the settings of the process parameter values for improving performance characteristics and to identify the product parameter values under the optimal process parameter values. The parameter design is the key step in the Taguchi method to achieving high quality without increasing cost. The steps included in the Taguchi parameter design are: selecting the proper orthogonal array (OA) according to the numbers of controllable factors (parameters); running experiments based on the OA; analysing data; identifying the optimum condition; and conducting confirmation runs with the optimal levels of all the parameters. Taguchi method the experimental procedure included experimental design by Taguchi method, welding materials, welding equipment and welding procedure. Taguchi method can study data with minimum experimental runs. In this paper, the design of experiment work can be decided by this method. Steps of Taguchi method are as follows: editor@iaeme.com

Taguchi created a transformation of repetition data to another value which represents measure of variation present. This transformation is Signal to Noise ratio. Thus Signal to noise ratio is measure of amount of observed variation present relative to the observed average of quantity of fuel, the results are analyzed first by calculating the signal-tonoise (S/N) ratio for each performance characteristics for each experiment. Calculating the average of S/N value for each factor and plotting them for each level editor@iaeme.com

Prof. Yogesh Kumar Tembhurne Pie chart for percentage contribution Pie chart for percentage contribution Catalyst Temperature Time Error RESULT AND DISCUSSION By heating the close combustion chamber with heater of two thousand Watt in a temperature range of 200 to 450 degree Celsius we get approx 560 ml fuel oil. By heating of combustion about 45 minutes the layer of oil appears on the water level. After two hour we get 500 ml of fuel oil. By using 10 ml of this fuel in 100 cc Bajaj bike its runs bike one minute at average speed of 45 km/h.it is concluded that the waste plastic Pyrolysis oil represents a good alternative fuel. CONCLUSION By using this fuel oil in 100 cc bike it increases efficiency of bike by 15 to 20% as compared to petrol used in the bike. Engine fuel with waste plastic oil exhibits higher thermal efficiency. By comparing the density of HDPE oil with petrol its gives approximately same value. Also comparing the density of LDPE oil WITH diesel oil its gives approximately same value. It could be concluded, that thermal pyrolysis of plastic waste leads to the production of fuel oil, valuable resource recovery and reduction of waste problem. Thermal pyrolysis of waste plastic waste has also several advantages over other alternative recycling methods. It has been shown that the conversion at lower temperature in the presence of catalyst into liquid is a feasible process. According to ANOVA analysis the most effective parameters with respect to percentage calibration is Catalyst, temperature, time contribution indicates the relative power of a factor to reduce variation. For a factor with a higher percent contribution, a small variation will have a great influence on the performance. The percent contributions of the plastic fuel parameters on the percentage calibration According to ANOVA this, catalyst was found to be the major factor (75.24) affecting the percentage calibration, whereas time was found to be the second factor (12.93 %),least one is temperature 9.09% editor@iaeme.com
