PRESENTED FOR “TECHTOP- ENGINEERING PROJECT CONTEST-09” SCOPE OF THE PROJECT IN THIS SCENARIO OUR PROJECT AIMS TO SOLVE THE TWIN PROBLEM OF ENVIRONMENT POLLUTION DUE TO PLASTIC AND THE NEED FOR AN ALTERNATIVE FUEL SOURCE . SCOPE OF THE PROJECT THE MAIN AIM OF OUR PROJECT IS TO FIND A SOLUTION TO THE MOUNTINGS PROBLEM OF PLASTIC DISPOSAL , FOR WHICH THE PLASTIC ARE CONVERTED INTO USEABLE FUEL . SCOPE OF THE PROJECT THIS IS LIKE CASHING ON THE POLLUTION ITSELF .THIS PROJECT IF IMPLEMENT CAN TURN THE TIDES GLOBALLY BY PROVIDING A LONG TERM SOLUTION FOR THESE PROBLEMS. INTRODUCTION PLASTICS HAVE BECOME AN INDISPENSABLE PART IN TODAY’S WORLD .DUE TO THEIR LIGHT-WEIGHT , DURABILITY ,ENERGY EFFICIENCY , COUPLED WITH A FASTER RATE OF PRODUCTION AND DESIGN FLEXIBILITY ,THESE PLASTIC ARE EMPLOYED IN ENTIRE GAMUT OF INDUSTRIAL AND DOMESTIC AREAS . INTRODUCTION PLASTIC ARE NON DEGRADABLE POLYMERS OF MOSTLY CONTAINING CARBON, HYDROGEN AND FEW OTHERS ELEMENTS SUCH AS CHLORINE , NITROGEN ETC..,. DUE TO ITS NON-BIODEGRADABLE NATURE ,THE PLASTIC WASTE CONTRIBUTES SIGNIFICANTLY TO THE PROBLEM OF MUNICIPAL WASTE MANAGEMENT . PLASTICS Plastics are natural / synthetic materials . They are produced by chemically modifying natural substances or are synthesized from inorganic and organic raw material. on the basis of their physical characteristics ,plastics are usually divided into thermosets ,elastomers and thermoplastics . These groups differ primarily with regard to molecular structure , which is what determines their differing thermal behavior .The following table lists the characteristics of the various types of plastics. THERE ARE THREE TYPES OF PLASTICS: Thermosets Elastomers thermoplastics THERMOSETS CHARACTERISTICS AND APPLICATIONS Thermosets are hard and have a very tight –meshed , branched molecular structure .curing proceeds during shaping , after which it is no longer possible to shape the material by heating . Further shaping may then only be performed by machining . thermosets are used ,for example, to make light switches. ELASTOMERS CHARACTERISTICS AND APPLICATIONS While elastomers also have a crosslinked structure . They have a looser mesh than thermosets , giving rise to a degree of elasticity . Once shaped , elastomers also cannot be reshaped by heating . elastomers re used for example , to produce automobile tires . THERMOPASTICS CHARACTERISTICS AND APPLICATIONS Thermoplastics have linear or branched molecular structure which determines their strength and thermal behavior :they are flexible at ordinary temperatures .at approx.120 – 180 0c, thermoplastics become a pasty/liquid mass . The service temperature range for thermoplastics is considerably lower than that for thermosets . The thermoplastics polyethylene [pe] , polyvinylchloride [pvc]and polystyrene are used,for example , in packaging applications Plastics offer a variety of environmental benefits . However, their production, applications, and disposal has many environment concerns . Plastics and the environment provides State – of – the – art technical and research information on the complex relationship between the plastic and polymer industry and the environment, focusing on the sustainability, environmental impact, and cost-benefit tradeoffs associated with different technologies. The contributors also focus on the effectiveness of recent technologies in mitigating environmental impacts,particularly those for managing plastics in the solid waste stream . Plastic and design engineers , polymers chemists , material scientists , and ecologists will find plastics and the environment to be a vital resource to this critical industry. RAW MATERIALS •Waste plastics. PROCESS DESCRIPTION: Take1 kg of waste plastics of some kind [ldpe,hdpe] cut it into piece and dry it . The waste plastic is put inside the reactor after drying it. The reactor must designed to withstand high temperature of about 3500c-400oc. It has an inlet at the top for collecting the vapour. Start the burner for heating the reactor and measure the temperature . When the temperature reaches 150oc the vapour start to come down to the Condenser. The heating is continued for about 11/2 hours till the vapour stop collecting. After 1 or 11/2 hrs the plastics are decomposed. At the time larger carbon molecules are break into smaller molecules. There is no need of using catalyst for the process. The top of the reactor inlet is connected with the spiral condenser where the vapours are condensed. Finally the fuel from condensed vapours are collected . Approximately 700ml of thermo fuel will be collected from per kg of waste plastics. Thermocouple is used to measure high temperature . . SAMPLE:THERMOFUEL FROM WASTE PLASTIC DESCRIPTION : Light Brown liquid with very pungent smell Aniline Point: 650c Carbon Residue : 0.725 Wt % Smoke Point :23 mm DISTILLATION RANGE AND CARBON NUMBER DISTRIBUTION Initial Boiling Point : 69 0 c Naptha Range 140 0 c : 18% Kerosene Range 140 0 c to 270 0 c : 61% Diesel Range : 270 0 c to FBP : 21% Final Boiling Point :345 0 c Corrosion is less. No need of engine modification. Residue can be used as paraffin wax. Less amount of residue and large amount of product. CONCLUSION The production of thermofuel from waste plastics is one of the better methods to save the environment profitably. The collected fuel had been tested in C.P.C.L.[REASERCH AND DEVELOPMENT] and the sample test result have been enclosed with this report which shows its stability in this world as a fuel. We here by conclude that our project will be a pillar to save the environment and source for fuel.
