RECYCLING OF POLYETHYLENE WASTE MATERIALS TO USEFUL PRODUCTS VIA PYROLYSIS.

RECYCLING OF POLYETHYLENE WASTE MATERIALS TO USEFUL PRODUCTS VIA PYROLYSIS.

CHAPTER ONE 1.0 INTRODUCTION  

1.1 BACKGROUND OF STUDY  

Recycling is a dynamic process that restores the life cycle of a material. Also recycling refers to as a process of collecting and processing materials that would otherwise be thrown away as trash and turning them into a new product. Recycling as well reduce the consumption of fresh raw materials, energy usage, water and air pollution and lower green house gas emission as compared to a plastic production. (Roach John 2003).

Polyethylene plastic bags are petroleum-based so the manufacturing process releases harmful pollutants into the atmosphere. Some speculate that these emissions and other smog-related types of pollution accumulate over time in the atmosphere.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    Uioolk1

Countries and large corporations are beginning to realize the threat that these plastic bags pose to our planet. Many are proposing or have already enacted laws and taxes to decrease the use of polyethylene plastic bags. Many grocery stores are even rewarding customers for bringing reusable grocery bags as an alternative to these polyethylene plastic bags. Customers choosing not to use alternatives to plastic bags either find the alternatives are inconvenient or are simply unaware of the problem at hand.

Polyethylene recycling bags are currently being used all over the world but there is currently no environmentally friendly way to dispose of them.

The rate of consumption of plastic materials in the world is highly expanding, more waste plastics are generated. In past years, their generation amount in China becomes about six million per year, according to data from the National Institute of Environmental Research (Roach John 2005).

Typically, raw materials are manufactured into products for consumption. Leftovers are then thrown away. This linear process, from extraction of raw materials, to production, then consumption and disposal, has created a waste crisis.

To reduce this one-way flow of re-sources to overburdened waste disposal facilities, materials no longer needed or wanted can be remanufactured. (Roach John 2003).

1.2 AIM

The aim is to recycle polyethylene waste materials to useful products via pyrolysis.

1.3 OBJECTIVES

The objectives of this work are includes:-

(a). To collect the polyethylene waste materials (discarded water sachets plastic bottle )

(b). To carry out thermal pyrolysis of the materials at temperature of 300oC – 350oC

 (c). To monitor the quantity of fuel gas and hydrocarbon liquids evolved

1.4 SIGNIFICANCE OF THE STUDY

The significance studies of recycling polyethylene waste materials via pyrolysis are:

It serve as an economics important to the society or nations

The recycling of polyethylene waste materials to useful appear intervene with our consuming society where it will be hard to imaging in modern society today without plastic which have found amyriad of used in fields as diverse as household appliance, packaging, construction, medicine and electronic.

The recycling of polyethylene waste help in an industrial production of plastic and polymer products such as sachet water, plastic bottle, rubber paint, e.t.c. As sources of raw materials to produces other useful product from those polyethylene waste materials.

It helps in prevent waste pollutant from an environment.

1.5 SCOPES OF THE STUDY

The research is restricted to the recycling of polyethylene products, arising specifically from Low Density Polyethylene (LDPE). No attempt is made to suggest new production process. the study does not include of alternative materials.

How To Write Chapter Three Of Your Research Project (Research Methodology)

  • Methodology In Research Paper


    Chapter three of the research project or the research methodology is another significant part of the research project writing. In developing the chapter three of the research project, you state the purpose of research, research method you wish to adopt, the instruments to be used, where you will collect your data, types of data collection, and how you collected it.

    This chapter explains the different methods to be used in the research project. Here you mention the procedures and strategies you will employ in the study such as research design, study design in research, research area (area of the study), the population of the study, etc. You also tell the reader your research design methods, why you chose a particular method, method of analysis, how you planned to analyze your data.

    Your methodology should be written in a simple language such that other researchers can follow the method and arrive at the same conclusion or findings.

    You can choose a survey design when you want to survey a particular location or behavior by administering instruments such as structured questionnaires, interviews, or experimental; if you intend manipulating some variables.

    The purpose of chapter three (research methodology) is to give an experienced investigator enough information to replicate the study. Some supervisors do not understand this and require students to write what is in effect, a textbook.

    A research design is used to structure the research and to show how all of the major parts of the research project, including the sample, measures, and methods of assignment, work together to address the central research questions in the study. The chapter three should begin with a paragraph reiterating the purpose of research. It is very important that before choosing design methods try and ask yourself the following questions: Will I generate enough information that will help me to solve the research problem by adopting this method?

    Method vs Methodology

    I think the most appropriate in methods versus methodology is to think in terms of their inter-connectedness and relationship between both. You should not beging thinking so much about research methods without thinking of developing a research methodology.

    Metodologia or methodology is the consideration of your research objectives and the most effective method and approach to meet those objectives. That is to say that methodology in research paper is the first step in planning a research project work.

    Design Methodology: Methodological Approach

    Example of methodology in research paper, you are attempting to identify the influence of personality on a road accident, you may wish to look at different personality types, you may also look at accident records from the FRSC, you may also wish to look at the personality of drivers that are accident victims, once you adopt this method, you are already doing a survey, and that becomes your metodologia or methodology.

    Your methodology should aim to provide you with the information to allow you to come to some conclusions about the personalities that are susceptible to a road accident or those personality types that are likely to have a road accident.

    The following subjects may or may not be in the order required by a particular institution of higher education, but all of the subjects constitute a defensible in metodologia or methodology chapter.
