Pyrolysis of plastic wastes to fuel oil with and without catalyst Baoying Shi‚ Yufeng Wang Guangdong Dongguan Quality Supervision Testing Center Dongguan，China Chengzhi Chuai School of Material Science & Chemical Engineering Tianjin University of Science & Technology Tianjin‚ China Abstract—Two types of waste plastics were used in this study: polyethylene (PE) and polypropylene (PP). This paper described pyrolysis of plastic waste materials with and without catalyst. The influence of the

INTRODUCTION Waste disposal Waste management is the handling of discarded materials. Recycling and composting‚ which transform waste into useful products‚ are forms of waste management. The management of waste also includes disposal‚ such as landfilling. Waste can be almost anything‚ including food‚ leaves‚ newspapers‚ bottles‚ construction debris‚ chemicals from a factory‚ candy wrappers‚ disposable diapers‚ old cars‚ or radioactive materials. People have always produced waste‚ but as industry

have an impact on the citizens around it. Soil gas migration can cause a four-fold elevation of risk for bladder cancer and leukemia among women reported a study at the New York Health Department’s website. The second form of waste disposal is incineration. This type of disposal releases many air pollutants to include admium‚ lead‚ mercury‚ dioxin‚ sulfur dioxide‚ hydrogen chloride‚ nitrogen dioxide‚ and particulate matter according to the Environmental Protection Agency. Gases such as sulfur dioxide

them after use? Is it worth the extra time and effort to put our cans in a separate bin for trash collection? Some of the benefits of recycling include: well-run recycling programs cost less to operate than waste collection‚ land-fills‚ and incineration; recycling creates 1.1 million jobs; and thousands of U.S. companies have saved millions of dollars through their voluntary recycling programs. Some of the downfalls to recycling include inconvenience and a sense of false security on the current

waste disposal can make these same patients become ill by contamination of the water supply and the release of toxic fumes. Typically‚ medical waste is put into a landfill or incinerated. The most widely used and cost efficient method is incineration. Incineration‚ however‚ can release harmful fumes into the environment. Chantale has a few ethical options but we will only focus on one which is whistleblowing; below we describe what whistleblowing is. What is whistleblowing? “Whistleblowing”

INTRODUCTION RECYCLING OF RESOURCES : Recycling is a process to change materials (waste) into new products to prevent waste of potentially useful materials‚ reduce the consumption of fresh raw materials‚ reduce energy usage‚ reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal‚ and lower greenhouse gas emissions as compared to plastic production. Recycling is a key component of modern waste reduction and is the third component

landfilling is still the most frequently used method of waste disposal in the US. Other important waste disposal methods include incineration‚ plasma gasification‚ and recycling. Incineration is a high temperature waste disposal method that includes combustion of waste materials where incinerators convert waste materials into heat‚ gas‚ steam‚ and ash. Incineration is very common waste disposal method in Japan. In United States this method is relatively rarely used. Plasma gasification waste

petrol‚ and diesel fuels. Therefore‚ it is possible to convert waste plastic into fuels. The non-catalytic pyrolysis process is the nearest technique to commercialization considering the collection and recycling processes of waste plastics. Unlike incineration or gasification‚ non-catalytic pyrolysis yield fuel that is almost equivalent to the fractionating column of diesel. The existing use of pyrolysis and the risks involved in it proves that the amount of individual scope was only used for the process
