The increasing global waste plastic pollution is urging people to take immediate actions on effective plastic recycling and processing. In this work, we report the results of processing reclaimed plastic wastes from unsanitary landfill site in Kuwait by using a bench scale continuous auger pyrolysis system. The plastic feedstock was characterised. After a simple thermal densification process, the material was fed to the pyrolysis system at 500 °C. The pyro-oil and wax products were collected and characterised. The process mass balance was developed on dry basis, and the yields of pyro-oil, light wax, heavy wax and gases were 5.5, 23.8, 69.4 and 1.3 wt%, respectively. The findings have indicated that the reclamation of plastic waste from landfill was feasible in terms of the product distribution and characteristics. Further liquid analysis confirmed that the liquid products contained fractions that are comparable to petrol and diesel fuels. The wax products are viable and have potential application as coating, covering and lubrication.

The problem of plastic waste is very flourished in the current era of modern life.  In this study, a three-condenser pyrolysis reactor was applied to obtain fuels in the form of oil#1, oil#2, and oil#3 from plastic waste. Gas Chromatography-Mass Spectroscopy (GC-MS) technique was carried out to analyze the fuel for profiling study.  Characterization using GC-MS indicated the domination of hydrocarbon compounds was found oil#1.  The existence of hydrocarbon compounds from oil#2 and oil#3 was displayed by chromatogram and MS database from Library Wiley 7.LIB.  Meanwhile, alcohol, ether, and fatty acid were detected from oil#1 based on the chromatogram and MS database.  Therefore, the samples were categorized as fuel.  The result of this study corresponded to the concept of pyrolysis and be able to be implemented as an alternative energy source. Keywords: fuel, GC-MS profile, plastic waste, three-condenser pyrolysis reactor

This paper presents the design of a fixed bed reactor pyrolysis to convert plastic waste type LDPE into condensate oil. The dimensions of the batch type pyrolysis reactor are adapted to household needs and are designed to be easy to operate and transport. From the results at three different pyrolysis temperature variations; 250 oC, 275 oC and 300 oC shows that reactor yields a maximum condensate oil of 45,3wt% at temperature of 300 oC. In addition, the weight of charcoal also decreased along with the increase in operating temperature.

Fuel Pyrolysis

The increasing use of plastic makes plastic waste the number one contributor to environmental damage in the world. The type of plastic that is most often found as waste is Polypropylene (PP). One way to overcome this problem is to convert plastic into liquid oil, which can be used for various purposes in the chemical industry or as an alternative fuel. Pyrolysis is a technology commonly used to convert plastics into liquid oil, and can be done by the public. But the availability of pyrolysis reactors that are easy and safe to operate is something that needs attention. In this research, a pyrolysis reactor with a capacity of 1 kg / batch has been modified from a gas cylinder. The pyrolysis process was carried out at 250°C, 275°C, 300°C, 325°C and 350°C with a reaction time of 120 minutes. The results showed that pyrolysis at 350°C can produce the highest yield of 62.56%. Through testing using Gas Chromatograpy-Mass Spectroscopy it is known that the liquid oil obtained consists of several groups of compounds or derivatives from Hexane, Heptane, Isotridecanol, Dodecana, Cyclohexana, Benzene, Pentane, and Octana.

The study being reported here was conducted to convert plastic waste,a major source of solid pollution in Pakistan, into liquid fuel by application of Thermal Pyrolysis. A pyrolysis reactor consisting of high strength Pyrex round bottom flask was constructed in the laboratory and used for converting plastic waste into liquid fuel. A 280g sample of plastic waste was pyrolyzed and the resultant products were 120g liquid oil, 100g solid residueand 60g gas.Thus, the yield of liquid fuel from the plastic waste was 43% wt. along with solid mass 36%wt. and gas 21 % wt. The results clearly indicate that there is a significant potential of producing liquid fuel from plastic waste in Pakistan andthe world.

Astola Island is the first marine protected area of Pakistan acknowledged 2017, June 15. It is a rich biodiversity hotspot, Ramsar site inhabiting endangered species like Green turtle, Hawksbill turtle, and Arabian Humpback whale. A saw-scaled Russell’s viper is endemic to Island. Marine ecology of Astola Island is affected by plastic pollution resulting in coral destruction, ocean acidification, global warming, fishing nets blockage, water pollution, and coastal erosion. Zeolite catalyst synthesized from environmentally friendly way by coal fly ash to degrade collected plastic waste from Island into useful products in pyrolysis reactor. The synthesized catalyst functionalized further with three type of organosilane(1) Octyltriethoxysilane(OS),(2)Phenyltriethoxysilane(PS)(3)Vinyltriethoxysilane(VS).Zeolite functionalize with octyltriethoxy silane (ZO) shows the highest performance in plastic pyrolysis, resulting in lower degradation temperature, low residue and more product formation may be due to having long chain hydrocarbon and acidic sites. Plastic recycling is the promising solution to tackle plastic blooming issue. Which is negatively impacting all the compartments of ecosystem especially marine environment.

In the present work, the pyrolysis of polypropylene and polyethylene was evaluated with and without the addition of niobium oxide as catalyst by means of thermogravimetric analysis and experiments in a glass reactor. The results revealed that niobium oxide performed well in the pyrolysis of both polypropylene and polyethylene separately. For the mixture of polypropylene with polyethylene, the catalyst reduced the pyrolysis time.
