“…However, several of major mono-alkenes in the C 4 -C 12 range of sample 1 and compounds in the C 4 -C 9 range of sample 2 were identified. The presence of mono-alkenes with carbon numbers from C 9 to C 12 can be explained by the fact that the municipal waste probably contains waste products from high-density polyethylene [18]. The content of individual mono-alkenes varied from <0.1% to 7.3% in sample 1 and from 0.1% to 1.3% in sample 2, respectively (Table III).…”

Summary. Liquid products produced from two different types of waste pyrolysismunicipal wastes and spent tyre wastes are investigated using gas chromatographymass spectrometry. This method has been applied for detailed identification of composition of the samples. The components were characterized in terms of their Kováts retention indices on a PONA capillary column. The obtained analytical data were successfully used for the characterization of the samples. More than three hundred compounds were detected. The liquid products were complex mixtures, composed mainly of C 4 -C 12 compounds. The examination of the selected m/z values very clearly indicates the existence of the different groups of compounds. With a lot of olefins content (31.9%), followed by aromatics (20.0%), paraffins (17.3%), and naphthenes (7.5%), it is described as the liquid product from pyrolysis of municipal solid wastes. The aromatic compounds in liquid product from pyrolysis of spent tyre wastes have the highest concentration (33.5%), and they are followed by naphthenes (28.6%), olefins (19.2%), and paraffins compounds (7.0%). The present study has shown that the pyrolysis of municipal waste and spent tyres can be used as a means for reduction of environmental pollution and production of liquid product which could be used as a fuel source.

“…The most attractive technique of chemical feedstock recycling is pyrolysis. Thermal cracking or thermal pyrolysis involves the degradation of the polymeric materials by heating in the absence of oxygen [7]. The effect of temperature and the type of reactor on the pyrolysis of waste plastics has been studied by different researchers.…”

 Abstract-This paper presents the study and experimentation of fuel oil production by conventional slow pyrolysis using plastic waste from a municipal landfill. The different proportions of liquid fuel produced from landfill plastic obtained by non-catalyst conventional slow pyrolysis were studied. The landfill plastic was collected from Warinchamrap municipality landfill, in Thailand. The investigation of recycling of model and waste products based on PP, LDPE, HDPE, and mixed plastic were examined using conventional slow pyrolysis and distillation methods. The experimental results show that the reactivity of conventional slow pyrolysis and distillation can be controlled by temperature, time, and energy. The various types of plastic found in the municipal landfill were converted into differing amounts of liquid fuel. PP was converted into 80% liquid fuel, LDPE 73% to liquid fuel, HDPE to 70% liquid fuel, and mixed plastic to 46% liquid fuel. The distillation liquid fuel included high-quality liquid fuels. The liquid fuels derived from the waste plastic found in the municipal landfill was similar to petroleum diesel oil.Index Terms-Conventional slow pyrolysis, pyrolysis, municipal landfill, waste plastic oil.

“…A branched homopolymer, LDPE is manly used for food packaging, grocery bags, housewares, and films (Chenier, 2002). Pyrolysis, heating of the plastic in the absence of oxygen, or as it is also referred to, thermal decomposition, is the most widely utilized approach for converting LDPE (Wong, et al, 2015), or any waste plastic, into fuel oil (Singh and Ruj, 2016, Demirbas, 2004, Pinto, et al, 1999, Al-Salem, et al 2009, Kumar and Singh, 2011, Miskolczi, et al, 2004, Panda, et al, 2010, Sarker, et al, 2012. Since, the molecules of this plastic are only made up of carbon-hydrogen chains, when thermally heated to temperatures of approximately 430°C (Wong, et al, 2015), the hydrocarbon chains break, decomposing the polymer, and yielding a hydrocarbon gas, which is then condensed to obtain the fuel oil product.…”

Along with population and urbanization in developing countries, the amount of municipal solid waste generated is also increasing. Although programs and initiatives to recycle and manage waste can often be found in the major population centers, these technologies are slow to spread to or are not yet present in the rural areas. Heavily populated urban slums are also lacking in the infrastructure needed to collect and manage trash, particularly plastic packaging. To address this challenge, the University of Kentucky Appropriate Technology and Sustainability (UKATS) research team has developed an appropriate technology based, sustainable solution to convert plastic from Municipal Solid Waste, such as High/Low Density Polyethylene, Polypropylene and Polystyrene into a valuable hydrocarbon fuel, suitable for underdeveloped or poverty stricken communities. The UKATS Processor is designed as a waste minimization solution specifically for underdeveloped communities, comprised of a simple, non-automated, multifunctional processor built using a wood fueled rocket stove as the primary heat source. This processor is designed using the principles of appropriate technology and sustainability and can be constructed using non-standard materials commonly present in rural or underdeveloped areas. This research focuses on utilizing plastic waste to produce a fuel oil product similar to kerosene or diesel in composition.
