“…The fraction of each product depends on the composition of plastics, type of reactor, temperature and heating rates (Bajus, 2011;Kluska, Klein, Kazimierski, & Kardas, 2014). The yield of liquid oil from the pyrolysis of waste plastics found in literature is reported to be more than 80% (weight) (R. K. Singh & Ruj, 2016;Wong, Ngadi, Abdullah, & Inuwa, 2015). The oil products can either be used as a feedstock for plastic production or as a fuel to run engines.…”

The current rate of plastic usage and the manner in which they are being disposed of is unsustainable. This is because more resources such as crude oil are utilized for their production and on the other hand, more waste plastics are generated. Since these waste plastics are made from crude oil, there is a high chance that they can be turned back into diesel that can be used to power irrigation pumps, drive engines for transport and industrial purposes among other potential uses. This paper sought to evaluate the pyrolysis of waste plastics to fuel oil potential of Uganda. The estimated waste plastics generated in Uganda was quantified as 545 851 kg/day. In this study, mass balance estimation indicated that the initial feed of 545 851 kg of waste plastics yields 451 419 kg liquid fuel using an appropriate technology for pyrolysis. The production potential of the gaseous and char fractions was calculated to be 50 764 and 43 668 kg in a day, respectively. This estimated amount has the potential to power approximately 234 small portable threshers of 5-7 horsepower. A total of 365 000 tonnes of fresh paddy can be threshed using these threshers. The gaseous fraction also has the potential to be used as a source of fuel for cooking. This is particularly important for postharvest handling and food security in Uganda as well as development of waste to energy technologies such as pyrolysis.

“…It is important to note that all the terms are of the same unit (kg). According to R. K. Singh & Ruj (2016), pyrolytic temperature and heating time are the factors that determine the quantity of char remaining in the reactor. Higher heating temperatures and times are associated with the reduction of solid residues in the reactor.…”

“…Plastic waste in particular, accounts for 20-30% by volume and 10-12% by weight of MSW, which makes it the third largest contributor after food and paper (Singh, 2016). Much of this plastic ends up in the world's oceans, where an estimated 5.25 trillion pieces of plastic are present, weighing close to 270,000 tons (Eriksen, et al, 2014).…”

“…Plastic production has increased over time as well, with literature reporting that plastic generation has increased from 1.5 million tons (MT) in 1950 to 245 MT in 2008(Singh, 2016. This is due to its convenience in manufacturing and variety of applications in packing, agriculture, automobile industry, construction materials, electricity and electronics (Pinto et al, 1999;Singh, 2016).…”

“…LDPE was used as the waste plastic source for field trials due to its availability in the test area, however, the other plastics listed above have been validated in numerous laboratory studies (Singh and Ruj, 2016, Demirbas, 2004, Pinto, et al, 1999. The chemistry of converting plastics such as LDPE waste to a hydrocarbon fuel oil is simple and well established (Singh and Ruj, 2016, Demirbas, 2004, Pinto, et al, 1999, Al-Salem, et al, 2009, Miskolczi, et al, 2004, Wong, et al, 2015, Panda, et al, 2010. LDPE, is produced via high-pressure, high-temperature free-radical chain-growth addition polymerization of ethylene, which is originally obtained from steam cracking of higher hydrocarbon oils, such as crude oil.…”

An Appropriate Technology Based Solution to Convert Waste Plastic into Fuel Oil in Underdeveloped Regions

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.

Comparative Analysis of Catalytic Cracking and Hydrocracking of Waste Plastic

Waste materials from various processes comprising of polyethylene and polystyrene were analyzed for the production of fuel using catalytic cracking and hydrocracking in an autoclave reactor. The composite catalyst USY/SBA‐16 was synthesized in the lab to be employed in the catalytic process because of its outstanding stability and regenerative capability. Each of the two processes produced a fuel with different quality and quantity. Catalytic cracking and hydrocracking of polystyrene and polyethylene were investigated at different temperatures by varying the percentage amount of catalyst and it was found that polystyrene yielded a fuel of better quality as compared to polyethylene.
