Abstract
AbstractWaste plastic is not a naturally degradable material, which is spreading diseases and adversely affecting our environment. Despite its nondegradability, this waste is an efficient source of hydrocarbons. Polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP) contribute a major part to plastic-based wastes. Instead of burning and landfilling, waste plastic can be converted into value-added products. The efficacious disposal of this waste results in value-added products, such as carbon nanotubes (CNTs), combustible gases and liquid fuels. Waste management and recycling in this way are instrumental for the social, economic, and sustainable environment. CNTs and fuels from the plastic can be produced via arc discharge, chemical vapor deposition, catalytic pyrolysis and non-catalytic pyrolysis methods. Many researchers have reported the production of hydrogen fuel through pyrolysis of plastic waste, which is much more efficient and environmental friendly than traditional fossil fuels. Hydrogen is being taken as the fuel for the future. This chapter reviews the possible conversion of plastic waste into value-added hydrocarbons and fuels.
