Converting plastic waste into combustible gas through the downdraft-type fixed bed gasification system is an effective approach to plastic waste disposal that is both cost-effective and environmentally friendly. This type of gasification system is capable of producing syngas that consists of carbon monoxide, carbon dioxide, hydrocarbon, hydrogen sulfide, oxygen, and water vapor. It is found to be more effective in reducing the mass, nutrient, and moisture content of various kinds of organic waste, as well as producing significantly lower tar levels than the updraft-type gasification system. The generated syngas from both used- and unused-plastic-waste RDFs can be directly used in internal gas combustion engines. Additionally, the HHV (Higher Heating Value) of the syngas from unused plastic-waste RDFs is slightly higher than that of the used one. This technology is considered a clean alternative to fossil fuels and helps to reduce the amount of waste going to landfills. The pilot-scale downdraft type fixed bed gasification system is a viable and sustainable solution to plastic waste management. It is highly cost-effective and provides a stable, environmentally friendly approach to convert plastic waste into combustible gas. This technology can provide a reliable source of fuel, reduce the amount of plastic waste going to landfills, and help to reduce dependence on fossil fuels. As part of its mission to reduce waste, the Green Warrior® has implemented an innovative approach to manage non-biodegradable plastic waste. This cutting-edge technology allows for the successful recycling of virtually all inorganic waste into materials that can be used in many ways.
