Plastic trash disposal is becoming more of a global issue as a result of industrialization and population growth. Waste disposal is one of Nigeria’s most serious issues. Such garbage is made up of polymers and plastics, which have been found to be challenging to treat in studies. Inadequate waste management in Nigeria is exacerbated by the country’s higher population density. Plastics are low-cost, lightweight, and long-lasting materials that may be easily molded into a variety of items for a variety of applications. One of the most essential measures currently accessible to decrease these impacts is recycling, which is also one of the most dynamic areas in the plastics business. A permanent solution is now available because to recent developments in pyrolysis research. The goal of this study was to design a plastic pyrolysis densifier for producing building materials such as pavers, floor tiles, solar roof tiles, and fence posts using plastic as a feedstock. By fabricating a pyrolysis machine, billions of kilograms of plastic might be saved from landfills and transformed into oil, resulting in an environmentally friendly and profitable solution to plastic waste. The plastic densifying machine is made up of five major components: a hopper, a screw driver, a barrel and nozzle (die), heaters, and a control system. The nozzle and barrel are the main components of the machine, via which the crushed particles are sucked into liquid. The barrel containing the screw (mixer) is the device’s core component, with its length heated by the gas burner. A heating control mechanism regulates the heat used to melt the crushed plastics. The molten plastic is conveyed to the barrel opening by a motor-driven screw.
