Conversion of plastic waste into oil fuel had drawn the attention of scientists for the removal of waste from environment as well energy recovery. Pyrolsis of plastic waste had become an important technique to produce plastic waste oil as new supply of energy and alternative to fossil fuel. This study aimed to design portable pyrolysis unit for the conversion of plastic waste materials into useful fuel products from local facilities. Different horizontal and vertical vessels from local materials were designed and used to convert plastic waste such as HDPE and PP into the so called plastic oil. The vertical reactor given better performance than the horizontal for producing oil. Yield around 95% were achieved. A 5-liter portable pyrolysis unit based on vertical reactor was assembled and equipped with condenser system, temperature control and collection jar. The unit was used to convert different waste into oil and then 500ml of the resulting oil was used as fuel to replace the traditional fuel of tuk tuk. Fortunately, tuk tuk traveled distance 30% more than the distance travelled by same amount of traditional fuel. The designed unit is suitable to be used anywhere if water supply is available using either electrical supply or cooker gas. The prototype can be easily scaled to suit end uses.
