ABSTRACT
The main aim of this work was to design, fabricate and evaluate the performance
of a small-scale solid waste pyrolysis waste converter reactor. The system s main ’
components were the furnace housing assembly, the reactor assembly, the piping
system, the heat exchanger assembly (cooling condenser) and the collection system.
The entire system is stainless steel due to its stability at high temperatures, with the
reactor holding a capacity of 440.48 kg/weight of waste solids. After design and
fabrication, the reactor equipment was subjected to extensive practical performance
testing each waste plastic and other solid biomass feedstock three times. The furnace
and reactor temperature were controlled at 200 ℃ to 700 ℃ depending on the
feedstock for 2 hrs at a constant rate increase of 20 ℃. The results obtained with the
equipment showed a functional experimental conversion efficiency of 83.6 %, waste
reduction efficiency of 86.6 %, and an oil recovery level of 845 ml/kg of waste.

1. INTRODUCTION AND BACKGROUND
Due to the increase in energy consumption of fossil fuels as shown in Figure 1 [1], and the
continued depletion of natural energy sources in recent years, the research community has
focused on energy usage with the objective of improving efficiency and co-combustion and
developing renewable energy sources which this research and work is focused on. One such
source is waste biomass such as plastic waste, waste tyres, wood and other solid waste which
can produce fuel as a result of pyrolysis.
