- Description: This study evaluates the viability of pyrolysis technology as a treatment process for waste tyres with the aim of producing alternative fuel and other high value products. A financial model was formulated to evaluate the economic feasibility of this technology as an alternative disposal method. It was discovered that pyrolysis technology becomes more viable when there is guaranteed product off-takes at a given price. Further processing of the crude tyre oil and carbon black is important for production of consistent quality products. Gauteng province alone will require a capital injection of US $59.8 million to setup 14 waste tyres pyrolysis treatment facilities to treat 134,922 tons per annum of waste tyres with a potential investment return and gross margin of 29.79% and 34.59%, respectively. These facilities can produce up to 46.8 million litres per annum of refined tyre derived fuel at cost of $ 0.516/litre and other secondary value add products for local and export markets.

- Description: The work presented in this article investigated the effect of a Whale diesel filter on engine’s exhaust emissions, fuel consumption and performance. A stationary ADE 407T heavy duty diesel engine coupled to a hydraulic dynamometer was used to investigate the performance, fuel efficiency and emissions tests under controlled conditions in a laboratory.

- Description: The work presented in this article reviews the possible methods for removal of mercaptans from distilled rubber derived fuel. Distilled rubber derived fuel is a potential additive for diesel fuel; therefore reduction of sulphur compounds in this fuel is essential for application in compression ignition engines. Membrane filtration of distilled rubber fuel using 13-X molecular sieves has shown a significant reduction in sulphur content. It was observed that distilled rubber fuel can be effectively filtered via single pass to remove up to 53.67% of the fuel’s initial sulphur.
