Waste cooking oil biodiesel is thought to be a more sustainably sourced<br>alternative to its fossil fuel counterpart and can aid in reducing cooking oil waste streams. The<br>Navigation Guide systematic review methodology tool was applied to analyse the hypothesized<br>question: Does the replacement of petroleum diesel with waste cooking oil biodiesel reduce<br>hazardous PM emissions in heavy duty vehicles? The study question was specified, evidence was<br>selected and the quality and strength of the overall evidence was assessed for both individual studies<br>and across the body of studies. Precise criteria and protocols were developed and followed<br>throughout the review process to ensure that a thorough evaluation of all data was completed. All six<br>studies that met the review inclusion criteria utilized six-cylinder direct injection engines. Although<br>the PM emissions were measured differently across the exposure continuum, there was an overall<br>PM emission reduction of 28% across the studies when petroleum diesel was substituted with waste<br>cooking oil biodiesel. The overall risk of bias across the studies was determined to be „low‟. Based<br>on the application of the Navigation guide methodology, it was found that the strength of the<br>evidence provided was „sufficient‟ to suggest an association between waste cooking oil biodiesel and<br>PM emission reductions</p>}, number={2}, journal={Proceedings of the World Conference on Waste Management}, author={Oshinusi, Omobolanle H. and Gray, George M.}, year={2019}, month={Oct.}, pages={01–14} }
