Abstract
Background: The Navigation Guide developed by Johnson et al was used to conduct a robust systematic review of six experimental intervention studies looking at particulate matter (PM)emissions from conventional petroleum diesel and a biodiesel alternative utilizing waste cooking oil in heavy-duty petroleum diesel engines. Waste cooking oil biodiesel is thought to be a more sustainably sourced alternative to its fossil fuel counterpart.
Objectives: Application of the Navigation Guide systematic review methodology to answer the question: Does the replacement of petroleum diesel with waste cooking oil biodiesel reduce hazardous PMemissions? Methods: The study question was specified, evidence was selected and the quality and strength of the overall evidence was assessed both for the individual studies and across the body of studies identified. Precise criteria and protocols were developed and followed throughout the process of the review to ensure that a thorough evaluation of all data was completed.
Discussion: Six investigative experimental studies were identified that met the inclusion criteria. All studies utilized six-cylinder direct injection engines. Although the PM emissions were measured differently across the exposure continuum, there was an overall PM emission reduction of 28% across the studies when petroleum diesel was substituted with waste cooking oil biodiesel. The overall risk of bias was determined to be ‘low’.
Conclusion: Based on the application of the Navigation guide methodology, it was found that the strength of the evidence provided was ‘sufficient’ to suggest an association between waste cooking oil biodiesel and PMemission reductions.
