Application of Quantitative and Qualitative Methods for Building a Case for Industrial Pollution Prevention: Case Study of a Dairy Processing Facility

This thesis investigates the use of a combined set of quantitative and qualitative tools to help address known barriers associated with adopting and sustaining pollution prevention (P2) in an industrial manufacturing setting. The research was conducted at an Ontario dairy processing facility in the form of a case study. P2 is an alternative approach to traditional pollution control or abatement techniques. P2 is a preferred method for pollution management, both environmentally and economically, as it focuses on the efficient use of resources to prevent pollution at the source. The tools used in this research included: wastewater treatability testing, hierarchical process mapping, employee interviews, and causal loop diagrams (CLDs). The application of these tools assisted the participating facility in better characterizing its existing environmental problems, uncovering concrete resource saving opportunities within its processes, and providing more adaptive visual approaches of documenting and conveying P2 concepts.
