Circular Solutions Advisors performs on-site audits. One of the audit services is an environmental impact report for bottled water. The audit focuses on two types of bottled water packaging; Polyethylene terephthalate (PET) and  Aluminum (ALU). Companies that manufacture ALU and PET packaging for bottled water have historically provided data that creates biases to their form of packaging. This creates a conflict regarding the information available about both PET and ALU packaging for bottled water.

Circular Solutions Advisors (CSA) can conduct an audit and provide a report based on credible neutral sources. The basis for our audit and reporting methodology is derived from the following sources.
