Conference Speakers

Todd Blair

Todd Blair started his solid waste management career in 1989 where he gained experience of how waste feedstocks are collected from the community in preparation for proper diversion and disposal. From there his passion for sustainable practices continued to grow as a manager of multiple recycling processing plants and as an independent commodities trader. His career has provided him the full circle understanding of how waste material is collected, processed and then sold to end markets for remanufacturing. His expertise in this realm was furthered in his role for Phoenix Aviation where he led various initiatives that resulted in exceeding the established waste diversion goals by nearly 10%.  Todd is currently on the board of directors for the Arizona Recycling Coalition which gives him opportunity to share the importance of waste reduction, reuse and recycling/composting. Todd seeks to create a sustainable future for Arizona by connecting with the community to find ways to advance circular economy and sustainable solutions to the growing waste issue.   In his off duty time, Todd provides volunteer counseling for MSCO inmates.
