Description
Infrastructure degradation is a chronic problem for fats, oils, and grease (FOG) pretreatment programs at wastewater utilities, which can lead to harmful bypass and high loss of a renewable energy feedstock. Not only does this exacerbate the potential for environmental harm, but not taking advantage of this resource leaves most FOG anaerobic digestion programs non-resilient and non-scalable. It is vital that there are strategies utilizing a sustainability perspective and integration of hard and soft infrastructure management principles to address this infrastructure degradation issue before there can be fully implemented zero-waste, FOG resource recovery initiatives. This applied project sought to answer the question, “How can municipalities sustainability manage the issue of degrading FOG pretreatment infrastructure?” with an emphasis on providing an applied example where a sustainability approach can mitigate complex, infrastructure problems. In partnership with the City of Tempe’s Environmental Services Section, this project addressed the issue of degrading infrastructure by crafting and implementing a comprehensive Infrastructure Assistance Program (IAP). Designed to assist food service establishments (FSEs) and wastewater utilities, the IAP provides pathways for preventing FOG infrastructure degradation through initiatives that bolster hard and soft infrastructure to support a more efficient means of achieving compliance and local goals for resource recovery and renewable energy.

Description
The Carbon Reduction Transportation Initiative (CRTI) at Northern Arizona University (NAU) was created to improve both recruitment and retention
efforts while significantly lowering NAU’s carbon footprint. Through a collective subsidization between NAU and the City of Flagstaff, the CRTI would
be able to provide all NAU students and staff free access to public transportation. This initiative would also help to reduce the amount of traffic
congestion in Flagstaff’s downtown business district and free up valuable parking spaces both on and off campus. In addition, Flagstaff’s public bus
system, the Northern Arizona Intergovernmental Public Transportation Authority (NAIPTA) would become eligible to apply for larger grants with the
anticipated increase in ridership. This would then allow NAIPTA to increase both the number and the frequency of bus stops which would benefit the
entire Flagstaff community.
