The 27th Avenue Compost Facility is a state-of-the-art 55,000 ton per year composting facility – the first solid waste infrastructure project in the United States, and the first in Arizona to earn the prestigious Envision recognition. The Compost Facility is a key component of the City’s Resource Innovation Campus (RIC). Dibble performed civil engineering services for the water line extension alignment, redesign of the site utilities, grading and drainage for the site, permitting, construction administration services, Envision documentation, and team coordination.
This facility is a cornerstone to reaching the City’s waste reduction plans by 2020 and zero waste by 2050.
Additional goals for the system are diversion of 110,00 tons of waste per year (with capacity for up to 220k tpy); the process will use 100% of on-site rainwater, graywater and condensate; variable frequency drive (VFD) energy savings of 37%; LED lighting energy savings of 50%; 100% native plantings with zero percent use of pesticides or herbicides; and design of future phases to increase energy/water savings and add solar. This new, innovative system design can process compost at rates two to four times faster than most industry benchmarks.
The Composting Facility is open to the public and provides an excellent opportunity to display the entire composting process. The process takes waste material from homes and businesses and creates usable material. The processes, equipment and infrastructure displayed are a strong, visible reminder of the need for practical engineering solutions meeting everyday needs.
This project received the 2017 ACEC Engineering Excellence Grand Award for the Industrial and Manufacturing Processes and Facilities category.
