A brief description of programs, policies, infrastructure investments, outreach efforts, and/or other factors that contributed to the diversion rate for construction and demolition waste:

UC Irvine had a diversion rate of 83.28% for construction and demolition (C&D) waste for the performance year. This includes waste generated by small construction & renovation projects and waste from major capital improvement building projects.

On small construction and renovation projects, UCI actively collects all C&D materials generated using 20 cubic yard lowboy containers and 40 cubic yard bins at the job site. A system of source separation is used for concrete, asphalt and metals. For mixed construction debris all material is taken to a transfer station with a C&D material recovery facility (MRF) that provides an average diversion rate of 70-75% for C&D material.

In addition, campus renovation and maintenance projects are provided use of 40-yard metal collection bins for the recycling of all metal from renovation and plumbing jobs to ensure that all C&D jobs have free and easy access to source separation and collection of this material. For the collection and recycling of all other C&D jobs on campus, UC Irvine works in partnership with a local vendor that provides C&D MRF services to on-campus contractors at a low cost and a guaranteed a diversion rate of 70% or higher, ensuring that all contractors working on campus have a cost-effective means of recycling construction waste at these high diversion rates.

All major capital improvement construction projects on campus divert a minimum of 75% of construction and demolition waste as part of UC Irvine’s campus wide green building program. UCI projects are required to meet a minimum level of LEED Silver certification and compliance includes a LEED Credit requirement to divert a minimum of 75% of construction and demolition waste. LEED accredited construction staff monitor C&D waste generation and recovery and maintain documentation to confirm waste diversion compliance.

UCI uses Hot In-Place Asphalt replacement program instead of the traditional asphalt removal and replacement (https://www.youtube.com/watch?v=mf88DU3omfg). With specialized equipment we are able to use the existing asphalt by melting the damaged asphalt and resurfacing the road. This eliminates trucking of used asphalt and recycles the asphalt to be used in the new road surface replacement.
