Results include energy savings of more than 970,000 kWh and over $125,000 in energy costs as well as improved color rendering, lighting consistency, and brightness.
CSU Northridge, Integrating waste diversion and organic gardening into a learning opportunity
A coordinated effort between the Institute for Sustainability and CSUN dining services resulted in diverting all pre-consumer waste from campus dining areas and coffee shops to go to composting and organic gardening. Closing the loop between these previously independent activities provides cost savings to the university, advances a zero-waste agenda, and fosters a culture of sustainability among the University community. The program provides a facility where the community can learn principles of sustainability and engage in practical efforts to implement changes. It also provides work experience for students employed by the Institute to run the compost and food garden operations.
UC Santa Barbara, Optimizing Waste Management Services Through Stakeholder Engagement
A pilot custodial staff engagement program developed by UCSB improved waste management practices and decreased the workload required from custodial staff to service the indoor waste infrastructure. Facilities managers walked 10 buildings on campus with custodial staff to identify underutilized and outdated containers as well as locations where new containers and signage were needed. Waste collection practices were improved through a collaborative approach to understanding the needs of custodial staff, resulting in reduced contamination of recyclables, use of fewer bin liners, and less time required to service receptacles. The program also fostered feedback amongst custodial staff and management.
Honorable Mention: UC Davis, Gravel Washing/Recycling System
The gravel that lines the pens at the California National Primate Research Center at UC Davis used to be thrown out after use, accounting for roughly 25% of campus waste. While many options had been studied through the years, it took a new employee’s innovative concept of using recycled water from the wastewater treatment plant, a cement mixer, and gold mining equipment to effectively clean the gravel for reuse. This single project has increased the campus diversion rate from 66% to 76% and the net costs to run the system, including the amortized system cost, are lower than landfill disposal.
Sustainable Food Service
San Diego State University, Dining Certified Green Restaurant® Excellence
SDSU Dining has systematically implemented sustainable operational practices across each of its 33 foodservice locations to earn Green Restaurant certification on individual restaurants, catering, residential dining, centralized production, concessions, the Faculty/Staff Club, and even convenience stores.
