Stanford has one of the longest running university waste diversion programs in the country, with roots going back to the 70s. Stanford’s long history of minimizing waste began with a student-led recycling program, and student involvement remains an essential component of the university’s sustainability programming. The total amount of material that Stanford sends to the landfill has significantly declined due to robust efforts to minimize campus waste, including increasing recycling and composting.
These efforts are critical as the university works toward becoming a zero-waste campus, defined as a 90% diversion rate or higher, by 2030. Stanford's diversion rate in 2018 was 64%, which is a 34% increase from 1994. Learn more about ongoing initiatives.
Stanford initiated a Zero Waste Plan and Feasibility Study in 2017 to develop a comprehensive analysis of waste infrastructure, practices, and programs on campus to-date. The study was conducted using internal resources and peer reviewed by industry experts.
The Zero Waste Plan and Feasibility Study prioritizes reduction, spearheaded by initiatives in purchasing and contracts, followed by reuse, recycling, and compost, as indicated by the waste hierarchy. Education and community outreach will help to facilitate progress through every step of the way, to embed responsible resource management and waste minimization behaviors into the campus culture.
What solutions did the study identify that will help Stanford improve its diversion rate from 64% to 90% or higher? Extensive waste audits reveal that more than 75% of what ends up in the landfill could be recycled or composted. The solutions in the Zero Waste Plan and Feasibility Study focus on stronger green purchasing policies and increased reuse and composting across Stanford's schools, departments, and buildings, along with enhancing the existing recycling program. The Zero Waste Plan and Feasibility Study will also be peer reviewed by the Sustainability Design Team faculty identified as a part of Stanford's Long Range Plan.
The cross-cutting benefits of a comprehensive waste management program include conserving energy, reducing landfilled materials, conserving natural resources by providing recyclable materials to manufacturers, and cutting greenhouse gas emissions and other pollution from the supply chain.

- The Deskside Paper Recycling and Mini–Trash Can Program expanded to 106 buildings, with 8900 total bin sets and Zero Waste Guidelines delivered. This program is becoming the campus standards as it continues to be extended into existing and new academic buildings.
- Departments have funded 122 compost collection points through the Customer-Funded Compostables Collection Program, launched in July 2015. The Voluntary Compost Program increased participation to over 361 volunteers collecting food and other compostable materials from common spaces to bring to collection bins.
- Over 450 people were trained on best waste sorting, recycling, and composting practices through waste reduction classes, café staff trainings, and tours of the Stanford Recycling Center.
- Stanford Surplus Sales’ furniture reutilization program helps departments avoid landfill fees and contributes to university sustainability goals by collecting and selling unwanted furniture and equipment at discounted prices. The program successfully diverted approximately 327 tons of furniture from landfill in 2018-19, including 185 tons of furniture from buildings that were vacated in preparation for the new Stanford Redwood City campus.
- Stanford Surplus Sales collected and processed 118 tons of electronic waste in 2018, and ensured the material was appropriately recycled.
- Three Sustainability Game Day Challenges were hosted in partnership with the Department of Athletics, Physical Education, and Recreation. Game Days resulted in an 8-24% increase in waste diversion rates from the prior year, thanks to increased composting infrastructure, food donation programs, student participation, and fan outreach and engagement. These efforts also resulted in a nearly 9% overall increase in waste diversion at the stadium, including an almost 12% increase in the tailgating areas.
