- Achieve zero waste (defined as 90 percent diversion from landfill) by 2020 at all locations other than UC Health locations, which will have separate waste reduction goals.
- The University will reduce per capita total municipal solid waste generation at all
locations other than health locations as follows:
a. Reduce waste generation per capita to FY2015/16 levels by 2020
b. Reduce waste generation by 25% per capita from FY2015/16 levels by 2025
c. Reduce waste generation by 50% per capita from FY2015/16 levels by 2030
- By 2020, the University will prohibit the sale, procurement, or distribution of Expanded Polystyrene (EPS) other than that utilized for laboratory supply or medical packaging products.
Progress Towards Goals
Collectively, UC campuses and medical centers diverted 58 percent of municipal solid waste from landfills in 2015-16. Including construction and demolition (C&D) waste, the
total diversion rate was 69 percent. However, excluding medical centers, the systemwide diversion rate was 76 percent this year, up 4 percent from last year. UC Irvine continues to achieve the highest waste diversion rate at 80 percent (not including C&D). UC Riverside (78 percent), UC San Francisco (74 percent), UC Davis (72 percent) and UC Santa Barbara (68 percent) are not far behind.
Waste diversion rates have plateaued on many campuses in recent years, with only UC Riverside and UC San Francisco achieving significant increases in diversion rates since
2014-15. There are several potential explanations for the lack of further progress toward the zero waste goal. The primary barriers to achieving zero waste include the challenges of capturing the compostable waste stream, convincing suppliers to provide reusable or recyclable packaging, the changing market for recyclable materials and the limited number and proximity of composting facilities.
However, flattened diversion rates are also partly due to the success of programs emphasizing the principles of “reduce and reuse,” such as reusable water bottle campaigns. For example, reuse means that there is a reduction in total waste; however, some of that avoided waste was recyclable material like plastic water bottles. Diversion rates therefore do not fully capture efforts to reduce or reuse waste. In order to track the success of waste reduction efforts, campuses also report waste generation per capita as a complementary metric to the diversion rate. The Merced, Riverside, San Diego and Santa Cruz campuses reported the lowest pounds of waste per weighted campus user.
