One of the first things you notice at Crossroads Dining Hall is that there are no trash cans. If you don’t eat what’s on your plate, you recycle it.
UC Berkeley is doing such a good job of recycling that today (Thursday, Nov. 15), America Recycles Day, the regional administrator of the Environmental Protection Agency came to campus to praise Cal Dining’s efforts to reduce the food waste stream — in particular, by cutting upstream food purchases to limit downstream waste.
At a morning press conference outside Crossroads, Jared Blumenfeld, who oversees the EPA’s Pacific Southwest region, which includes the West Coast and Hawaii, announced that UC Berkeley is one of 19 colleges and universities in the region to sign up for the Food Recovery Challenge. The voluntary program aims to limit wasted excess food nationwide through donations to charity, reducing consumption and increasing composting
“Americans waste 40 percent of the food we buy – 34 million tons annually,” Blumenfeld said. “In Berkeley as a city and a campus, a lot is going on in the area of recycling, and the EPA is proud to partner with UC Berkeley and the 18 other universities as they commit to support the environment and their community by reducing food waste.”
Shawn LaPean, executive director of Cal Dining, said that employees recycle as much uneaten food as possible: leftovers are often picked up by student groups to take to homeless shelters, while trimmings, scraps and post-consumer waste are diverted to composting. Since August 2011, Cal Dining staff have also weighed and tracked wasted food via computer software called LeanPath. Thanks to the software and staff incentives, Cal Dining has reduced kitchen waste by over a third – from more than 3,000 pounds a week to about 2,000 –resulting in avoided food purchases of more than $1,600 each week. Cal Dining’s goal for 2013-14 is to have food cost savings of approximately $700,000.
“Staff are now constantly sharing with me different ways to save on food waste,” LaPean said. “There used to be a culture of ‘it’s just waste.’ Now there is ownership and buy-in in the process of improving.”
“UC Berkeley is using one of the best approaches to eliminating food waste — preventing it from entering the waste stream in the first place,” Blumenfeld said. “The university’s innovative food waste tracking system helps match food purchases with demand, ensuring that as little food as possible goes to waste every day. UC Berkeley has also made big strides toward its zero waste goals through an extensive composting program that raises the bar for other universities nationwide.”
So it’s no surprise that Cal Dining was one of the first to sign up this year when the EPA initiated its Food Recovery Challenge. To date, nearly 60 colleges and universities nationwide – including eight UC campuses – have pledged to reduce their food waste by 5 percent in one year.
“If each of these colleges representing 460,000 students saves 5 percent of food waste going to landfills, that amounts to about 3 million pounds of food,” Blumenfeld said.
UC Berkeley’s food waste reduction and recycling program is part of a campuswide effort to make UC Berkeley sustainable and to lower its carbon footprint in the face of global climate change.
“I can’t talk about sustainability on campus without talking about student engagement and involvement. We have over 30 student groups and service learning programs, like Building Sustainability@Cal and Cal Dining’s Sustainability Team,” said Lisa McNeilly, the campus’s director of sustainability. “Our students motivate our work, participate in implementation of projects, and graduate to become leaders in the sustainability field.”
Say no to landfill
In the Crossroads Dining Hall, students deposit their trays ‑ uneaten food, utensils, napkins and all – for staff to sort into separate piles: compostable, reusable or recyclable. Dishes are washed, but the compostables are squeezed dry and sent to a local composting firm in Richmond, saving energy and greenhouse gas emissions formerly required to truck the waste to the Central Valley, said campus recycling coordinator Lin King.
“We deal with the tail end of the waste stream,” said King, who signed the campus up for the Food Recovery Challenge. “Our goal is that all the waste become something else, and especially, that the food waste become compost for farmers to grow more food.”
By promoting reusable, recyclable or compostable cups, utensils and trays, plus the newest initiative – giving students a choice between reusable and compostable take-out boxes – Cal Dining plans to reduce landfill waste to zero by the year 2020.
In the campus’s 2012 sustainability report, McNeilly reports the following accomplishments during the past year:
- Greenhouse gas emissions have dropped by 3.7% relative to 2010, primarily because our utility provided additional low-carbon power. While total GHG emissions have risen 11.7% since 1990, emissions per research dollar have dropped by 31.5% in that same time period.
- Water use dropped 3.6% last year and is down 8.2% since 2008 – close to our 2020 reduction goal of 10%. Campus sales of water bottles have declined by 48% since 2006.
- The campus has 10 LEED™ certified building projects, representing almost 7% of total square footage.
- The waste diversion rate for campus (when construction waste is excluded) has increased by 5 percentage points to 46%, while the amount of solid waste sent to landfills by the campus went down by 4.4% last year.
- Fuel use from fleet and commute continues to be at least 25% below 1990 levels, exceeding the campus goal. The percentage of green vehicles in the fleet has risen to almost 22%.
- Campus purchases of sustainable foodremain higher than the 20% goal set for 2020.
