CA: School District, County Public Works Department Implement Food Scrap Composting, Food Share Programs

Here’s a recent case study of food scrap composting and a “share table” project from California:

“GOLETA, Calif. – Santa Barbara County Public Works Department and Goleta Union School District implemented a food share and food scraps composting program at nine elementary schools in Goleta on Tuesday. This program will prevent thousands of pounds of fruit, milk, containers and packaged food from heading to the landfill.”

Case Studies of K-12 Schools Fighting Food Waste—Spring 2019

Below are a few examples of food waste prevention, reduction, and diversion efforts at K-12 schools that I’ve read about recently. Check them out, and consider emulating these efforts at your school or organization!

CA: Monica Favand Campagna shared a video created to instruct parent volunteers at Franklin Elementary in Glendale, CA on proper procedures for supervising organic waste separation during breakfast, snack, or lunch. Check out the clearly marked bins for their sharing table, where uneaten, unopened foods can be placed for use by other children. According to Monica, “CA has mandates for organic waste diversion, which apply to our school district (GUSD) – and we parents at the school (I am our school’s Green Team captain via our Parent Foundation – and we also have a Green Lunch Committee under the PTA) wanted to help them initiate a program. Our hauler, Southland Disposal, provided us with green bins and picks up once per week to compost in a commercial facility about 20 minutes away. This is a pilot program for the entire GUSD – so we are really wanting this to be successful!” Good luck and continued success!

IL: LaSalle digs into onsite composting and slashes food waste: “LaSalle is one of several Chicago Public Schools (CPS) this past school year to engage students in environmental learning and action on a daily basis– right in their own lunchrooms. Since March 2019 when their zero waste program launched, LaSalle has reduced lunchroom landfill waste by over 50% by weight through food recovery, onsite composting, liquid diversion, and recycling.”

IL: Plainfield East High School students create a rap video to promote food scrap composting. What a great way to get fellow students thinking about waste management and learning how to sort! Will County, in partnership Organix and with some funds from ILCSWMA helped two Plainfield High Schools pilot food scrap collection and composting in Spring 2019 (see photo below, from Illinois Food Scrap Coalition Facebook post on the pilot program).Teenaged boy carrying empty milk carton and plate, preparing to deposit materials into waste sorting bins. Tables, other students, and other features of the school cafeteria are in background.

IL: Old School Montessori was among the organizations praised by the Village of Grayslake for their use of the village’s food scrap composting program. Learn more about Grayslake’s program on the Village web site: https://www.villageofgrayslake.com/533/Food-Scraps-Composting.

IL: Bloomington Public Schools District 87 was among the 2019 Illinois Green Ribbon Schools nominees. Composting was noted among the efforts highlighted for District 87: “The most innovative project implemented has been a district-wide cafeteria composting and recycling initiative. Since the start of the program in 2014, the district has reduced dumpster sizes by half, preventing over 50 tons of waste from entering area landfills.” Read about efforts from Green Ribbon Schools nominees from around the country in the US Green Building Council Green Ribbon Schools highlights document.

IL: Roundout Elementary School is the first in the Seven Generations Ahead-lead Zero Waste Schools-Lake County Program. “The school uses a structure called ‘the village,’ where each student takes a role in a village department. The Rondout Public Works Department took on the zero waste program as their project. Public Works students conducted the waste audits with SGA.” Excellent example of student engagement and incorporating food waste issues into the curriculum!

IN: School district turns unused cafeteria food into frozen, take-home meals for kids. “Elkhart Community Schools teamed up with a non-profit group called Cultivate to create a pilot program that will provide weekend meals for a small group of children at Woodland Elementary, WSBT reported…As part of the pilot program, 20 kids will receive a backpack with eight individual frozen meals every Friday until the end of the school year. The meals will be made using food that cafeteria workers prepared but never served, according to WSBT. ‘Over-preparing is just part of what happens,’ said Cultivate spokesperson Jim Conklin. ‘We take well-prepared food, combine it with other food and make individual frozen meals out if it.’

NC: This messy school cafeteria project dives into how students eat and waste food. Another great example of student engagement in a cafeteria waste audit! “After last week’s food audit, in which students sorted and weighed food waste, liquids, disposable trays and other types of cafeteria trash, Whitewater switched to compostable paper trays this week. Working with Every Tray Counts, a nonprofit group based in Chapel Hill, the school hopes to set the stage for a full-district switch from polystyrene to paper trays, following the lead of Chapel Hill-Carborro, Durham and, most recently, Wake County Public Schools.”

Minneapolis Public Schools Release ‘True Food, No Waste’ Action Plan

Minneapolis Public Schools (MPS) have recently released a plan to reduce costs and food waste in school cafeterias and kitchens.  As reported by JoAnne Berkenkamp and Jonathan Bloom on the Natural Resources Defense Council (NRDC) blog,

The school district today released a new “True Food, No Waste” action plan for curtailing wasted food in school cafeterias and kitchens…Developed in concert with NRDC and consultant Jonathan Bloom, the district’s plan offers an innovative model for schools around the country to follow. It also highlights an important area of opportunity for city governments as they commit to tackling wasted food in their communities.’

The plan includes a focus on ‘fresh food prepared in on-site kitchens,” and follows the EPA Food Waste Reduction hierarchy, incorporating plans for food waste prevention, diverting surplus food for human consumption, and diverting food scraps from landfill through composting.

You can read the entire NRDC blog post at https://www.nrdc.org/experts/joanne-berkenkamp/k-12-and-food-waste-reduction-innovations-heartl.

Universities Create Biodiesel from Waste Cooking Oil

A recent update from Engineers for a Sustainable World on student projects from 2018 included a note on the University of British Columbia Campus Biodiesel project. See https://www.eswglobal.org/database. According to that synopsis, “The campus biodiesel project seeks to produce biodiesel from waste cooking oil produced on UBC campus. Cooking oil can be collected from the dining halls of first year residence, in partnership with UBC food services. ESW has access to use a reactor system in the Chemical and Biological Engineering building with the capacity to produce 60 L batches. There is also a fuel dispensing system in the equipment yard of the building. The goal of the project is to produce batches of biodiesel with reliable quality to be used by diesel powered vehicles in fleet services.”

More information on the UBC campus biodiesel production project can be found on the Engineers for a Sustainable World UBC web site at http://blogs.ubc.ca/sustainabilityclub/biodiesel-project/.

This project is similar to the Illinois Biodiesel Initiative (IBI), which evolved from an Engineers Without Borders project on the campus of the University of Illinois at Urbana-Champaign. See https://icap.sustainability.illinois.edu/project/illinois-biodiesel-initiative-ibi and http://biodiesel.illinois.edu/ for further information on that project.

Similar projects have also been coordinated with high school students converting waste cooking oil from K-12 school food service operations for use in district school buses. See the archived suggested activity “Divert or create biodiesel from waste cooking oil” document from the original Green Lunchroom Challenge K-12 pledge program for more information and inspiration for incorporating such an activity, or information about it, into K-12 lesson plans.

Has your college, university, or high school/school district diverted used cooking oil to fuel in a similar fashion? Consider sharing a link to a site describing your efforts or a brief description of your project in the comments section of this post.

Growing Healthy People Brings Year-Round Gardening to IL Schools

In the 12/14/18 online edition of the Daily Herald, Paula A. Lubenow reports on Growing Healthy People, a non-profit organization which has “created year-round gardening programs at Thomas Jefferson Middle School in Waukegan, Lake Forest Country Day School and Bowen Park Urban Ag Lab in Waukegan. The organization utilizes cutting edge gardening technology including hydroponics, aquaponics and aeroponics in greenhouses to allow students to grow food year-round during the entire academic school year. The students at Jefferson Middle School also contribute their produce to the Roberti Community House and food pantries in the Waukegan area. Students learn valuable life skills through these gardening programs: how to grow their own food; the importance of healthy food and good nutrition; and about careers in horticulture.” Read the full article at https://www.dailyherald.com/submitted/20181213/growing-healthy-people-high-tech-school-gardening-programs-teach-students-important-life-skills.

There are three suggested activities related to school gardens which were part of the original Green Lunchroom Challenge voluntary pledge program for K-12 schools (out of which this blog began). Within the “Food Sourcing” category, participants in that pledge program could earn points by establishing an on-site garden to provide fresh seasonal produce on demand, expanding an existing on-site garden, or involving students in the maintenance of a school garden. Though the pledge program has ended, the suggested activity pages are still great guides to incorporating school gardens into your food waste reduction and prevention strategies in K-12 food service operations.

The practices taught through the Growing Healthy People programs would be excellent for schools interested in starting or expanding their school gardens, and they’re proven effective in student involvement. We applaud Growing Healthy People and the three schools in Waukegan, IL mentioned in the Daily Herald article for their efforts!

Coffee Grounds: Diversion to Biofuel Feedstock

Most food service operations produce some amount of spent coffee grounds. Even in K-12 schools, cafeterias, staff lounges, and administrative offices often serve coffee for the adults on site. I intend to write posts in the near future about some of the more traditional ways to divert spent coffee grounds from landfill (e.g. composting, use as a substrate for growing mushrooms, etc.). But a recent news article has prompted me to highlight a diversion strategy for this material which you may not have considered: feedstock for the production of biofuels.

You may be familiar with using spent cooking oil or grease for the creation of biodiesel. See the archived activity on diversion of waste cooking oil for biodiesel creation for more information. Coffee grounds also contain oils that can be useful in creating biofuels. As reported in the May 10, 2017 issue of Science Daily, a group of researchers from Lancaster University in the UK recently found a way to improve the efficiency of converting coffee grounds to biofuel. Their methods reduced the time required for the process, as well as the amount of chemicals used and chemical waste produced. According to the article: ‘”Our method vastly reduces the time and cost needed to extract the oils for biofuel making spent coffee grounds a much more commercially competitive source of fuel,” said Dr Najdanovic-Visak, Lecturer in Lancaster University’s Engineering Department. “A huge amount of spent coffee grounds, which are currently just being dumped in landfill, could now be used to bring significant environmental benefits over diesel from fossil fuel sources.” The process has the potential to enable 720,000 tonnes of biodiesel to be produced each year from spent coffee grounds.’

On October 2, 2018, Ohio-based Dunkin’ Donuts Coffee at Home introduced a “tiny home” in New York City’s Madison Square Park which is powered by biofuel created from spent coffee grounds. The biofeul is a custom B80 blend created by Blue Marble Biomaterials–80% of the fuel is oil from Dunkin’ coffee grounds and 20% is alcohol to allow the fuel to burn efficiently. The “Home that Runs on Dunkin'” will be open to the public in Madison Square Park in New York City, on Broadway between 23rd and 24th Streets from Thursday, October 4 through Saturday, October 6.  If you’re curious but not in NYC, check out the 360 video tour available at https://www.dunkinathome.com/whats-new/home-runs-on-dunkin. According to that site, “Every 170 pounds of spent coffee grounds yields about one gallon of fuel and is used in a standard biofuel generator.” The site also states that 65,000 pounds of spent Dunkin’ coffee grounds were used to create the biofuel.

Of course, this particular solution isn’t practical for small generators such as a single school, restaurant, or hospital. But restaurant and hotel chains or large institutions, particularly those in areas where on-site composting is infeasible and where commercial composting service is not available, might be interested in exploring the possibility of partnering with a biofuel producer to divert coffee grounds from landfill. To assist in such investigations, see the National Biodiesel Board’s map of member plants at http://biodiesel.org/production/plants/plant-maps#map. You could also reach out to colleges and universities in your area to see if scientists on campus are conducting biofuel research and might be interested in using your spent grounds as feedstock in their experiments.

SCARCE Webinar 9/18/18 on Sharing Tables

Join SCARCE (School and Community Assistance for Recycling and Composting Education) on September 18 from 1:00 – 2:30 PM CDT for a free webinar on how to start a sharing table at your school.

A sharing table is a system in which uneaten unopened packaged foods or beverages, or unpeeled fruits, may be placed in a central location within a lunchroom by student that do not want them, so that other children may consume these items. This diverts edible material from the waste stream to human consumption. See the related suggested activity from the original Green Lunchroom Challenge program for further information on establishing a sharing table.

In their upcoming webinar, SCARCE will discuss the what, why, and how of starting a sharing table in your cafeteria with real-world examples drawn from their experience working with schools.

Register for the webinar at https://www.scarce.org/event/how-to-sharing-table918/.
