FARMS Leadership | San Joaquin | January 21, 2022
Location of Field Day: Cal-Waste Recovery Systems – Galt, CA
Field Day Host and Mentors: Cal-Waste Recovery Systems – Leesa Klotz
Theme: Recovery Recycling, Climate Change & Healthier Communities
Our friends at Cal-Waste Recovery Systems were the ideal hosts for our first FARMS field day of the new year. We spent the day observing exactly what happens to our recycling once the truck whisks it away– and everything we saw generated lots of conversation around landfills, climate change, reducing all kinds of waste, and spreading community awareness.
As usual, we kicked off our field day with our opening circle check-in and a student leadership activity. Our leadership activity was a lively one: students lined up along a rope, each holding it with one hand. After taking note of the order of their peers, they were instructed to close their eyes (and keep them closed!) and communicate verbally to form various shapes and letters. We started out simple: a square. After our first shape, students took some time to brainstorm what worked, what didn’t, and their strategy for the next shape. Through use of their communication, listening, and creative thinking skills as well as their abilities to establish trust and remain open to all ideas, the group successfully shaped a square, a triangle, and the letter T.
Next we were joined by Cal-Waste’s Education Coordinator Leesa Klotz. After Leesa gave us an interesting and stinky history of garbage, we all suited up in our PPE and headed out to the MRF: the Material Recovery Floor. This is where all the recyclable materials picked up from Cal-Waste’s trucks are dumped, processed, sorted, and bailed. This is also where any pesky residual trash that makes its way into the recycling bin is separated to be sent to a landfill. Cal-Waste is committed to recovering every valuable resource from the waste stream to prevent as many items from being forever landfilled as possible.
The MRF was epic to say the least. A marvel of technology intricately designed and pieced together–conveyor belts, drum feeders, augers, magnets, crushers, air expansion chambers, optical sorting machines, infrared technology, and plenty of quality control personnel along the way to ensure accuracy and safety. Students were particularly enthralled with the bailer: a machine that crushes hundreds of tons of sorted recycling into massive cubes of cans, plastic bottles, cardboard boxes, etc. These cubes are then sold to facilities that will transform the recycled material into new products.
After lunch, we returned to Cal-Waste’s state of the art education center for some conversations on reducing waste and food waste recycling. Students learned California has passed a new food waste law, requiring all Californians to separate their organics from the rest of their trash. Leesa informed us of some shocking food waste stats:
- A third of all the food produced in the US goes to waste.
- Food takes up more space in landfills than anything else.
- The US wastes more food than any other country in the world.
- Before the pandemic, 35 million Americans experienced food insecurity. After/during the pandemic throughout 2022, that number is expected to rise to 50 million Americans.
All this sparked some conversation: what can the students do to make a difference in their own school? Students brainstormed ideas about hosting focus groups between students and administrators, making informational posters, providing student waste ambassadors who can guide students on disposing of waste correctly, and re-working cafeteria food distribution requirements so less food goes to waste.
We finished the day out with a waste sorting activity: Leesa dumped two bags of trash/recycling on the table and asked two teams of students to sort them from the waste that would take the least amount of time to the most amount of time to decompose in a landfill. Students were shocked to learn that a paper towel can take a month to decompose all the way down to a glass bottle that can take 1,000 years (or might never decompose!).
During our closing circle, students shouted out their highlights: feeling inspired to reduce their food waste, exploring the MRF, learning about all the unexpected jobs within a recycling facility, and the morning’s leadership activity. Thanks to our partners, supporting teachers, and of course the students for making it a memorable day as always!
