Mill Food Recycler Educators Guide

The Mill Food Recycler Educators Guide, developed by Arizona State University’s Sustainability Teachers Academy in collaboration with WWF, Incite, and Mill, offers a curriculum for K-12 students to manage food scraps and understand food systems. The guide includes specific lesson plans ranging from preschool to 12th grade, covering subjects such as science, math, reading comprehension, and visual arts. These lessons use the Mill Food Recycler to demonstrate the transformation of food waste into 'Food Grounds,' exploring concepts like carbon cycling, chemical and physical changes, and the impact of landfills. Additionally, the document provides strategies for school-wide food waste reduction, such as 'Share Tables' and 'Offer vs. Serve' policies, and highlights the success of the Food Waste Futures Fellowship Program in the Phoenix metropolitan area.

• The guide was developed through the Food Waste Futures Fellowship Program, which supported 10 K–12 educators from five Title I schools in the Phoenix metropolitan area to integrate food systems sustainability into their classrooms.
• The Mill Food Recycler is used as a tool to demonstrate how food waste is transformed into 'Food Grounds,' which can be utilized in gardens, compost, or as an ingredient for chicken feed.
• Science lessons for 2nd grade use the Mill to teach the difference between physical and chemical changes, specifically demonstrating how heat causes water to evaporate and reduces the mass of food waste.
• For 5th grade Earth Science, the guide suggests using Mill Food Grounds to feed worms in vermicomposting bins to teach students about the soil-food web and decomposers.
• High school integrated science lessons use the Mill Food Recycler to investigate carbon cycling, specifically measuring CO2 production in soil treated with Food Grounds compared to a control sample.
• The guide proposes a classroom management system with specific student roles to maintain food recycling routines, including 'Food Waste Warriors' for collection, 'Mill Monitors' for machine operation, and 'Compost Champions' for weighing recycled waste.
• The document highlights food waste reduction strategies implemented in the Tempe Elementary School District, such as conducting student 'taste tests' for menu items to ensure they are eaten and reducing food expenditures.
• The guide recommends two specific cafeteria-level strategies to minimize waste: 'Offer vs. Serve,' allowing students to decline meal components they will not eat, and 'Share Tables' for distributing unopened, unused food.
