A Less-Waste Plan for the Civic Hall Kitchen

Lunch at Juniper Civic Hall

Juniper Civic Hall serves community lunches. Its kitchen committee wanted to learn whether changes at the serving counter could reduce food left on plates. A county resource guide explained that growing and preparing food uses water, land, and energy. The guide also described composting: tiny living things break down food scraps into material that can be added to soil. Composting happens after scraps exist; the committee also wanted to investigate changes made before visitors finished eating.

Kitchen staff compared four five-day lunch trials. Each trial served 100 lunches per day and used the same menu of bean soup, rice, cooked vegetables, and fruit. Staff used the same scale and weighing method. They collected and weighed uneaten food from plates separately from preparation scraps, such as fruit peels. Packaging was not included in either food measurement. The graph shows the total uneaten food collected during each trial.

The baseline trial used the kitchen's usual servings and no new signs. In the smaller-servings trial, staff offered smaller first helpings, but visitors could return for more. In the signs trial, signs reminded visitors to choose amounts they expected to eat. The combined trial used both changes. One-time supply costs were $30 for smaller servings, $20 for signs, and $50 for both changes together.

The committee also checked the local compost program's guide. This program accepts all the food scraps from the kitchen's menu, including plate leftovers and preparation scraps. It does not accept the kitchen's wrappers. The guide tells users to keep wrappers out of compost collections.

During a later five-day compost pilot, the kitchen used both serving changes again. Staff measured 16 kilograms of uneaten food and 20 kilograms of preparation scraps. Of these 36 kilograms, 24 went to the compost program and 12 went into landfill trash. Staff removed misplaced wrappers before weighing and sending the compost collection. Volunteers noted that the compost bin and trash bin stood far apart, and several visitors could not tell which bin to use. For comparison, the baseline week had sent 60 kilograms of food scraps to landfill trash: 40 kilograms of uneaten food and 20 kilograms of preparation scraps.
