Non Technical Summary
We propose to conduct and evaluate a consumer pilot campaign that supports the development and refinement of educational messages and materials that meaningfully reduce the amount of wasted food created in U.S. households. We will work with three U.S. cities to implement and evaluate a pilot household food waste reduction campaign that builds from materials that are likely to be used in future national consumer food waste education campaigns.The major goals of this proposal are to (1) identify and refine educational messages and materials appropriate for a household food waste reduction campaign that can meaningfully reduce the amount of wasted food created among U.S. households; (2) conduct and assess pilot household food waste reduction campaigns in three cities in the United States, (3) anticipate challenges a national household food waste reduction campaign would encounter during a national roll out, and (4) project the food waste reduction potential and cost-benefit ratio of different national strategies for a household food waste reduction campaign.The evaluation will use two complementary measurement approaches - route-level waste audits and household level suveys - to ensure a robust and valid evaluation of campaign effects. Measurement will occur in both treatment and a carefully selected control group within each city to ensure valid estimation of campaign effects on household food waste generation. The results of the evaluation will inform projections of food waste reductions from different nationwide campaign roll out strategies and cost-benefit analyses of different national campaign roll out strategies. These efforts will also identify likely roll out challenges that may face any regional or national campaigns and provide recommendations for additional testing that could be crucial to ensure success of future large-scale campaigns.

Goals / Objectives
The major goals of this proposal are to:Identify and refine educational messages and materials appropriate for a household food waste reduction campaign that can meaningfully reduce the amount of wasted food created among U.S. households.Conduct and assess pilot household food waste reduction campaigns in three cities in the United States.Anticipate challenges a national household food waste reduction campaign would encounter during a national roll out.Project the food waste reduction potential and cost-benefit ratio of different national strategies for a household food waste reduction campaign.
Project Methods
We propose the following:Task 1. Campaign Formulation. We will engage with experts from government, non-governmental organizations, and the private sector familiar with consumer food waste reduction campaigns. If materials have been identified by federal agencies for use in future national campaigns, the pilot campaigns will focus on fine tuning these materials. If such materials have not been identified, then we will discuss the relative merits of adopting existing campaigns (e.g., Oregon's 'Don't Let Good Food Go Bad!', Ohio's 'Save More Than Food') for use in the pilot with selection based on: evidence of campaign efficacy; the adaptability of the campaign to pilot cities; inclusiveness and accessibility of campaign materials; and expert assessment of potential impact. The exact materials to be shared and the communications channels will be determined in cooperation with officials from the selected pilot cities to ensure local suitability and to improve efficacy.Task 2. Pilot City Selection. We will develop a geographically dispersed list of possible pilot cities to ensure that the campaign reaches areas with substantial populations enrolled in USDA FNS programs. We will work with USDA and US EPA to select communities based on characteristics such as climactic conditions, socioeconomic profile, food system infrastructure, composting prevalence, past exposure to campaigns, among others. We will approach city officials to seek cooperation in conducting a pilot. Funds are budgeted to offset cities' personnel time spent supporting the pilot.Task 3. Baseline Assessment. The assessment unit is the municipal waste hauler's residential collection route. 84 residential waste collection routes suitable for randomization (half treatment, half control) will be identified in each city, permitting attrition of ~5% while still meeting the target of 80 routes to ensure the power needed to identify a 20% food waste reduction effect of a campaign.We assume routes have 500 residences, implying data collection representing ~42,000 residences per city. A contractor intercepts garbage trucks after route completion, collects a randomly selected sample of waste (~200 pounds), transports it to a designated sorting location, and sorts it into 10 comprehensive, mutually-exclusive categories: produce, pasta/bread/rice/cereal/beans, meat and fish, soups/sauces, potato, snacks, dairy and eggs, beverages, inedible (i.e., food never intended for consumption, like bones, pits and peels), and all other (non-food and non-beverage) items. The fraction of the sample by weight as assessed by electronic scale in each category provides baseline measurement.Because this form of assessment does not assess the absolute level of food waste generated on a per household basis does not measure wasted food that is fed to animals, discarded down the drain or composting, we will also recruit households from each route to complete surveys. We will use the OSU/RECIPES National Household Food Waste Tracking Survey along with correction factors being generated by Roe's FFAR/USDA-OCE project to generate estimates of the level of food wasted by route households. We recognize these data will be affected by self-selection bias and plan to use post-hoc econometric methods to adjust for such biases.This survey will be customized to permit assessment of household member awareness of food waste topics and reduction approaches prior to the circulation of the campaign materials. Depending on the city and its communications infrastructure, recruitment will occur via mailers to addresses on the selected routes or via emails and texts to household contacts on the control and treatment routes. In either case, the communications will invite participants to connect with a link to complete the survey and highlight participation incentives. Use of the Tracking Survey will also permit us to compare the level of self-reported waste in pilot cities against contemporaneous self-reported household food waste as captured by ongoing OSU/RECIPES National Household Food Waste Tracking survey, which uses the same instrument. This will permit assessment of whether the waste amounts and patterns among households in participating cities are distinct from a comparable sample drawn from elsewhere in the United States.Task 4. Campaign Implementation. We will create 42 route pairs from each city's 84 routes where each pair features similar characteristics as determined through the use of Census data and expert opinion of city personnel. One route in each pair is randomly assigned to treatment. Treatment residences receive campaign materials via mailings delivered via the U.S. postal service and, where possible, via email or text message. Delivery of campaign materials via mass media will be avoided to ensure integrity of the control group. Task 5. Follow Up Assessment.Follow up assessments will mirror the baseline measurements and be repeated twice: 1-2 months and 6-8 months post campaign. Questions will be added to the survey to assess residents' awareness of and favorability towards campaign materials. City officials will be canvased for feedback concerning campaign roll out and impacts.Task 6. Analysis. A difference in differenceanalysis will be conducted in which the differences between the pre- and post-intervention measures across the treatment routes will be contrasted to the pre/post differences among the control routes. An example regression equation would be:Yi= b0+ b1*Treatmenti+ b2*Posti+ b3*Treatmenti*Posti+ b4*Xi+ ei,where Yiis an outcome variable for uniti(e.g., fraction of routei's sample that is wasted food), Treatmenti equals one if unitiwas in the treatment group (e.g., got campaign materials) and zero otherwise, Postiequals one if the observation occurred after the campaign initiated and zero otherwise, Xidenotes other characteristics of the unit (e.g., route-level income and housing type), and eirepresents the remaining factors that influence the outcome but are not measured. Regression analysis yields estimates of coefficients (b0- b4) with b3the coefficient that indicates the average effect of the treatment on the treated.Outcome variables to be assessed include all-category wasted food (as a fraction of the total solid waste sample), food scraps (inedible food waste as a fraction of the total solid waste sample), wasted food by category (each category as a fraction of the total solid waste sample), surveyed food waste amounts (in levels for total wasted food and waste by food category), awareness of food waste as a topic, awareness of the specific food waste reduction campaign, and self-assessed food waste reduction effort.Analyses within particular groups (city, socio-economic strata, dominant housing form) will be conducted. The estimates will help predict reductions in food waste associated with different national campaign roll out strategies. Projections will be based upon any heterogeneity identified among the pilot cities using differences in demographics across regions as documented by Census. The approach provides total reduction in food waste possible from implementing campaigns across the entire United States. Optimization exercises will identify the greatest reduction in food waste for different levels of national campaign funding and the cost-benefit ratio achievable for different funding levels. The optimization approach will be sufficiently flexible to permit restrictions, e.g., minimum proportions of total campaign funds expended in different geographic regions or to prioritize waste reduction among targeted demographic segments.

Outputs
Target Audience:The target audiences of this grant include (1) policy makers, leaders and staff in governmental and nongovernmental agencies at the local, state and federal levels and (2) select residents of three partner cities in the United States. By the end of this reporting period we had reached key leaders and staff in three U.S. partner cities concerning two key objectives: (1) identify and refine educational messages and materials appropriate for a household food waste reduction campaign that can meaningfully reduce the amount of wasted food created among U.S. households and (2) conduct and assess pilot household food waste reduction campaigns in three cities in the United States. With respect to objective (5), which involves developing an integrated Extension education program based upon current best practices, we were able to connect with 704 personnel in city, regional and state governments and non-governmental organizations across the United States as part of an inaugural webinar program with 44 people becoming formal members of the Consumer Food Waste Community of Practice website group. Among webinar attendees, the most frequently mentioned areas of food waste interest included consumers (21%), cooperative extension/higher education (21%), schools (12%), municipalities (11%), non-profits (9%), food retail and foodservice (7%), farm and production level (5%) and other (13%). With respect to target audience (2), we were able to reach more than 18,000 residents in one of our partner cities (Columbus, Ohio) with physically mailed messages intended to increase awareness of food waste as a source of household expenses and to encourage practices to save money by reducing food waste generation at the household level. We also delivered these messages electronically to a subset of more than 2,700 of these residents who opted in to receiving electronic messages from the City of Columbus and via door-to-door canvasing efforts for a smaller subset of these residents. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?One graduate student received training on conducting household surveys and statistical evaluation techniques associated with a randomized controlled trial. How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?Goal 1: Identify and refine educational messages and materials appropriate for a household food waste reduction campaign that can meaningfully reduce the amount of wasted food created among U.S. households. Under goal 1 during the upcoming reporting period, we will work with officials from the second and third partner cities of Denver, Colorado and Tampa Bay, Florida, to identify and refine educational messages and materials appropriate for a household food waste reduction campaign in their cities. Goal 2: Conduct and assess pilot household food waste reduction campaigns in three cities in the United States. Under goal 2 during the upcoming reporting period, we will complete the process of assessing the household food waste reduction campaign with our first partner city of Columbus, Ohio, by completing data collection and analyzing the resulting data. Planning will continue for similar efforts with the other two partner cities of Denver, Colorado and Tampa Bay, Florida. Goal 3. Anticipate challenges a national household food waste reduction campaign would encounter during a national roll out. Goal 4. Project the food waste reduction potential and cost-benefit ratio of different national strategies for a household food waste reduction campaign. For Goals 3 and 4, during the upcoming reporting period, we will begin to develop a framework for undertraining these tasks. Goal 5. Develop an integrated Extension education program based upon current best practices and refined based upon the campaign pilot study findings to prepare personnel in city, regional and state governments and non-governmental organizations to implement effective consumer food waste prevention campaigns. For Goal 5 during the upcoming reporting period, we will fully summarize the evaluations gathered at the end of the first year's webinar series. We will continue the webinar series in September 2025. Over the summer, the Rutgers team will be facilitating interviews to assess individuals' interest in joining a consumer food waste community of practice focused on developing confidence and competency in conducting and assessing household food waste reduction campaigns. The interviews will be conducted via Zoom. From these interviews we hope to gauge interest in an active community of practice in addition to the monthly webinars. Questions included in these interviews will address how other communities of practice have been successful, what participants are looking to gain by participating and how to structure the community of practice to make it successful. We will also work with a key non-governmental organization in the food waste space to canvass for more potential participants for the Community of Practice.

Impacts
What was accomplished under these goals? Goal 1: Identify and refine educational messages and materials appropriate for a household food waste reduction campaign that can meaningfully reduce the amount of wasted food created among U.S. households. Under goal 1 during this reporting period, we worked with officials from the city of Columbus, Ohio, our first partner city, to identify and refine educational messages and materials appropriate for a household food waste reduction campaign. We selected materials from the 'Save More Than Food' campaign, which had been developed by the Central Ohio Food Waste Initiative, that were then updated and refined. A series of three postcards were created where all messaging was available in three languages (English, Spanish, Somali). The first messages presented a challenge to undertake six actions that support food waste reduction (putting dates on leftovers, sticking to a grocery list, keeping older food items at the front of the refrigerator, eating leftovers, freezing food that won't be eaten in a timely fashion, noting items in storage before shopping). The second message provided tips on storing dairy, leafy greens, fruit and fresh meat and seafood. The third message provided information about date labels. All messages emphasized how much money the average household spends on food that is never eaten (~$2000/year for a family of four). Goal 2: Conduct and assess pilot household food waste reduction campaigns in three cities in the United States. Under goal 2 during this reporting period, we began the process of conducting and assessing a household food waste reduction campaign with our first partner city of Columbus, Ohio. Planning was begun for efforts with the other two partner cities of Denver, Colorado and Tampa Bay, Florida. Goal 3. Anticipate challenges a national household food waste reduction campaign would encounter during a national roll out. Goal 4. Project the food waste reduction potential and cost-benefit ratio of different national strategies for a household food waste reduction campaign. No progress to report under Goals 3 and 4 for this reporting period. Goal 5. Develop an integrated Extension education program based upon current best practices and refined based upon the campaign pilot study findings to prepare personnel in city, regional and state governments and non-governmental organizations to implement effective consumer food waste prevention campaigns. Under Goal 5 during the reporting period, we developed and delivered a webinar series that showcases the efforts of Extension groups, university researchers, and other leaders in the food and sustainability industry who are making significant strides in combating consumer food waste. This year was the first year of the webinar series and it ran from October 2024 to May 2025 (the reporting period ends on March 31, 2025 and numbers will reflect only the reporting period). Over the course of these 8 months the series featured leaders in the sustainability industry such as Too Good to Go and Unilever, leaders in food waste innovations such as ReFED, leaders in municipal food waste reduction programs such as the City of Denver and Washington State, and many more. Topics included community education, food donation, food safety, state and city waste reduction programs, industry food waste prevention campaigns, food recovery apps, and food waste innovations. During the reporting period, the webinar series connected with 704 personnel in city, regional and state governments and non-governmental organizations across the United States as part of an inaugural webinar program with 44 people becoming formal members of the Consumer Food Waste Community of Practice website group. Throughout the Consumer Food Waste Webinar Series, the audience was encouraged to complete surveys via Zoom poll or Qualtrics. These surveys were conducted to gain participant feedback. The first webinar in October launched with strong initial engagement, attracting a diverse audience across sectors. During the launch event Zoom poll, participants were asked about their familiarity with existing consumer food waste campaigns. Of the 122 respondents, 16% (n=19 respondents) reported being very familiar, 63% (n=74 respondents) were somewhat familiar, and 21% (n=29 respondents) were not familiar at all, indicating the series drew both seasoned professionals and newcomers to the topic. The majority of participants, 71% (n=84 respondents), indicated that their current roles involve work related to food waste, while 29% (n=35 respondents) did not. Participants represented a wide range of sectors. Outreach was most effective through the Extension Foundation, which accounted for 64% (n=124) of launch event participants, followed by Rutgers University/Ohio State University at 19% (n=36 respondents), EPA Community of Practice at 7% (n=13 respondents), USDA at 6% (n=12 respondents), and local Cooperative Extension offices at 6% (n=11 respondents). Social media and other sources accounted for the remaining 8% (n=15 respondents). The Mid-Point Qualtrics Survey showed sustained participation of individuals from multiple sectors. In this mid-point assessment, a total of 51 responses were captured. Of the 51 respondents, 49% indicated that they or their organizations were actively pursuing food waste-related programming, while 51% were not. Regarding relevance, 20% of respondents rated the webinar series "somewhat relevant," 53% rated it "relevant," and 48% rated it "very relevant." Overall, Year 1 evaluation data indicates that the Consumer Food Waste Webinar Series successfully engaged a broad audience and consistently delivered relevant content. The consistently high relevance ratings and strong interest in continuing into Year 2 demonstrate the value of this series as an educational and networking resource for professionals addressing consumer food waste. There are currently 44 members in the Consumer Food Waste Community Practice Website hosted by Extension Foundation, which is available online at https://connect.extension.org/g/cfw-cop. This website currently consists of summaries of the webinar series, a calendar of events, blog posts for each webinar summarizing the key points, and links to recordings of the webinars.
