Impact
Villalobos and the research team shared the results in several ways to engage numerous stakeholders. This outreach included hosting community-wide training workshops, engaging with social and print media and publishing several peer-reviewed articles.
In conducting this research, Villalobos uncovered other logistical challenges that produce growers face in getting their products to markets. Specifically, produce growers face first-mile problems, meaning they struggle to secure refrigerated transport for their harvests. Often their harvests are small and securing a commercial refrigerated truck for a smaller harvest is prohibitively expensive. Growers are also concerned about potential contamination if multiple harvests are combined in a single truck and some growers live in rural areas that commercial trucks do not service.
Building on their FFAR-funded research, Villalobos developed a concept for aggregating multiple harvests in separate refrigerated cubes, called Mini-Containers. The integrated storage transportation system aggregates Mini-Containers, which are stackable, insulated containers, powered by traditional as well as solar-based sources, that create controlled environments to extend the shelf-life of perishable products. The Mini-Containers can be delivered before or during harvests and refrigerate the produce until a truck that collects multiple containers can transport them to the intended market. Due to Villalobos’ outcomes from the FFAR funded research, the City of Phoenix provided Villalobos $95,000 to build a Mini-Container protype. The research team then received a $250,000 National Science Foundation grant to improve the central refrigeration unit used to efficiently maintain the Mini-Containers at the right temperature.
Fresh Cubes can refrigerate produce without a power source for about six hours. The research team invented a portable solar farm, which they are currently patenting, to power refrigerators postharvest in rural areas for longer.
Villalobos noted that there is considerable interest in continuing and expanding the research.
