Many food waste estimates are based on a USDA study completed in February 2014. Though the study finds that 31% of food value is lost, the range may be as high as high as 40% Nationally based on recent data. (USDA study)
Below is information from a local article on food waste using the national study as well as a study data collected in Hawaii.
Food Waste in Hawaii
Hawaii pays some of the highest food prices in the U.S., but we still toss out 237,000 tons of food per year or 26% of the available food supply. This food waste equals over $1 billion or 1.5% of the states GDP. This equals approximately $700 per person (in Hawaii), per year.
Almost half of all the fresh fruit produced or imported into the state is thrown away, while rice and seafood hovers around 40% uneaten.
