Behaviors classified as “food waste reducing” are italicized; behaviors classified as “food waste promoting” are non-italicized 6.4 Reported Frequency of Food Preparation Behaviors.

Resorts pay for the storage vi Figures and hauling of trash, but seldom pay tipping fees to manage landfills. The “underwater” or hidden costs of solid waste on islands include control of flies and rats, groundwater pollution, air pollution and public health impacts 17.2 Visual illustrating the location of the trash compactor in relation 276 to the food and supply delivery station for Sandals Emerald Bay. The unsorted trash adjacent to the food loading dock creates challenges with food safety and hygiene 17.3 Exuma Regional Sanitary Landfill solid waste annual arrivals 277 from 2006 projected through 2016.
