Reducing Food And Packaging Waste Through Developing Edible Fruit Based Packaging Prototypes, Melanie Thatcher Jun 2016

Reducing Food And Packaging Waste Through Developing Edible Fruit Based Packaging Prototypes, Melanie Thatcher

Materials Engineering

Packaging is used to contain, preserve, protect, and advertise both manufactured and natural products. In 2013 it was reported that over thirty percent of solid waste in the United States was from packaging. One way to reduce the impact of packaging on the environment is to create a solution that is edible and sourced from a waste or secondary food product that is not currently being utilized. Food-contact packaging made from recycled materials must meet strict U.S. Food and Drug Administration (FDA) regulations to be utilized as raw material for packaging. Fruit pomace is a candidate material since it may …
