The main purpose of the Zero Food Waste Act is to reduce the amount of food waste generated in the United States. The goal is to cut food waste by 50 percent by the year 2035, compared to levels from 2015. This legislation aims to address the environmental impact of food waste, which often ends up in landfills and contributes to greenhouse gas emissions. Key provisions of the Act include the establishment of a grant program managed by the Environmental Protection Agency (EPA).
