In Vermont, approximately 160,000 tons of food waste is generated annually and only an estimated 20% is currently composted. Wasted food means wasted money for Vermont businesses and households, and unintended impacts to the environment through production, storage and transportation of food, and ultimate disposal of the waste in landfills.
Historically, the waste management system in Vermont has been driven by consumer convenience and large-scale operations. Food scraps have been mixed with garbage and carted to landfills where their inherent value to replenish our soils is not only wasted but contributes to environmental degradation through emissions of greenhouse gases that are not captured at our operating landfills. Methane is a potent greenhouse gas, up to 20 times more effective at trapping heat than carbon dioxide, and landfills account for the single largest human-made source of methane in the earth's atmosphere.
Vermont is in a unique position to lead the nation in diverting 100 percent of our food waste from landfills by 2020 -- reducing our ecological impacts and investing in our local agriculture movement.
Fortunately, we have a solid infrastructure in place for the redirection of safe, wholesome excess food or leftovers; it occurs through churches, food shelves and pantries. Local partnerships between generators (such as grocers, schools, and food processors) and farmers also prevent unwanted food from going to waste. Additionally, a number of commercial and on-farm compost operations across the state plus community and backyard composting also have a foothold. This infrastructure forms a base upon which to build and expand a thriving food and nutrient redistribution system in our state. This can encompass the social, environmental and economic impacts related to collecting food residuals of all types and redirecting them in keeping with the hierarchy established in the legislation of reducing at the source, feeding hungry people, feeding animals, and industrial and compost uses before disposal.
The Vermont Agency of Natural Resources, the U.S. Environmental Protection Agency and Vermont Technical College's Center for Sustainable Practice will focus on supporting this groundbreaking legislation's implementation at the upcoming GroundWork Conference on December 4, entitled Reducing Food Waste through Source Reduction. It offers one opportunity to consider the many implications of this legislation, and various models for how businesses and individuals may comply with the new law.
With ongoing analysis, inclusive communication, and continued vigilance, we can reduce waste and use waste that is generated to rejuvenate our soils for increased food production, an improved environment, and a healthier world.
