“We get every thing you’ll find in Aisles 1 by means of 12,” says Mr. Marciniec, web site supervisor of the Agawam Organics Recycling Facility, owned and operated by Vanguard Renewables.

Why We Wrote This
A narrative centered on
Many U.S. communities have taken steps to cut back meals waste in recent times, however seen little progress. One state has really managed to tug it off. Right here’s how.
Because the expired ice cream funnels right into a turbo separator, Mr. Marciniec watches the machine strip meals from its packaging. The natural waste is then trucked to a dairy farm, the place it’s blended with cow manure and processed into renewable pure fuel.
“It’s actually an important circle,” says Mr. Marciniec. “Meals begins on the farm, and our farms flip it again into vitality. Farm to desk, then again to farm.”
Take into account these day-old strawberries, gone too quickly. Whether or not they spoil on a grocery store shelf or at the back of the fridge at dwelling, they typically find yourself in the identical place: a landfill.
Amenities like this one, which might course of as much as 250 tons of meals waste each day, replaces guide work usually executed by hand or not executed in any respect.
That’s an important step in diverting waste away from landfills. Individuals throw out about 40% of meals yearly – a waste of each cash and pure sources. Lowering meals waste can improve meals safety, promote useful resource and vitality conservation, and deal with local weather change.
The Bay Sate has change into a pacesetter in lowering meals waste. Actually, it’s the one state to considerably accomplish that – to the tune of 13.2% – in keeping with a 2024 examine. Massachusetts was among the many first 5 states to enact a meals waste ban in 2014. (The others had been California, Connecticut, Rhode Island, and Vermont.)
“The legislation has labored very well in Massachusetts,” says Robert Sanders, an assistant professor of selling and analytics on the College of California San Diego and co-author of the examine. “That’s attributable to three issues: affordability, simplicity, and enforcement.’”

Changing waste into gasoline
If meals waste had been its personal nation, it will be the third-highest emitter of greenhouse gases after China and the USA.
It’s additionally the most important class of waste – at 25% – despatched to landfills in the USA. In 2019, 66 million tons of meals waste got here from retail, meals service, and households. Round 60% of this waste was despatched to landfills, in keeping with the Environmental Safety Company.
Vanguard Renewables focuses on turning natural waste into renewable vitality. The Massachusetts-based firm companions with dairy farms to transform meals scraps and manure into biogas by means of anaerobic digestion.
Microorganisms in cow manure digest natural matter, releasing biogas – a mixture of methane and carbon dioxide. The fuel is captured in giant metal vats on the farm and refined into renewable pure fuel, which can be utilized to warmth houses and energy buildings.
“Principally, we harvest bug farts,” says Mr. Marciniec with fun. However the outcomes aren’t any joke. Every of Vanguard Renewables’ 5 digesters produces sufficient vitality to warmth 1,600 to three,500 houses per 12 months.
Since 2014, Vanguard has processed greater than 887,000 tons of meals waste in New England, producing sufficient pure fuel to warmth 20,000 houses for a 12 months. By 2028, the corporate plans to have greater than 50 programs throughout the nation.

Baking meals restoration into “each a part of the enterprise”
In western Massachusetts, Amherst Faculty has change into a mannequin for limiting meals waste on the supply. Final 12 months, it was acknowledged because the winner within the zero waste class within the Campus Race to Zero Waste Case Research Competitors.
“The purpose has been to push us aggressively to ensure every thing is compostable,” says Weston Dripps, director of sustainability. To realize that, the college has phased out single-use plastics, to-go containers, and even canned water, changing them with refill stations and compostable supplies.
In 2023, Amherst Faculty generated 238 tons of meals waste – roughly 4 to five tons per week. However as a substitute of ending up in landfills, Vanguard collected 100% of that waste and processed it at its Agawam facility.
That whole contains each pre-consumer waste – akin to kitchen scraps from meals prep – and postconsumer waste, like leftovers scraped off plates within the eating corridor and campus cafés. “To actually have a clear waste stream, we’ve to deal with the entrance finish,” says Mr. Dripps.
Amherst’s method goes past composting. Every month, the college donates 2,000 to three,000 kilos of frozen surplus meals to the the Meals Financial institution of Western Massachusetts, guaranteeing edible meals reaches these in want.
Industrial companies, too, are discovering methods to chop down on waste. Maura Duggan, founder and CEO of Fancypants Baking Co., is aware of firsthand how a lot meals can go to waste within the meals trade. Her firm produces a whole bunch of hundreds of cookies every week.
At its Walpole facility, Fancypants has giant totes from Vanguard, which accumulate burnt cookies, meals scraps, and something that may’t be donated or bought. Final 12 months alone, Fancypants diverted about 22 tons of waste.
Ms. Duggan says the totes function a each day reminder that sustainability isn’t an afterthought – “it may be baked into each a part of the enterprise.”

“I’m positive we are able to do a greater job”
For the commonwealth to fulfill its 2030 purpose of lowering meals waste disposal by 780,000 tons per 12 months, it has to double its fee of waste diversion.
Again in Agawam, Mr. Marciniec passes by 275-gallon totes filled with leafy greens. Every single day, he faces the fact that Individuals waste 92 billion kilos of meals a 12 months – sufficient to make 145 million meals.
“It actually makes you concentrate on the issues we take as a right,” he displays.
