A new subscription-based service launched today, but instead of bringing a box of meat or Japanese treats to your door, this one promises to take away your food waste. The creators of the service, called Mill, hope that it will reduce carbon emissions and help keep kitchens free of nasty smells and flies—all while feeding chickens with your kitchen waste.

The service is based on a trash can with Wi-Fi capabilities. Its creators say that while there are emissions associated with the bin's creation and operation, the life-cycle assessment they ran on it shows that users still come out ahead when it comes to their emissions reductions.

Lots of waste

By some counts, around 119 billion pounds of food are wasted each year in the United States. This takes a toll on the environment, considering the energy that goes into growing, harvesting, packing, and transporting food. According to the World Wildlife Fund, between 6 and 8 percent of human-made greenhouse gas emissions could be eliminated by cutting down on this waste. Not including methane—which is considered 80 times worse than carbon dioxide—food waste and loss accounts for around 170 million metric tons of carbon dioxide equivalent each year in the US alone.

Matt Rogers, Mill’s co-founder and CEO, said he began working on Mill around two and a half years ago after learning about the environmental impact of food waste. “I was completely unaware of how big the problem of food waste was,” said Rogers, who was also the co-founder and chief product officer of smart home company Nest

“So [it’s an] epic, epic climate problem, let alone the fact we're actually wasting food, which everyone's grandma told them not to do,” Rogers told Ars.

Garbage on the go

People can subscribe to Mill for $33 per month with a one-year commitment or $45 per month on a month-to-month basis. You can sign up starting today, and Mill will get you set up in the early spring, Rogers said. The service is available across the US, and the company hopes to expand to Canada at some point in the future.

Mill sends subscribers a specialized garbage bin that connects to an app. The 2-foot-tall bin needs to be plugged in, but it dries and shrinks the garbage and removes odors from food waste, including meat and dairy. Inside, it features paddles and a small heater. When food goes in, the bin moves it around and warms it, drying it out and reducing it in size. “When you dry food out, it gets small and kind of breaks apart very easily,” he said.

After processing, the material ends up looking like coffee grounds, Rogers said. The bin also comes with a charcoal filter to remove smells and a scale that determines how much food is in it. When the bin is full—which takes approximately three weeks, Rogers said—both the device and the app alert the subscriber. Mill provides users with boxes with pre-paid US postage. Using the app, they can book a pickup from the USPS and mail the dried-out organic material back to Mill’s HQ. (Users can also get more pre-stamped boxes for free from Mill through the app). The dried-out food waste doesn’t smell and is much lighter, being devoid of water, Rogers said.
