Tuesday evening at Green Star was scheduled as the last public collection of 2026 for Fairbanks' first commercial-scale composter. The Earth Flow IM-40 at Golden Heart Waste Management had its ribbon cutting on September 25. From that ceremony to the final drop-off, its first fall season lasted 25 days. Public drop-offs covered just 15 of those days before the cold paused the composter.
That short first season tells you how the program works in the Interior. An automated machine sealed inside a 40-foot shipping container still runs on the same calendar Interior gardeners have always followed. Scraps from November through breakup have to go somewhere, and households that use those months to get ready will be first in line when the spring 2027 pop-ups start.
Three drop-offs in October
The Fairbanks Soil and Water Conservation District got the federal funding for the project and partnered with Golden Heart Waste Management, a locally owned waste hauler, to run it. The money came from the USDA Natural Resources Conservation Service's Compost and Food Waste Reduction Cooperative Agreements program. The district planned monthly drop-off events where residents could bring three-gallon buckets of food scraps to a pop-up site at Green Star of Interior Alaska.
The first fall went like this:
- Friday, September 25: Ribbon cutting at Golden Heart Waste Management.
- Monday, October 5, noon to 4 p.m.: First public drop-off at Green Star, 2134 Texaco Ave.
- Monday, October 12, noon to 4 p.m.: Second drop-off, with a note to watch for spring 2027 dates.
- Tuesday, October 20, 4 to 6 p.m.: An extra drop-off. Green Star announced it by saying the temperatures looked like they would allow "one more food waste collection pop-up before GHWM has to shut down their composter."
The schedule added up to ten hours of public collection in the composter's first fall. The machine itself can handle far more. The USDA NRCS announcement says the Earth Flow can process up to 1,000 pounds of organic waste a day, turning food scraps, yard trimmings and biodegradable packaging into compost.
A machine built for remote places, running on a Fairbanks calendar
Green Mountain Technologies designed the Earth Flow IM-40, and USDA describes it as fully automated and suited to both urban and remote communities. The manufacturer's Earth Flow page lists automated aeration and mixing inside a shipping container or a vessel built on site. Andrew Rossow, general manager of Golden Heart Waste Management, aimed higher than Fairbanks. In the USDA release, he said the goal is "to develop a composting model that can serve other communities across Alaska, including villages."
Green Star gave temperature as the reason for this year's pause. The University of Alaska Fairbanks Cooperative Extension Service has been explaining the cold-weather limits on composting for years. In Composting in Alaska, Extension says the bacteria that start a pile need liquid water, and "a small, moist pile freezes before the bacteria have a chance to heat the pile up." Extension also says Alaskans who compost year-round tend to have large amounts of unfrozen material, such as farmers with fresh manure every day. Most gardeners start in May or early June.
Large-scale winter composting does exist here. The same Extension publication says that even in the depths of winter, compost is being made every day at the Golden Heart Utilities Wastewater Treatment Plant. That operation keeps going through winter. The new food-scrap program pauses until spring, and so does a backyard pile fed one kitchen bucket at a time.
Felicia Gunn, compost coordinator with Fairbanks SWCD, put the program's purpose in civic terms in the USDA NRCS release:
"Transforming waste into a resource gives us an opportunity to build our template for a healthier, more resilient Fairbanks."
What goes in the bucket, and what stays out
Before the spring pop-ups, learn the list. It's narrower than many backyard composters expect. Green Star posted the Earth Flow's accepted materials with the October 20 announcement.
Accepted:
- Fruit and vegetable scraps
- Coffee grounds
- Crushed eggshells
- Bread and pasta
- Nuts
Not accepted:
- Meat, fish and bones
- Dairy
- Oils and grease
- Pet waste or kitty litter
- Plastic, stickers or metal of any kind
Produce stickers are the easiest to miss. One left on a banana peel puts plastic in a bin meant only for food.
Your winter options, by the numbers
Between now and spring, Fairbanks households have two realistic ways to handle scraps without the landfill. UAF Extension covers both.
An indoor worm bin. Extension's Composting with Worms recommends keeping the worm box where you can control temperature and moisture, ideally between 55 and 77°F. The worms eat many of the same things the Earth Flow takes, including fruit and vegetable scraps, coffee grounds, eggshells and bread. In a Fairbanks winter, that temperature range means a basement, heated garage or utility room.
Plan the size around the numbers. Extension says one pound of worms can process about 3.5 pounds of scraps a week, and an average family of four produces about six pounds of kitchen waste a week. At those rates, a family of four would need about 1.7 pounds of worms to keep up. A starter bin with one pound of worms will handle a little more than half of that household's scraps.
An outdoor pile that waits for breakup. Extension says that in Alaska, a pile often freezes after its active hot phase, and its final maturing stage starts in spring "when the pile thaws and liquid water is again available for the microbes." A pile started in late summer can finish its hot phases even as air temperatures drop below freezing, as long as it is big enough. A small pile freezes sooner because the material inside has less mass to hold heat. If you're starting a pile now, expect it to sit frozen until spring and then finish once it thaws.
Either way, Extension's advice for Alaska is to plan on using this year's compost in next year's garden. The Earth Flow is on a similar schedule, starting again with the spring pop-ups.
Getting set for the spring 2027 pop-ups
Green Star has told residents to "stay tuned for spring 2027 pop-up dates," and those dates haven't been set yet. You can get ready before then:
- Get a bucket now. Three-gallon buckets are available at the Fairbanks Soil & Water Conservation District, 590 University Ave., at Green Star, or at the pop-ups. The district's contact page lists the full address as Suite 2, Fairbanks, AK 99709, and the phone number as 907-479-1213.
- Any container works. Green Star says buckets are optional, so you can bring scraps in whatever you'd like.
- Know where to go. Drop-offs happen at Green Star of Interior Alaska's offices, 2134 Texaco Ave., Fairbanks, AK 99701.
- Follow Green Star. The fall dates were posted on Green Star's website, and the October 20 date also had a Facebook event. It went up just a week ahead.
USDA has also described what the compost is for. Austin Shero, the NRCS assistant state conservationist for field operations, said in the agency's release that the project "will increase compost access for local producers, and it will improve soil health and add value to local gardens." Interior gardens are short-season, and a better soil supply makes a real difference to the people growing in them.
The News-Miner covered the launch in early October and reported that Fairbanks residents would be able to turn their food waste into compost that benefits the community. After one fall, the program has a drop-off site, a list of accepted materials, buckets to hand out and a plan to return in spring.
