Vitamix’s Countertop Composter Turns Table Scraps Into Plant Food

I have a new box-shaped gadget in my kitchen that takes the food you put in it and turns it into something akin to soil. This is the Vitamix FoodCycler FC-50, a cubic-foot machine with a cylindrical inner chamber that’s about the size of a beach bucket. Fill that bucket with food scraps, let it churn away for several hours, and open it to find something that looks like dirt, extra large fish-food flakes, or some combination thereof. My wife Elisabeth keeps a yogurt container labeled “Fresh Dirt” next to the FoodCycler to store its output. Sometimes the output smells like the faint whiff of trash in a city you’ve never visited. Sometimes it almost smells pleasant. Elisabeth, who’s been on a kombucha-brewing kick lately, did a batch using just the scobys and spent tea leaves, and it all came out smelling like an exotic scent that a parfumier might fold into an eau de cologne.

I immediately got lost in figuring out who this device is made for. Chez Joe in Seattle, for example, we have a city bin for yard and food waste. The trash truck picks it up and carts it away every Thursday. I keep a compost bucket on the kitchen floor, along with a mini version of it next to my prep area. I also have a bag in the freezer with chicken bones and scraps like leek greens, onion tops, and Parmesan rinds, and every few weeks when the bag fills up, I turn its contents into a couple quarts of stock. Growing up in New Hampshire, we’d wing corncobs into the woods from the back deck, and all other veg scraps went into the expansive compost pile at the back edge of the yard. If Mom and Dad needed dirt for their good-sized garden, they’d just dig up a bit. Now, when I need dirt for my rooftop planters, I buy a new bag at the hardware store.

In these cases, the FoodCycler would have limited value. I don’t think there’s no use for it, but once I had it in my kitchen, I realized it’s only going to serve a tiny little niche—and I can’t quite figure out who fits inside that niche. Perhaps you’re in a suburb where there’s no food-waste recycling program, and you’re tired of throwing cooking scraps in the trash. Maybe you want to experiment in making some sort of super compost, and the thought of a $300 gadget is more appealing than a $10 bag of dirt from Lowe’s. It could be that you don’t have room for a compost pile or you want something to feed to your indoor gardening project during a frosty winter.

Composting is a good thing. It doesn’t eliminate the problem of food waste, but it does something productive with what might otherwise end up fertilizing an old couch at the dump. It feeds your soil, adding nutrients that make plants happy. Technically, the end product of composting is called a “soil amendment” or “nutrient source,” though Vitamix refers to the FoodCycler’s output as “fertilizer.”

I called Andy Bary, a soil science researcher at Washington State University. He’s also coauthor of a great, short “Backyard Composting” bulletin that I plan on sharing with all the gardeners in my life. He quickly homed in on safety.

The end product of composting done wrong can transmit pathogens into the food you grow in it, and that is lettuce you do not want to eat. Regular garden compost goes through a phase where a well-tended pile will get up into the low- to mid-hundred degrees Fahrenheit for several weeks, then “cures” at around 100 degrees for another few months. If there are pathogens in the heap, they are cooked or dissipate over a few months. I went down quite a rabbit hole trying to figure out if a several-hour cook in the FoodCycler was enough to cook out any pathogens. According to the folks at Vitamix, each batch spends five to eight hours at or above 158 degrees Fahrenheit, which Bary said “looks good for me to cover pathogen reduction.”

Bary also pointed out that “very few” backyard compost piles get up to the right temperatures (they’re often too small to get hot enough), but if you wait 60 to 90 days, anything bad will dissipate and you can use the nutrient source without worry. Leaving meat products, especially chicken, out of your compost will save you headaches and bellyaches.

You can put some animal products—like chicken bones and other scraps—in the FoodCycler, but I learned to proceed with caution. I made the mistake of sprinkling some around my parsley, and the soil grew mold to emphasize my error. This is the kind of stuff you should turn into the soil.
