Smart Composters Are Heading to Retail, But Will Consumers Bite?

Earlier this month, Costco shoppers in select cities across California and Washington State may have stumbled upon a product demo for an item called Lomi. This white countertop appliance, roughly the size of a sewing machine, sat atop a table adorned with a tablecloth, with boxes stacked high just behind.

The images on the tablecloth hinted at the machine’s purpose – perhaps it was a pressure cooker? An air fryer, maybe? The only way to truly discern the machine’s function was to request a demo from one of the beaming representatives or squint and read the sign that proclaimed “Lomi, Smart Waste Composter, $449.99”.

Don’t get me wrong – The very presence of a compost machine at Costco built to help food scraps avoid the landfill is a good thing, a possible sign that better management of food waste is inching toward more mainstream acceptance. But I still had to wonder: will consumers bite on a machine whose main function is to process food waste into something that can be used as fertilizer?

How Big Is Home Composting?

The answer to that question may lie in how many people want to compost their food scraps but don’t currently have an easy way to do it or access to a curbside compost service.

Approximately a quarter of US citizens aged 30 to 59 years own a compost bin in their homes. That number dips to 14% for those over the age of 60, and rises slightly to 32% for those under 30. One reason for these relatively low numbers is that only 27% of households in the US have access to curbside compost pickup. Curbside pickup is crucial because, unless someone is an avid home gardener, they likely have little need for home-generated compost. By offering curbside compost pickup, local municipalities make the diversion of food scraps as simple as recycling your cans and bottles or disposing of your garbage.

However, with a home compost appliance, anyone can compost food in their kitchen and either sprinkle it on their garden or discard the processed scraps into a patch of soil on the side of their yard. Some products, like the Mill, offer a pickup service for processed food scraps (which they turn into chicken feed) via mail-in packages.

But Will Consumers Bite?

All of this brings us back to the question of how many people would be willing to buy a home composting appliance. Past studies indicate that a majority of consumers are open to using home composting services if they’re readily available, but most aren’t prepared to pay extra for a curbside pickup service. And even when folks say they will compost if access is available, in practice, they don’t always follow through.

However, I suspect that these products target a different type of consumer: the home composter with a purpose. This includes the home gardener looking to create their own compost and the food waste warrior looking for a way to reduce their carbon footprint. For those that fit one or both of these descriptions, they would likely welcome a Lomi or another smart home composter into their kitchen.

That is if they can afford one. The Lomi is $449 for the basic option, plus the extra cost to periodically buy the compost pods with microorganisms that speed up the process of breaking down the food. The Vitamix FoodCycler FC 50 costs $349, plus the cost of filters every couple of months. The Mill, whose makers prefer it not to be referred to as a composter because they turn the scraps into animal feed (though we still categorize them as composter), charges a monthly subscription of $33 for the machine and the pickup service for the processed food grounds.

None of these are cheap, especially for a fairly new product category like smart composters, which is probably why Lomi felt the need to start sending demo teams into markets in California and Washington to show people what these products are all about. When I walked up to the Lomi table and asked them about the product, the demo leader was enthusiastic and let me know how to use it.

In the end, I think this market will be an interesting one to watch, in part because it’s so new. It will take some time to teach consumers the benefits of these products, and once they do, we will learn just how many folks are willing to pay for a machine to process their food scraps.

Mill Wants You to Create Chicken Feed Out of Food Scraps

Want to stop sending food waste to the landfill?

A new device and service from a company called Mill will help you do just that while also letting you feed a chicken or two while you’re at it.

Debuting today, the Mill kitchen bin, a new eponymous device from a company founded by a couple of ex-Nest execs, will take your food waste and shrink & “de-stink” it as it turns into what it calls Food Grounds, something the company says is a “safe and nutritious chicken feed ingredient.”

Here’s how it works:

You sign up for a Mill “Membership,” a $33-a-month subscription service that includes a kitchen bin and a pickup service for the processed Food Grounds. You connect the Mill to Wi-Fi, activate it using the Mill app, and start tossing in your food scraps. Once the bin is full, you put your Food Grounds into a prepaid box and schedule a pickup with the Mill app.

While it’s tempting to call the kitchen bin one of a new cohort of smart food composters, Mill wants you to know that its box is definitely not a composter. The Food Grounds “aren’t compost,” says Mill, because instead of having the food sit and get eaten by microbes, it’s processed into an edible chicken feed ingredient they say can be put back into the food system.

Still, aside from the chicken feed system, the Mill isn’t that different from some of the other composters we’ve written about. Like the Lomi and the Kalea, the machine accelerates the shrinking and drying of the food into something other than the original food waste you dropped into the container.

The framing of the Mill is primarily about sustainability and reducing food waste, and it’s a positioning that makes sense. If we’re going to throw food out, it’s better to have those scraps turned into something that can feed chickens or your local garden than end up in a landfill.

That said, the optimal solution for food is not to have it end up as food waste at all, but instead, have it eaten by humans. That’s why I’m hoping the Mill team’s next product will be something that helps us preserve food from entering a waste bin altogether.

For those interested, Mill is taking reservations now and plans to ship the kitchen bin this spring.

Smart Food Waste Composters Are Here. Here’s a Look at Five of Them

Food waste sucks, but no matter how hard we try, most of us end up throwing out some food.

So if and when food does go to waste, the best thing to do is to make sure it doesn’t end up in a landfill. In some locations (like where I live), the city offers green bin programs with curbside yard and food waste pickup. But what option do those without city-run green bin programs have?

Composting! That’s right, no longer just for hardcore gardeners or your parents’ hippy friends, composting is becoming more popular as a way to avoid filling our landfills with carbon gas-emitting food waste, while also creating a rich food source for the home garden.

The problem? Composting takes time. In fact, it can take you up to a few months to fully compost food in a traditional composter (and that’s even after you buy worms!).

But now, there may be another answer…

Welcome To The Age of The Smart Food Waste Composter

The good news is we’re seeing a new wave of smart, automated compost systems that help the user turn food waste into compost. These new systems can compress composting time from months to days. They use internal compressors and grinders to break down the food and often have sensors to optimize the internal environment to foster microbe and nutrient growth.

Some come in economically sized countertop systems, while a couple of others look like a kitchen garbage bin or sit under your sink and connect to your plumbing system.

Most of these systems are either still in development or are just beginning to ship. And while I haven’t tested any of them yet and can’t vouch for their effectiveness, I do think – if they work as promised – these systems could potentially make composting a much more viable option for millions of households.

Here’s a look at five early entrants into the smart food waste composter category.

The Lomi

The first look at Lomi

The Lomi is a countertop system that compresses and grinds food waste into compostable material. The user drops food waste into the system and pushes a button, and the Lomi will turn the waste into compostable material in less than a day. The system has an Eco and Express mode; Eco takes about 20 hours and will produce a densely rich nutrient compost, while the Express mode takes 6 hours and produces a “neutral natural fertilizer”.

One of the cool features of the Lomi is it will compost compostable plastics. Throw in those compostable plastic containers or cutlery and the system will churn it into fertilizer. The Lomi uses a replaceable carbon filter system to reduce odor, and filters need to be replaced every 3-6 months.

The Lomi is from Pela, a company that made a name for itself with compostable material phone cases. When it launched on Indiegogo this year, the Lomi easily broke the record for the most-backed product in the food waste category with nearly 19 thousand backers and $6.9 million in raised funds.

Those interested can still buy the Lomi for $399 on Indiegogo and the company says it will ship in January 2022.

The Vitamix FoodCycler FC-50

Introducing the Vitamix® FoodCycler® FC-50!

While many of the new smart compost systems are from startups who launch their products on crowdfunding platforms, the new Vitamix FoodCycler FC-50 is from a name well known for its home blenders.

Here’s how Vitamix described the FoodCycler when they announced it last year: The FoodCycler FC-50 is lightweight, easy-to-use, odorless and compact. It comes with a small food-waste collecting bucket that can be moved around the kitchen – from countertop to sink – when preparing meals. The bucket is dishwasher-safe and comes with a lid, making it easy to keep the cast-iron bucket on your kitchen counter and the FoodCycler unit in a garage, laundry room or pantry..

The FC-50 can process a bucket of food in 4-8 hours. In addition to vegetable and fruit scraps, the unit will process meat, dairy products, and even bones from bones from fish or chicken.

The Vitamix FC-50 is available today for $379 on Amazon.

KALEA

KALEA automatic kitchen composter creates more out of your food scraps – start your home composting

Unlike the Lomi or the Vitamix FC-50, the KALEA home composter sits on the floor and looks like a small garbage can. The KALEA has two main components; Food is dumped into the upper chamber, where it is shredded, and its moisture is removed (there’s also a carbon filter to remove odors). Once shredded and dried, waste then drops into the second chamber where the machine creates the optimal temperature, oxygen levels and humidity conditions to turn the waste into compost. The processed compost is ready in 48 hours and dropped into a collection tray at the bottom of the machine.

The KALEA launched on Kickstarter, and while it didn’t raise the eye-popping amount of the Lomi, the creators were able to raise a respectable €485 thousand. The first backer units were supposed to go out in December of this year, and if the updates on Kickstarter are any indication, it seems like things are mostly on track. However, if you weren’t one of the early backers and wanted to order a KALEA, you’ll have to wait until July of next year, and it will set you back €729 ($850).

Tero

Tero - The revolutionary alternative to composting

The Tero is a countertop home compost machine that turns food waste into compostable powder in 3-8 hours. Like some of the other countertop machines, the Tero compresses and grinds the food, and the company claims it reduces the total volume of the material by 90%.

The product comes in two versions, the Tero and the Tero Plus. The Tero Plus does the same amount of food as the base unit, but also comes with Wi-Fi connectivity and an app that lets you track how much food waste you have processed and order filters.

The Tero was funded via a successful Kickstarter campaign and units are shipping now to early backers. You can preorder a Tero on the company’s website.

Sepura

The Sepura is unique in that it is a system that replaces your under sink food disposal system and automatically separates food waste into a collection bin. The home owner or a plumber installs the Sepura system by connecting the separator unit to the sink. A separate collection bin connects to the processing unit, which takes about 8 seconds or so to grind the food and separate solids from liquids. When the collection bin is full, the user detaches it and puts the processed food into a compost pile or into a green bin.
