TL;DR: Lomi processes food scraps into a soil amendment you keep at home, Mill dehydrates scraps and ships them back to be turned into chicken feed, and a traditional countertop bin is just a scrap catcher that still requires you to actually compost the contents yourself — each wins on a different axis of convenience, cost, and what happens to the waste.
How Each One Actually Works
These three products aren't really competing on the same job. A traditional bin is a holding container — you still need an outdoor pile, a municipal green-bin program, or a neighbor's compost heap to finish the job. Lomi and Mill are both electric countertop appliances that grind and dehydrate food scraps overnight, but what comes out the other end, and what you're expected to do with it, is genuinely different between the two.
Lomi: Grind, Dehydrate, and a Soil Amendment — Not Finished Compost
Lomi, made by Pela, runs food scraps through a grind-and-dehydrate cycle (Lomi offers a few cycle lengths depending on what's in the load, with longer cycles for approved bioplastics or garden-ready output). The result is a dry, dirt-like material. Here's the part that trips people up: that output is a soil amendment, not finished compost. Real compost is the product of weeks or months of microbial decomposition that breaks food down into stable, nutrient-available humus. Lomi's cycle is mechanical and thermal, not biological — it dehydrates and shreds in hours, not months — so what you get is dramatically reduced in volume and shelf-stable, but it still needs to be mixed into existing garden soil (not used on its own) to actually benefit plants. Odor is controlled with a carbon filter that needs periodic replacement, and the unit runs on standard household power.
Mill: Dehydrate, Ship Back, Turn Scraps Into Chicken Feed
Mill, founded by former Nest CEO Matt Rogers, works on a similar mechanical principle — an overnight cycle that dehydrates and grinds food scraps into dried "food grounds" — but the business model is the real differentiator. Mill's whole pitch is a closed loop: you can ship your accumulated grounds back to Mill in prepaid boxes, where they're processed into an ingredient for chicken feed rather than composted. You can also keep the grounds at home and use them in soil the same way you'd use Lomi's output. Mill has historically leaned on a subscription model (device plus a recurring membership fee that includes the shipping program) rather than a simple one-time purchase, which is worth knowing going in — it's a different financial commitment than Lomi's buy-it-once approach.
Traditional Countertop Bin: The Zero-Electricity Baseline
A basic charcoal-filtered scrap bin — the kind that sits by your cutting board — does none of the processing Lomi or Mill does. It's just a holding container that keeps fruit-fly odor down until you empty it into an outdoor pile, a municipal green-bin pickup, or a community compost drop-off. It costs a fraction of either electric device, uses zero electricity, and has no moving parts to break. The tradeoff is that all the actual composting work — turning a pile, waiting weeks to months for it to break down, managing moisture and carbon-to-nitrogen ratio — is still entirely on you, or on a municipal program you have to opt into.
Electricity, Odor, and Cycle Time Compared
| Attribute | Lomi | Mill | Traditional Bin |
|---|---|---|---|
| Power source | Standard wall outlet | Standard wall outlet | None |
| Cycle time | Hours (varies by mode) | Overnight, roughly 8+ hours | N/A — no processing |
| Odor control | Carbon filter, replace periodically | Sealed dehydration, minimal odor between empties | Basic charcoal filter in lid |
| End output | Dried soil amendment (mix into soil) | Dried grounds — ship back for feed, or use in soil | Raw scraps — you compost them elsewhere |
| Upfront cost | One-time purchase | Purchase or ongoing membership fee | Low, one-time |
What Actually Happens to the Output
This is the most commonly misunderstood part of both devices, so it's worth being blunt: neither Lomi nor Mill hands you real, garden-ready compost. Lomi's output is explicitly marketed as a soil amendment meant to be blended into existing dirt, not spread on its own. Mill's dried grounds are designed around being shipped back into an animal-feed supply chain — the at-home garden use is the secondary option, not the headline feature. If what you actually want is finished, humus-rich compost you can pot plants directly in, an outdoor bin or tumbler that runs on real microbial decomposition over weeks to months is still the more accurate tool for that job. What Lomi and Mill are genuinely good at is shrinking daily food waste fast, cutting the smell and volume going to landfill, and doing it on a kitchen counter without flies or a backyard.
Our Verdict
If you want the least hands-on option and don't mind paying for an appliance, Lomi is the simpler buy-it-once choice for turning scraps into something you can work into your own garden beds. Mill makes more sense if the idea of your food waste becoming chicken feed instead of landfill methane actually matters to you, and you're comfortable with a subscription. If money is tight or you already have an outdoor compost pile or municipal pickup, a $20–30 traditional countertop bin does the one job it needs to do — catch scraps without smelling up the kitchen — for a fraction of the cost, with the tradeoff that you're still doing the composting yourself.
