HOW IT WORKS
Two chamber designSo clean and easy, you can even compost indoors. Add food at any time into the upper chamber. Heat, mixing, and oxygen help the natural cultures break down the food within days - before odors develop. Push a button to transfer to the tray below. It will continue to compost there for another week, while you fill the upper chamber again. Remove the tray at your conveinence.
No worms, bugs, or trash odorsNatural compost cultures consume the food quickly, without trash odors. They produce a mild aroma like sourdough bread, mushrooms, or straw. Balance the compost by adding sawdust pellets to increase "brown" content, and baking soda to reduce acidity (both are included). An air pump draws air into the machine and out through a powerful air filter.
All new ECO SeriesOur third generation technology is the best yet, with over 50 improvements from the last model. After years of customer feedback, research, and testing, we have the features that everyone has been asking for. Quieter operation, stronger air filter, more capacity, and rugged materials ensure many years of trouble free composting.
Use it anywhereFits inside any standard cabinet (cabinet kit sold separately). Keep it in the kitchen, a garage, or laundry room. Use it indoors or outdoors, even in the snow, rain, or freezing temperatures. Keep the power supply dry with an weatherproof power outlet (available at most hardware stores).
Endless supply of compostEmpty the cure tray when when it is full. You can expect about 1.5 gallons (6L) of finished compost every two weeks, depending on your actual usage. Seventy percent of the initial food disappears into thin air, as the cultures convert it into water which evaporates. What's left is a concentrated compost fertilizer. It's ready for use outdoors, or leave it in a bucket until you are ready to use it.
Good for the gardenFood compost is very high in nitrogen, which is essential for healthy plants. Use it on a garden, lawn, shrubs, trees, or indoor potted plants. Spread over the soil surface, like mulch. Nutrients will gradually enter the soil during watering and annual tilling. One batch is enough for 10-40 sq ft (1-4 sq m) of a lawn or garden, applied once or twice per year. Or use one batch per tree.
Great for the planetEnergy use is just $0.50/month - less than a garbage truck would burn in diesel fuel to haul away the same waste. A NatureMill composter recycles its weight in waste every 10 days, diverting over two tons of waste from landfills over its life. This reduces emissions of methane, a harmful greenhouse gas produced when organic matter decomposes in oxygen-starved landfills. NatureMill is made from recycled and recyclable materials. Every NatureMill composter meets California Energy Efficiency Level IV - the most stringent energy standard in the world.

The Story of CompostingFood is the #1 least recycled of all waste materials. There is just no easy way to recycle food - until now! Our society recycles more and more paper and plastic each year, which shows our potential once a technology is in place to make things easier.
The Biodegradable IronyFood decomposes by itself in nature. However, it is one of the largest components in landfills, accounting for nearly 50% of all municipal solid waste. There is more food in landfills than diapers, styrofoam, and tires — combined.
Landfills are layered deep and saturated with water. No oxygen can penetrate. As a result, even "biodegradable" waste will remain embalmed for centuries to come. Landfills produce methane, a harmful greenhouse gas 21 times more potent than carbon dioxide (according to the US EPA), and leach toxic chemicals into our air and drinking water.
On a more urgent note, we are running out of landfill space—that is, open space reasonably close to population centers. Stories abound of trash barges with no place to dock, ocean dumping, and trash exported to poorer countries. Landfill costs are skyrocketing, which means higher fees (or taxes) for everyone. The organic nutrients present in food and paper waste are removed from the food chain, requiring gardeners and farmers to instead rely on chemical fertilizers to replenish their soil. National and local governments around the world are enacting regulations to limit trash and increase recycling.
Cultures at workMicroscopic compost cultures, which are present everywhere in nature, eat away at organic waste material. Most of the material is converted into water vapor, which evaporates away. Roughly 25% of the material remains in a highly nutrient rich form which re-enters the food chain as a natural organic fertilizer called compost. Of particular value is nitrogen, which is difficult for plants to obtain in a usable form. Compost is also very useful for retaining moisture due to its spongy, fibrous texture. The most important requirement for compost cultures is oxygen - without it they can not survive.
Spread composting and grass-cyclingLeft to itself out in the open with oxygen, compost cultures break down organic matter into fertile soil. In the most primitive form of home composting, simply spread waste out and eventually it will go back to nature. In a process called "grass cycling," just leave grass clippings right there on the lawn rather than collecting them in a bag. They will dry out in a few days and will be hardly noticeable. The process takes a year or more, however, and some organic wastes will attract pets, children, rats, and raccoons. It's fine for grass clippings but not for kitchen compost.
Backyard compostingYou can accelerate and partially contain the home composting process by building a heap, compost bin, or compost tumbler. Compost cultures, already present in most foods or added from a starter pack, eat away at the waste material and produce heat as a byproduct. If the material is piled high enough, heat is trapped inside and can raise temperatures significantly. The heat allows the cultures to work faster and reproduce faster to increase their population, which in turn reduces composting time to a few months or weeks. You can build a home compost heap with just a pitch fork, or use any one of a number of inexpensive or home made compost bins and compost tumblers and tools to keep things organized. Many garden centers sell compost bins and compost tumblers and offer courses on how to compost in your backyard.
But backyard composting has drawbacks. The heap must be at least three feet (one meter) high to generate sufficient heat. A typical compost bin or compost tumbler is not big enough and so sufficient heat is never achieved. And if it is too big, oxygen will not penetrate. The compost must be turned periodically so the cold outer layer has a chance to get inside where it is warm. This is backbreaking and dirty work. Moisture level, acidity, and the carbon to nitrogen ratio must be carefully managed. In most climates, winter temperatures destroy the compost cultures. Most compost bins and compost tumblers are not attractive. Certain foods wastes such as meat, fish, and dairy products, have obvious health hazards and are not suitable for a home composting. You may be surprised to find seeds from a single discarded tomato or apple germinating all over your garden. Besides, not everyone has space for a compost heap. It is the same thing for worm composting and using a worm compost bin, which will be explained in better detail later on.
Municipal CompostingSome towns and cities have begun programs to make compost on a massive scale. Food, paper, and yard waste are collected from homes and restaurants, and hauled to a large field. The material is sorted, shredded, and arranged in long rows, called windrows. Each windrow is ten feet high and hundreds of feet long. Industrial fans and ducts blow air through the material to improve oxygen flow. In some cases, windrows are covered with a plastic sheet to contain moisture and reduce odors. Specialized tractors turn the material periodically.
A chemist monitors temperature, moisture level, and other indicators to ensure safe and effective composting. Temperatures inside are so hot that they actually sterilize the compost and render even meat, fish, and dairy products safe for handling. The finished product is often very valuable, and can be sold to the agricultural industry to offset the cost of running the facility. Making composting is very cost effective when compared to landfills.
Windrow composting has drawbacks, namely storing, collecting, hauling, and processing of all that rotting kitchen compost material. Rats, raccoons, flies, fluid dripping, and odors can be hazardous at collection points as well as on route to the composting facility. In most cases, an additional fleet of diesel trucks, with all their dirty emissions, is required. The air ducts and plastic covers are usually discarded after just one or two uses, thus contributing to landfills. Initial startup expenses can be prohibitive.
In-vessel systemsFor years, hotels, schools, food processing plants, prisons, and other large institutions have used industrial machines to make compost and reduce waste hauling fees. The machines are essentially big tanks with lots of heavy duty mixing and pumping equipment. The compost is fully contained, such that fluid drippings, flies, and odors are eliminated or otherwise disposed of. High temperatures can be reached quickly and reliably to render meat, fish, and dairy products safe for handling.
But there is a downside. The investment is typically tens of thousands of dollars, and requires a great deal of space with special sewer and electrical hookups. A dedicated, trained, and experienced staff must operate and maintain the equipment. Depending on location, odors can be a problem.
Worm compostingAnother approach is to let worms eat your trash, in a process called "vermi-composting." Worms will eat almost any kitchen compost, produce little odor, take up little space, and they work fast. A variety of inexpensive or home made bins contain the worms and wastes such that you can add more waste and remove the finished product in a convenient way.
The disadvantages of worm composting are many. The worms don't sterilize the material with high temperature, so meat, fish, and dairy products are not safe for worm composting, and germination of seeds may occur. Some people encounter smells and excessive fluid drippings, depending on the type of kitchen compost used. And of course, there is always the fear of worms getting loose—whether from the quest for more food, or inadvertent encounters with children or pets. For some, the very idea of squirmy little critters is simply not acceptable.
NatureMill—a home solutionNatureMill brings home composting to the mainstream user. It is essentially a miniature in-vessel kitchen composting system. NatureMill delivers an answer to the problem of space and labor for both traditional composting. It is a great upgrade from an ordinary compost tumbler or worm compost bin. Waste is collected right where it is generated—in the kitchen. A computer controls the temperature, air flow, moisture, and mixing to accelerate the process and eliminate the backbreaking work. Everything is fully self contained in a modern, attractive container. Just a few square feet of floor space is required. No special plumbing or electrical connections are needed, other than a standard electrical outlet. There is no need to handle and transport the rotting material.
Best of all, NatureMill provides home gardeners with a source of rich, organic compost. And there is something uniquely satisfying about witnessing the entire food chain: from the garden, to the dining table, and back to the garden again.
A San Francisco Start
NatureMill inventor Russ Cohn is not easily impressed. Back in 2002, his home town of San Francisco started collecting food scraps for composting, in addition to collecting bottles and cans for recycling. 'Now that really makes sense,' he thought as he eagerly tossed his food scraps into the shiny new green bin provided by the city. Less landfill trash means less global warming. Way to go San Francisco!
Unfortunately, it wasn't so easy. Within a few weeks, the green bins up and down his block became grimy and insect infested. A raccoon family moved into the neighborhood. Trash day became even more unpleasant than usual - especially on a warm day. Soon compost collection became mandatory for all buildings in San Francisco, with "trash police" handing out steep fines to those don't comply.
A Chance DiscoveryThen a funny thing happened. Russ went on vacation and forgot to empty hia kitchen compost bucket. A nasty surprise awaited his return: an unbearable smell, fruit flies, and a very unpleasant clean-up job.
Grudgingly cleaning the bucket, he noticed it was warm - evidence that microorganisms were hard at work. The composting process had already begun right in kitchen bucket! Just a little more oxygen, some mixing, insulation, and a filter could make the process clean and reliable. As an MIT graduate and garage tinkerer, it wasn't long until he got to work building a better composter. Dozens of patents and prototypes, the NatureMill home compost machine was born. Within months the product took off and was picked up by Home Depot and Amazon. The rest is history....
We're up to great things. Just watch us. Someday everyone in the world will make compost, and what a difference that will make.
