Indoor Composting for Urban Eco-Warriors

There’s no doubt that composting is an excellent way to recycle leftover vegetable and food waste. However, if you don’t have a garden, composting is a little more difficult. Thanks to a novel indoor composter by Nature Mill, urban eco-enthusiasts can compost their waste without the need for a garden!

The indoor composter works by mixing the waste and combining it with air flow, heat and moisture. The heating process kills odours, fungi and seed germination. The composter uses a special culture of bacteria to break down the organic matter into a nitrogen rich compost. The compost can then be used for indoor or outdoor plants as needed. You don’t have to use the composter indoors. As long as you keep the power supply dry, you can use it outdoors too, or perhaps even in your garage. A special carbon filter ensures odours are kept to a minimum. At it’s worst, the gadget produce a mild aroma similar to mushrooms or damp straw.

Since landfill waste sites are full of waste with virtually no airflow, landfill sites can be a source of large quantities of methane emissions. Methane is a gas that contributes to the global warming effect, and is typically released when bacteria breakdown organic matter without the presence of oxygen. Since the composter gadget draws oxygen into the composter, there are no methane emissions! The best bit is that the unit draws only 5 kwh of power a month, it costs less than $1 a month to operate! It uses less energy compared to what would be needed for a rubbish truck to haul away the rubbish. The Nature Mill indoor composter is better for the environment in pretty much every possible way!

(Editors note)

Nature Mill is available online, or in-store at Home Depot in Canada and Target in United States. Nature Mill also has a great video on indoor composting that is perfect to share with your roommates or partners who might be hesitant to compost indoors.

TIP: For those who live in a condo or apartment and don’t have access to a garden, you can always put the compost in your house plants. For those who live with snow during the winter,  store the compost in a garbage bag until spring then distribute it to neighbours with gardens or the plants outside.

  1. I personally love the smell of my compost. When you take care of it it smells natural and fresh. Love the indoor idea. Now no one has an excuse not to compost. I have near to no garbage to take out as everything is either recycled or composted. Thanks for info!

  2. Hey Deana. Thanks for visiting. I can’t wait to start composting. I want this for xmas. I’d say 75% of my garbage, if not more, is food. And did you know that 25% of the world’s greenhouse gas comes from the decomposition of food in landfills? Imagine if everyone composted. Take care!

  3. I am surprised there is so little commentary on this Nature Mills composter in the Internet. Let me give you my experience. The composter was sent to me defective. I had to fix it by cutting away styrofoam (yes, the picture makes it look like it’s plastic, but it’s made from styrofoam) so the trapdoor where the finished compost falls down into a tray would open. I made about 4 batches of compost before the steel latches which the mixing arm pushes against worked their way into the styrofoam walls, again making the trapdoor not open. This is clearly a design flaw, that Nature Mills was prepared for, because they gladly sent me an “upgrade” kit which consisted of two steel plates to put between the styrofoam wall and the latches. This kit was very difficult to install and the instructions were poor. I don’t think the units should be sent out without this important fix. The compost? A great deal of water is generated during the composting process. This water flowsinto the trays and out the front door of the unit. The tray that the unit stands in is laughably small and soon overflows with brown water. The instructions suggest adding more brown material and baking soda to make the compost less wet. Their suggestion to add less “green” material defeats the purpose of having a kitchen composter, where most food waste is of the wet fruit and vegetable variety. Our composter unit is far too leaky and has been banished to an outside supply room where I bring it kitchen scraps collected in a plastic box. I use sawdust for brown material which I got for free at a sawmill. Don’t forget the baking soda. My final rating? “A” for idea, “D” for quality control. The bright side, composting has reduced my weekly garbage by one half.
