I've been a composter for many years. As a kid, I had a heap in the backyard. In LA, I had a ComposTumbler. Out at the beach, I have a barrel under the house. But there's never been a decent solution for Manhattan until now. The NatureMill is an indoor composter that uses continuous airflow and a powerful carbon filter (which lasts up to 5 years) to remove odors from the completely seale unit. It mixes continuously, so you can add food waste at any time, up to 120 lbs a month. Compost is ready every two weeks – Just open the door and remove the compost. NatureMill is heated to accellerate composting and achieve temperatures hot enough to process dairy, meat, fish — even pet waste. And it uses just 5W of energy — less energy than the fuel required to haul away the uncomposted food waste to a landfill, where it would produce methane instead of composting. It does require some effort: some waste, like banana peels and long stringy things need to be cut into small pieces to prevent jamming. And like any compost method, it requires a balance of green stuff like vegetable waste, and brown stuff, like leaves or shredded newspaper. Read the reviews on Amazon.com before committing to one. But if you're willing to do a little work, it's a perfect green solution for those of us in the concrete jungle. Find it at a local dealer, select Costco warehouses, or order online for $299-399.
