We’re trying our best to not mention composting toilets in this particular top 5 (they’re so great, it’s hard not to), so let’s move along quickly, shall we?

Next up, the Bokashi Kitchen Composter, a year-round compost system that can be used indoors without the fear of odour issues. This Japanese-designed system is particularly useful for apartment and condo dwellers that don’t have yard or porch space for full-sized composters.

Using the patented Bokashi method of beneficial microbial innoculation, the BKC anerobically ferments and pickles your food and table scraps in less than half the time of conventional compost bins. The air-tight lid ensures the proper environment for the fermentation process to occur.
