For those who take being green to the next level BluePlanetSMART – a spherical, weather-resistant blue plastic composter – takes the smell out of indoor composting.

This cool looking, stylish device by Ecolosphere Inc accelerates the decomposition rate and easily rotates for aeration. The BluePlanetSMART cuts the volume of a household garbage bag by more than a third, producing high-quality fertilizer for flower and veggie gardens, lawns and houseplants. The tumbler holds 9 cf and the base stores 5 US gallons of compost liquid which is great for watering. It’s available online at Costco.com for $239.99.

The BluePlanetSMART’s round shape gives it a surface/volume ratio that is smaller than for any other shape. The smaller the ratio, the less the impact of heat loss on the total heat generated and the faster the decomposition.
