Here's an interesting new form of product vetting from respected green web retailer/lifestyle company/yoga mat peddler, Gaiam: a heated Compost-Off where two composters (there was initially four in the running) are tested in the Gaiam gardens to see which has the most functional, easy-to-use design and performs the best. The illustrious champion will be added to Gaiam's already healthy roster of composters available for sale. The two decomposition devices duking it out are the Bio-Orb and the Earthmaker.

In the below video, Gaiam's brightly gloved judges, Jessica and Nicole, assess which composter has the leading edge. The parched, slow-acting Earthmaker's composting prowess seems to disappoint while the plenty-wet Bio-Orb is working so well that it nearly makes Nicole vomit on the spot. If swarming flies and gagging are signs of a winning composter design, than it looks like the Bio-Orb has the leading edge. May the best composter win!
