What do you do with your dog or cat poop? Toss it in the garbage? Put it in your compost heap? Hurl it at your noisy neighbors? Well, according to Seattle researcher Lawrence Green, you shouldn’t be doing any of those things. Feces can contain wonderful things like toxoplasma parasites, E. coli, and salmonella bacteria, which can get into the groundwater. In plastic bags in landfills, it generates methane gas and attracts vermin. To that end, Green developed a product called the BokashiPetCycle Fermenting System. It allows you to pickle your pet’s poop, turning it into a harmless plant fertilizer.
