Crap into compost

Though they’re an old concept, composting toilets are getting lots of love recently on environmental blogs. One company in particular, Sun-Mar—which first released a composting toilet in the early ’70s—creates stylish and functional composting toilets for modern-day eco-friendly homes. Sun-Mar offers three types of johns: centralized flushing units, centralized dry systems, and self-contained toilets that don’t require plumbing or water (or much space). All three types are odorless, sanitary and provide heaps of free compost. Visit the company’s website to browse dozens of models and configurations that will all reduce your water bill.
