It is sad to hear that some places are having problems in disposing off their own wastes. That is the creation of the Gardiner CH4 by Virginia Gardiner is a total blessing to these places. The CH4 is a plumbing free toilet that turns human waste into a bio-fuel for sanitation strapped cities. With the CH4 plumbing free toilet, human wastes will be carried down to an odorless and sealed compartment and in every three to four days, it will transport to bio-digester and get some cooking fuel. This toilet will not only save water but will also lower down the energy usage for cooking.
