Commuters in Osaka reduce their environmental pee-print
Because we never can seem to get enough bathroom humor -- and the fact that the Nanakai Electric Railway in Osaka, Japan is saving 22,000 metric tons of water this year with its 73 new waterless urinals -- it looks like the water-free toilet movement really does have something to go on. Wait, that came out wrong. Research conducted by UCLA supports the idea that waterfree urinals might bee a good way to combat future water shortages.Composting toilets and chem-urinals have long been a badge of honor for serious environmentalists and conservationists, but only recently have waterless urinals broken into the mainstream. These waterless urinals use a replaceable cartridge which uses an oil-based liquid to filter urine and trap odors, sending the filtered urine back into the normal waste stream. According to UCLA's study, along with saving water and the CO2 created by water treatment, microbial growth rates are no greater with waterfree urinals than with the normal flush type.
