Japan "oyster toilets" to go global (日本の牡蠣トイレが世界に広がる!?笑い）

Tokyo: Japan's toilet makers famed for their high-tech latrines, want to go global with a simple, waste saving design based on oysters, a manufacturer said on Friday.
The design removes pollutants and acidity by filtering waste-water through large tanks filled with oyster shells, a byproduct of the seafood industry in southern Hiroshima prefecture, the manufacturer said.
Oysters offer a natural waste-management system because their jagged shells give micro-organisms a large surface on which to live and decompose sewage, said the manager of the Eiwa Land Environment Company.
Treating on cubic metre of waste-water takes about 300 kg of oyster shells, he said, adding that "since Hiroshima produces so much waste in terms of oyster shells, we never run out of them."
The filtered water is recycled to flush the toilet, making it ideal for dry regions of Australia, China and the U.S., he said. The company started making the toilets more than a decade ago and has installed them in 500 locations throughout Japan-AFP (インド新聞ＴＨＥ　ＨＩＮＤＵ　３月１４日より）

日本のトイレレベルは最高な事は知っていたが、１０年も前からこんな事してるなんて、全く知りませんでした！　日本の技術や研究はやはり目を引くものがある。　ここインドでの５星ホテルのトイレは日本製（ＴＯＴＯ）を使っているところが多いが、やはりコストが高い！！　インドのトイレは水力が弱く完全に流れない事もあるので、隣に水の入ったバケツがあって、その中の水も利用して、綺麗に流します。時々紙を使えないトイレもまだまだあります（詰まるため）
