Kitchen trash no match for new disposal's microbes

TOKYO -- Kitchen disposal units are rare in Japan, but industrial machinery maker Eiwa is hoping to change that with a contraption that promises no clogged plumbing and no mess.

Jun Sashida, Eiwa's vice president, shows off the Zero garbage disposal.

     The company based in Hamamatsu, Shizuoka Prefecture, about 210km southwest of Tokyo, is promoting the Zero, which shreds food into tiny pieces, then sends them into a drum. After they are spun around and devoured by microbes for a few hours, the only thing left of the day's table scraps is water and carbon dioxide.
