Bacteria that feast on garbage may provide an environmentally benign way to dispose household waste, say British engineers who are testing a new anaerobic digester -- that does not require air -- for treating dustbin waste.

The bacteria, which are anaerobic, break down the organic portion of household waste and produce methane in the process. This gas can be used to provide electricity, say reseachers from Motherwell Bridge Envirotec., one of the 3 organisations involved.
