INDIA: Konkan Railway has begun equipping its stations with 'bio-toilets' which used anaerobic biodigester technology developed by the Defence Research & Development Organisation for use in remote areas.
The railway said the maintenance-free toilets can be installed in two days rather than the two months needed for standard toilets which require a sewer or septic tank, and are 70% cheaper at Rs30 000.
The bacterial breakdown of waste produces gas which can be utilised as fuel and clean odourless water which can be extracted for irrigation.
