Whiff of success in toilet odor killer

Chinese researchers are close to sniffing out a noxious social problem: smelly public toilets.

The new technology is still undergoing trials, but already, the Chinese Academy of Sciences is touting it as the ultimate odor killer.

It’s a triumph of science and economics. Although it won’t leave public lavatories smelling roses, it will kill up to 75 percent of the overpowering stench in an environmentally friendly and cost-effective way, according to the New York Times.

The science behind the discovery is a special mixture of bacteria and the essence of tangerines. The prepared mixture, which comes in liquid or powder form, feeds on human waste when applied, precluding the growth of odor-causing organisms.       

Unlike chemical solutions, which are expensive and can be harmful to the environment, the new biotreatment is ideal for non-flushing toilets often found in public areas.

Large-scale experiments are being planned in the Huanglong Nature Preserve and Jiuzhaigou National Park, both popular tourist destinations in Sichuan province.

Tourists and local visitors are the main beneficiaries of the initiative. Any good word they put in about China’s public toilets of the future would be a whiff of success for Chinese scientists.
