Today Chinese scientists have claimed victory in their battle to improve public restrooms, introducing a bacterial spray that can almost get rid of all the bad smell. First, a set of six types of bacteria work to break down the smelly compounds and then a perfume made from orange skin lightly scents (使芳香) the air. The “smellfree toilet” study from the Chinese Academy of Science was declared the “ultimate” cure to an_“urgent”_national_issue.
“Five scientists have worked on this from 2011
to the beginning of this year,” said Dr. Yan Zhiying, a bacteriologist with the academy's Chengdu Institute of Biology, adding that they had spent £140,000 on the project.
“Some local government officials here visited a sewage (污水) plant and saw that the treatment technology had come from Japan. They wanted a homegrown solution so they asked us to work on it,” he added. “We obtained bacteria from all types of waste from humans, pigs, chicken and ducks, and we tested our compounds one by one,” he said.
“The smells coming out of public toilets, or trash cans, are made up of more than 160 different compounds,” he explained, adding that their bacteria spray can change and absorb many of them.
He boasted that the Chinese formula (配方), which costs only around £5 per liter, has no side effects and can be used to remove any bad smell.
