Smart technologies, equipment and solutions are taking the spotlight at the annual China Toilet Revolution Innovation Expo in Xuhui District, which coincides with World Toilet Day yesterday.

The three-day expo held at Shanghai Everbright Exhibition Center from yesterday exhibits a range of toilet-related epidemic prevention technology, odor-removal and air-purifying technology, face-recognition toilet paper dispensers, as well as public and household toilet equipment and innovative products.

In its sixth year, the industry event gathers about 100 companies in the field to display their products and technologies.

On the first day, 26 toilet project deals worth about 15 million yuan (US$2.29 million) in total were signed, according to the Shanghai Greenery and Public Sanitation Bureau.

Pandemic prevention and control technologies at public toilets are a highlight.

Foam disinfection technology which significantly reduces the survival time of viruses is on display. “The foam provides a natural cover on pollutants and odor, preventing them from escaping, and it also contains germicidal agents,” said exhibitor Tian Haoran.

The technology will be used at the Dongping National Forest Park in Chongming District, combining facilities that can turn waste and excrement into organic fertilizer, Tian said.
