There is a 3D-printed public toilet in Sun Mountain National Forest Park, Suzhou ,Jiangsu Province, China. The green-and-wood-colored toilet has been named"little box in forest.” It covers 20 square meters. It was made from garbage using 3D.printing technology .The eco-friendly (環(huán)保)toilet was built without any metal, but it's even stronger than those built from concrete material(水泥材料)

As part of China's “toilet revolution (革命)”, the government tries to improve public toilets. Suzhou has been using the top technology in its toilet building.

At some tourist areas, tourists can scan QR codes(掃碼)with their mobile phones in order to receive 80cm toilet paper. They can scan the codes many times for more paper, but have to pay if they scan too many times. The invention can prevent toilet paper waste. The technology can help save nearly 9, 000 yuan per toilet every year.

Suzhou is also using big data( 數(shù)據(jù))technology to manage public toilets. An online service platform (平臺) has been set up for toilets in tourist areas.
