Shanghai builds 32 new Huangpu cleaning ships
Shanghai has constructed 32 new cleaning ships to guarantee the 45-kilometer coastline of Huangpu River will be clean, while the first unmanned cleaning ship is still under development and testing, Shanghai Observer reported on Wednesday.
The 40-meter-long type among the 32 new ships is the largest and most advanced cleaning ship in China. It can clean up to 400 tons of garbage floating in the river every hour, which is 30 to 50 tons more than normal waste-removal vessels.
A 5-meter-long fishing device, equipped at the stern of each ship, can reach hidden places where large cleaning ships cannot enter. The garbage it collects will be sent back to the cleaning ship for storage and transportation.
An unmanned cleaning ship, the first of its kind in Shanghai, will be able to seek out and transport garbage automatically following specific routes in the future.
