Rendu Ocean Center is a local NGO that works to clean up Shanghai’s beaches. Started in 2007 by three leaders of a grassroots community group and registered as an NGO in 2013, the organisation holds monthly clean-ups at Nanhui beach and other coastal areas near the city, gathering up to 300 volunteers for each outing. Much of the waste found on Shanghai’s oceanfront consists of plastic bags and styrofoam packaging. Rendu believes that educating people to separate waste, as well as collecting it, is crucial in learning how to prevent it in the first place and they therefore carry out a number of educational activities as well.
