Besides the 'independents', there were many other organisations involved in the cleanup of the entire Chek Jawa stretch, including AVA, LTA, St Nicholas Sec. School, Pei Hwa Sec. School, Advantest and Gemalto.

According to the data collected at Chek Jawa on 12 Sep 2009, there were 325 people involved in the event and they collected 2.786 tonnes of trash. That is about 8.5 kilogram of trash collected by each person!
The International Coastal Cleanup, Singapore, is now in its 18th year of battling marine trash in Singapore. A big part of the cleanup is actually about the collection of data about the trash itself. By collating data, scientists, government agencies, corporations and NGOs gain a better idea of what constitute our trash and what harm the coastal environment, and hopefully formulate better laws and strategies to fight marine pollution.
