Semakau Island is an island man made by the indonesians.
at Semakau island they burn the rubbish off in the cleanest way possible. 90% of the rubbish is emmited into gas that is highly filterated into a gas that is cleaner than air. the remainder 10% of the gas is turned into ash and is placed on the island. The island has a big body of water that is seperate from the actual ocean so it wont effect the rest of the ocean. the ash blows around the island into the man made part of the ocean but it is not bad for the enviroment as it has coral reefs that are still growing and is showing no sign of death!
On the island there is also a fish farm. the island is incredibly clean, this includes clean toilets witch everyone knows most public toilets are nightmares!
