Trash Islands

Increasing ocean vitality vulnerability led SpaceKnow to investigate artificial islands across the globe where the impact of trash has severely affected the ecosystem. We tracked ship activity as well as the progression of urbanization. Landfills can be a central point for cities to export their trash, but as their population increases, cities will have to become more aware of the survival of the oceans. See how the activity of ships around artificial landfills is tracked and detected by SpaceKnow analytics.


Our analytics are capable of detecting the number of ships over a span of years, months, and days. SpaceKnow wants to help in the fight for our waters, which is why we looked at the increasing activity around the island known as “Trash Island” in the Maldives. The expanding artificial island serves as a landfill for trash. The increase of ship activity represents the amount of garbage brought and dumped on the island, as tons of garbage are sent to Thilafushi island every day.

Thilafushi island is 4 miles (7km) from the capital and used entirely as a garbage dump, serving the surrounding residential islands. Trash is brought to the island mainly by ship, which is one of the algorithms we used to detect activity on the island. As you can see ship activity has increased by almost forty times in the last sixteen years.

Semakau landfill is on the eastern side of Pulau Semakau, south of Singapore. It is Singapore’s primary landfill covering 3.5 km2 and surrounded by a 7km rock perimeter. We know cities are looking for ecological ways to get rid of their trash, so we can help you understand and visualize the expansion in activity for both urbanization and ships.

A view of the Central Breakwater Landfill, an artificial island constructed for central Tokyo’s waste and will support shipping containers in the future. The landfill is primarily used for rubbish collected from Tokyo and processes tons of garbage on a daily basis. The landfill is the last disposal repository for Tokyo’s waste. Some agree that it is the most convenient manner of trash disposal coming from a large metropolitan city. SpaceKnow is able to detect the number of ships over a span of time to understand trends in ship activity and provide our clients with a deeper knowledge of the impact of urbanization and the manner in which cities handle their waste.
