Manmade floating islands use recycled plastic from PET (Poly Ethylene Terephthalate) drink bottles. A floating Island is a buoyant mat, made up of layers of nonwoven plastic matrix bonded with an inert marine foam. It is then planted with vegetation and launched in water body for different useful applications.
Some interesting features of floating islands (image credit – Floating Island International) are:
- A new variant of constructed wetlands to act as concentrated wetlands with huge surface area for microbes to remove water pollutants like nitrates, phosphates, ammonia and heavy metals that come from industrial and residential waste.

- The plant roots hang below the floating wetland to take nutrients from water.
- Floating islands can be launched into any waterway either small or big like pond, lake, stream, effluent pond, lagoon, embayment, even the ocean.
- Supports flexible design to be built to any shape and size.
- Buoyancy can be varied.
- Can be free floating or can be anchored or tethered in place.
- Advantages
- purify water by natural process
- help to sustain habitat for fish and birdlife
- help to prevent algae growth
- beautifies the area

Thanks for posting this. We just moved into a home with a rather large pond in it and we were considering getting in filled in but decided to leave it. We really wanted to liven it up though and those floating islands look gorgeous!
These would help create remarkable backdrops for my photos. I really hope I could push through in doing these for our pond.
