Our solutions

We aim to restore and protect water quality by absorbing pollutants and nutrients from freshwater entities using phytoremediation, a purification process where plants remove, absorb and allocate contaminants from the water. Inspired by comprehensive scientific research on wetlands we have developed and implemented our version of an environmentally friendly and ecological floating treatment wetland. ECO Island’s ECO Filters are biomimetic, imitating the systems of natural wetlands and supporting a natural restoration of the environment. The technique behind floating treatment wetlands is unique, as unlike traditional water cleaning systems and filters, it requires no chemicals, no physical filters and no energy supply.


Our ECO Filters are biomimetic designed floating islands also known as floating treatment wetlands. Specially for our human made islands are, that they are all made as scalable and modular elements, making us able to customize every island in shape, size and plant species to meet the challenges our costumers might have. The combination of plants selected for the floating treatment wetlands are tailored to have the most efficient removal capacity while at the same time being local plants, that will increase biodiversity in the local and existing ecosystems. The wetlands are designed to be climate resilient easily adjusting to changing water.

An ECO Filter consists of a floating mattress, a sustainable growth media and a natural biofilter, all parts designed to encourage plant remediation and secure a strong microbial activity. The chosen materials enhance the management and removal of nutrients (such as phosphorus, nitrogen, ammonia etc.) heavy metals and total suspended solids from the freshwater.

The floating treatment wetland allows aquatic emergent plants to spread their roots directly into the water. As the plants on floating treatment wetlands grow with attached biofilm, the bio-available nutrients in the water are absorbed by the roots and stored in the plant tissue (biomass) securing an effective and low cost phytoremediation. Periodic harvesting of the mature plants prevents the sequestered nutrients from reentering the water when the plants die and decompose.

ECO Filter use a patented floating wetland system, while the system allows for easy harvesting and replanting to optimize nutrient removal.

By installing our ECO Filters you can minimize water pollution, improve the environment as well as avoid loss of biodiversity by establishing new habitats.

Thanks to our technology we are able to monitor and detect the different levels in water quality and adjust the floating treatment wetlands to the challenges so we can secure you the most efficient uptake of undesired substances.


ECO Habitats are floating wetlands designed to increase biodiversity as they function as diverse habitats for pollinators, wildlife and fish. The wetlands can be seen as floating ecosystems and we design them to establish ideal habitats for the local wildlife. The wetlands are covered with carefully selected plants in order to provide shelter, nurturing and resting areas for birds, pollinators and fish.  Underneath the floating wetlands the submerged roots provide excellent feeding grounds for fish and invertebrates and at the same time provide shelter for the smaller fish. To attract bees, butterflies and other pollinators it is important to have some flowering plants as well. The pollinators play a very important role in the ecosystems and the survival of many species depend on the pollinators. 

ECO Habitat is a way to restore ecological function and healthy biological activity while mimic the function of natural ecosystems among others in urban areas. The ECO Habitat wetlands also improve water quality and restoration, but the nutrient uptake might be a bit smaller, since the plants are primarily selected to improve healthy ecosystems and increase local biodiversity.
