To prevent that the plastics we retrieve, eventually end up as litter again, a good reuse or recycling is needed. Together with our international partners, we share the purpose of creating a circular economy.
Recycling floating debris is still in need of further intensification and innovation. We are exploring the further potential of recycling plastic litter into different kinds of valuable products.

Recycled Park

Floating parks are a plus for cities. They bring more greenery to highly urbanized areas. 

In collaboration with the Municipality of Rotterdam, we developed green structures from recycled plastics. In this way, we can stimulate biodiversity in harbors.

We constructed hexagon shaped building blocks where on, at and in vegetation grows. Through the park runs a small canal about half a meter deep, where birds, fish and micro-organism find food, breeding ground and shelter. 28 hexagon blocks of 5 square meters make our Floating Park in Rotterdam 140 square meters. It is located in the Rijnhaven, Tillemakade 99, and open for visitors.

Litter Traps

We developed passive Litter Traps to retrieve floating plastic in ports, rivers and harbors, before it enters seas and oceans. The Litter Traps effectively retrieve marine litter without using any energy. We’re currently developing more versions of the Litter Traps; traps with a larger capacity for the marine litter, in order to be emptied less frequently, and a modular Litter Trap that can easily be transported globally, for the worldwide approach to prevent floating plastics from entering seas and oceans.

Seating Elements

To raise awareness about the damages caused by plastic pollution, and to show the valuable possibilities of recycling plastic waste, we produced 3D-printed sofas from the plastic litter we retrieve. The sofas are available for sale and the size is adjustable on request.

Durable building blocks

In most of the areas where plastic pollution is highly concentrated also the housing situation is poor. People live in slums and have a high demand for durable shelter. The bricks can be used as building blocks to make many modular and circular designs. Each brick is made of 1.5 kilos of 100% recycled plastic with dimensions of 200x100x135mm (LxBxH).Recycling plastic litter into housing turns the environmental problem into a benefit for the local population. It shows the potential and value of circular re-use.
