Maacq Oase

A cycle of elements: recovering nature with residual flows


Maacq Oase



A circular solution to nitrogen deposition.

In Maacq Oase, the residual flows from humans are returned to nature with 3D-printed sculptures that slowly dissolve by natural erosion, offering a circular solution to counter the effects of nitrogen deposition in nature. Maacq Oase is a collaboration of Fillip Studios and Omlab, a circular and bio-based design studio.

Maacq Oase is made of materials that are extracted from water purification plants and are usually incinerated. Out of these waste materials, Omlab developed a 3D-printable paste with calcite as its main ingredient — and a 3D printer to process it.

3D-printable paste made as solution to nitrogen deposition

Through design research, Fillip Studios developed 3D-printable sculptures that — once placed in nature — slowly dissolve and release calcium into the ground, reducing nitrogen acidification. In addition, different types of seeds are added to the layers to increase biodiversity.

Maacq Oase gives nature a chance to recover.

Fillip Studio’s designs visually emphasize the multiple layers of the project. Layers with different colours and organic shapes are reminiscent of natural soil erosion, while geometric shapes remind us of human influence on nature. With Maacq Oase, Fillip Studios and Omlab give people the opportunity to use this influence in a positive way.

Due to erosion by wind and rain, the object will eventually be completely absorbed into nature.


Maacq Oase was presented at Dutch Design Week 2021 in the exhibition It’s In Our Nature. The set-up represents a timeline in which the 3D-printed sculpture dissolves into nature and simultaneously improves local biodiversity.

Maacq Oase is a collaboration with Omlab, who developed the material with AquaMinerals B.V., Energie- & Grondstoffenfabriek and Kaumera.

Materials supplied by AquaMinerals B.V. (calcite), Kaumera (Kaumera Nereda® Gum) and Recell® (recell-cellulose).

We are searching for companies to collaborate with on the applications of our research.
