Building blocks from the Weerribben

BioBblocks B.V. / BioBlocks

The Weerribben is a famous nature reserve that was created centuries ago by man himself by peat excavation. Nowadays, the unique flora and fauna are again maintained by humans: sods of organic residual material are removed to prevent the swamp from growing over. These sods are processed into sustainable building blocks in which the assimilated CO2 is stored.

Made from

BioBlocks are building blocks of pressed and dried carrion and turf, developed by Voets Gewapende Grondconstructies in Den Dungen.

Production process

De Weerribben is a 3,500 ha nature reserve in the northwest of the province of Overijssel. When the area is managed, so-called kragge (sphagnum moss mats), tuf and cuttings are released. In the past, this had to be removed or stored. Voets Reinforced Ground Structures in Den Dungen found another application for this: Bioblocks. The blocks are created by pressing and drying the turf and turf into building blocks.


Earth-retaining structures in infrastructure, noise barriers, bank protection, garden and park design, etc. Possibilities are also being investigated and further elaborated in residential and non-residential construction.

Environmental impact

In addition to the fact that BioBlocks are made from plant residues and thus make a positive contribution to the environment, the blocks are also recyclable after demolition. Under certain circumstances they are even biodegradeble (naturally degradable) and can therefore be returned to the factory for reuse (cradle to cradle).
