Biodegradable 3D-structure for ecosystem restoration – Made from potato waste

BESE-Elements (Biodegradable EcoSystem Engineering Elements)

For the restoration of ecosystems, for example mussel beds, artificial structures are needed as starting points. To find an environmental friendly structure, Rodenburg Polymers, ENEXIO Water Technologies and Bureau Waardenburg partnered and developed the three-dimensional solid grid, the BESE-Elements.

Features of BESE-Elements

BESE-Elements are made from starch from potato waste and degrade under environmental influences without composting agents or special temperatures:

  • Environmental-friendly and sustainable material
  • Side stream potato starch
  • Renewable raw materials
  • Carbon neutral, non-toxic product
  • Biodegradable and digestible

Why do we need ecosystem restoration?

Within the last decades, a great loss of ecosystems like wetlands, mangroves and coral reefs has occurred. It is acknowledged that they deliver valuable ecological services for water purification and storage, carbon sequestration and coastal defense.

How do BESE-Elements support the recovery of mussel beds?

At first BESE-Elements® present a temporary structure and protection for organisms to start growing. After a certain time, sufficient adult organisms have grown and built up a structure on their own for younger ones to settle on. During this process the BESE-Elements® break down and the organisms establish and enlarge their own structure. Currently BESE-Elements® are used to stimulate the recovery of natural mussel beds in the Wadden Sea. Further pilot projects include the growth of reed beds, coral reef restoration and water purification.
