E.S.T. - Dredging robotic system

An environmental and economic dredging solution to help recycle sediment from lake and river beds

A system of three robots to extract and prepare non-polluted sediments to be recycled directly on-site - including drying and conditioning them - thereby facilitating transport and reducing fuel costs.

Sediment siltation problems are inevitable and when extracted, sediment is almost never recycled. Mud needs to be extracted when it begins to take up too much space in a lake or river, preventing transport, or when it blocks a dam. This solution is comprised of three robots operating 24 hour a day; the 1st slowly extracts the mud, before passing it through a tube to the second and third robots which treat and package the sediments. Because of its size and adaptability, the E.S.T. can be transported anywhere there is a silting, dredging or sediment issue.

Key features for a positive impact on quality of life

  • Preparation and valorization of recovered sediments
  • Very energy efficient
  • Effectively combat the devastating effects of floods
  • No remobilization during extraction


  • A reduction of 77.7% of fuel demands compared to the actual method for a 17,000m3 area
  • At least 20% cheaper than current solutions
