The European dredging industry generates an estimated 200 million cubic metres of sediment annually. Approximately 5 million cubic metres of dredged material is extracted from the port basins of Rotterdam's port area each year. The majority of this material comprises a mixture of very fine sediments and water. Converting this sludgy mix into soil typically requires a considerable amount of time for the water to naturally drain or evaporate, a process known as dewatering.

Soil dried by worms

Miguel de Lucas, CEO of Medeina, discovered a method to significantly accelerate the dewatering process. This approach combines biology and physics in an unconventional way, with a starring role played by worms. According to Miguel de Lucas, ‘When our worms are introduced into sediment with water, they create a network of tunnels all through the sediment. This significantly accelerates the drainage of water.’
