Environmental Sediment Treatment


E.S.T.’s mission Provide an environmental and sustainable solution for preventive and curative treatment of siltation problems with-and eco-innovative silt removal process. This nature-based solution is an economic and ecological alternative to current practices for removing, pretreating and especially recovering the sediment. By integrating environmental and economic challenges, E.S.T. enables the development and supply of recovery industries related to sediments worldwide (agricultural, construction, etc.). Solving all problems of siltation (dams performance, flooding, pollution, navigation on waterways ...), E.S.T De-silting Robot is a versatile machine which, with its development, will solve many other problems associated with the aquatic world: aquaculture waste, the fight against invasive plants, eutrophication, cyanobacteria ...

E.S.T. eco-innovative process demonstrates the viability of cost-effective, environmentally sound and safe recovery of sediment to unlock a substantial volume of unexploited secondary raw materials thanks to its systemic approach aiming at removing, pre-treating and conditioning sediment simultaneously and get them ready for industrial symbiosis in agriculture, construction and building industries, etc. and enhance EU security supply. E.S.T silt removal process consists of 3 automated machines: De-silting Robot (floating and underwater) offering 2 optional specific treatments against cyanobacteria and invasive plant species, and 2 other features, on the river bank, the sludge pre-treatment facility and the nutrients conditioning machine. Not only it is more environmentally-friendly but it also has the added value of enabling the circular management of removed sediments 100% and to prevent from pollution remobilization. This is an advantage in the case of polluted sediment in comparison with what the dipper arm of a backhoe can do.
