![]() ![]() Reactive silicate minerals participate in natural carbon sequestration Using different grades of sediment dredged from Europe’s largest sea port – Port of Rotterdam, the project will test the feasibility of transforming harbour sediment into a building material with neutral or negative CO2 footprint. Dredged sediment a potential building materialĭredged sediment is a potential building material but must be modified to prevent negative environmental impacts. This makes dredging costly, but this could be avoidable if the sediment became a resource. ![]() The sediment is currently either transported out to sea or contained due to high levels of toxic compounds and heavy metals. ![]() Oxidation of dredged sediment leads to CO2 emissions and the release of contaminants. The team will investigate this in collaboration with the Port of Rotterdam, Royal IHC, Van Oord, NETICS, Wetsus and TNO.Įach year millions of tonnes of sediment are dredged worldwide as part of harbour maintenance. Photo: Nico LooijenĪ team of researchers from Utrecht University and NIOZ have won a grant from the NWO Topsector Water & Maritiem to investigate the potential of dredged harbour sediment as a carbon neutral resource for building materials. Using sediment dredged from the Port of Rotterdam, the project will test the feasibility of transforming harbour sediment into a building material with neutral or negative CO2 footprint. ![]()
