Particle material (silt, clay and sand proportions of 62 %–79 %, 14 %–20 %, 7 %–17 %, respectively) and had a medium–high level of nitrogen The sediments mainly comprised small size High amounts of nitrogen (170–450 µg L −1), leading toĮutrophication problems. Uncover possible sediment recovery paths and define the baseline ofĬontamination in the water body. This study focuses onĬharacterizing the sediments, pore water and surface water from the bay to Is required to recuperate the water level. Shallow semi-enclosed bay located in Kalmar, Sweden. Therefore, the first step is to analyseĪnd identify the sediment composition and properties. Nevertheless, the recovery varies on a case-by-case basis andĭepends on the sediment components. Recovery of valuables represents a way to eliminate dumpingĪnd contributes towards the sustainable extraction of secondary raw Theseĭisposal methods are not in line with circular-economy goals andĪdditionally are unsuitable due to their legal and environmentalĬompatibility. Removed material is commonly disposed of in open oceans or landfills. Guarantee the navigation levels or remediate the aquatic ecosystem. Ports and bays need to extract the sediments to Millions of tons of bottom sediments are dredged annuallyĪll over the world.
