Reconstruction of ports, including dredging, is intensifying all over the world. Dredging is used to dredge ports - a type of excavation that is carried out underwater or partially underwater. Dredging helps to maintain waterways and ports navigable. It is a complex process consisting of stirring, lifting, transporting and disposing of the dredged material. The material obtained by dredging may be disposed of in the vicinity of the port or transported to another location by barge or by pipes in the form of liquid suspension. The disposal of dredged material has a significant impact on the environment. For example, changes in shore morphology during dredging can affect local habitats, cause changes in water currents and waves that can affect navigation, cause changes in water quality, affect benthic fauna, and fish spawning and cause other changes whose longterm effects on the environment are not foreseeable.
The problem of the research: most of the dredged material obtained in the process of dredging in the world is included in the re-use of resources, creating land areas, restoring the coast affected by coastal erosion and elsewhere, at the same time, the dredged material obtained in the port of Liepaja is disposed at the sea spoil grounds. As dredged material in the port of Liepaja consists mainly of solid, firm clay, stones and sludge, it could be used as a raw material in various sectors of the economy. For example, during the last port dredging project, a total of 2.7 million m3 of dredged material was exhausted in the port of Liepaja, which was disposed of at the sea spoil grounds and which could be used as a resource in implementing the principles of the circular economy and without harming the environment [10].
