“…For example, Rugani et al (2011) found that, in the Italian city of Siena, aside from achieving better environmental outcomes than other contemporary management systems, conservation of its network of underground galleries was essential to the cultural heritage of the city. In addition, Studds and Miller (2010) proposed solutions for the reuse of dredged sediment materials to ensure the future viability of the waterway.…”

Sustainability has been progressively incorporated into all dimensions of society as a response to the negative externalities of the traditional production model, and the craft sector has been no stranger to this. Thus, the present work constitutes a bibliometric analysis of 894 research articles from the Scopus database on sustainable crafts in the 21st century, identifying the growth trends, published articles, and the most productive journals, authors, institutions, and countries. Additionally, we have identified the main research topics that have emerged in sustainable crafts in three time periods: before the international financial crisis, the post-crisis period, and, finally, within the 2030 Agenda and the Sustainable Development Goals set out by the United Nations (UN). Based on the bibliometric indicators analysed, we conclude that this research area has grown exponentially, particularly in response to the Sustainable Development Goals, increasing the abundance and diversity of the issues investigated.

“…Research into this field has focused on recycling dredged sediment as a secondary raw material in different applications as a way to preserve non-renewable resources and reduce the environmental impacts of off-site marine disposal [53]. Although the material obtained from dredged sediment is non-renewable, it has several characteristics and advantages in terms of sustainability [59]. Firstly, the quantities generated by dredging operations are immense and present a significant resource to fill the need for construction materials [60].…”

“…It allows for both a sustainable dredging disposal mechanism and the promotion of a waste-to-wealth approach [56,[64][65][66][67][68]. A number of studies have identified paths to valorize dredged material in the construction industry [59,69,70]. Dredged sediment can be used as an alternative source of conventional aggregate used for the manufacture of concrete or mortar [24,60,[71][72][73][74] by acting as a substitute for sand.…”

Characterizing Harbor Dredged Sediment for Sustainable Reuse as Construction Material

et al. 2023

An unprecedented rate of construction has profoundly increased the risk of scarcity of natural resources and threatened ecosystem sustainability. To establish an effective sustainable development policy, it is imperative to promote the use of responsible production channels, including waste recycling. Reuse of harbor dredged sediment is commonly investigated as a valuable alternative to non-renewable natural resources needed for construction. Sediment characterization is decisive in the valorization process, aiming to identify potential recycling paths. Existing research efforts, however, have rarely investigated case studies in developing countries. Moreover, they have tended to focus on the technical aspects, ignoring economic feasibility, which carries important implications. This paper fills this gap first by meticulously selecting laboratory tests for characterization within the means available in developing countries and second by conducting a cost-benefit analysis. The port of Safi, Morocco, was chosen for the implementation of the adopted approach. Results showed that dredged sediment is a sand readily reusable as a construction aggregate. Several applications are possible, the most interesting one being concrete works, as a substitute for conventional sand. While treatment by washing and dehydrating proved necessary, cost-benefit analysis confirmed the profitability of recycling. Hence, beneficial reuse of dredged sediment as construction material is technically and economically feasible.

“…Thus, reservoir bottom sediment dredging is performed periodically to remove thick sediments for maintenance purposes. However, the removal and disposal of dredged sediments requires considerable space as landfills and energy consumption during the dredging operations [6]. A primary factor that makes the concept of reusing the sediments a feasible solution is the potential economic benefits by cost-cutting of disposal and environmental issues related to the depletion of natural resources.…”

“…A primary factor that makes the concept of reusing the sediments a feasible solution is the potential economic benefits by cost-cutting of disposal and environmental issues related to the depletion of natural resources. In relation to this, an approach to determine the embodied energy and carbon dioxide contribution of ground improvement works has been developed [6,7]. Dredged sediments are often polluted with contaminants, such as heavy metals [8][9][10].…”

Use of Reservoir Sediments to Improve Engineering Properties of Dune Sand in Oman

et al. 2021

Managing sediments dredged from reservoirs of recharge dams is an environmental issue, however, these sediments can be an abundant and economical source of fine-grained fill soil. This experimental investigation quantifies the geotechnical properties of a reservoir sediment used to improve engineering properties of a poorly graded dune sand in Oman. The binary mixes were prepared with different percentages (5, 10, 20, 50, 75, 90, 95%) of sediment with sand. Laboratory tests such as gradation, consistency limits, compaction, and unconfined compression tests were performed to measure the engineering characteristics of the binary mixtures. The results showed that the maximum dry density increases up to a sediment content of 50% and then decreases with further increase in the sediment content. The optimum water content increases with the increase in sediment content from 17% for pure sand to 22.5% for pure sediment. The optimum moisture content shows a good correlation with the plastic limit of the binary mixture of sand and sediment. The unconfined compressive strength substantially increases with sediment content up to 75% and then decreases with further increase in the sediment content. The binary mixture of sand sediment is sensitive to moisture, however, the order of strength stability against moisture is dune sand mixed with 75, 50, and 20% sediments. The addition of sediment to dune sand improved the uniformity coefficient to some extent with an increase in the maximum and minimum void ratios as well. The elemental analysis of the sediment confirms that the material is non-contaminated and can be employed in geotechnical engineering applications as a sustainable and environmentally friendly solution.
