“…Harbor dredged sediment were once used to fire clay bricks and their mechanical properties increased by 33% when sediments were added with 20 wt% and fired at 850 °C [ 151 ]. At the replacement level of 10–30% river sediment, 1–2% sewage sludge, and 1% wheat straw for shale, bricks with low thermal conductivity, light weight, and high strength were successfully manufactured in line with local standards [ 152 ]. Furthermore, as early as 1903, ready-mixed concrete was first produced in Germany, in which dredged sediments were applied as a fine or coarse aggregate in construction production.…”

Sediment is an important part of aquatic systems, which plays a vital role in transporting and storing metals. Due to its abundance, persistence, and environmental toxicity, heavy metal pollution has always been one of the hot spots in the world. In this article, the state-of-art ex situ remediation technology for metal-contaminated sediments is elaborated, including sediment washing, electrokinetic remediation (EKR), chemical extraction, biological treatment, as well as encapsulating pollutants by adding some stabilized/solidified materials. Furthermore, the progress of sustainable resource utilization methods, such as ecosystem restoration, construction materials (e.g., materials fill materials, partition blocks, and paving blocks), and agriculture use are reviewed in detail. Finally, the pros and cons of each technique are summarized. This information will provide the scientific basis for selecting the appropriate remediation technology in a particular scenario.

“…For a cement production system, ingredient substitutions have also been studied by many scholars. For example, the river sediment has been selected and considered as the primary raw material for building materials [52]. Dredged sediment as a raw material was reused for Portland cement production [53].…”

As one of the highest energy and resource consumption industries in China, discussion on the sustainability of the cement production system has great significance. This study conducted sustainable calculations and analyses for cement production systems based on the emergy method. This study also considers the sustainability impact of clean energy on the overall cement production system. Through a series of sustainable indicator measurements, the results prove that: (1) the two primary sections, non-renewable resource and non-renewable energy, contribute 88.6% and 11.1% of the emergy proportion, respectively; (2) the emergy sustainability indicator (ESI) was only 0.058, which is significantly less than the standard; (3) through the analysis of eight hypotheses, a very small change between the absolute values was found, which demonstrates that the sensitivity changes are within acceptable limits for the cement production system; and (4) by integrating the biological power generation subsystem, sustainability has been optimized in the cement production system. Finally, two ameliorated strategies are discussed in this paper for the better sustainability performance of the cement production system in the future.
