The accelerated deterioration of carbonate stone artifacts under climate change has long been an urgent issue. Inspired by biomineralization, we developed carboxymethyl chitosan-diammonium hydrogen phosphate (CD) composite and investigated the conservation effectiveness CD compared to diammonium (DAP) on limestone. morphologies microstructures were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR). consolidating was through a compressive strength test. protective ability assessed disintegration resistance test, acid attack salt freeze–thaw aging cycle SEM observations revealed that chitosan (CMCS) served as effective template, inducing in situ formation uniform continuous calcium coating both surface interior stone. tests indicated further enhanced improved cycles. Notably, amphiphilic polyelectrolyte, CMCS functioned pH buffer barrier against sodium sulfate salts, which attacks. Additionally, did not cause significant variations esthetic appearance or water vapor permeability. We then applied at actual cultural heritage site, successfully demonstrating feasibility application reversibility real-world setting. Based study's results, our approach provides new perspective for developing multifunctional sustainable materials artifacts.

Marine biological shell waste, as a representative renewable resource, can lead to serious environmental problems and resource waste if effective utilization methods are not developed. Therefore, there is an urgent need for innovative solutions enable the recycling reuse of marine waste. Although previous studies have explored applications shells in chitin extraction animal feed production, this study first reveal possibility obtaining metal resources from shells, which available large quantities. An analysis element concentrations shows that several valuable or important elements present at hundreds thousands times higher than seawater. CaCO3 was identified main component enriching shells. The recovery efficiency most oyster could exceed 80%. This highlights potential offering sustainable approach management while alleviating risk heavy accumulation pollution associated with traditional composting.
