Selective recovery of high value rare earth elements from end-of-life rare earth products is an economical and environmental measure. In this study, we used bio-based material (2,2,6,6-tetramethyl-1-piperidinyloxy-mediated bacterial cellulose) as the substrate material to construct a highly elastic imprinted bacterial cellulose aerogel (BCP-I) in synergy with chitosan (CS) and polyethyleneimine (PEI) for highly selective adsorption Er(III). CS and PEI contain abundant functional monomers, which can cooperate with bacterial cellulose and Er(III) to construct more imprinting sites, which not only improves the adsorption performance of BCP-I, but also makes the aerogel more stable. In order to analyze physical and chemical properties of aerogels, it was characterized by scanning electron microscope, fourier transform infrared spectrometer and thermogravimetric analysis. Adsorption experiments showed that BCP-I had a good adsorption effect on Er(III), and the maximum adsorption capacity could reach 95.99 mg g− 1. Cyclic experiments show that the adsorption property of BCP-I is still in good condition. All in all, BCP-I with environment-friendliness, high selectivity and good reproducibility is a good choice for recovery of Er(III).

“…Rare earth elements, known as "industrial vitamins", are widely used in catalysts, permanent magnets, glassmaking, lighting and other elds (Huang and Zhu 2019;Liang et al 2018;Ni'am et al 2020;Zhao et al 2019). Dysprosium (Dy) has always been one of the most important rare earth elements because of its irreplaceable role in optics and permanent magnets (Bisaka et al 2017;Fujiwara et al 2016;Liang et al 2018; Zheng et al 2020). Moreover,China has attached great importance to the rational development of rare earth resources in recent years.…”

Because of dysprosium's unique physical and chemical properties and limited supply, the price of rare earth dysprosium has been high in recent years. Therefore, the study of the method of high efficiency selective separation of dysprosium has the double value of scientific research and practical economy. In this paper, we used periodic cellulose nanocrystals as the basic structure, polyethylenimine and graphene oxide were introduced, combined with imprinting technology, to construct porous imprinted aerogel and use it for selective adsorption of Dy(III). The physical and chemical properties were characterized by SEM, TEM, FT-IR and TGA. It was proved that both polyethylenimine and graphene oxide were crosslinked effectively with cellulose nanocrystals. Adsorption experiments showed that the composite imprinted aerogel could selectively adsorb dysprosium effectively, and the maximum adsorption capacity for Dy(III) was 36.495 mg g− 1. The reproducibility experiment showed that aerogel had good regeneration ability. In conclusion, cellulose nanocrystals aerogel, which is environmentally friendly, efficient and repeatable, is expected to provide a new direction for the recovery of rare earth elements.

“…Kamenopoulos and Burford studied the criteria and indicators of sustainable development, with a focus on the criteria for and performance indicators of sustainable development in rare earth mining [14,15]. Liang et al applied the entropy method and grey relational analysis method, and developed a set of performance indicators for the sustainable development of rare earths in China, and evaluated the sustainable development of rare earths in China from 2006 to 2016 [16]. The results indicated that the main factor that affected the sustainable development of rare earths was a lag in the development of an environmental protection system and a rare earth protection system.…”

Intergenerational Externalities Influence for Exploitation Process of Rare Metal Minerals

Rare metal minerals are important strategic resources. Promoting the sustainable development of their mining process is not only related to energy and environmental issues, but also directly affects the sustainable development of the entire supply chain. Considering the influence of intergenerational externalities on the equilibrium in the rare metal mineral exploitation process is of critical significance to maintaining the sustainable development of rare metal minerals and securing a sustainable resource exploitation process. This paper develops a sustainability analysis model based on an intergenerational externalities influence and examines the influence of the shift in comprehensive production cost burden through the whole supply chain, which aims at the sustainable development of the exploitation process of rare metal minerals. The results indicate that in a vertically linked industrial chain, the upstream and downstream structure of the supply chain and the type of production cost are the factors that determine sustainable development. Upstream suppliers or countries should design their production systems based on their own circumstances. Specifically, when an upstream country has a low technological level for mineral exploitation processes and high development costs, a resource tax would be more effective in mediating sustainable development.
