What is Rare Earth Elements Recovery from Waste Streams?
Rare Earth Elements Recovery from Waste Streams involves solvent extraction, ion exchange, and bioleaching methods to separate REEs from electronic waste and magnets amid supply vulnerabilities.
This subtopic focuses on recycling REEs like lanthanum through cerium from e-waste using hydrometallurgical and bio-based processes. Binnemans et al. (2013) provide a critical review of recycling methods with 2199 citations. Over 20 papers in the provided list address REE recovery challenges in waste streams.
Why It Matters
REE recovery from waste reduces dependence on China's 90% supply monopoly, supporting wind turbines and EV motors (Alonso et al., 2012, 972 citations). It lowers environmental impacts from mining, with recycling potentially meeting 25% of demand by 2030 (Binnemans et al., 2013). Applications include battery recycling for EVs (Harper et al., 2019, 3261 citations) and nanomaterial wastewater treatments (Yaqoob et al., 2020).
Key Research Challenges
REE Selectivity in Mixtures
Solvent extraction struggles with similar ionic radii of REEs, reducing separation efficiency from e-waste leachates. Binnemans et al. (2013) highlight low selectivity of common extractants. Ion exchange resins face fouling from impurities (Sholl and Lively, 2016).
Scalable Waste Processing
Bioleaching yields low REE concentrations unsuitable for industrial scales from magnets and batteries. Harper et al. (2019) note economic barriers in EV battery disassembly. Alonso et al. (2012) project supply shortfalls without scalable recovery.
Environmental Toxicity Risks
Leachates from REE recovery contaminate water with heavy metals and organics. Gwenzi et al. (2018, 736 citations) document health risks from emerging REE contaminants. Life cycle assessments show high energy use in recycling (Nuss and Eckelman, 2014).
