“…The total amount of nickel consumption is predicted to be about 6000 kilotons in 2040, and the proportion of nickel consumption in batteries is estimated to be 41%. 98 The growing demand for nickel metal for batteries will put tremendous pressure on the sustainable supply of nickel in the future. The supply of nickel metal is affected by various factors such as national policies, wars, and emergencies.…”

“…Since this data is more than two decades, the current , concentrations can be considerably higher due to increased anthropogenic inputs as well as natural inputs. The Lake sediments in Sri Lanka recorded 1101 µg/g of REE (Table 3) because it is in the proximity of the Eppawala phosphate deposit [76]. Either REE containing source rocks or anthropogenic inputs, or both can be contribute for REE in all these sediments.…”

Currently, there is increasing industrial demand for rare earth elements (REE) as these elements are now integral to the manufacture of many carbon-neutral technologies. The depleting REE ores and increasing mining costs are prompting to look for alternative sources for these valuable metals, particularly from waste streams. Although REE concentrations in most of the alternate resources are lower than current REE ores, some sources such as marine sediments, coal ash, and industrial wastes like red mud are looking promising with significant concentrations of REE in them. This review focuses on the alternative resources for REE such as ocean bottom sediments, continental shelf sediments, river sediments, stream sediments, lake sediments, phosphorites deposits, industrial waste products like red mud, and phosphogypsum, coal, coal fly ash, and related materials, waste rock sources from old and closed mines, acid mine drainage, and recycling of e-waste. Possible future Moon exploration and mining for REE and other valuable minerals are also discussed. It is evident that REE extractions from both primary and secondary ores alone are not adequate to meet the current demand, and sustainable REE recovery from the alternative resources described here is also necessary to meet the growing REE demand. An attempt is made to identify the potential of these alternative resources and sustainability challenges, benefits, and possible environmental hazards to meet the growing challenges in meeting the future REE requirements.
