it ----.
Seaweed mining is an emerging approach in which A) eliminates the risk of environmental damage
marine algae are used to extract valuable minerals suffered by marine ecosystems
from seawater. These minerals include rare-earth
elements such as neodymium and europium, as well B) exclusively targets rare-earth elements, which
as other critical resources like lithium and cobalt are the most critical minerals
that are essential for clean energy technologies. C) avoids the utilisation of biofuels and bioplastics
Traditional mining of these resources is limited to a in clean energy production

Research shows that some algae species can deposits found on land

the ocean. The collected seaweed, often referred products at the same time
to as biomass, can be processed so that its stored
minerals become solid residues, while the rest can
be turned into biofuels or bioplastics. This dual
outcome makes the method both resource-efficient
and environmentally promising. Yet questions
remain about whether seaweed mining can be
scaled up to meet global demand. Scientists
continue to test how to maximise metal uptake
without harming ecosystems, leaving the future of
this method both promising and unpredictable.
