Abstract
Mitigating
embodied
emissions
is
becoming
increasingly
crucial
as
the
energy
supply
shifts
toward
more
sustainable
sources.
Bio‐based
materials
present
a
potentially

to
synthetic
polymers;
however,
it
often
do
not

materials.
Given
ongoing
reliance
on
high‐performance,
high‐environmental‐impact
materials,
essential

their

recyclability.
Aerogels,
recognized
by
IUPAC
one
top
ten
emerging
technologies,
are
witnessing
rapid
market
growth
in
thermal

and
protection
applications.
In
certain
applications,
composite

exhibit
superior
performance,
particularly
under
high
temperatures.
Here,
