Is car-steel’s fate in the hands of China’s fate? an input-output based material flow analysis of car-steel in China
Abstract
To
understand
the
change
of
car-steel’s
post-recycling
fate
of
China
in
the
last
30
years,
this
study
quantitatively
traces
the
fate
of
steel
recovered
from
end-of-life
(EoL)
cars
produced
in
different
years
by
using
the
Matrace
method
(Nakamura
et
al.,
ES&T
2014)
and
Chinese
input-output
tables
(IOTs)
from
1987
to
2007.
In
a
dynamic
setting,
we
consider
different
technology
and
economic
structure
scenarios
by
using
IOTs
of
different
years.
To
classify
the
destination
of
car
steel,
all
the
secondary
sectors
are
grouped
into
5
categories:
cars,
buildings,
civil
engineering,
machines,
and
others,
which
are
of
significant
importance
for
ferrous
materials.
The
results
show
that
most
of
the
car
steels
are
first
recycled
into
machines,
and
then
into
buildings.
Meanwhile,
once
a
unit
of
steel
has
been
used
in
car
production
in
1987,
the
peak
of
the
in-use
stock
of
the
steel
recycled
from
these
cars
appears
in
2000.
It
implies
that
the
gap
between
production
and
reuse
peak
is
13
years.
The
corresponding
gaps
for
the
cars
produced
in
the
year
of
1992,
1997,
2002,
and
2007
are
11,
11,
15,
and
15
years,
respectively.
We
also
witness
an
increase
of
the
quantity
of
car-steel
cycling.
Particularly,
the
proportions
of
car
steel
reused
into
cars,
machines
and
buildings
increase
over
time
with
the
growing
demand
for
cars,machines
and
buildings
in
China.
