About a third of global food production is wasted. This amounts to 1.3 billion tons per year. This report was presented to FEVIA, the Belgian food industry federation, during a study day on lowering food waste.

This

food
from
field

a

chain
approach.
Using
the

we

this
process
in
Ame,
thereby
noAng
each
step
in
the
chain.

7. FARMING
&
POST-­‐HARVEST
In
the
late
80’s,
Mike
Yurosek,
California,
USA,
was
Ared
of
seeing
large
porAons
of
his
carrot
harvest
go
to
waste
because
they
did
not
match
the
high-­‐quality
appearance
of
a
full-­‐
grown
carrot
that
we
all
know.
At
first,
he
tried
feeding
his
rejected
carrots
to
his
pigs,
but
they
can
only
eat
a
certain
amount
of
carrots
before
their
fat
turns
orange.
Finally,
he
came
up
with
the
idea
of
cuMng
the
carrots
into
small,
5
cm
long,
pieces.
He
called
them
‘baby
carrots’
and
sold
them
for
50
cents
per
pound.
Compare
that
to
the
17
cents
he
got
for
one
pound
of
regular
carrots.

8. PROCESSING
In
order
to
lower
food
waste,
General
Mills
slightly
heats
their
pizzas
before
they
go
into
the
freezer.
This
melts
the
cheese
a
lible,
thereby
acAng
as
a
glue
to
keep
other
ingredients
stuck
to
the
pizza.

9. RETAIL
Willem-­‐Jan
Stam
owns
the
Dutch
food
outlet.
He
only
sells
food
products
that
are
rejected
by
other
supermarkets:
overstock,
bad
labeling
and
food
that
is
close
to
its
expiraAon
date.
His
outlet
is
a
true
success.
He’s
even
thinking
about
expanding
to
other
countries.
But
right
now,
he’s
too
busy.

10. RETAILER
The
famous
retailer
Tesco
uses
an
alternaAve
to
the
‘buy
one,
get
one
free’
promoAon.
Instead
of
that,
they
coined
‘buy
one,
get
one
free
later’.
Imagine
walking
home
with
2
breads
while
you
can
only
eat
one.
Instead,
you
purchase
your
bread
now,
and
pick
up
your
free
one
later.

11. Why
no
Trays?
In
order
to
reduce
our
carbon
footprint,
we
are
taking
a
closer
look
at
our
environmental
impact.
Food
Waste
When
students
use
plates
without
trays
the
amount
of
food
waste
decreases
by
one
ounce
per
plate.
Water
Usage
Research
also
shows
less
energy
is
consumed,
and
it
reduces
the
amount
of
water
and
detergents
used.
It
takes
1/4
gallon
of
water
to
wash
a
tray.
For
20
meals
in
a
week,
that’s
4
gallons,
or
skipping
one
shower
a
week.

12. Using
the
innovaAon
cross,
each
step
in
the
way
from
field
to
fork
is
mapped.
It
is
clear
that
we
have
to
work
on
each
step
of
the
supply
chain
to
solve
this
global
problem.
