Facilitated by Cultivating Community, CERES Community Environment Park and Environment Education Victoria.
A
We
run
three
program
areas,
I'm
the
team
lead
for
the
school
food
garden
program,
we're
probably
well
known
for
our
22
community,
gardens
that
we
manage
on
public
housing
estates
and
we
do
a
lot
of
work
in
food
systems
at
the
moment
running
a
project
called
moving
feast,
which
is
a
collaboration
of
enterprises
that
are
providing
food
relief
at
this
time.
So
we
envisage
a
joyful
connected
communities
who
care
for
each
other
and
at
the
earth.
A
A
I
thought
I'd
start
with
this
slide.
I
wonder
if
you
know
what
this
slide
is
off:
it's
actually
a
photograph
taken
from
a
place
very
close
to
where
I
live.
It's
in
black
rock,
it's
actually
a
midden
and
the
midden
is
a
place
where
the
aboriginal
people
would
come
together
around
the
campfire
and
anything
that
they
didn't
eat.
A
A
So,
firstly,
I'd
like
to
acknowledge
the
bunurong
people
of
the
kula
nation,
whose
land
I'm
presenting
on
today
to
acknowledge
the
elders
past
present
and
emerging
and
to
pay
my
respects
and
how
much
we
have
to
learn
about
food
waste
recycling
from
the
indigenous
people.
So
that's
just
to
put
a
bit
of
context
about
the
history
of
food
waste.
It
has
a
long
history
in
australia.
A
Aboriginal
people
have
been
here
for
over
220
000
years.
So
I'd
like
you
to,
firstly
think
about
why
you
are
here
welcome
today
and
what
is
it
that
you're
needing
from
this
presentation?
This
will
help
you
to
form
your
questions
as
we're
going
along
just
a
bit
of
a
general
introduction
to
food
waste
recycling.
A
A
It
provides
great
nutrients
for
your
garden
and
it
reduces
methane
gas
into
the
atmosphere.
That's
just
a
very
brief
outline
of
why
it's
really
important
for
us
to
be
recycling
our
food
waste,
but
why
food
waste
recycle
at
school?
What
are
some
of
the
motivations
that
you
have
to
food
waste,
recycle
at
your
school?
A
There's
lots
of
benefits.
Firstly,
the
learning,
there's
really
great
life,
hands-on
curriculum
activities
that
you
can
link
in
with
your
community
and
your
school
to
food
waste
recycling.
Your
grounds
will
appreciate
the
fact
that
your
food
waste
recycling
at
school
you'll
have
compost,
worm
castings
digestate
to
be
able
to
improve
the
soil
in
the
garden.
It
helps
to
reduce
weeds
decrease,
the
need
for
fertilizer,
improve
your
water
usage
and
better
manage
nutrient
runoff
there.
A
Of
course,
the
environmental
and
cost
benefits
to
the
school
it
reduces
waste
to
landfill,
reduces
greenhouse
gas
emissions,
in
particular
methane
gas,
and
will
reduce
the
school's
waste
disposal
costs.
But
mostly
it's
the
student
engagement
and
leadership
activities
that
come
from
food
waste
recycling,
many
of
the
food
waste
recycling
and
management
tasks.
Students
can
do
and
there's
lots
of
great
opportunities
for
learning
and
engagement
around
food
waste
recycling,
a
quick,
a
to
z.
A
What
are
some
of
the
behaviors
that
will
be
developed
and
that
I'll
be
covering
in
this
workshop
I'll
talk
a
little
bit
about
waste
avoidance,
it's
actually
more
important
to
avoid
food
waste
creation
than
to
recycle
it,
some
of
the
best
practice
for
food
waste
recycling
how
to
connect
with
people
around
the
topic
of
food
waste.
We'll
discuss
different
food
waste
recycling
options
when
you're
eating
more
consciously
you'll
be
thinking
a
little
bit
more
about
the
food
waste.
A
You'll
learn
the
science
of
decomposition
make
sense
of
what
methane
is
learn
some
new
terms
and
get
an
introduction
to
the
ph
scale.
Hopefully,
you'll
learn
to
observe
and
respond
correctly.
You'll
provide
valuable
nutrients
for
plants.
You'll
have
questions
to
ask,
and
hopefully
you'll
get
to
some
good
decisions.
From
this
workshop,
reduce
waste
to
landfill
there'll
be
support
available
to
you,
you'll
get
to
troubleshoot.
Your
problems
understand
there
are
different
recycling
systems,
you'll
get
to
value
food
which
in
turn,
values
your
soil,
become
a
worm
farm
advocate.
A
A
Secondly,
redistributing
food
to
people
rather
than
it
being
recycled
and
providing
animals
with
feed.
So
if
you
can
do
any
of
those
three
options
before
you
recycle
food
waste,
there's
something
that
you
can
think
about,
and
they're
really
important
in
the
perspective
of
best
practice
around
food
waste
recycling,
as
you
can
see
down
the
bottle
bottom
disposal
of
food
waste
to
landfill
is
the
least
preferred
solution.
A
So
what
is
food
waste
recycling
very
simply,
it's
taking
food
waste
and
turning
it
back
into
soil
that
can
be
used
to
grow
plants
such
as
food
plants
that
can
then
produce
the
food
that
then
becomes
the
waste.
So
it's
a
lovely
cyclical
production
so
that
food
waste
becomes
the
nutrients
again
for
the
plants.
A
This
is
a
great
activity
to
do
with
students
where
you
get
four
different
jars.
One
jar
has
a
lid
on
it.
One
jar
has
no
lid,
one
jar
has
the
apple
with
the
soil
in
it,
and
one
has
the
soil
and
composting
worm.
So
you've
got
four
jars
with
apples,
one
with
the
lid
on
one,
with
a
lid
off
one
with
soil
and
one
with
composting
worms.
A
A
Let's
have
a
brief
look
at
the
science.
I
don't
want
to
go
too
heavily
into
the
science,
but
firstly,
food
waste.
If
you
leave
it
on
your
desk,
it
will
start
to
decompose
and
the
reason
it
decomposes
is
because
there's
microorganisms
such
as
bacteria
that
are
in
out
in
the
oxygen
and
it
attaches
to
the
food
which
has
a
lot
of
water,
it's
very
high
in
water
and
very
high
in
minerals,
and
it
will
start
to
break
that
food
waste
down
and
what
it
creates
is
liquid.
A
Usually,
in
the
form
of
water
heat
and
a
gas
which,
if
there's
oxygen
present,
it
will
be
carbon
dioxide
and
we
call
that
aerobic
decomposition
when
food
breaks
down
in
the
presence
of
air.
When
we
take
down
away
the
air,
it's
called
anaerobic,
decomposition
and
methane
is
produced.
So
that's
the
process
of
food
decomposition.
A
A
A
So
when
food
waste
breaks
down
without
oxygen,
methane
is
produced
now
most
landfills,
because
they
don't
capture
that
methane
and
use
it
as
electricity
go
straight
up
into
the
atmosphere.
So,
by
getting
that
food
waste
out
of
landfill,
you're
reducing
the
amount
of
methane
that's
being
produced,
as
well
as
producing
fantastic
material
for
your
garden.
A
So
the
second
activity
which
is
fun
to
do
with
students,
is
to
take
the
number
of
common
household
objects
as
many
objects,
as
you
can
find
that
are
made
of
different
materials
enough
for
one
per
student
in
the
class
and
then
set
up
a
timeline
and
see
if
they
can
place
the
material
on
the
timeline.
In
terms
of
how
long
it
will
take
to
decompose.
A
Now,
some
materials
like
a
glass
bottle
would
take
a
million
years.
Things
like
toilet
rolls
will
take
one
year,
because
people
would
break
down
very
quickly
and
by
getting
the
students
to
really
think
about
how
things
decompose
over
time.
They'll
get
to
understand
not
only
the
importance
of
food
waste
recycling,
but
why
it's
important
to
recycle.
So
many
of
our
materials
that,
if
we
were
to
put
them
into
landfill,
would
sit
there
for
up
to
a
million
years
and
what
you
will
notice
from
this
activity.
A
So
the
three
systems
I'm
going
to
talk
about
today
are
composting
digestion
and
vermicomposting
or
vermiculture,
or
worm
farming,
whichever
you'd
like
to
call
that
one.
It's
got
lots
and
lots
of
names
and
we're
just
going
to
compare
the
three
systems
so
that
you
understand
the
different
sites
behind
each
of
them
and
why
you
might
choose
one
over
the
other.
A
A
So
I'm
going
to
start
with
the
composting
system
with
compost
bins.
Now
this
is
an
aerobic
decomposition
process
where
the
food
waste
and
the
organic
waste
are
actually
breaking
down
in
the
presence
of
oxygen.
So
the
most
important
thing
in
this
system
is
to
get
lots
of
oxygen
and
you're
aerating.
This
all
the
time.
A
I
recommend
having
a
closed
system
on
this,
keeping
it
covered
to
keep
out
rodents
and
we'll
talk
a
little
bit
about
that
later.
When
we
talk
of
of
schools
and
some
of
the
issues
that
come
up
in
schools
and
to
keep
it
moist
and
you
can
see
the
lasagna
picture
and
what
that's
really
showing
is
you
is
that
you
want
a
good
mix
of
materials.
A
It's
not
going
to
look
like
a
pile
of
lasagna,
but
it
is
going
to
have
different
materials
in
it
and
what
you're
trying
to
do
is
get
a
really
good
balance
between
these
four
things.
You
want
a
good
mix
of
greens,
which
bring
nitrogen
into
your
compost,
a
good
mix
of
browns
which
bring
carbon
into
your
compost,
then
some
moisture
which
the
microorganisms
need
to
generate
the
heat
to
start
breaking
down
the
plant
and
food
waste
and
lots
of
oxygen,
because
it's
the
oxygen
that
actually
feeds
these
microorganisms.
A
A
Now
there
is
a
little
bit
of
a
science
behind
how
much
carbon
and
how
much
nitrogen,
to
put
into
your
compost
every
single
material
has
a
different
ratio.
So
to
make
it
simple
the
way
I
get
people
to
think
about
it
is
in
terms
of
a
ratio
of
thirty
to
one
now,
because
food
waste
is
pretty
much
water,
90
or
plus
water.
A
A
Now
this
is
a
a
system,
an
open
bay
system.
The
challenges
with
open-based
systems
at
schools
are
rodents,
so
you're
going
to
get
mice
and
you're
going
to
get
rats.
If
you
put
food
waste
in
where
it's
very
open
I'll
show
you
later
a
system
where
they've
got
a
lid
on
it,
and
I
have
seen
some
schools
have
a
closed
bin
next
to
it.
So
the
food
waste
breaks
down
before
it
gets
added
to
the
compost
system.
A
So
what
does
compost
look
like
when
it's
ready
now?
It
should
be
the
color
of
dark
chocolate,
70
dark
chocolate,
but
it
doesn't
taste
like
chocolate.
Unfortunately,
it
is
very
fluffy
and
has
a
good
crumb
structure
and
when
you
squeeze
it,
there
should
be
a
bit
of
moisture
in
it.
It
should
smell,
sweet
and
earthy.
A
So
that's
really
what
you're
wanting
your
compost
to
look
like
at
the
end
of
the
process
now
in
terms
of
your
home
bins,
if
you
send
out
food
waste
or
green
waste
in
your
food
in
your
home
bins,
it
only
takes
seven
days
to
make
compost.
That's
how
quickly,
if
you're,
getting
the
right,
oxygen,
moisture
and
balance
of
carbon
and
nitrogen
composting
can
happen.
Really
really
quickly
and
it
can
create
compost
in
a
short
period
of
time
with
large
volumes
of
materials.
A
I
love
to
tell
schools
to
think
about
growing
some
compost
herbs
around
their
compost
bins.
So
this
petty
woodward's,
the
person
I'd,
recommend
if
you're
wanting
to
read
up
a
little
bit
more
about
it,
but
basically
it
adds
a
lot
of
these
micronutrients
back
into
the
soil.
So
these
plants
take
up
the
nutrients
in
their
roots
and
then,
when
you
compost
it
into
your
compost,
you're
adding
them
back
into
your
soil.
A
So
if
you
look
at
the
pictures
at
the
top
you'll
notice
that
there's
borage
yarrow
dandelion
nettle
fever
view
fennel,
tansy
and
comfrey
and
they're
just
a
few
of
the
plants
that
you
can
be
adding
into
your
compost
to
get
all
these
micronutrients
back
into
the
soil.
So
it's
a
great
thing
to
be
doing
at
schools.
A
I
might
actually
go
back
because
the
ph
scale
is
exponential,
so
an
acid
sitting
at
six
is
ten
times
stronger.
So
as
you
move
away
from
seven,
it's
becoming
exponential,
so
number
five
is
a
hundred
times
stronger
acid
than
a
thousand
ten
thousand,
a
hundred
thousand
a
million
ten
million
times
stronger.
So
by
the
time
you
get
to
zero,
these
acids
are
very,
very
strong
and
dangerous.
So
we're
talking
about
a
lot
of
strength
here.
A
A
Ph
kits
can
be
purchased
from
hardware
stores,
they're,
not
very
expensive,
and
they
last
a
long
time
and
kids
absolutely
love
it
because
they
change
colors,
so
getting
them
to
test
I'd,
suggest
getting
them
to
test
some
compost
and
soil.
Some
worm
castings
some
digestate,
whatever
you
might
have
around
and
when
you're
looking
to
test
your
soil
you're
looking
for
it
to
sit
in
that
range
of
six
and
a
half
to
seven
and
a
half
so
you're
matching
the
color
on
the
scale.
A
Fun
things
to
do
is
once
you've
matched
the
color
to
see
what
happens
when
you
add
things
like
lemon
juice
and
once
kids
have
gone
through
the
activity
of
understanding
the
difference
between
alkalines
and
acids,
they
should
be
able
to
guess
which
way
the
color
color's
going
to
go.
So
you
can
have
a
lot
of
fun
with
this,
and
the
students
will
really
enjoy
it.
A
Compost,
troubleshooting,
there's
really
those
four
elements
that
I
talked
about:
moisture
oxygen,
nitrogen
and
carbon
at
the
areas
that
you'll
start
to
see
problems
if
things
are
out
of
balance.
So
if
you
don't
have
enough
moisture,
you'll
notice
that
your
compost
feels
really
dry
and
looks
really
dry,
and
luckily
the
solution
is
very
easy.
It's
just
adding
water
I
tend
to
when
I
add
a
bucket
of
food
waste,
a
bucket
of
carbon.
I
also
add
a
bucket
of
water
just
to
make
sure
my
compost
bin
has
got
the
right
moisture.
A
If
things
start
to
smell,
it
starts
to
clump
it
slows
down.
Then
you
haven't
got
enough
oxygen,
so
getting
an
oxy,
getting
a
compost
turner
using
a
fork,
some
spades
getting
oxygen
into
the
mix.
Turning
it
over
will
actually
help
to
accelerate
how
quickly
it
all
breaks
down
if
you're
lacking
nitrogen,
it
won't
decay
well
enough,
which
means
you've
got
too
much
carbon
and
not
enough
food
waste
in
your
system.
So
you
need
to
balance
that
out
out
and
add
more
food.
A
So
I
really
suggest
thinking
about
a
closed
system
when
you've
got
food
waste
being
put
in
here's
some
examples
of
different
systems
that
I
see
around
the
place
and
just
some
really
good
ideas.
So
in
the
top
left
corner
there's
a
new.
This
is
a
new
compost
bay.
That's
gone
into
spotswood
primary
school,
the
one
at
the
top,
which
just
shows
the
food
waste.
A
So
it
was
like
a
tiered
system
like
ladder
like
a
step
ladder
going
down
the
hill,
and
it's
quite
an
unusual
compost
system,
the
one
with
the
lid
on
it
is
actually
a
community
compost
system
at
the
city
of
melbourne
and
they've
got
a
lid
on
to
keep
rodents
out
and
that's
what
I
suggest
for
the
first
bay.
If
you're
at
a
school
is
to
have
something
to
prevent
rodents
getting
into
your
system,
you
should
be
able
to
feel
the
warmth
in
a
compost
bay,
especially
as
the
compost
starts
to
break
down
very
quickly.
A
It
can
get
up
to
75
degrees
in
a
good
compost.
So
if
you've
got
a
thermometer,
kids
would
probably
love
to
test
the
temperature
over
time
to
see
how
hot
the
compost
system
is
going.
You
can
always
give
free
compost
away
to
your
community,
there's
a
sign
there.
That
shows
you
how
to
promote.
What's
going
on
with
your
composting
system,
I
love
this
one
because
it's
been
done
by
children
and
it
shows
them
what
they
can
put
in
and
what
not
to
put
in
this
compost
caddies
some
upcycled
buckets.
You
don't
need
to
purchase
them.
A
You
can
upcycle
old
containers
to
collect
your
food
waste
to
take
to
the
systems.
I
really
like
the
way
up
system
here
where
people
are
measuring,
how
much
food
waste
is
going
in
before
it
goes
in.
So
it's
all
set
up
next
to
the
compost
base,
there's
a
scale
there's
a
bucket
with
a
clipboard
and
a
pen.
So
every
time
food
waste
is
added.
It's
weighed
before
it
goes
in,
so
you
can
get
some
really
good
data
on
how
much
food
waste
is
being
diverted
from
landfill.
A
Next
we're
going
to
move
on
to
a
food
digester.
Now
food
digestion
is
a
bit
different
in
that
words
anaerobically
without
oxygen,
so
there's
no
oxygen
in
this
system,
so
what
you're
doing
is
you're,
adding
just
food
waste,
no
garden
waste.
This
is
great
for
schools
that
have
limited
space
and
have
no
gardens
that
you
can
be
digesting
your
food
anaerobically.
A
You
do
need
to
add
a
micro
brand,
so
this
brand
has
been
fermented
with
bacteria
that
thrive
in
anaerobic
conditions.
They
love
the
fact
that
there's
no
oxygen
and
they
will
break
down
the
food
really
quickly
so
you're,
adding
your
food
waste
to
the
system
and
you're
draining
it
all.
The
time
you
might
have
heard
me
say
that
food
waste
is
up
to
90
water.
A
lot
of
liquid
will
come
out
very
quickly,
and
these
can
get
very
smelly
if
you
don't
drain
them
daily.
A
A
So
just
a
little
bit
of
a
comparison
to
show
you
how
it
all
works,
digestion
uses
fermentation.
While
composting
uses
heat
to
break
down
the
food
waste
fermentation,
you
don't
lose
as
much
nitrogen,
but
you
do
lose
it
in
the
composting
process.
Digestion
produces
methane.
While
composting
produces
carbon
dioxide.
A
A
You
need
to
actually
be
balancing
the
carbon
and
the
nitrogen
so
that
you're
getting
a
good
balance
of
both
so
that
the
bacteria
can
thrive.
So
it
breaks
down
beautifully
now.
The
beauty
of
digestion
is
that
you
can
add
meat
ways
safely
and
you
can
add
dairy
waste,
so
things
that
you
can't
add
to
your
compost
system.
A
You
can
add
to
a
digestion
system,
so
the
only
place
I
would
recommend
you
putting
in
meat
waste
or
dairy
waste
is
into
a
system
that
uses
anaerobic
decomposition
because
that's
the
safest
way
to
prevent
any
pathogens
from
entering
in.
There
are
green
cones
which
can
be
used
outside
and
it's
a
much
simpler
system.
It
looks
like
a
compost
bin,
but
it's
actually
a
digester
and
the
food
waste
is
under
the
ground.
So
all
those
nutrients
go
directly
into
the
soil.
A
You
would
need
at
least
two
to
four
of
these
at
a
school
and
you
would
need
to
probably
relocate
them
every
one
to
two
years
and
dig
a
new
hole
and
put
them
in,
but
that's
a
digestion
system
as
well.
The
only
advantage
of
this
one
is,
you
only
need
to
add
the
bacteria
at
the
beginning
and
it
will
multiply
in
the
soil.
So
every
time
you
set
up
the
system,
you
add
some
of
that
bacteria.
A
A
Unfortunately,
I've
seen
a
lot
of
worm.
Farms
located
in
full
sun
in
many
schools
and
the
worms
don't
fare
too
well
over
summer.
Unfortunately,
most
systems
work
where
you're
adding
food
waste
at
the
top
and
you're
collecting
the
worm
castings,
which
is
a
fancy
word
for
worm,
poo
and
worm
tea,
which
is
a
fancy
name
for
worm.
We
at
the
bottom
now
the
worm,
tea
or
the
worm.
We
needs
to
be
diluted
again,
like
cordial,
tend
to
one
and
the
worm.
Castings
are
quite
alkaline.
A
Worms
love
to
live
in
a
habitat
that
is
very
alkaline,
which
means
that
you
want
to
just
spread
them
on
quite
thinly
when
you're,
adding
them
to
your
soil.
You
wouldn't
use
them
in
the
same
way
that
you
would
use
compost
over
winter
worm
activity
slows
down.
Now
I
am
going
to
tell
you
later
about
some
worms.
You
can
purchase
from
a
place
called
kookaburra
worms
and
they
have
five
species
of
worms
in
their
mix
and
what
that
does
is
worms
that
are
more
active
in
winter
will
kick
into
gear.
A
The
only
time
you
need
to
really
care
for
these
systems
is
on
very
hot
days,
especially
those
40
plus
days,
and
that's
where
I
see
a
lot
of
worm
farms
in
schools.
Unfortunately,
the
worm
populations
die
off
over
summer
need
to
be
started
again.
Usually
there's
enough
worm
eggs
in
the
mixture
to
hatch
once
a
population
dies
off,
but
it
does
take
a
time
to
build
up
the
system
again
so
you're
better
off,
not
allowing
your
worm
farm
to
die
off
over
the
holidays.
A
There
are
different
types
of
worm,
farms
and
I'll
show
you
one
later
that
bring
bank
council
is
offering
apartment
blocks,
which
are
a
bit
like
a
tower
like
an
apartment
tower
for
worms,
work
on
a
very
similar
system
and
you
can
easily
move
the
trays
in
and
out
of
these
systems.
I
really
love
the
worm
towers
that
have
come
onto
the
market.
I
think
they're
fantastic
for
the
early
years
for
the
preppies
for
the
grade
ones
to
have
a
really
hands-on
connected
experiencing
of
connecting
to
worms
in
the
food
garden.
A
So
if
you
have
a
food
garden
and
you
have
preppies
and
grade
ones,
that
would
love
to
do
a
hands-on
activity.
I'd
suggest
setting
up
a
worm
tower
with
them
so
great.
In
early
childhood
centers
as
well
and
at
home,
I've
got
quite
a
number
around
my
fruit
trees,
fruit,
trees,
love
them
a
fun
activity
to
do
with
students
is
to
make
worms.
That's
a
worm
made
of
some
upcycled
materials,
some
upcycled
stockings,
some
recycled
paper
and
some
elastic
bands
so
fun
to
learn
about
worms
too.
A
There's
many
different
types
of
worms
over
3500
different
species.
Australia
has
the
largest
earthworm
in
the
world,
the
east
gippsland
worm,
which
can
grow
up
to
three
meters
long,
it's
a
very,
very
large
worm
and
can
live
up
to
75
years.
So
there's
lots
of
interesting
fact.
Probably
my
favorite
fact
is
that
worms
have
five
hearts
so
they're,
very,
very
loving
creatures.
You
can
learn
about
all
the
different
parts
of
their
body
and
how
they
break
down
the
sugars.
A
The
bacteria
produce
to
help
as
part
of
that
decomposition
cycle,
so
they're
not
actually
eating
food,
they
don't
have
teeth,
but
they
help
the
decomposition
process.
So,
as
bacteria
starts
to
break
down
the
food,
then
the
worms
can
feed
off
all
those
beautiful
sugars
and
that
goes
through
their
digestive
system.
A
So
their
role
in
the
soil
is
to
aerate
the
soil.
They
allow
water
to
penetrate
deeper
down
they're,
forming
lots
of
holes,
leaving
lots
of
fertilizer
as
they
do
their
worm
castings
as
they
go
along.
So
learning
about
the
importance
of
the
ecosystem
and
having
worms
in
ecosystems
is
really
important.
A
This
is
a
very
simple
upcycled
worm
farm
that
I
saw
at
a
school
that
I
really
loved.
It's
a
bath.
That's
been
attached
to
a
table
and
they've
got
a
bucket
to
collect
all
the
wormweed
at
the
bottom.
Some
hessian
sacks
and
they've
converted
some
drawers
with
some
wire
to
prevent
rodents
from
getting
in
and
a
carpet
some
carpet
on
top
and
they
had
it
perfectly
located
on
a
south-facing
wall.
So
there
was
no
sunlight
at
all
during
the
day,
so
it
was
kept
nice
and
cool.
A
Now
this
is
the
system
that
council
is
operating.
It's
a
promotion
for
schools
in
the
city
of
brimbank,
it's
the
worm
farm
grant
and
it's
it's
basically
open
to
a
one-on-one
basis.
So
if
your
school
can
raise
hundred
dollars,
then
the
council
will
put
in
the
other
fifteen
hundred
dollars
to
set
up
a
commercial
size,
worm
farm
at
your
school
and
the
council
will
gift
its
contribution
to
you.
So
there
are
limited
numbers
available.
A
It's
our
first
come
first
serve
basis,
and
you
need
to
express
your
interest
so
speak
to
your
bring
bank
10
officer
today
and
she'll,
be
able
to
tell
you
a
little
bit
about
how
you
might
be
able
to
get
hold
of
one
of
these
worm
farms
for
your
school.
Now,
as
I
mentioned,
the
worms
down
under
you
can
see
a
little
bit
about
how
these
systems
work.
So
there
is
a
link
to
the
system
if
you'd
like
to
do
a
little
bit
of
research
about
it.
A
So
making
the
choice
is
quite
simple:
it's
thinking
a
little
bit
about
the
setup
cost
how
much
it's
going
to
cost
to
set
up
your
system
at
the
school
in
terms
of
ongoing
cost.
It's
really
only
digesters
that
have
an
ongoing
cost
unless
you
unfortunately
lose
your
worm
population
over
summer.
So
it's
really
the
digester
that
you
need
to
be
thinking
about
getting
the
fermented
bran
in
they
all
have
different
capacities.
A
So
really,
you
need
to
understand
how
much
food
waste
your
school
is
producing
to
know,
which
is
the
best
systems
for
your
capacity
of
food
waste,
and
that's
something
that
you
have
to
do
a
little
bit
of
research
and
a
little
bit
of
thinking
about
the
only
system
that
you
can
add
meat
and
dairy
products
to
safely
so
that
pathogens,
don't
breathe,
are
digesters
or
a
digestion
system
that
uses
anaerobic
decomposition
and
compost.
Bins
are
the
best
for
adding
garden
waste
worm.
Farms
are
the
only
system
that
need
to
be
in
full
shade.
A
The
others
need
full
sun
and
you
end
up
with
different
products
at
the
end.
So
you
end
up
from
a
compost.
Bin
you'll
end
up
with
some
compost,
a
digester
you'll
get
liquid
fertilizer
and
organic
matter
that
you
bury
into
the
soil
from
a
worm.
Farm
you'll,
get
worm,
castings
and
worm
tea,
so
you
do
end
up
with
different
products
and
they
all
have
different
advantages
and
disadvantages.
A
Suppliers
there's
an
abundance
of
suppliers.
I
just
put
a
few
down.
You
can
get
lots
of
worm
farms
from
bunnings
compost
revolution.
You
can
create
your
own
out
of
pallets.
There's
lots
of
ways
to
get
this.
The
kookaburra
worm.
Farms
are
the
ones
I
mentioned
before,
where,
if
you
wanted
five
species
of
composting
worms,
composting
worms
are
very
different
to
your
earthworms
earthworms.
A
Don't
break
down
the
food
waste
quick
enough,
they
don't
eat
the
composting.
Worms
are
actually
a
type
of
worm
that
lives
in
humid,
dense
environments
and
its
role
is
to
break
down
plant
matter
very
quickly.
They
can
eat
their
body
weight
every
day,
so
they're
a
different
type
of
worm.
So
there
are
lots
of
places
you
can
buy
worms
from,
but
kookaburra
worms
have
the
most
interesting
range.
I
think
for
children
to
be
looking
at
different
worm
species.
A
Just
to
give
you
a
little
big
picture,
I
always
think
it's
good
to
have
a
big
picture
in
terms
of
food
waste
recycling
around
melbourne
we're
starting
to
see
a
lot
of
businesses
starting
to
incorporate
food
recycling
into
their
practice.
There's
a
picture
of
degrade
street.
They
have
a
machine
called
an
orca
and
their
orchid
turns
the
food
waste
from
all
the
businesses
into
grave
street
into
sewerage,
which
goes
down
the
sewage
pipe
they've
tried
a
few
different
systems
dehydrators
one
with
different
microorganisms.
A
But
it's
good
to
know
that
this
is
happening
in
the
top
right
corner.
You'll
see,
what's
called
a
tap
g
model
and
that's
pretty
much
a
commercial
scale,
worm
farm
and
that's
at
hillsville
sanctuary.
So
if
you
ever
got
the
opportunity
to
go
to
hillsboro
sanctuary
you,
you
could
actually
have
a
look
at
the
commercial
sized
worm
farm,
the
one
that
looked
like
cylinders
underneath
that's
at
federation
square
that
uses
anaerobic
decomposition
and
all
the
energy
is
used
to
power
fed
squares.
A
So
you
probably
don't
know
that
that
happens
underground,
but
their
food
waste
is
producing
the
energy
that
that
is
used
at
fed
square
worm.
Farm
bins
can
be
put
in
meth,
just
simple
solutions:
a
whole
lot
of
hungry
bins
in
a
line,
so
you
can
use
worm,
farms
and
then
down.
The
bottom
is
a
a
an
amazing
machine.
A
That's
at
the
royal
melbourne
zoo
and
it's
an
in-vessel
composter
and
the
food
waste
goes
in
one
end
and
seven
days
later
it
comes
out
the
other
end
and
they
turn
it
into
a
product
called
zupu
that
you
can
purchase
from
different
gardening
supply
stores.
So
lots
of
places
around
melbourne
where
food
waste
recycling
is
becoming
the
norm
has
taken
a
while,
but
we
are
starting
to
see
it
lots
of
fantastic
resources.
A
A
This
recycling
food
waste
at
school
document
is
actually
very
old,
but
I
still
think
it's
got
a
lot
of
great
information
in
it.
If
you're
interested,
I
can
send
a
copy
to
you,
there's
also
the
resource.
Smart
waste
modules
and
great
curriculum
links
on
their
website.
They've
got
a
waste
module
checklist,
a
resource,
smart
waste,
how-to
guide,
a
waste
audit
for
secondary
schools,
curriculum
links
around
sustainability
that
also
focus
in
on
waste,
so
lots
of
opportunities
to
link
all
this
food
waste
recycling
into
the
curriculum.
A
Now,
how
do
you
get
a
successful
program
up
and
running
at
a
school?
The
most
successful
schools
I've
seen
is
that
they
get
everyone
on
board
from
the
principal
the
teachers
to
the
students
having
a
whole
school
team
approach
is
the
best
way
to
get
a
really
successful
food
waste
recycling
system
up
and
running,
making
sure
that
it's
student-led,
because
students
are
great
at
leading
these
sorts
of
programs
linking
it
into
the
curriculum.
A
So
if
you
need
any
assistance
with
your
food
waste,
avoidment
avoidance
or
food
waste
recycling
schemes
at
your
school,
you
can
always
contact
me.
We
also
do
work
around
community
gardens
in
urban
agriculture,
food
growing
at
home,
protecting
projects
that
build
community
through
engagement
and
making
the
most
out
of
outdoor
classrooms.
So
if
you
need
any
support
with
your
food
garden
system
or
your
food
waste
recycling
system,
we
can
help
you.
A
So
thank
you.
These
are
my
contact
details.
You
can
always
email
me
if
you
have
any
further
questions,
I'm
going
to
be
opening
it
up
for
questions
now,
but
before
I
open
it
up
to
questions,
I
have
some
lovely
news.
There's
two
schools
that,
as
of
because
of
last
week's
workshop,
went
into
a
random
draw
and
have
received
a
special
prize
they're
going
to
receive
up
to
10
cubic
metres,
each
of
compost
and
the
lucky
schools.
A
From
last
week
from
attending
our
food
gardening
workshop
are
deer
park,
north
primary
school
and
lawrence
primary
school,
so
an
officer
will
be
in
touch
with
you
very
soon
to
organize
all
the
details.
So
congratulations
to
dear
pa,
north
primary
school
and
so
lawrence
primary
school.
You've
won
yourself
some
compost
without
having
to
do
all
the
hard
work
which
is
fantastic.
So
well
done
so
now,
we've
got
questions.
A
A
A
Now
I
have
been
to
many
many
schools.
I
do
a
lot
of
support
for
schools
in
setting
up
their
food
waste
recycling
system,
and
one
of
the
things
I
find
when
I
go
to
schools
is
that
they
don't
have
an
understanding
of
how
the
different
systems
work
so
having
a
basic
understanding
of
how
they
work
will
help
to
make
you
make
better
decisions
about
what
you
need
to
put
in
place
and
how
they're
going
to
be
managed.
A
A
I
don't
seem
to
have
any
so
no
questions
are
coming
through.
So
I'd
like
to
finish
off
the
webinar
and
say
thank
you
to
everyone
for
coming
this
afternoon.
I
am
available
to
answer
any
questions
you
can
email
me.
There
will
be
a
copy
of
this
presentation
that
will
be
sent
out
as
well
as
a
link
to
this
webinar,
so
you're
quite
welcome
to
forward
the
lab
webinar
to
any
other
staff,
members
or
school
members,
or
parents
or
students.
If
you
want
to
entice
them
to
get
on
board
with
your
school
system.
Here
we
go.
A
A
A
A
Hopefully
the
education
campaign
around
your
school
will
talk
about
different
ways
that
you
might
be
able
to
prevent
that
food
waste
happening
so
not
whole
pieces
of
fruit
getting
into
the
system
that
you
actually
start
to
make
students
and
staff
aware
of
how
important
it
is
to
eat
food
because
of
all
the
food
grown
50
of
it
ends
up
wasted
that
doesn't
even
get
eaten
so
how
important
it
is
and
how
precious
our
food
is.
A
Anyone
who
has
a
food
garden
program
at
the
school
will
know
how
important
it
is
to
eat
food
because
it
takes
so
much
time
and
energy
and
resources
to
grow
the
food.
So
you
get
some
great
things
happening
so
in
terms
of
some
of
the
solutions
in
a
compost
system.
The
only
way
to
you
won't
prevent
it
from
happening
because
it
is
supposed
to
break
down
it
is
supposed
to
go.
Sludgy
is
to
add
more
carbon.
So
in
a
compost
system
you're
adding
the
carbon
in
a
worm
farm
system,
it
is
going
to
go
sludgy.
A
That's
just
what
food
waste
does
in
a
worm
farm
system,
it's
breaking
down!
It's
decomposing!
As
long
as
you're
draining
out
the
liquids,
it
should
keep
moist.
You
can
add
some
paper
if
you're
finding.
You
need
to
soak
up
a
bit
of
that
moisture,
but
pretty
much.
That's
the
natural
process
of
decomposition
food
waste,
no
matter
what
we
do
with
it
will
eventually
break
down.
So
if
we
leave
it
on
our
desk
for
six
months,
it
will
break
down
into
mush.
That's
what
food
waste
does
so
there's
nothing
wrong
with
the
system.
A
Only
if
it's
creating
a
smell
or
if
it's
attracting
rodents,
you
can
chop
things
up
quicker,
the
more
oxygen
around
the
food
waste
in
a
composting
system
and
a
worm
farm,
the
quicker
it
would
break
down
because
the
it's
got
more
access
to
oxygen.
So
the
tinier
the
pieces,
the
more
surface
area,
the
more
oxygen,
the
quicker
it
breaks
down.
So
you
don't
end
up
with
as
much
sludge.
A
Whole
pieces
of
fruit
become
sludgier
because
it's
the
outside
breaking
down
first
over
time
in
terms
of
the
effectiveness
of
the
system,
they're
still
going
to
work,
sometimes
it's
just
our
grossed
out
sense.
We
get
a
bit
grossed
out
when
we
see
this
sort
of
happening,
but
it's
actually
fine
from
a
from
a
systems
perspective,
so
it
will
break
down
over
time.
A
That's
probably
the
best
answer.
If
you
have
any
more
further
questions
around
that
answer,
please
let
me
know,
I
think
it's
great,
that
you've
got
a
whole
food
approach,
a
whole
school
approach
to
food
scrap
collection,
because
that's
one
of
the
most
important
things,
and
sometimes
you
can
introduce
challenges
around
the
least
amount
of
food
waste
being
produced
per
class.
A
So
building
incentives
can
be
a
behavioral
change
that
you
might
like
to
do
as
a
really
good
whole
of
school
strategy
to
stop
those
whole
pieces
of
fruit
going
in
and
thinking
creatively
about
other
fuses
that
you
might
have
for
those
whole
pieces
of
fruits
if
your
school
has
chickens
or
if
someone
can
collect
those
whole
pieces
and
take
it
home
to
their
pets,
so
it
can
get
reused
and
used
as
animal
filter
before
it
becomes
food
waste.
So
there's
some
of
the
suggestions
I
have.
A
If
there
are
any
more
questions
start
to
post
those
because
we
are,
we
still
have
10
more
minutes.
So
if
there's
any
questions,
you
would
like
around
any
of
the
three
systems,
whether
you
have
questions
around
composting
digestion
or
food
waste
recycling
and
worm
farming,
so
any
of
those
sort
of
areas
that
you've
got
an
interest
in.
A
I
know
when
people
registered
there
was
a
lot
of
questions
about
engagement.
It
does
take
time
in
schools.
I
find
schools
with
food
garden.
Programs
tend
to
do
a
lot
better
with
their
food
waste
recycling
system,
because
it
makes
a
lot
more
sense
to
have
it
in
place,
and
usually
there
are
people
in
place,
sometimes
garden
educators
that
can
take
on
that
responsibility.
A
It
does
take
time
being
part
of
this
resource.
Smart
program
also
does
give
leverage
to
having
a
whole
school
approach
to
food
waste
recycling
and
it's
great
to
start
early,
especially
from
prep.
All
the
way
up
to
grade
six
in
a
school
doesn't
look
like.
We've
got
any
more
questions
coming
through,
so
I'm
going
to
end
the
presentation.
Now,
I'm
going
to
say
thank
you
for
all
coming.
Congratulations
again
to
deer
park,
north
primary
school
and
st
lawrence
primary
school.
Thank
you
to
brimbank
council
for
hosting
today's
webinar.
A
Oh
look,
we've
got
one
question.
Just
got
it
in
on
time.
Can
worms
tolerate
any
amount
of
citrus
worms
can
eat
anything
so
in
terms
of
food
and
fruit
and
vegetable
waste,
the
issue
isn't
to
do
with
the
food,
so
food
will
break
down.
The
issue
is
with
the
ph.
So
what
happens?
Is
that
citrus,
as
you
would
have
seen
on
the
ph
scale,
is
highly
highly
highly
acidic
and
worms
love
to
live
in
a
beautiful
alkaline
environment.
A
So
when
we're
adding
citrus
foods
to
our
worm,
farms
we're
changing
the
ph
of
their
ecosystem.
So
it's
not
that
they
can't
eat
citrus,
it's
not
that
they
won't
eat
citrus.
It's
just
that.
We're
changing
the
ph
now,
there's
a
few
things
you
can
do.
Small
amounts
are
probably
not
an
issue.
In
fact,
it's
probably
a
good
thing.
My
worm
farm
is
too
alkaline,
so
adding
some
citrus
is
a
good
thing.
A
You
can
also
count
to
balance
it
once
a
week
once
a
month,
depending
on
how
much
citrus
you're
adding
you
can
sprinkle
some
lime
onto
your
worm
farm,
which
will
counter
balance
that
acidic
acidity
of
the
citrus
fruit.
So
as
long
as
it's
a
balance
that
you're
adding
what
you'll
find
is
that
the
citrus
food
will
break
down
slowly
and
the
worms
will
probably
avoid
that
area,
because
it's
quite
acidic,
but
eventually
it
will
stabilize
out
and
it
will
break
down
in
the
system,
so
don't
be
too
concerned
about
citrus.
A
I
put
everything
into
all
of
my
systems
and
I've
been
doing
it
for
30
years
and
that
have
never
had
any
issues,
so
it
all
works
really
really
well
so
great
question,
thank
you
for
that
question.
I'll
publish
it.
I
don't
know
if
everyone
got
to
see
that
question
and
I
think
that's
it.
So.
Thank
you
thanks
again,
thank
you
to
bring
bank
council
for
today's
pd.
If
you
have
any
questions,
please
contact
me
have
a
great
day
see
you
later.
