Aquaponics | Ward Bosmans | TEDxMechelen


good evening everyone up to a year
ago I was an expert
sustainability at a company
you would think they were someone with such
function not in house
I was specialized and especially in it
renewable energy and energy saving
in electric cars but also in
Corporate Social Responsibility
and married in the job years ago
after a career of more than thirty years
at that company I heroes that job
a
for a job as a freelance journalist and
consultant consultant in the field of
sustainability also or a I have that 30
year
certainly very amused at angie
electrabel but now actually mark
especially journalist and one of the first
assignments I received from the paper
to make an article about a young one
entrepreneur who was working with a system
he in a very sustainable way
both dirty and eggs as well as vegetables
bred
and to my great surprise it turned out
young entrepreneur called glenn and round
physically still in the same street a
few houses further and I still had
never heard of it
when he explained the system to me
aquaponics is the name of the system
fibula of my chair and cynical that
moment actually since a year ago
I’m also going a bit more
to deepen and it is a lot on me
a lot of fun that I give you one tonight
explain a little what that means or what
that is
aqua police but first I take you
to the 70s I was a small
male that smalljans can be around ten
year about
and I live in lifting lifting is one
district of mechelen and he was full
then also really with lifting in turn and in
our garden in our old ugly garden
all there grew vegetables I
to this day I taste
neither my mouth nor the taste of the fresh
crunchy and skirts that we like the
city ​​pulled the the cap to be we strong
is in our mouth your sweet crunchy
taste
carrots that joy that come out
the ground we went there is more about us
and we ate diaz snack
our chickens who laid fresh every day
eggs and as a mother bakes every morning
deneyer
eggs and we got bacon my own
between our sandwiches that work well
so say yes I used to be one
all better certainly no happy not
because it is not that bad either now
but just as I are probably
this the peas
that you eat today I ‘m going all out too
the supermarket
and yes we always taste them
saviors but they are no longer such
crispy and as sweet and as fresh as that
from the past
and these are the carrots that come with it
from the supermarket that his uncle
naturally big and I have no visibility
to come from or work for me
products that have all been treated
she was just like you
and the chickens for eggs when I have eggs
park in the supermarket then I can watch
I always mention that he is in one of them
type of screen or type of scale on eggs
they still have a bit more run-out
space than the keeper in the battery
the I have looked up a picture of such
free-range chickens these are the
free-range chickens
well it is all the same today
not bad because fortunately there are more
and more people who go more vegetables
food that they also grow themselves
just think about baking the square meter
some people are standing in their garden
often have schools
you can even find chicken coops nowadays
in schools the children learn on that
way back to deal with vegetables
more and more vegetarians are coming
also get a bio warranty
and they will be our flesh today
broth
yes or not
it shows more sustainably that I experienced
when I was in my street at that
entrepreneur because article to write
it can be more sustainable and more sustainable
shows the ham
because the water availability per
person per year in belgium is not
to
to blow the tower soon
we with 10 billion people on this planet
and all 10 billion we have to live
Gene that our world offers
earth if has to offer and the
water sources that d’r are the ground each
is
and the paradox is that that water and
that fertile soil in one
higher tempo disappears
and if you think of a distant land
is this is a a study of professor
willems van de kuleuven from last year
that proves that we are in Flanders
do not have an abundance of water and
that in the future only
will be worse
so it can be better it should be better now
that there is a systemic
wish your own vegetables want to grow that
you are completely provided for
whole family for a large period
of the year
bio vegetables were a perfect sight on
from where they come from to the ge
they have grown them yourself
do not have to kick
do not have to hoe in the garden
voice had a exists and that in addition
you are not completely organic
pesticides do not need that too
insects come to those vegetables
against
moreover, no water or very little
water need much more than when
you live much less than when you
grow vegetables in the garden
that you do not need much space on it
that can go on a few square meters
and that you also see that
vegetables grow much faster
it may seem a bit utopian perhaps
yet it exists and the system
hot is all degrees
klaplong nothing what is the property
aquaponics is actually very simple
system
you leave an aquarium or save
then say to bin where fish is seeing and
you see here on the close that
fish that feeds you
and that is also the only input that
you have to care about the whole system
the food for the fish when you cycle
is progressing just like we should
unburden
who will not have to toilet but
those cats just in the water to it
ugly to say that water that
stool from those fish that shit from
that contains fish
ammonia what that ammonia that gets through
and that water from those fish is through
a pump inflated
to a bin above it
planter that is filled with argex
grains grains somewhere knows gall him
everything and that little brown clay
grains
sometimes also the houseplants
in it
the water of those fish with the plow the
ring serves as irrigation for those and
guide grains for those plants that are in it
standing and that is feeding with one of
those plants that go at the same time
filter water and clean water runs
back to the fish as such and ge
cycle then you have nothing on
water loss except a little by the
evaporation
how does it work now or what does it look like
in real view this is such a planter
which enjoy growing the fun part
she is also much closer together
put
why because he does not have to fight
for food because there is constant nutrition
so they can be much closer
they are no longer in production
How does it work now in short
fisherman therefore produce waste because he
eating that water gives that dirty
poo is pumped up to the plants
I already said
there are micro-organisms
small bacteria that cause it
actually that the ammonia in it
is converted to nitrites and nitrate
I will not elaborate on it but take it
from me to those nitrates that is ideal
as a plant food
the plants absorb those nitrates
thereby growing and the roots of the
plants that
filter the water so that you are clean
send water back to the fish and their
have closed circuit you like this though
said so is that simple and system
yet in Belgium I still know
but one person who really does that
is
it is still a system in Belgium
little known that sense abroad is there
always something more popular
I would fish
that means you also freeze your own
can grow that division can eat
if you wish
which fish you can bet that it
the most ideal dirty is the tilapia
but 10 why is that the most ideal
dirty because he is on six and nine months
really say slaughter is that you
then can eat
but the disadvantage to tilapia zi
preferably to swim in warmer water
faster growth and thereby and
Belgium certainly if you have such a system outside
put in the garden
yes usually it is not so hot
Belgium would be perfect for example
to be able to deploy a hero that lasts
slightly longer
times he is big and ready to go on
to eat
but for each to lower
temperatures live perfectly in such a
feedback says enough about those poor chips
I’m going there to have ethics to
fish seller
you can of course also just
use goldfish or mccoy
and if we have the other advice or cage
then you obviously think of the
pond that you have light in your garden
are also that pond can perfectly
serve to this system with the
actually make it but there is an extra
dimension
and you often do not see that in it
abroad but with the system
I then saw that my article
write that extra dimension last year
that’s quail
quail which of course is not just meat
but most of all
eggs produce quails that have the
property that they do not bleed much
need that do not have a big one
keeper and needed as the
ordinary chickens that can live in late
we say a kind of rabbit hutch
place that does not need a bit
fresh straw and look that lay every day
Eggs eggs that also happen again
much more nutritious than ordinary type
eggs in a quail egg
tricks about a 10 grams while
the one type and 60 to 70 grams is only to
ratio
there are a lot more vitamin there
abd and e in in such a
quail he is also very easy to
there quails with the cultures themselves
you just have such a lighter time
a brooding box and you have small quarters
after a while
a beautiful one between beautiful systems
extra dimension if you have those quails
village also know that can be natural
but we are not going to be too gruesome here
and we do not go bloody stories
tell about it
look that is the harvest that they are on one
day could fetch if you have such a system
have as you have seen there later
such a planter or two
Planters can make this your daily appearance
are strawberry tomatoes
arjan can root it can manage
peppers can be called cucumber
but on all kinds of lettuce all kinds
spice everything can of course no one
apple tree
the king or his orange tree dani
but the most common vegetables can
there have to grow in such an approach
you can also see that in the background
argex granules and the applications are
huge
this is a photo from indonesia where one
who fishes in channel it is along the
rice fields and the water from that
channels then irrigate the rice
team piece to grow faster than
when that fish would not be one there
in sitting
this is the spice tray you are looking at now
maybe standing in your kitchen somewhere
what is a fishbowl or the
fish goblet that you also have them cake
herbal bath you connect on top of those two
with each other and your herbs grow on the
fish poo another one before you
cracks
you can do it yourself or yourself
for companies, for example
sit next to the coffee machine does not put
candy box
But there is something like that and this is now with
plants but it can be done in such a way
me strawberry plants and leave your
employee there daily a portion
bring strawberries or tomatoes and for
small companies
now go with a show and electrabel
or another big company is then
perhaps difficult to everyone all
days of fresh fresh vegetables too
but for small businesses
this is ideal for your next coffee
and if you have a pond
I have already said that combine with
a square meter
vegetable trays where your own vegetables and
herbs
the possibilities are enormous and this
is the system that I am talking about
written did you see it stood like this
two of those bins with below that
another aquarium or feedback and
that is sufficient for a family of four
people for most of the year
to be self-sufficient in terms of
vegetables in terms of eggs and if you would
also win in terms
meat from the quail’s chickens and
from the dirty if you would like to
ladies and gentlemen I think aquaponics
, and solution to the future
all that food problem and way out
in it
and out of that while will have to be for
I’ll say it another time we are
nearing 10 billion but it is
less water less fertile soil
I think the aquaponics in small piece
of the solution
thank you
