The more you flush, the more you drive | Frank Rogalla | TEDxIEMadrid

good evening I’m Frank and I’m dressed
for the occasion all in green and I’m
gonna talk to you a little bit about my
favorite green stuff is not spinach it’s
not asparagus
it’s algae what happens in your mind you
think about sushi as Johnson just said
you think about the spirulina tablets
maybe you can buy at the health store
actually at my last tell us or therapy
session they gave me some algae shampoo
or even fed me some algae tea so you can
do a lot of good stuff with algae
because it’s actually if you remember
the first organism that appeared on
earth because to grow it close by the
sunshine photosynthesis it only needs
one T’s in the water sunlight little bit
of co2 from the atmosphere and
fertilizer nitrogen and phosphorus
because it has such a simple lifestyle
only three little things it can grow
very very fast the algae can grow fifty
to hundred times faster then corn or
wheat what you eat every day well you
probably think that’s wonderful you can
make love sushi
well actually we all produce fertilizer
and if that fertilizer goes to the water
then algae will grow and the more we go
to the toilet the more we flush the more
algae will grow in the water because
they go so fast and of course in the end
if too much algae grow they also die if
they die they consume oxygen if too much
oxygen is consumed the whole river is
asphyxiated
so that is the problem with too high
growth of algae well then then my job
comes in I’m an environmental engineer I
try to keep the rivers clean the United
Nations gave us 17 commandments for a
better planet to sustainable development
goals I’m the high priest of number six
make clean water and of course once you
have clean water you have a healthier
life
more livable cities and you protect the
aquatic life well that is my job every
day I try to find at a bigger basins to
keep water clean that’s what we do
normally we put water in big basins we
pump in oxygen to clean the water and to
get the fertilizers out back to the
atmosphere nitrogen and co2 so has been
a story of my life thirty years of new
technologies
always using oxygen to prevent algae
growth to make sure no fertilizer goes
into the waters but of course that takes
a tremendous amount of energy all that
oxygen that you blow in actually to
clean up all the wastewater of the five
hundred million people we have in Europe
it takes two nuclear power plants just
to clean the water and as of course we
now talk about sustainability is that
really the right story so ten years ago
I started thinking why am i fighting the
algae maybe I can make them an ally
maybe I can turn them into solution
because they grow so fast they can
actually help me absorbing the
fertilizers if I control them they will
produce oxygen and feed the bacteria
that internally in the water so from
that symbiosis between algae and
bacteria we could get clean water and
protect our rivers and at the same time
we would even produce a lot of biomass a
lot of algae and maybe make something
useful out of it maybe not sushi but you
might not know but the fuel the gasoline
that you pump into your car today is
nothing but algae from hundred millions
of years ago so that is the key convert
algae to energy there’s a lot of oil
companies trying
we thought about a very simple way just
think about the Spanish pronunciation of
algae or gas so we can actually convert
algae once we grow them
trol simple mason we can harvest them
and we can convert them to gas actually
whenever you find oil you find gas
because very easy to convert organic
matter to gas and that is what we have
been working on trying to maximize the
growth of algae in a controlled
environment to produce the best and the
cleanest energy that is methane of
course it took us a few years we started
working with University of Cadiz the
university of Almeria first on
small-scale in the laboratory made sure
we couldn’t control the parameters very
soon we went to a larger scale – so it’s
not only a laboratory animal we can
actually make it work in practice we
went bigger and bigger just so there was
an industrial solution that can help you
fuel cars we actually ran a car for two
years on the exclusive algae methane and
today we can present you the first
large-scale industrial algae biofuel
Factory it’s actually down in Chicana
near Cadiz we built two hectares two
football fields of algae ponds that you
can see here they were actually
inaugurated last December by the
European Commissioner for energy the
young Arrius committee and we’re very
grateful that all these steps were
actually co-financed by the European
Union and today we can show that all it
takes is one football field and maybe
5,000 spectators let’s wash the toilets
that produce the wastewater and then all
the twenty players on the field can have
free fuel for their cars for a year so
you clean the water with five thousand
people’s wastewater and you have twenty
cars that move for free with clean
energy energy at the same time and even
saved all the electricity and other
electricity needs for about twenty
people that will not be consumed because
the algae produce the oxygen how does
that compare to other biofuels you might
know that in Brazil cars work on sugar
ethanol we get some beer diesel from
Malay
from the palm oil well both of those if
we lucky produce 5000 litres per hectare
per year that’s enough to move five cars
with algae we can move four times more
twenty cars per hectare without any
energy input just with the dirty water
not using any arable land just using
waste water and of course with that we
have saved two of the biggest consumers
of energy oxygen for wastewater
treatment and artificial fertilizer
production and in the same time we have
saved a lot of electricity what does it
mean if we want to fuel now all the
world’s cars with algae methane actually
to fuel all the 30 million vehicles we
have in Spain we only need half the size
of Belgium and Belgium fits 4 into 3
times into Andalusia so only 1/6 of
Andalusia is enough to fuel 30 million
cars and with that we can now conclude
the more you flush the more you drive
and I can fulfill my dream take my waste
water pipe put it into my car and drive
off into the sunset and I have also
fulfilled goal number 7 of clean energy
of the United Nations and goal number 13
or for testing the climate thank you
very much [Applause]
