this is waste from making apple and pear
0:03
cider
0:04
it's a mixture of skin pulp and seeds
0:08
after squeezing the juice out about a
0:10
third of the fruit is left over and
0:12
cideries have to figure out what to do
0:14
with it
0:22
an argentine inventor saw a gold mine in
0:24
this group
0:27
jose alberto arenberry found a way to
0:30
turn it into logs that can replace
0:32
firewood and charcoal
0:37
but in a country that's been barbecuing
0:39
for centuries are people willing to
0:41
break up with firewood
0:42
we visited argentina to see how one
0:44
company is using worldwide waste
0:50
three rivers run through alto valley
0:52
creating a patch of fertile ground
0:53
perfect for growing apples and pears
0:56
[Music]
0:57
each year the country's apple cider
0:59
industry alone creates about 75 000
1:02
metric tons of leftovers this fruit
1:04
waste is called pumice and it's the
1:06
heart of jose's business biot
1:09
it all started with a dried piece he
1:11
took home to run some tests on
1:14
cortana
1:21
and
1:26
realized pumice could be used for fires
1:29
but the real challenge was figuring out
1:31
how to turn tons of slushy fruit into
1:33
solid logs
1:44
he had lots to experiment with
1:46
since cider makers like marcelo garcia
1:49
are usually happy to have someone take
1:50
it off their hands
1:53
[Music]
2:03
making this cider starts with fruit that
2:05
would have otherwise gone to waste
2:19
foreign
2:22
on the way to the grinder the fruit
2:23
travels through the factory in channels
2:25
of water
2:28
a belt of buckets lifts the fruit to a
2:30
mill that crushes it
2:33
a processor
2:41
but the pumice can't get too dry or it
2:43
won't move smoothly through the
2:44
machinery
2:46
so the cidery adds water back into the
2:48
mixture
3:00
says the promise has lots of uses like
3:02
composting heating and making vinegar
3:09
[Music]
3:14
the biggest problem is moving the wet
3:16
heavy mixture
3:22
jose gets thomas delivered to his
3:24
property by the truckload
3:47
so far the cheapest option is simply
3:49
dumping thomas on the ground and waiting
3:51
a few days
4:01
then a worker uses a bulldozer to move
4:03
the gunk into a specialized machine
4:11
but
4:22
with the help of a tractor the machine
4:23
dispenses a line of pumice onto the
4:25
ground and slices it into brick shapes
4:41
jose piles up the dry pieces
4:45
he often tries out other systems like
4:47
drying smaller batches in a rectangular
4:49
mold
4:56
the mold could help him make thinner
4:58
bricks that don't need to be flipped
5:07
experiments
5:15
he's considered making other products
5:16
like animal feed but right now he only
5:18
sells the so called bio logs
5:46
[Music]
5:48
jose says their different skills make
5:50
them a good match
6:05
she sells the logs to some local
6:07
businesses and to people who use them at
6:09
home
6:10
traditional argentine barbecues or
6:12
asados date back to the 16th century
6:15
nowadays lots of people use charcoal but
6:18
some say wood gives me the best flavor
6:20
so it's popular with restaurants
6:33
jose says meat grilled with biot doesn't
6:35
taste any different
6:44
it is
6:57
about the same amount of energy as
6:58
regular firewood and burning them has
7:01
about the same effect on air quality
7:04
jose says it costs the same too
7:06
and the business is profitable because
7:08
costs are low
7:10
customers have to come to his farm to
7:12
pick up the product
7:14
yeah
7:17
in 2019 jose and christina supplied the
7:20
local government with biot which gave it
7:22
out to low-income households
7:24
but elections brought in a new
7:25
government that didn't renew the deal
7:27
leaving them with almost 100 metric tons
7:29
of extra inventory
7:31
christina says their current processes
7:33
are slow and difficult to scale up
8:00
no matter what he's proud to leave
8:02
behind a legacy of invention
8:08
important
8:14
[Laughter]
8:28
oh
