1
These pineapple leaves used to be worthless.
2
But about a decade ago,
3
a designer revived a centuries-old technique to extract fibers from the fruit.
4
She used it to create a convincing alternative to leather and a new type of yarn.
5
Then we've got this, which is really a metallic.
6
It's quite flashy.
7
Fashion people love it.
8
Pineapple is more popular than ever.
9
The crop grows on over 3,800 square miles worldwide,
10
enough to cover New York City ten times over.
11
But about half of every fruit ends up as waste.
12
Carmen Ijosa wants to convince growers they can turn a profit from their leftovers.
13
It's really the queen of fibers.
14
Famous brands like Nike already use her product, called Piñatex.
15
And Carmen is not alone.
16
Entrepreneurs in other parts of the world are making money from pineapple scraps.
17
Here are three companies turning the fruit into textiles,
18
disposable plates, and eco-friendly cleaners.
19
The idea for textiles made from pineapples is nothing new.
20
It actually dates back to the 1500s.
21
Pineapples come from South America,
22
but once they made their way to Europe,
23
the fruit became a status symbol,
24
gifted to royalty, like King Charles II and Spanish King Ferdinand II.
25
The Spanish brought the fruit to the Philippines,
26
where locals turned it into a fabric called piña.
27
It was mainly used to make Barong Tagalog a traditional formal shirt.
28
That centuries-old technique inspired Carmen when she first heard about it 30 years ago.
29
I was working with leather at the time,
30
but I realized the unsustainability of the leather manufacturing processes,
31
and I discovered natural fibers.
32
Pineapple leaves turned out to have the perfect mix of strength and flexibility,
33
and they can grow up to six feet long.
34
That gave me the idea of what if I make a mesh not unlike what leather is.
35
She spent decades perfecting her process before she launched her company,
36
Ananas Anam, in 2016.
37
At the start, it was really like, what are you doing?
38
You know, why not keep using leather?
39
Her research resulted in two different products.
40
Piñatex, which mimics the qualities of animal leather,
41
and Piñayarn, a replacement for yarn.
42
I'm what you can call a serial entrepreneur.
43
Ananas Anam partners with the Dole Sunshine Company and independent farmers to employ over 500 people.
44
Workers harvest pineapple leaves that would otherwise be burned or left to rot,
45
and run them through a machine that extracts the fibers.
46
The sun dries and browns them in just a few hours.
47
The fibers are then shipped to Barcelona to become piña yarn.
48
This machine acts like a guillotine,
49
chopping the longer strands into manageable pieces.
50
A carding machine straightens the fibers,
51
then grinds them until they resemble cotton.
52
The baler compacts the mass into tight squares.
53
The fibers are then transported to Portugal,
54
where they're spun into the final product.
55
To make piñatex, a needle-punching machine knits those same ground fibers with threads made from cornstarch.
56
The result is a thick fabric.
57
The sheet passes through a 30-meter long conveyor belt to be dyed and dried.
58
A resin made from plants and petroleum is used for color and adds durability.
59
Then a heated roller flattens the textile and dries the resin.
60
The company says it's working to make Piñatex entirely plant-based.
61
Piñatex is 95% made from renewable resources,
62
so we've got a 5% to work on.
63
square meter of piñatex uses around 16 pineapple plants worth of leaves.
64
The company says it saves 825 tons of leaves from being burned each year.
65
Ananas Anam sells its products to big brands like Nike and Hugo Boss,
66
along with smaller companies that make notepads, backpacks, and handbags.
67
Ijosa says she plans to explore other textile alternatives in the future.
68
I'm here in Spain and I'm already looking at what is being used traditionally.
69
So come back to me in two years' time and I will answer this question."
70
Pineapple leaves might be good for making textiles,
71
but what about the rest of the fruit?
72
In Colombia, a company called LifePak shreds pineapple crowns to make compostable plates.
73
The mixture is blended with recycled paper and turned into sheets that are left out to dry under the sun.
74
A machine presses the sheets into form.
75
If these disposable plates end up in a place with soil and water,
76
tiny seeds inside will blossom in just a few days.
77
On a busy day, workers at LifePak can churn out 10,000 eco-friendly plates.
78
In addition to plates, the company also makes sandwich containers and coffee cup sleeves that contain seeds from edible plants like cilantro,
79
amaranth, and strawberry.
80
LifePak caps its own carbon footprint by working with local suppliers.
81
To make our paper and paper, we don't cut trees.
82
And that's an essential factor because we let 16 trees cut each ton of product made by us.
83
resources pineapple waste from a nearby processing plant.
84
The plant's owners charge nothing for the pineapple crowns.
85
They're happy that someone is willing to turn their waste into a resource.
86
Husband and wife team Claudia Barona and Andres Benevides founded LifePak 12 years ago in in the city of Cali.
87
The couple has won several small business awards,
88
and they even appeared on the Colombian version of Shark Tank.
89
Colombia, like nearly every country in the world,
90
is trying to reduce plastic waste.
91
In 2017, the country introduced a tax on single-use plastics that increases each year.
92
And in some cities, informal pickers are now paid as municipal workers.
93
But getting consumers to buy these products isn't easy.
94
The LifePak plates retail at about $2.50 per dozen.
95
That's more than double the price of plastic plates from a big box store.
96
Despite their higher price point,
97
LifePak has been able to capitalize on growing demand for sustainable packaging,
98
which has increased by 40% since the company started.
99
Its plates are now sold in three large supermarket chains domestically.
100
The company also handles dozens of orders through its website each week,
101
with a handful of customers in the U.S.
102
We could make about 6,000 and 12,000 plates.
103
In fact, right now there's more demand than offer, so we're oversold.
104
That means that the answer to the client is positive and that the product has a market.
105
Lifepak's next challenge is to modernize its equipment so it can boost production.
106
Andres and Claudia also plan to franchise the business and expand into new countries to help more people cut back on plastic,
107
one plate at a time.
108
Even if you don't eat off of pineapple plates,
109
you can still use the fruit to do the dishes.
110
In Vietnam, one company uses pineapple peels and cores to make natural soaps and detergents.
111
The founder, Le Duy Hoang,
112
says they're safer for the planet and people.
113
So safe, he drinks the stuff every day.
114
We can eat the fruit.
115
Fermented fruit is part of a new trend.
116
Cleaning with enzymes instead of harsh chemicals.
117
Does it actually work?
118
Throughout history, people have used all sorts of stuff to wash up.
119
Everything from animal fat to human urine.
120
In the early 20th century,
121
scientists figured out how to make suds in a lab using fossil fuels.
122
That paved the way for all kinds of synthetic gels,
123
powders, and cleaning chemicals, which are all detergents.
124
So much whiter, she can actually see the difference instantly.
125
The problem is, they were full of stuff that water treatment plants weren't built to clean out,
126
like phosphorus and nitrogen.
127
When those elements flood waterways,
128
they can make algae grow faster,
129
creating thick layers of muck that suffocate life below.
130
That's exactly what happened in North America in the 1960s.
131
Lake Erie is almost biologically dead.
132
Today, detergent pollution has spread around the world,
133
foaming up rivers and fueling overgrown algae.
134
Fuwa Biotech is betting that fruit cleaners are the next chapter for cleaning products.
135
The name Fuwa comes from the phrase fruit warrior.
136
The company buys fruit waste from a factory that makes canned pineapple.
137
Workers here chop thousands of them every day.
138
This pile is from just a half day's work.
139
These used to rot in nearby landfills,
140
creating bad smells and methane, a powerful planet-warming gas.
141
Now, workers load the scraps onto a truck and travel about two miles to the production site.
142
Here, the team unloads the fruit skins and washes them.
143
Next, they mix together the first ingredients, sugar and water.
144
Fuwa uses about two metric tons of sugar every month.
145
I eat for the food and the food.
146
So if there's no road,
147
I can't go to the menu.
148
Workers add the pineapple peels to the sugar water and wait for the mixture to start to ferment.
149
Fermentation is when microbes, like bacteria or yeast,
150
break down complex molecules like sugar into simpler stuff like alcohol.
151
It's how barley becomes beer and grapes become wine.
152
At Fuwa, fermentation is how waste becomes cleaning fluids.
153
But the secret isn't alcohol.
154
It's the enzymes and acids the pineapples will release.
155
Enzymes are molecules that speed up chemical reactions,
156
like digestion in the human body.
157
Certain enzymes can fight germs by entering cells and breaking them apart from the inside.
158
This can either kill bacteria or just slow them down enough that they probably won't make you sick.
159
But to make those germs stopping enzymes from plants,
160
you have to ferment the right mix of ingredients for just the right amount of time.
161
Workers here stir the mixture every day.
162
After about a month, it looks like this.
163
It has a smell of smell.
164
It's very sweet.
165
By two months, this glob of bacteria and microorganisms forms.
166
That's how you know it's working.
167
The founders don't keep any of their process a secret.
168
This is 10 parts of the water.
169
10 parts of the water,
170
1 part of the water,
171
and 3 parts of the water.
172
Huang says he learned this technique from Rochocon Pumpanbong.
173
She's a scientist and Buddhist nun who figured out the formula,
174
then shared it freely for others to use.
175
After the mixture ferments for 3 months,
176
there's enough acid and enzymes for it to work as a cleaner.
177
Now it's ready to be filtered.
178
The leftover solids become fertilizer for nearby farms.
179
And the remaining liquid is the base for everything Fu Wah makes.
180
Fu Wah buys those oils from local farmers,
181
who make them using agricultural waste like stems and leaves.
182
The final mixture is bottled and shipped to mini-marts around Vietnam,
183
or to online customers in most countries.
184
One bottle of dish soap sells for just over $2.
185
Huang says that's less than the cost of similar imported products.
186
Phu Hoa uses an on-site lab to test its products.
187
And it looks at competitor stuff as well,
188
measuring the pH and testing for other additives.
189
Cleaning with fermented fruit is a fairly new concept,
190
but there's evidence it has a lot of potential.
191
Researchers compared a pineapple enzyme mixture to bleach and water and found it killed one type of bacteria equally well.
192
And early research suggests fruit enzymes might even make wastewater cleaner.
193
We know more about common chemical cleaners like bleach.
194
They kill lots of germs,
195
but come with other risks.
196
Huang started making fruit cleaners when his wife,
197
now the company's CEO, developed eczema.
198
One reason is to use the cleaning products.
199
Studies have linked cleaning products to skin irritation and breathing problems, including asthma.
200
When used and stored properly,
201
they're safe for most people.
202
But mixing bleach with the wrong cleaners can create deadly gas,
203
which happens thousands of times per year in the United States.
204
So, could we one day replace household bleach and detergents with fermented pineapples?
205
asked an expert.
206
You'll be surprised.
207
Yes, totally yes.
208
But he also said we need more research.
209
There's only a certain number of bacteria that has been tested,
210
so probably got to do a wide range of studies with a wide range of microorganisms to ensure that it's really effective.
211
Enzyme cleaners pose another challenge, shelf life.
212
It will be one of the major issues.
213
With certain temperature, it might be inactivated.
214
Fuwa says its products can last about two years,
215
which is about as long as most chemical cleaning sprays.
216
Still, Fuwa has more work to do.
217
With so much pineapple processing in the region,
218
the company says it has lots of waste to work with.
219
But mainly, the founders want people to know there's a gentler alternative.
220
the ecosystem.
221
So they're eager to spread the word.
