Introduction: 31 Unusual Uses for Coconuts

Picture of 31 Unusual Uses for Coconuts

When I was in college, I got a job as a student researcher in my Engineering department. My job was to research coconuts. My professor was trying to find ways to turn coconuts into value-added products. The goal was help promote economic development in countries like Papua New Guinea where coconuts are plentiful but are not fully utilized. We researched all aspects of coconuts and how they can be used. As a result, I gained a lot of random knowledge about coconuts. So I thought that I would share some of the more interesting things with you. Here are some unusual uses or coconuts.

Step 1: Coconut Husks: ​Medium Density Fiber Boards

Picture of Coconut Husks: ​Medium Density Fiber Boards

The husk of a fresh coconut is made of very strong fibers. The material between the fibers has a high lignin content. This lignin can act as a natural glue. All you have to do is shred the coconut husk and press it into a mold. Then heat it up to a few hundred degrees and it will turn into a solid board that is similar to medium density fiber board. You don't need to add any additional glue or filler. It can be made from 100% coconut husk. This can be used for construction just like regular fiber boards. Coconut boards are even being considered for use in car floor boards.

If you are interested in the science behind this process, you can check out the attached pdf of a paper by one of my former research partners Stanton Greer.

Step 2: Coconut Husk: Biodegradable Chairs

Picture of Coconut Husk: Biodegradable Chairs

When the fibers of a coconut husk are combined with a small amount of latex, it can be molded into free form furniture such as this chair. This is cushioned and flexible but still retains its shape.

You can read more about this project here:

Step 3: Coconut Husk: Hydroponic Planting Medium

Picture of Coconut Husk: Hydroponic Planting Medium

Ground up coconut husk is a popular hydroponic planting medium. This is especially popular with growing orchids and mushrooms.

Step 4: Coconut Husk: Rope

Picture of Coconut Husk: Rope

The fibers of the coconut husk can be separated and branded into a very strong rope.

Step 5: Coconut Husk: Erosion Netting

Picture of Coconut Husk: Erosion Netting

The husk of a coconut has long fibers that can easily be woven into ropes and nets. It can be used to cover eroding landscapes help prevent further erosion and to promote plant growth. It then biodegrades without a trace.

Step 6: Coconut Husk: Floor Mats and Rugs

Picture of Coconut Husk: Floor Mats and Rugs

The fibers of a coconut husk can be woven into durable rugs and mat. The course fibers are very popular for door mats.

Step 7: Coconut Husk: Scrubber Brush

Picture of Coconut Husk: Scrubber Brush

The tough fibers of a coconut husk are great for scrubbing away dirt and grime. They make fairly decent scrubbing brushes.

Step 8: Coconut Husk: Armor

Picture of Coconut Husk: Armor

These are examples of a helmet and armor used in the Gilbert Islands in the 1800s. They are made from woven coconut fiber. The fibers are sometimes reinforced with human hair. The helmet is typically about a 1/2 of an inch thick and is said to have been as stiff and sturdy as a strong board of wood.

These are on display at the Fairbanks Museum and Planetarium, St. Johnsbury, Vermont, USA.

Step 9: Coconut Husk: Figurines and Dolls

Picture of Coconut Husk: Figurines and Dolls

The fibers of a coconut husk are long and tough. This makes them very useful for crafts. They can be made into dolls and figures very similar to straw figurines. You can see more about this artist here:

Step 10: Coconut Shell: Activated Carbon

Picture of Coconut Shell: Activated Carbon

Coconut shells are some of the best materials for making activated carbon for filters. Coconut shell are very dense and are covered in micropores that are ideal for trapping small contaminant particles. It is also a cheap renewable material that grows all year round.

Step 11: Coconut Shell: Pet House

Picture of Coconut Shell: Pet House

Coconut shells can be hollowed out and used as houses for small pets like hamsters, birds and hermit crabs.

Step 12: Coconut Shell: Very Uncomfortable Bras

Picture of Coconut Shell: Very Uncomfortable Bras

Coconut shells can also be used to make very uncomfortable bras. All you need to do is cut a coconut shell in half, and put some string on it. Then voila! You have the worlds most impractical bra.

As you may have guessed, coconuts don't usually grow in the same proportions as the human body. So don't expect it to fit, or be comfortable or supportive. This is why they are most often worn by drunken frat guys.

Step 13: Coconut Shell: Sound Effects

Picture of Coconut Shell: Sound Effects

Anyone who has seen Monty Python and the Search for the Holy Grail knows that coconut shells are the best way to make the sound of a galloping horse. If you haven't seen this yet, here it is.

All you have to do is take two halves of a coconut and hit them together. The geniuses at Trotify have even turned this into an attachment for a bicycle that will automatically make the sound of horse feet as you ride along.

Step 14: Coconut Shell: Octopus Armor

The hard shell of a coconut can make an excellent defensive tool. The humble octopus has figured out a way to use it as a kind of armor. It carries coconut shells around with it. Then if it feels threatened, it pulls the shells around itself and hides. This acts as both armor and camouflage.

Step 15: Coconut Water: Sports Drink

Picture of Coconut Water: Sports Drink

The water of a mature coconut has a lot of electrolytes in them that are perfectly balanced for an electrolyte replacement sports drink. It's nature's sports drink.

Step 16: Coconut Water: Jello

Picture of Coconut Water: Jello

The water of a coconut can be fermented to make a jelly like food product called Nata de coco. Nata de coco is most commonly sweetened and served as a candy or dessert.

Step 17: Coconut Water: IV Fluid

Picture of Coconut Water: IV Fluid

Fresh coconut water is sterile and high in electrolytes and it has been used as an emergency replacement for saline in IV's.

Seriously. You can read about it at PubMed:

Step 18: Coconut Water: Natural Diuretic

Picture of Coconut Water: Natural Diuretic

Coconut water is a natural diuretic. So if you are ever in the medical situation where you need a diuretic, just drink some coconut water.

Step 19: Coconut Oil: BioDiesel

Picture of Coconut Oil: BioDiesel

You can actually use coconut oil as fuel in diesel engines. When Rudolf Diesel invented the diesel engine, he actually designed it to work on vegetable oil. But using straight vegetable oil as fuel causes a number of problems with the engine. This is especially true of coconut oil because it has such as high viscosity and melting point. It is even solid at colder temperatures.

The solution is to use a process called transesterification to turn the oil into biodiesel (a fuel that more closely resembles petroleum diesel). You can read a whole instructable on this process here: This makes a fuel that you can put directly into your truck or mix with petroleum diesel in any ratio that you want.

Step 20: Coconut Oil: Sunscreen SPF 4

Picture of Coconut Oil: Sunscreen SPF 4

Coconut oil can be used as a low power sunscreen. If rubbed on the skin it has a sun protection factor (SPF) of about 4 according to This isn't much compared to commercial sunscreens but it is still significantly better than bare skin. If you are ever stuck on a tropical island, you would probably want to use it.

Step 21: Coconut Oil: Vegetable Shortening Replacement

Picture of Coconut Oil: Vegetable Shortening Replacement

Coconut oil can serve as a passable substitute for vegetable shortening in many recipes. Like shortening, it is thick, viscous and solid at room temperature. But unlike shortening, it has no trans-fats (hydrogenated oils). Unfortunately it will melt at a slightly lower temperature than most shortenings. So keeping that in mind, you might want to keep it chilled when using.

Step 22: Coconut Oil: Soap

Picture of Coconut Oil: Soap

Coconut oil like any other fat can be used to make soap.

Step 23: Coconut Oil: Skin Cream

Picture of Coconut Oil: Skin Cream

Coconut oil is often uses as a general skin cream. It is most often used as a basic moisturizer.

Step 24: Coconut Oil: Diaper Cream

Picture of Coconut Oil: Diaper Cream

Coconut oil is often used as a general skin cream and it is even used as a diaper cream. This helps to alleviate some of the symptoms of diaper rash. This is not as effective as products that contain Zinc Oxide. However it has the advantage of being washable. People to use cloth diapers will tell you that zinc oxide paste builds up on cloth diapers and doesn't easily wash out. Coconut oil products on the other hand can be easily cleaned off with regular detergent.

Step 25: Coconut Oil: Sand Flea Repellent

Picture of Coconut Oil: Sand Flea Repellent

Coconut oil is used as a natural repellent for sand fleas (Tunga Penetrans). Just put a thin coat on your skin to help avoid annoying bug bites.

Step 26: Coconut Meat: Protein Supplement

Picture of Coconut Meat: Protein Supplement

The meat from a coconut is very high in protein. After the oil is pressed out, you are left with low fat high protein powder that can be adding other foods as a protein supplement. Coconut meat contains all the essential amino acids that the human body needs. This makes it a great natural source for complete proteins.

Coconut meat is also commonly used as a supplement in cattle feed.

Step 27: Coconut Meat: Flour

Picture of Coconut Meat: Flour

After the oil has been extracted from the coconut meat, you are left with a fine powder that is used as a substitute for flour in many forms of cooking. It is widely used by those who are trying to avoid gluten.

Step 28: Coconut Meat: Self Frying Chips

Picture of Coconut Meat: Self Frying Chips

The meat from a coconut can be sliced or shredded or shaved. The resulting thin pieces of coconut can be baked or microwaved. The oil in the coconut fries the coconut like a potato chip but with no need for a fryer. Just add salt and enjoy.

Step 29: Coconut Milk: Dairy Substitute

Picture of Coconut Milk: Dairy Substitute

Coconut milk is a mixture of coconut water and coconut meat (usually taken from a young coconut). This can be used as a dairy substitute. You can drink it like milk or you can cook with it. It is commonly used to make non-dairy foods like ice cream.

Step 30: Coconut Tree Sap: Sugar

Picture of Coconut Tree Sap: Sugar

If the young buds of a coconut tree are cut, they will start to drip a sugary sap similar to maple sap. This can be collected in jugs. The sap is them purified and boiled to make coconut sugar or nectar. This has a distinctive flavor and can be used as a substitute for regular cane sugar in any recipe.

Step 31: Other: Tourist Population Control

Picture of Other: Tourist Population Control

A coconut tree can grow to over 50 feet tall and a coconut can weigh up to 10 pounds. Needless to say, falling coconuts can kill you. Anyone who grows up around coconut trees know that you don't hang out under a tree full of ripe coconuts. But tourists are not always so wise. So signs are posted everywhere. Trees in heavily populated areas have the coconuts removed. But still, coconuts kill a lot of people every year.

Something else interesting-There are groups out there that harvest coconut shells and turn them into a very efficient charcoal.

juntjoo (author)2016-08-25

I have four tall coconut trees and when they fall it sounds like a natural disaster or something happening outside. When I mow the lawn outside under them I ar least hold a hand over my head. I figure the chance is slim but I dont want to take it

AngelP1 (author)juntjoo2016-09-16

I also fear of a falling coconut when i mow my aunts lawn. I always try to take them down or keep an ear just in case but a helmet is the best option now that i think about it.

thundrepance (author)2016-07-08

FANTASTIC ideas! thank-you for sharing!! :^D

Amnesia Wes (author)2016-07-06

My dog, Yobo, likes to tear apart coconuts after they've fallen from the tree and dried a bit. The shredding fibers act as dental floss, naturally cleaning her teeth beautifully.

Brian 1968 (author)2016-07-03

coconut oil is also very good as part of a wood polish. I melt pure beeswax, add coconut oil. When it melts clear, take off the heat (an old pan in another pan of boiling water) then add olive oil and pour into an old jar and allow to cool. It takes a couple of goes to estimate the quantities. The polish should be easy to wipe out of the jar with a soft cloth, though I find it easier with my fingers. Rub liberally onto the sanded wood surfaces, allow to soak in in a warmish room for about an hour and polish, beautiful.

Ninzerbean (author)Brian 19682016-07-04

I do the same thing, mixed up a batch 3 years ago and it's wonderful, no petrol chemicals. I like to heat up the wood in the oven first for easier penetration.

Brian 1968 (author)Ninzerbean2016-07-05

heat the wood sounds like a good idea. Do you apply the polish while the wood is hot? How hot should the wood be and does it vary on which wood it is? Bet you wish you hadn't mentioned it!!

Ninzerbean (author)Brian 19682016-07-05

I heat up the oven to 170F which on my oven is as low as it goes, I do this for metal stuff as well, same temp. I use driftwood cedar that I dye. The photos show different ways that I heat the coconut oil mix, melt off the excess with a heat gun, and apply it to heated wood. Just depends on how many I have to do as to which technique I will use.

JohnG220 (author)2016-07-05

Very interesting posting, thanks! One point, where I have to be a grammar-Nazi, step six should be coarse not course.

japneet singh (author)2016-07-04

Thanks Ithica now I do understand the meaning of protein and nutrition bars.Thanks for your valuable guidance.I will try my best If I could prepare it at home.


GayleneO1 (author)japneet singh2016-07-05

see my reply below to Dennis T33. You could pretty easily do this. Best of luck! Hope your injury heals quickly :)

DennisT33 (author)2016-07-03

For those with an abundance of coco waste, one word: biochar

#32 save the planet

GayleneO1 (author)DennisT332016-07-05

Excellent point! Bio char is easily made with many materials, but coconut husk is a perfect medium for this because of its porosity. Easily exported in bags, and readily usable on a small or large scale farming or gardening operation. Also easily turned into activated charcoal by adding the next step, then creating filters for areas suffering impure water sources. japneet singh, you might look into this. Small scale, heat over a fire in a large tin with a few holes poked into it. Look for the instructable on how to make your own charcoal, and you will have the beginnings of an easy to do business!

AnnabellaMarie (author)2016-07-05

I use coconut oil in/on everything. Sauteed onions....scrumptious. Oatmeal... I enjoyed this info very much. And I'd like to mention that fresh coconut water is nearly identical to breast milk and has been used when necessary.

LaurieH2 (author)2016-07-04

Another use of a cleaned out, half of a coconut shell is to stretch your plantar fascia muscle on the bottom of your foot. Put the 1/2 shell on the floor, cut side down, and step on it, manipulating your foot and how much weight you place on it til you feel the stretch. .

KarenW50 (author)2016-07-04

If any of yu want to try any of this, I currently have 42 coconuts growing on the tree in my yard. You just have to come get them. Oh, did I mention they are 25 feet in the air?

LaurieH2 (author)KarenW502016-07-04

Karenw50 - I hope you are being careful and avoiding the falling coconuts! This was an informative, yet funny article. I love coconuts but it's hard to get a good one in the supermarket here in Indiana!

Ronald Howard (author)2016-07-04

The coconut husks are used to make an erosion control fabric.

CaroE1 (author)2016-07-04

Ah I love the cycle attachment..are they available on a well known website? I guess it could get a bit noisy if everyone had one...

As someone who got hit by small child on a bike it could provide a good early warning system though..I still panic after a year and wish they all had little bells to gently alert you from behind!

japneet singh (author)2016-07-03

Hi I am 57 yrs old chef and now unemployed due to mild fracture on the spinal cord disc.You have given me a new hope by yr research on coconuts waste.Can you suggest me a small project which I can start at home and earn my bread and butter and also could send products for exports if I succeed.

As a chief try creating a food bar/nutrition bar/protein bar that is cheap taste good and does not contain large quintiles of sugar.

japneet singh (author)ithica20122016-07-04

Hi Ithica thanks for your valuable guidance.I understand being a Chef but space is required for bars etc which is very expensive in India and also need lot of finance.I just desire to do something from my home.As I am without job from 10 months reason being had a mild fracture on the spinal cord disc for which I was unable to sit,stand and sleep for long time.

Regards Johnny from New Delhi,India

dmuchu (author)japneet singh2016-07-04

I guess you misunderstood ithica2012's meaning of bar in "food bar". The meaning that he uses is this: "a solidblock of a substance such as chocolate or soap

a chocolate bar

bar of:

a bar of soap"

You seem to be using another meaning of bar which is: "a place that servesfood

a sushi bar

a sandwich bar"

I think the most money is made with the sale of pet products made from coconut shell.

You will find very expensive toys made from coconuts for pets like parrots on-line.

This one is sold on ebay for £22 !!!!!

wow! What a lot of terrific information! Thank you! :)

LynB9 (author)2016-07-04

In the Caribbean, the coconut shells are also used to make costume jewelry, even painted on. The coconut shell is also used to make containers and drinking cups complete with its own stand. These are usually etched with designs and coloured.

pskvorc (author)2016-07-03

Let's see: Use for intravenous hydration or oral diuretic. Hunh???

By the way, if coconut 'water' is sterile, how can it ferment IN the nut? Must be some of that spontaneous generation stuff of the 19th century.

There are some interesting ideas in this instructable, (I like #1), but there are a couple that make me say "hunh?".


LynB9 (author)pskvorc2016-07-04

You would have to be living in the tropics to know the FULL potential of coconut water and the other uses of the coconut. Although each tropical country/island uses the coconut differently. As the nut gets older, and the meat gets thicker, the water does ferment in the nut, that it is undrinkable. Fresh coconut water is what is used as a sports drink, and also as an intravenous liquid. Coconut milk and oil are made from the coconut meat. Personally, I like the coconut water when the meat is a little thicker, and the fermentation is at an early stage - that is when the water begins its slightly fizzy stage - delicious!!

japneet singh (author)2016-07-04

Hi ithica thanks for your valuable guidance.I will definately try.


OscarD6 (author)2016-07-03

Excellent compilation! I live in South India, and see a lot of coconut in daily use - its abundantly available and grown all over!. One of my favourite uses is a maraca (a percussion musical instrument with seeds inside), and also as the common-man's liquor (coconut fenny from Goa, India :)

HazelL2 (author)2016-07-03

I once saw the hood of a truck get destroyed after the guy parked it in the shade of coconut tree. It only took one coconut too. Lovely and cool inside - but whole new hood required. You win some, you lose some I suppose.

How does cocunut repeail fleas

Gadget93 (author)2015-07-06

Great instructable. I didn't realize half this stuff. I didn't realize that people get killed from those things in trees.

ithica2012 (author)Gadget932016-07-03

The same thing happens with Brazil nuts.

LDM1 (author)2016-07-03

I read that 150 die per year from falling coconuts.

If a guy could get his hands on some millstones you could probably grind the shells like they mill flour then make a variety of things like they have displayed on this site. Here in the U.S. I don't know how easy it would be to come by coconut shells though.

SteveB174 (author)2016-07-03

Nice but most require technology to apply. Meanwhile, the coconut tree and nut have so many uses that are not listed here and require virtually no complicated processing: for making a fire, all parts of the tree and nut are unparalleled, providing tinder, kindling, and fuel: a dry empty coconut including husk will burn hot and long. The meat was mentioned but is an excellent food source. In Central America, they cut a dry coconut incl. husk crosswise (at the equator) and use the rough fibrous surface to polish tile floors or any hard surface.

bruno13069 (author)2016-07-03

Sounds like you are on your way to be the George Washington Carver of the coconut! Nice I-bile!

Alexaluvu (author)2016-07-03

This is actually really cool, I didn't realize how many things you can do with coconuts! But now I know!

Thank You!

NurmanA1 (author)2016-06-10

What about the young coconut waste utilization ? because in my country many young head of waste that can not be utilized . tanks.

ithica2012 (author)NurmanA12016-07-03

Have you thought about converting it to charcoal then taking it and mixing it with say cassava or other binding agent and making charcoal briquettes you can also mix the charcoal (biochar) into the soil to improve it. Charcoal making requires little in the way of equipment.

That is one of the problems. In a lot of countries there so many coconuts that go unused that they become an agricultural wastet that needs to be dealt with. There just needs to be a system in place to process them into valuable product.s

It seems to me that many of these countries have very poor soil (basically just sand) so if they they added the the coir (the hairy outside part of the shell) to the soil they could soon grow more valuable products like sugar to make rum or wheat to make 'summer' style beer.

May need a technology that can develop young coconut shell waste into a value more or mingkin alternative energy sources. If there who can create that is an appreciation of its own and certainly in some countries can adopt these technologies.

I use a four stroke 2 wheeler for my transportation .The mileage claimed by the company is in plus or minus49 .Once in a year I mix 20ml of coconut oil with 5liters of petrol(in petrol tank). The mileage increases. I dont no what causes the increase in mileage to55km/pl. Can anyone explain this?

TonyW87 (author)2016-07-03

What is the best, low-tech, way to shred the coconut husks?

...and don't try to remove the husks from a mature coconut with a knife (it's hard work, even with softer, immature nuts!) - the best way is to use a metal spike in the ground - a piece of scrap Y-12 re-bar works (sharpen a chisel point with a grinder, or just bash with a big hammer)
