- Scientists in London are testing a form of concrete called sugarcrete which is made from fibrous material left over from the harvest of sugarcane. The material can be made simply and hopes to provide an alternative to high-energy use construction materials.

#sugarcane #concrete #nbcnewsnow
missed the century old news about hemp?
Only thing that matters....is it cheaper?
they said it can be made in rural countries using sugar cane and unskilled labor. So you could make it yourself but depends on price of sugar cane. That being said I can get cinder blocks at Home Depot for about $1-$3 a block.
they avoided to tell what are they mixing the fibers with, but at 0:53 it looked like a clear viscous liquid which to me looks like a resin. So I really don't think it's cheap
Also there is a sand shortage which makes concrete less feasible moving forward.
A lot of renewable from waste can be done for this purpose. While sugar bagasse is abundant in mills, another material is the coconut fiber or palm fiber from the husk that is set aside after copra meat is extracted from fruit.Another abundant material is the fiber from bamboo that is high in tensile strength and can be farmed with less tedious care and cost.
Look at the screen on his test, it failed at 0.125MPA. concrete is way stronger 25-50MPA.
This is a replacement for mud or thatch huts, not modern buildings.
“That’s sweet”
I see what you did there
"Sugarcrete allows moisture and vapor to transfer through it, meaning no mold" (2:04). That's gonna be a hard sell.
Maybe not in the climates where sugar cane is grown.
I doubt they'll be trying to build Manhattan skyscrapers out of it..
We can also create concrete out of hemp fibers. It’s called hempcrete and now that weed will be decriminalized on federal level soon hemp farmers won’t be harassed with anymore annoying drug enforcement regulations. Hemp can also be used as biofuel in diesel engines.
Fun Fact, No one asked you.
… and easy to catch arsonists who sit downwind from the crime scene …
Very interesting, similar to Hempcrete.
One question, can it be used in earthquake prone areas?
Old constructions in my home country were made with a mix of mud and natural fibers. Earthquakes destroyed all that!
how is it made?
Can you eat it? Modern day reporting!
came here to say the same thing. this host is a joke
It's mixed with sand, of course not.
@@sneat2028 yeah we know. that's why we're making fun of the host
My question is, is it Vernon resistant, fire resistant and strong in high wind conditions, also do you need to install a metal or timber frame so as to pitch the roofing frame, and what about the plumbing and electrical installation, how would you install them in the walls
This is a replacement for mud or thatch huts, not modern buildings.
You're making sugar breaks. it looks like it's still bonded together with concrete.
(edit) breaks? bricks
@@punapeter it's fine ok
@@Grant918Tulsa what is?
“can you eat it? I don’t think I will taste very good …” I bet *ants* will digress…
Does sugarcrete provide the hvac and insulation dividends similar to that of hempcrete already being used in parts of the US?
Same question in regards to whether or not sugarcrete is more flame retardant, fire proof?
Not sure why they're so stubborn on using Hemp, uses less water than sugar cane too
My question would be are the cane fibers used a byproduct of sugar production or in addition to sugar production? Theoretically the waste product would have to be broken down and decompose into carbon emissions. So if this is wasted material being used it in effect is stored carbon. An added benefit.
In my country, we use bagasse to make organic compost which is better than the farms only using chemical fertilizers
Can you eat it? I doubt I ever heard a more stupid question from a news commentator.
sugarcrete can attract molds in cold climates.
There are so many natural materials that can replace concrete and many high VOC materials that we currently use in construction. In areas where sugar cane is already grown, this would provide a cheap, readily available alternative and economic benefit to the local economy. In other areas, bamboo might be the material of choice, or hemp, or sustainably grow lumber. All of these can replace a significant amount of concrete, reducing emissions and even act to lock away carbon. Better for the environment and for the people living in the buildings.
A variant of hempcrete.
If using resin to bind, wouldn't carbon fiber be better for strength and if so why isn't there a carbon fiber house too costly
They are trying to re-purpose waste by-product.
Where are the details, this is bagasse Crete rather than hemp Crete, nothing to see here. Add some cement and water to a hay bale and press, hey!
How does it do in a flood or fire?
Hempcrete does the job better & more cost effective.
I have news for you if you think you are going to slow the use of concrete. The oil companies will hire mercenaries to come directly to your front door.
Is it a good idea removing so much biomass from the fields. Fertility goes into bricks, another insane idea of human mankind.
"Pumping 4 billion tons of carbon dioxide into the air EVERY DAY"?? That can't be so, tell me some one.
Is the school building using mortar or a sugarcrete alternative?
peanutbutter
Made a school of sugarcrete blocks and used concrete to bond those blocks lol
Most certainly not scalable. Global cement production is 4Gton per year. When mixed in with sand, rocks and water the weight reaches about 25 Gton per year. Global wugar cane production is 1.8Gton per year, after extracting sugar and drying it remains 0.2Gton.
So it can roughly replace order 1-3 percent of existing concrete flux, assuming ALL of it gets used. There are alternative uses such as biochar. The type of reached conducted in this large "sustainability centers" are absolutely misinformed.
I imagine AI will be used to find even better and more economical alternatives that are carbon neutral or negative.
Can it be 3d printed?
Dumb
I can't hear a word with that noise
I really like being positive but this one isn't so convincing. They conveniently forgot to mention the high risks involved in case of fire. It will be like living in a house made of hay.
Good idea if it doesn't break down quickly
If it's traditional housing , absolutely I will concur
what, sugar, traditional?
What is the woman's name again? How do you say it?
Calling all termites, dinner is served. Yummy
Fantastic!
As per usual, the commentary is less than insightful or useful. It's bad enough the format of the story is simplistic but the commentary shows a complete lack of understanding of any issues. Ancient mud bricks used straw as a binder. With sun drying these bricks still form the ancient foundations of ruins in places like Mesopotamia (Iraq/Kuwait). This isn't a high tech material but useful for local small low rise builds to keep money in the local economy and to provide local building material and enterprise. Modern steel reinforced concrete uses steel, even though it rusts, because it has the same expansion and contraction rate as the concrete. In the west, CO2 injection into concrete make harder concrete through the formation of calcium carbonate. A fast look has this material having 2.5 times the compressive strength of hempcrete bricks. Uses an available byproduct. The other materials other than bagasse, seem to be lime, clay, sand, water and calcium carbonate.
Amazing!😊
I love it!
Let’s trade asbestosis for bagasosis. No thanks.
Awesome
Judging by some of the comments some viewers have wasted their time.
What about the pest?
How many pests eat sugarcane after growth? None! Pests are only harmful to sugarcane during the early stages of growth.
Great science-project work if you can get it.
Such a superficial fluff piece.
use hemp!!!
seriously, 4 crops a year vs one
aloha
Use both!
@@punapeter and better everything ✌️
I’m sorry but the news anchor who asked if it can be eaten.. Is SO SILLY to ask that !! though.. You can eat sugar cane , also you can drink a very refreshing sugar cane hice . like in Honduras 🇭🇳 there’s production of sugar cane!
Is it fire resistant?
🙄
Or we could introduce limestone pebbles into cement. Just as strong as this idea and when the concrete cracks the limestone fills the cracks back in. Centuries old method - But then again, none of this is about saving the planet, it’s all about money.
UNTILL there’s a fire 🔥
stupid background noise i could;nt hear them.
See your doctor...You have a problem.
I wonder how this sugar-crete holds up to moisture, rodents, and insects....
Considering cockroaches eat glue in stuff like particle board/plywood and other things....
Just saying....house crumble under you, or be eaten from under you lolol
and earthquakes, tornadoes, floods, wild fire? BOOM
American houses are literally made out of cardboard
@RahimullahMassom Actually live in a house made of brick over 100years old thank you very much.
Houses vary wildly in the u.s. between materials designs and or quality.
@@RahimullahMassom LOL you live on the sidewalk in a box? LOL
@@LastAyleidKing it's a new troll account, no knowledge, Joined Apr 20, 2024
Any pest infestation study on it?
rats will love it
Sugar is flammable. Hempcreat isn't.
I bet it burns well. And when it floods it melts away. LOL
Just like the homes made here in the USA useless wooden homes LOL
@@DavidJoe-tc1gn Depeneds on who builds them. There are American homes/cities built in the 1700's, 1800's. Even been to Savannah? NOLA? Before new orleans was American is was French and Spanish.
Depends WHERE in america and who's paying.
Why don't you conduct your own study, and get back to us. Your comment is silly.
"CREATOR OF THE UNIVERSE, LORD GOD, I beg you to never force me to worship any false god and I ask you for forgiveness for my sins and immorality. Thank you for everything. Amen."
Please pray this now, pray the words as you read them if you cannot look and remember them 🙏☺
🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Please worship the CREATOR OF THE UNIVERSE, THE LORD GOD and try not to worry too much about the differences between the different religions and denominations, try to think about the similarities and the things they may have in common more than the differences. Daily prayer is a fundamental part that many people do not practice although it is encouraged
Does that make sense? Smh , let us know publically and legally that , whatever building or house is made of that , we have the option not to enter
Rebuild Gaza
😂😂😂 American diabetes association is crying and why USA has eaten buildings
Good way to melt your house away
what about animals eating it? Rats? insects? no cuz it's "treated" chemically? LOL I'll stick to old world skilled building. Not third world.
Is cardboard American houses first world I think not. In other country's houses are made of dried mud and grasses and they last for thousands of years and are eco friendly
@@RahimullahMassom LOL Mud hut? Well I think granite and marble last longer Jabba da hut trollmullah. "Thousands of year old mud huts? Sure, re-mud every monsoon? Eco-friendly?
Why don't you just live in a cave? THEY last millenniums.
What third world country are you stuck in kid.
Look your NEW troll account is almost a month old.

Young men from China. Military age are coming across our border, by the thousands every week. Someday you will wake up and know why. We need Trump to save America.
NBC News make a story with hempcrete concrete made of weed
Republicans fault
Did they forget the existence of termites? The sugar-creet is 100% cellulose! Termite would have a party of all parties! A big pass for me.
Simple addition of a chemical repellant. Not difficult.
