my fatass thought she was holding a chocolate bar in her left hand
Drooling in Homer Simpson
Inside, or in the language of homer simpson?
Homer? I hardly know her
It's ancient Greek writer
Quite good. Very well!
I remember chocolate...
My illiterate ass thought it was a notebook
It looks like unfinished copper like no grinding or finishing touches on the final product. I could be wrong though.
Great product though hope she's making bank!
Life is like a box of chocolates.
I don't have any
better then the post

In 2017, Nzambi Matee, a Kenyan materials engineer, founded her own company to help tackle plastic pollution in Nairobi.
She single-handedly designed the machines for her factory, and has recycled about 20 tons of plastic waste since the founding of Gjenger Makers. Nzambi’s factory produces 1,500 durable bricks per day from a mix of different kinds of plastic.
Nzambi gets plastic waste from packaging factories for free but pays for the plastics from recyclers. “Our product is almost five to seven times stronger than concrete,” Nzambi commented. “There is that waste they cannot process anymore; they cannot recycle. That is what we get.”
She plans to add another, bigger, production line which will triple the capacity of the daily production. The cost of a common grey brick is 850 Kenyan shillings ($7.70) per meter squared.

Ok but please tell us more about the bricks
So after a long and hard google search I came here to tell you that allegedly these bricks are made with 4 outer corners
It mustve been a sick ostrich.
Folks'll say it takes two people to fuck an ostrich.
Ok... dary.... Dary... Ok....
Unusual. Most bricks come with 8 corners.
But only 6 sides. It makes no sense.
While an octahedron comes with 8 sides and 6 corners
As maddening as buying hotdogs and buns.
6 sides too!
and made of recycled plastic
There are even some who claim that they possess 5-7 times the strength of an ordinary concrete brick!
So like a sheet of paper!
So like a walkman?
A real brick would have 8 outer corners, clearly this is a scam.
heheehhe “long and hard”
Wouldnt there be 8 corners ? And 6 sides ?
Weird, all my cuboids have 8 corners vertices.
Hmmm, they don’t look like tetrahedrons.
They very well may break down into micro-plastics that get into the food chain, just like plastic litter.
Yeah, I'd say so. But it's plastic that already exists, so it was going to do that whether it got repurposed first or not.
Maybe, maybe not. Last I checked, there was some debate as to whether it's worse to have the micro plastics in the food chain or the carbon/byproducts of burning or converting the plastics into other fuels, but I tend to come down on the side of preferring to deal with the GHGs than poisoning the food chain. Of course, this area may not have advanced plastic refining/burning plants available for this purpose Soo... Idk
Pyrolysising is very interesting to me. I'm interested in the recycling of circuit boards with a hammer mill. 1 ton (2,000lbs) circuit boards would yield roughly: 500lbs copper, 2-11oz gold, trace amounts PGM's and roughly 1,500lbs fiberglass powder. Could be turned into fuel though with pyrolysis, all the fiberglass.
That waste plastic is (should be, anyway) sequestered in a landfill with runoff control. These bricks would be used...well, anywhere, and the plastic is more likely to run into drains and such.
I hope you didn't type that on a device with plastic parts.
EDIT: Why is it the only time, anywhere, that I see people complain about a product being made out of plastic is these, specific, plastic bricks made out of litter by a woman in Kenya?
I never see you sanctimonious folks coming out and bashing a new product for being made out of brand new plastic. Or criticizing someone for having a plastic device, or driving a car with plastic parts, or wearing polyester clothes, or drinking out of plastic water bottles.
No, I only ever see you people come out of the woodwork is to bash this specific woman, who is taking literal litter and turning it into something useful -- and you're complaining because the litter is made out of the same stuff that your entire household is made out of.
I get that it's popular to bash things so that you can sit back and feel good about how you do nothing to fix the world's problems. But I'm sick of it. Stop pretending you cared about microplastics before you came into this post, and stop pretending you're going to continue caring about microplastics the moment you leave this post.
If you read again slowly you'll realize your comment has nothing to do with what I posted.
I was addressing the comparison between using the plastic bricks vs sending the waste plastic to a landfill. Nothing else.
So recycled plastic is worse than new plastic? Or is this part of the fashionable "criticize every improvement while doing nothing to better the world" mentality?
It's not a question of the plastic composition, it's a question of the location of said plastic.
In a landfill, the microplastics are significantly less likely to leech into the surrounding environment than, say, if these bricks were used in a structure that is closer to a body of water that the runoff can flow into (including sewage systems). If they were bricks made of new plastic, I would have the same concerns.
So... let's criticize this Kenyan woman for using literal litter to make construction products instead of using the plethora of environmentally-sound landfills throughout Kenya.
Meanwhile, let's never even think twice about using plastic in literally every aspect of our lives.
You're my fucking hero.
Unless we wait a bit and someone comes up with a much better way to get rid of it.
Sure, but it's not like the plastic she uses for the bricks won't do that anyway. We all need to use plastic less, but this way, at least the plastic we do use can be reused in a better way, assuming it's a more efficient process than recycling.
The plastics (as the common folk understand them) need to be destroyed. Should they be reused, it should not be for long term things.
Plastics leech out bad stuff, that's why you should not reuse plastic bottles. Having a home made out of plastic is inviting danger. It's not made of lead, but there's a reason we don't use lead anymore: they leech dangerous stuff
If covered in a mortar or something to block from UV light and insulate from entering water/soil would last longer.
If used in construction the bricks would be covered with render or stucco anyway.
Look into the Precious Plastics project. Similar things, similar machines but this one may be stronger brick wise. Look at the sheet press for instance.
The main difference between her project and some of the other recycled plastic into construction materials is that's she's making bricks and not boards or prefab sheet walls, which will probably make it more marketable to a larger customer base then previous projects in Costa Rica and Colombia.
My fear for these bricks is fire. If one of these bricks is on fire the rest of your house is on fire 5 min after.
As a firefighter, I can tell you that the smoke from these “bricks” is going to be both flammable and highly toxic. The neighborhood will have to evacuate as the house turns into a giant cloud of hydrogen cyanide, and the runoff from the fire hoses could easily become part of the aquifer.
This is a phenomenally terrible idea and we should recycle plastics in almost any other way.
I work in the furniture busniss and i did multiple courses on flameability in houses. The difference in flameability in foames,curtains and that kind of stuff. The toxis air and speed with it burns. Its so scary. You cant do anything. In the Netherlands there are different rules and regulations but even then.
Yeah most people die from the fumes long before the fire spreads very far
Hey BTW people, don’t keep that dry old Christmas tree in your house, get rid of that shit
I got some news for you about the average house fire.
House fire speed
But yes, this will likely be impossible to extinguish and really toxic when it burns.
These were my thoughts. Construction materials have to go through rigorous design and testing to ensure that they comply with building regulations and that they will perform in the event of a fire. We had a fire on site about a year ago because someone put a cigarette end in a bin. The smoke has horrendous and I went to hospital as a precaution for smoke inhalation.
but what happens of theres a fire? does the block just melt into a wet hot mass?
No. It burns like crazy, spewing toxic fumes
almost five to seven times stronger than concrete
almost five to seven times stronger than concrete
I highly fucking doubt that. They probably did those dumb "doesn't break when you hit it with a hammer so it's better than concrete" tests.
Concrete is not made to withstand shock but constant pressure! Because that's what buildings do! Apply constant pressure, not hit you every now and then!
it's nice how in your mind they couldn't possibly manage anything other than "doesn't break when you hit it with a hammer so it's better than concrete" tests, then you argue against this scenario you are certain happened
It's the "probably" argument
Do they have a homepage where more research is possible?
This seems practical.
Edit: I legitimately mean this. Why isn’t it being done more?
My guess is it takes a lot of energy to transform the plastic into these bricks 🤷🏻♂️
do you know how much it needs to make concrete?
The CO2 production of concrete is a real problem. And they search for other solutions.
This is surely not THE solution. But it is a reuse of resources and at least it reduces the amount of plastic waste in the nature.
well a guy did a ted talk where he talks of a concrete his team made that actually ABSORBS co2, making it carbon negative. Plus it set within 2 days, saving the use of water to keep the concrete wet till it sets.
How we could make carbon-negative concrete | Tom Schuler - YouTube
he has no obligation of telling you the truth, and you have no way of confirming what he says
also, he is trying to sell something
If the invention works, your point is moot. Also, TED is a respected organization and this speaker, whether he's right or wrong, has been invited by his peers to talk about his invention. It's fair to consider the idea without assuming it's trash because you personally don't know much about it.
According to OP it costs $7.70 per meter squared.
That's insanely cheap for one square meter of plastic. It would definitely be very energy intensive to melt down too.
I wonder if they're burning more waste plastic to be used as fuel to run their machines?
Probably because the other properties of plastic don't compare to real bricks, strength is only one property. Plastic degrades from UV light due to scission, so the lifespan of your structure is significantly shorter. It creeps (slowly changes shape) under stress which is also rate elevated by temperature, so the whole weight of a house on a hot day could compromise the integrity of the building. It likely has worse fire suppression due to low melting point.
The other questions to ask would be, how do you adhere them together, cement based materials work very well for brick, what do you use for plastic?
All excellent points; and, even beyond creep the resistance to is likely both variable and very dissimilar (i.e. worse) compared to brick or concrete.
Concrete blokes are probably cheaper to make and mass preduce
And there are a lot of rules for what can and can't be used in a building
Source: I'm an architecture student
I thought this was posted a while ago (could be mistaken) but someone said that the material is a huge fire hazard. Basically it’s just straight up fuel mixed with sand.
Yes. Imagine being a firefighter and trying to extinguish a huge tank of oil or gas. Because thats what this is.
Don't get me wrong, I think that these plastic bricks will have some use cases, but please let architects and engineers consider fire safety.
And it's also gonna be extremely toxic when burning.
That's exactly what came to my mind first. I love the idea and all but fire and plastic is a very very bad thing. You don't want to be in a burning room with plastic melting in. That said, there should be additives to make it fire resistant for a certain while. But that's probably increase the cost to not make this feasible.
And a huge health hazard if it does catch fire, sweet toxic plastic fumes.
These blocks probably emit a noxious gas and are impossible to dispose of.
That all depends on the location of the aggregate sources and cost of shipping... if she is next to the plastic source and the concrete sand is way far away, she will beat the unit cost.
Well, I imagine a bloke made of concrete is cheaper than a living breathing one...I'd hope
We’re running out of the sand which can be used to make concrete though
It is a very shortsighted practical solution that will cause major issues in the future, while i agree plastic should be recycled and properly disposed of, this has many issues, from micro plastics leaking into the environment from erosion of these products over time, to offgassing and poisons leaching into the homes and ground surrounding over the years. plastic is not a long term stable material. additionally there is major risk in fire, a concrete house burns down and stops or can be put out by firefighting, if a house made of plastic burns down it will burn so hot and quickly there is no chance of stopping it while all that plastics pours poison smoke into the air and water, imagine a large suburb burning down with all the houses made of plastic, like a wildfire situation, it would kill people just from the smoke alone. i applaud the effort, but the forethought and consequences for future generations was not well thought out.
Right, but if I was given the choice between a plastic house and no house I’d still pick the plastic house.
Before getting too excited, I'd like to how many micro particles of plastic these give off as they age. They could well be worse for people and the environment than their original form and that's something which needs to be looked into.
Also what if a fire breaks out? Concrete is stone so its pretty resistant, imagine a fire in a plastic brick building, might cave the whole building as each brick loses its shape
I was wondering what the issues with this could be. Now I understand why it's likely that nobody cares about this.
How could it be worse? The plastic is already out there and will turn into microplastic either way
Yeah but instead of being condensed into one area (preferably away from major water sources) you’re spreading it everywhere.
It ends up costing more than concrete because you have to make a special blend of plastic, pure bricks of plastic would warp in the in the heat and make the house unstable after a few year houseotwoulwarp in the heat
Me: Has done a lot of firefighting.
"How flammable are those bricks?"
Seriously, fire safety is a big deal. We have to stop building homes out of oil and oil products.
Well, major concern: they aren't stronger than concrete. Last time something about these bricks was posted it mentioned that the bricks don't break when you hit them or something, and that apparently means they're stronger than concrete. But concrete is supposed to absorb constant pressure not shock.
Other concern: fire. Those things are gonna burn pretty well and be extremely fucking toxic at that.
Some variant on this "somebody INVENTED a way to make BRICKS out of PLASTIC" shit gets reposted every six months.
Plastic bricks have been a thing we have known about for literally a hundred years now. They are not a new invention.
You haven't heard of them because we don't use them, and we don't use them because they suck.
Plastic burns. When it burns, it drips burning plastic that sticks to skin and kills you, and releases clouds of toxic gas.
Plastic bricks are neither a new invention nor a useful one.
Please stop reposting this shit.
It also doesn't take in water well, and depending on how used it is, it spreads microplastics everywhere which is just as bad as normal plastic.
Well, I'm not an expert, but I read that they are mixed with sand which makes the melting point quite high. Not really sure how useful they are though
Even if the melting point is high, it's still lower than concrete. Concrete is probably as fireproof as a material can get.
Yet people still build houses out of wood... It's almost like melting point isn't the only decision.
People have mentioned how wood isn't toxic, nor does it melt.
It also doesn't become brittle with cold or age. Wood also costs less per yard than a yard of plastic bricks.
You're right it isn't. Wood is so much superior to this plastic garbage.
For starters it doesn't melt and doesn't produce toxic fumes when burning.
wood doesn't melt tho, its almost like you don't know what the fuck you're talking about
We'll be making giant lego houses in no time!
I'd be so fucking down to build my own house with large Legos
You could have tons of leeway AND you could rearrange it!
The entrepreneurial aspect is great, but I'm not sure stronger plastic is in the world's best interest.
I think the bigger issue is flammability
They are a mix of sand and plastic and considering how compressed they are I doubt they would actually burn, they melt at around 350 Centigrade so are safe for paving slabs.
Paving slabs is how they’re being used. Can’t be used in building construction.
Sounds great to me as long as they don't break down quickly in the sun. Concrete gives off a lot of co2.
since its waste they cannot process anymore i assume its not flammable, experts correct me pls
If course it's flammable. The waste was flammable, too, why would this be different? Probably less flammable due to the sand substrate, but it's still a hydrocarbon polymer.
What's a better suggestion, i am curious? Since she uses recycled plastic that ought to be already a plus (depends too on the emissions to produce this) and if these are much stronger maybe they remain intact when a building of it needs to be demolished so they could again be reused (by then someone might already look into it).. in any case we are constantly building more infrastructure so using these instead of concrete will help more than damage. But im open to corrections.
I agree but think the original point ignored the recycled element of this and focused on the general idea that we don’t really want to encourage more plastic use.
Its the single plastic use that we are against mostly. Not totally plastic
Define stronger. What does it mean in this context, harder, heat resistant, shatter proof, denser, etc?
People complaining because this isn’t “The Solution” to plastic waste, as though she’s claiming it is. Obviously the world needs to eliminate single use plastics, but we also need to accept the inconvenient reality that the world never has and never will change overnight. Taking single use plastics out of landfill and oceans, and repurposing them is something good that can be done alongside and in the meantime, while taking steps to eliminate single use plastic production. This is a great thing to do while winding down plastic productions which, lets face it, is not stopping anytime in the near future
We really need to shift the mindset of seeing these things as a zero sum game. There is no ONE SOLUTION, just a series of many, many different steps all heading in the same direction
It's a step in the right direction, but this doesn't fix anything. People will wear the plastic down on these bricks (because they walk on them obviously) thus spreading microplastics every where, which is just as bad for the environment.
I want to add to this comment that I don't think her solution is just towards plastic waste, it's also for cement. The making of cement is also one of the largest detrimental factors to the planet's climate.
And yes, I fully agree with your last statement.
Interesting. Wish I could find all the details on it. I'm only finding the "feel good" story info.
What about Fire safety? Long term deformation due to the material plasticity? How is "strong" actually quantified as here since we are talking about Materials Science.
Anyone have a good link?
Are they flammable though 🧐
Not trying shit on her or anything.
Just confused because isn't many govt's already using plastics and mix it with concrete & stuff to create roads that are actually stronger than normal roads....
Coz i have recently read about plastics used as landfill of some sort to make roads in india. And they said 2x or 3x more durable than Normal roads.
Not sure if both are same thing. So i am just curious.
They are being used for paving bricks apparently and not for house construction. Considering possible flammability I think its really smart. Good for her, she found some use for plastic waste and a new paving material along the way. It sounds a lot like turning old tires into playground turf.
I guess my concern is run off. Would those bricks eventually break down and leave plastic in our dirt?
Recycling plastic: good idea
Plastic bricks: probably bad idea
This is brilliant and I commend her for her genius. I wonder if they’ve tested any of the bricks for the possibility of them gassing off and being harmful in the future? If they don’t have this effect this is double brilliant and she should be nominated for something
Thank you OP for mentioning she's an engineer and mentioning her name in the comments.
I've seen so many sites with the headline "Kenyan woman finds/discovers plastic bricks", as though she didn't develop them scientifically, but just stumbled upon them one day when she was getting water for her family.
I wonder what the footprint on the process is like
But dies it melt in extreme weather conditions?
That would be a concern for me
350 degrees Centigrade? I don't think I would call that weather.
Honestly that great and I know the Blicks are made of sand and plastic but I really wonder how good the fire resistance is. You know would be quite unfortunate when the floor is lava, and the Walls too.
It’s a nice gesture, but it won’t catch on. Plastic gives off toxic fumes when it melts and there are simply more bricks in the world already. Unless these bricks can be found worldwide, they’ll never be as easy to buy as regular bricks. The vast population as a whole will never move onto something more expensive/dangerous and less accessible/useful for the sake of environmentalism. The core issue isn’t providing an alternative to fossil fuels, plastic bags, plastic bottles, non electric cars etc, it’s making them obsolete entirely.
Modern Buildings arent made to last, theyre made to be easily torn down.
Im not really sure bricks 5 times stronger than concrete are beneficial in a large scale architectural sense.
Go watch this : https://youtu.be/QbZKP4UAtL8 it's really interesting !
Another hero we need but don't deserve. Brilliant work, Ms Matee!
Trevor noah will be happy with the ultimate face brick
Is it a super low quality chocolate now?
A better weapon AND it’s helping the planet
Shes the hero we needed but dont deserve
... That’s good.
Kenyan engineer recycles plastic waste into bricks 5 times stronger than concrete.
... sorry couldn’t resist :P
Finally some real news. Let's keep it going!
Now how many bricks can you make out of the Kardashian’s
Im so proud,😭😭😍😍
Finally something that won’t break in my ass.
I don't know much about the technology but something makes me skeptical about fire safety characteristics of this material. Therefore, a lot of plastics are toxic when heated and it's easy to heat them by putting them outside on a sunny day and I think there's plenty of hot sunny days in Kenya.
I LOVE THIS!
So you might escape your house being on fire, but you won't escape that dioxine cancer!
And a thousand times more flammable?
And they burn 100 times faster
Let’s all do this. Get all the plastic waste and do this,we can build a lot of stuff and clean up the land. What this woman has done is amazing,
Free cancer for everybody when these buildings catch fire. And also probably for the factory workers that make these
This seems practical but one giant thing preventing this from standard practice is insulation, how much heat they can withstand, and if they can be chipped easily.
We need to invest in this. Corporates and governments, do it!
Go her 💪🏼
Is it 5x the tensile strength of concrete?
I’d hate to be laminated in a house fire
Those bad boys will burn for weeks!
I see one of these sort of innovations every once in a while.....but later I never hear about it
And they’re also very pretty
Are they flammable
How long till Demolition Ranch buys one to test with random guns?
Musk, invest in this.
... and that's the last we will hear of that world changing invention
“fiVe tImES StRonGeR tHAn CoNcREtE” bish doubt it that’s so vague and also concrete is probably wayyyy more affordable and a much longer lasting material
Everytime I see an article like this, I turn into Peter Griffin about Funding these projects for worldwide.
Would love for this to be a thing! But I know damn well it won’t because it won’t make the corporate clowns any extra money.. I’m hopeful that this genius will have this become a Mainstream idea though.
It's already a similar thing elsewhere. Look up Hahn Plastics. Not bricks, but slabs, ground and bank stabilisation, fencing products etc, all from 100% recycled plastic.
All good and well until your house melts
Thinking of the recycling situation in Kenya (if I think correctly about it), this idea is great!
I'm just wondering how to stick the bricks together? I can't imagine concrete adheres to the smooth plastic surface.
Thought this was a 5th grade boy for a minute and was super impressed
And somehow we won't ever hear about this again...
Can this be done with the great island of rubbish in the ocean? If so shut up and take my money to build a factory asap
This is awesome to see !
German "Housebuilding-Bricks" as far as i have heard of from various sources are made in a way much quicker then they used to be decades ago. Therefore are way worse in stability cause they arent dried as good as they should be cause that takes extra time.
So seeing this, that someone makes a competing thing that can also be used perfectly fine as a building block is very nice !
Maybe someone can shine a light on how the bricksituation is, in its own country ?
Trevor Noah needs to hear about this. Frickin beast on the playground
5 times stronger
5 times stronger
Ah yes, you gotta love these vague claims. Don't be specific, just say its x times better, that's all we need to know.
When I watched an Apple keynote I was surprised at the amount of times they stated the new product was x times faster than the competitor. There was no indication at all of how this was measured or what the testing conditions were, or even which competitor products they tested it against. All they did was show in big bright letters "6 times faster". Yeah, that doesn't say anything mate.
My old toaster toasts 5 times faster than other toasters.
Ok Reddit, why isn’t this sustainable? Someone always finds something wrong with awesome innovations.
Good for them, I hope they see this to know that we're proud of them
