If tongue and groove slots were added to the sides it would probably solve a good bit of the lateral strength issues.

It’s admirable that you guys made sure to point out the limitations. I remember seeing a similar product called Lok N Blok which has seen some adoption in South America, but it isn’t fully recycled and only uses higher grade plastics.

One use I can see for the plastic bricks is interior walling. It'd take some work but imagine a ware house, then you bring in a ton of these lego block walls, you could design what ever sized rooms you wanted.

If the design for the big bricks were more in line with your Giant Legoish brick I think the Viability becomes more viable then they realize. The ones you guys made can be covered in plaster, mortar, or concrete and filled with foam for sound deadening. I could see them used for quick and easy building foundations which can turn a 90 day modular building project down to a 2-3 week building project time.

It is important to remember that reducing the amount of plastic we have is one step of the battle. Stopping plastic being made for 1 time (or less) use items like superfluous packaging is a very very important and necessary step! PS: I love their bike shed!

It may be beneficial to make a more complex mold that extrudes bricks with "I-beam" like fullering properties. Use less material and decrease weight while not losing much in the way of strength.

In 2021 CBS told the story of Material Scientist Nzambi Matee, she is making bricks in Nairobi, Kenya out of plastic waste cluttering the streets of Nairobi. It is truly awesome the work you are doing, encouraging people to do more with plastic. Thank you

I like you guys. I love that you’re involved in the conversation and you’re excited and spreading the word but not lying about anything. I think it’s great

Love this idea. I'd actually quite like a shed made from these...

The outdoor furniture that circular11 make looks astounding, they are phenomenenal and the molds keeping the wood grain makes it really just look like spray painted, pressure-treated wood which is so cool. Such a great use of low grade plastic. Definitely isn't low grade anymore, that's awesome.

I was wondering about the bricks. It seemed like C11 was reinventing injection molding but without the benefit of the last century's worth of automation innovations. Extruding construction planks is a much better workflow for their machine.

My sister recently started a nursery daycare. The small blocks would be perfect for the kids to play with. She's always coming up with creative ways to entertain the kids. And these would be perfect for her and the kids.

I love the idea of the bricks, and I would love to see dome houses being built with them. Yes, I know not many people like dome homes (I don't know why, I find them very esthetically pleasing) but that and/or Santa Fe/adobe style homes. The bricks could be covered with quickcrete or similar compound that would also be nonflammable? I'm not a builder or architect or anything like that, so I'm just making stuff up. I have no idea how feasible any of this would be. Just dreaming. Thank you for the awesome videos!

I've been fantasizing making my own recycled plastic bricks for some time. Thank you for all your research 💚

After seeing your round plastic "bricks". I would think you could produce a plastic cabinet set with tilt out drawers for small hardware, sewing notions, etc. The commercially made ones are awfully expensive. Yes, having the commercial ones with the clear drawers is helpful, but I hot glue one of whatever Item I have in the drawer on the front to save time, even on my clear drawer units. The drawer units could interlock similar to the bricks so a person could add sections, or easily dismantle it if it needed to be moved. I think this could be viable for a small scale local production, sort of a "co-op" type setup. One group makes the cabinets, and one group makes the drawers. Just some thoughts.

These are a fantastic idea, but will face the challenge of overcoming what I call 'the inertia of tradition'. Cinder blocks are ubiquitous now, but faced many of the same problems that these bricks face today. Prior to their widespread use, kiln-fired red clay bricks were the go-to building material for most buildings. Then, cinder blocks appeared, and were immediately compared to the standards established by the red bricks for strength, durability, etc. But, as their use increased on smaller projects, it became apparent that they were cheaper and faster to make, easier and faster to build with, and yet still capable of holding up over the long haul for most jobs. I think it will just take time and finding a niche market (like emergency housing) for these bricks to become mainstream. One thing I thought of was essentially, tiny houses, in a kit. Preferably palletizable. If they could come up with roof tresses also made of this material, you could have an emergency shelter that could be brought to a natural disaster area, dropped off and built within a few hours. Even an 8'x8' shack is better than sleeping outdoors. There is another channel I've watched where they make 1"x3"x6' planks out of recycled bottle caps, then use those planks to make park benches. No one worries about sag, or flammability, or UV breaking down the plastic, because park benches are innocuous items. Here, if you are going up against the building industry directly, you will have a fight. But, if you can find a niche market, like emergency shelters, or sheds, or even raised garden beds, you have a chance to get your foot in the door. Once people start using them in these roles, they will start to wonder why they aren't being used in other roles, like housing for homeless, etc. Now, I've done some experimenting recycling #2 (HDPE) plastic coffee cans (US here), more as an attempt to see if it could be done at a home kitchen level, more than anything else. Reviews are mixed. I was able to take a couple dozen coffee containers and reduce it down to a blob about the size of a building brick, but that's as far as I went. Basically, reducing the volume of the plastic waste from a garbage bag to a brick. If I didn't live in an apartment building, I would have pushed the experiment a bit further. But, overall, I learned a few things for myself. Sometimes that is where the fun is. Also, on a side note, one possible solution to the flammability and UV damage problem might be in a coating like adobe. It can help with the thermal properties as well as sealing up any gaps between the bricks. since adobe is applied to a mesh that is attached to the wall, regardless of the wall's building material, it would help with stability as well.

What if in the disaster relief application you made building tools rather than bricks? Clay brick molds, tempers, connecting hardware for pole structures...

Hi, a few questions if I may. Any outgassing or leaching of harmful chemicals into the environment? Does the plastic lend itself to additives to help with fire resistance? Same question but about incorporating for example metal into the top joining lugs to aid in strength and rigidity? Or even adding strength through an alternative manufacturing process such as lamination like plywood or osb.

I loved the circular styled bricks that you've made. Personally I haven't got a use for them, but they looked great.

hi how are you My name is Habtamu from Ethiopia. I really like what you guys are up to. I tried this many times before I saw your video, but one day I found you while searching on KZfaq. I am very happy. its very good job

Great video. Interesting topic on scalability. Mahalo for sharing!

This is absolutely amazing. People like this are going to make the world a better place. Way to go!

Hello, your homeland is wonderful. I wish you good health and success❤❤❤❤❤❤

I can imagine low cost hotels made of those big bricks and you can just adjust the size of the rooms, the lobby or any of the other premises at any given time, whenever extra rooms are needed during high season.

I see those bricks going little farther than garden walls with decorative sunlight holes, areas between existing posts such as steel carports, interior basement walls, animal pens (waterproof locking required), and perhaps sheds. The furniture tickles my happy spot.

Law of headlines says NO.

Would suit internal walls. Saw on KZfaq an Indian /African making normal sized bricks out of plastic waste.

I love this project so much.

Your bricks also look like they’d be useful for stackable bins!

You don’t talk about the massive amount of energy it takes to melt the plastic to form the bricks.

great job guys have a good weekend to the team and the brothers

The thermal shrinkage makes the bricks come out sooooo smoothly

I like what you guys are doing. I am saving up to be able to replicate sone of the things you guys do.

Seeing both the bricks and the round things, I wonder how plausible it could be to design a fusion of the two, where if you need different shapes, moveability, the round pieces can act as a pivot point connected to the brick ones? The underside could be made in a segmented way to allow the round part to fit snugly and not move/shift around. Plus, perhaps adding things like rebar and some other material to add structure into the gaps, and a coating on top of them and the sides after also. Could allow for interesting shapes, depending on how the brick pattern is designed I'd imagine. You could even use Minecraft or similar as a way to work on prototype building ideas as a super bare bones idea for these blocks I'd imagine. If there is a mod/setting to add physics to it, you could then see what would need more supports in builds also. Best of luck in your journey for this product.

Love the video - I'll be doing more research such as, types of plastic that can be used HDPE? ABS?, how to paint, insulating properties, and so on.

have they considered using concrete filler/cover to help the sag/uv? maybe an overhang and bolt arrangement to bolster the tabs these look like they'd be great for marine applications. can actually get the value you'd need for them there.

=) Can't wait to see these guys do well with their recycling.

Our charity is using a specific brick shaped bottle called "WaterBricks" to hand pack single use waste plastics into - to build fun rearrangeable brick art, play furniture, etc.... We are looking into covering the brick sculptures with yarn graffiti, and large-scale dye sublimation marketing coverings - as event displays and barricades.... No grinding. No melting. No fumes. Just bread bags and candy wrappers getting packed into something aesthetic and useful. The WaterBrick bottles may be a great place for unwanted mixed 3d print bits too; especially if you don't have a granulator at home!

Awesome. Would love to build something with these.

I love the bricks. I got some off Ben back in early 2021. It is amazing to see how much they have grown and the positive impact they are having.

I've been in construction in the Northeast USA for 15 years and I've never encountered the word "render" before. I looked it up and it refers to a coating on masonry like stucco, which is pretty much what I got from the context of the video. Maybe "render" is used in areas of the USA where stucco is more common, but it seems to be common in the UK.

Heavy duty plastic moulded shipping pallets for Air dropping of Humanitarian supplies that could be slotted all together and bolted. To make a curved style roof covering for small aid shelter when put on top of a simple dry stone wall.

@LincolnBlockInc have similar blocks from waste wood offcuts. They join them with a bead of Silkaflex sealant/adhesive and fill the voids inside the walls by shooting expanding foam down from above before capping them off.

Great video

Add some recycled pallet wood for the form, now you got roads out in the boonies for years to come, easy material to get to maintain the roads.

Disaster response notion excited me.

There's actually companies around the world that are doing similar things, making building materials out of recycled materials. They tend to be a mix of plastic or rubber with clay or sand or other material. That allows them to be less flammable, but I don't know about uv resistance.

Framing boards and sheets would make more sense, using a continuous extrusion process.

These bricks are such a cool idea! Looking forward to a future when these become more commercially viable. Circular 11 look like they are making some great moves!! :D

Love the idea, just wondering how these materials would hold against a disasters such as earthquakes, flash floods, etc.

Hi, I really enjoyed your videos and I'm learning a lot from it. I'm a design student and also a diver, so I want to create something using ocean waste. I was wondering if you know of any techniques/ways to recycle ropes, nets & fish cages(?) :)

Curious, in Florida the homes are built with cement cylinders/bricks,then the walls are covered with stucco. Could the stucco over plastic bricks prevent the breakdown and deal with the flammability issues?

I love this idea. Couple questions: 1. Looks like a labor intensive process. Is it economically viable? 2. Does concrete adhere to it? 3. Could you mix in ground car tire rubber? 4. Wouldn't it be better to extrude a long profile and cutting it in bricks instead of making individual bricks one by one?

Very nice 🎉

Hola muy bueno ! Se podria contar con las especificaciones para hacer el molde?

i was just about to say that this would be a great idea for lego-like bricks and then you made them! and it could be a really cool thing to gift them to kids in a local community, or even have the kids help out in collecting the plastic? and have it become a teaching moment where they learn about how plastic is recycled?? i'm just spitballing here haha

I used some plastic planks for deck boards on my bering sea crabber.. The boards got smashed hard every day. 900#lb crab pots drug across them with hardly a scratch. Durability and longevity. Great material.

The round ones look like cup holders in cars. I think eventually someone will find a good use for those. I'm glad people are thinking about it 😊

I think and hope their business model takes off and is very successful to become more mainstream to replace the brick construction commodity

These would be great in an enrichment playground.

A New Zealand company Makes recycled plastic farm fence posts, They ad a compound to the plastic for added UV protection.

Love it ❤❤❤❤❤❤

素晴らしい取組み👍🏻

Love the channel, interesting video. Turning what you are doing, and others who have the same enthusiasm, trying to make it profitable is certainly challenging. As someone who used to work in injection moulding and tool making it takes a huge amount of money and resources to run a business. I was wondering what resources are available to you to purchase an injection moulding machine Arburg are small and reliable. Also the recycling process was one we had. Love what you are doing. Making a difference. Best wishes to you and the team.

What temperature are you heating the plastic too, and how are you dealing with the plastic shrinking when it cools?

I've been wanting to do this for years but have no idea how to start! I actually helped out at some plastic recycling in Indonesia which was a good experinece! But any tips/advice/ would be really helpful!

How are you detected tipe of plastic? What the detector are you use? Thx

what a fascinating product! these days i am going to conduct an experiment to produce sand reinforced plastic panel sample and how can i build a "small furnace with an extrusion tip" simpy at home?

If it doesn't take hold in the construction market. Might I suggest the kids toy market? I would have loved these as a 8 year old boy.

I really like the concept and honestly, using this method would actually help with housing crisis and even plastic waste. These fellas are basically making Lego but big boy sized

You should see if you can get a tour of Johnson controls clam shell facility in Washington state I used to work there when I was young, I think you could really learn something about plastic extrusion, your loosing a lot of structure by not beeding your remelt before you send it to your auger for extrusion, it's basically mashing it self between the blades of the auger

Interconnecting planks would be a big hit. Inch thick maximum, use case could be fencing as well as housing with outer planks like the case of wood cabins, providing protection to elements minimising need for insulation, and relying on wood or metal for structural support and also pest and corrosion resistant. The weakness to UV could be affordably combated by using UV reflective paint, UV reflective vinyl or in emergency scenarios, using recycled milk cartons with the reflective side exposed to the elements.

I think this would be adopted faster as a fencing system. In my area the local law requires an engineer to certify a plan for a brick wall, but plastic would be a long-lasting alternative.

Cool concept, Life size Legos!

Seems like the sort of bricks that _can_ be high value... I'd be thinking far more around reusable brick _system_ for creating forms for casting concrete, rammed earth, etc. The toughness there could be a sell for a variety of markets.

Both affordable housing and emergency housing are strong interests of mine. I'm glad you've shown both the positive and negative for this project, shows we've got a way to go but the effort is still worth it. Keep up the good work!!!

Hello! Can you show how to make a mould to make those bricks???

Imagine they have multiple sets of plumbing built right into the blocks, that get lined after assembly? For plumbing and electrical and whatnot already all just tunneled perfectly room to room.

I would love to see y'all with with Weta Workshop. Those kiwis know where it's at.

Put a hole in the sides too so a rebar can slide through and it can be filled with concrete if needed. Use the wall as an interior wall, clad the outside as you would with concrete block, frame the inside for drywall or just screw drywall right to the plastic wall, as they do in an Interlocking Styrofoam concrete wall system.

Would it be possible to make home canning jars by putting a thick recycled plastic lining into a once used steel can? I know the food safe plastics like HDPE or PET won't hold their shape at the temperatures of home canning, and if the shape distorts you can't get it to seal, but the steel can would hold it to shape at canning temperatures while the plastic liner would make it more rigid at room temperature. It would also provide a wider contact area for the gasket on the canning lid.

You should start to sell similar kinds of molds that would allow people to assemble a workbench or desk out of these molds (using these big bricks)

It seems like the bricks could work well for kids building cubbies at day care centres or cubicle dividers for offices. A lot of uses beyond conventional connection.

Do u have video shown how to recycle type 1 plastic? At what temperature I can melt it down and still has its original transparent color? How is it done? I am making shoe sole.

Seems like it would be a good material to make caskets and burial earns.

some small companies have already been doing that for years here in the Philippines but it hasn't really gained much attention...

I think the gold standard for success with the brick idea would be a portable machine to make the bricks in situ. Trying to ramp up a factory process to supply global demand for building material that meets diverse global codes is a big task. Being able to provide that pop-up shelter idea with a portable machine that eats the trash already fouling the local environment might be a lot more effective.

Really great effort done for idea of recycling plastic but to be more reliable blocks It must be resist fire by adding sand or recycled old buildings demolishing materials this will enhance and add another value by recycle buildings produced waste or agriculture waste Am civil engineer therefore interesting about recycling construction

What about micro plastics creeping into nature and eventually into the food we eat? These plastic bricks will actually speed up that process.

I love the concept of taking old recycled plastic and making useful things from them. I was thinking with the increased need of trees for ecofriendly packging that it would be great to use such plastic as telephone poles. Would their flammability prevent them from being used for that? Could they could be used for road side gaurd rails? Is there any concern that your products leech chemicals into the environment when used? It is far better for the plastic to be recreated into something else than to have it slowly decomposing in the environment unused.

Is there a way during the manufacturing process they can incorporate a substance that is incombustable or nonflammable ? Or during installation the outer layer we use such materials to reduce the risks of fire spreading faster.

Brother where do we get the machine for building this bricks

Ikea houses? I am 100% on board with that.

I'd donate to the research of it for it. I honestly thought of places like in swamps bayous or like new Orleans, and then the one guy mentioned disaster relief or pop-up shelters I don't know what the effects of plastics being under fresh or saltwater for an extended period would be, but it could be really good for foundations that are typically underwater for extended periods of time, the sun amd fire drawback wouldn't bother the bricks as much.. however after all that I'm pretty sure they have 3D printed houses from plastic right? And if you could transport the plastic to the printer and print on site then that would seem so much more feasible..

Those would make great fences or retaining walls

Just curious, how does that "scale" you placed the lego on work? How would it detect that the plastic was made of ABS?

In the end you made dimentional "lumber." That in itself seems a significant reuse. Show us how you made them, please.!

I live in Tucson AZ and our city recycles plastic into bricks through a company in CA called ByFusion.

I wonder if a more efficent way of production would be to machine blocks out of large slabs of recycled plastic? For example extrude, or mould the plastic into a huge slab and then cut/machine a bunch of blocks. Afterwards any shavings or off cuts could just be recycled back into the process? Might cut down on all the time waiting for the plastic to cool and all the individual time sinks of each mold being done.

The seal looks kind of loose. I was thinking sealant but, then your still adding to the plastic problem. Would melting the joints work?
