Plastic Bricks

Hello everyone,

I was reading the topics and comments on the Forum and there are a lot of discussions about plastic bricks, lego houses and so on. Because I am supposed to begin some tests making bricks with PET powder, I decided to write a new topic for this subject. The bricks are not 100% plastic because it should be very resistant to be a house’s structure.

I would like to know if someone has already started this tests or projects building houses with these bricks. Let’s share ideas, “brick recipes” and molds inspirations.

If the molds work like lego toys, it would be much cheaper and sustainable. I really like this kind of bricks (https://www.facebook.com/JungleVT/videos/687153871457299/). They are wood bricks, but work pretty well.

Let’s recycle and make the difference!
Cheers 🙂

Luiza, there is a lot of people working on it. And I do not recommend it. If you need further information, send me an email to : marcelozp@gmail.com

Hi Thomas @teslaguysquires,

 

Interesting concept, but could you please add a drawing or two?

I think I got most of what you are describing, but a few pictures would make it way easier to understand.

 

Or if somebody has any photos of a similar contraption, even better!

 

Hello folks , I am going to add a ton of comfort here for all of you wanting to produce artificial rocks / plastic bricks / and any other product here in our community . Firstly , only an original initial product is required = 1 or more depending on your scale of manufacturing required . A high heat automotive silicone can then be used to make all additional required mold  items , as long as the outer shell is solid . A very finely finished surface can also be achieved by simply filling and sanding with an automotive finishing putty . Next or an alternative is to make all additional molds out of fiberglass … so 1 template can be seriously multiplied …
when you see what everybody else is doing , add to the concept as in a better mouse trap , lol, and this is going to be great for everybody here because , the simple addition of a waste cooking oil or motor oil drip over the melt input will create a mold release agent and a better flow product , but a slightly over normal temperature will be required for production runs …
when we consider the UV (ultra-violet )factor into manufacturing potentials ,we must all consider what waste polluting plastic degrades the least when exposed to the sun , if quantities of that are not available , then proceed to the next level of degrading plastic . We must all remember that there is always a solution to a problem , when we share information and seriously discuss potentials , as in a plastic paint with a UV agent mixed into it = problem solved .  eg . as follows ,
way back in 1984 , I owned a house that required painting , so I used a polyester paint base , and combined that with an automotive polyester resin curing agent , and the result is that the house is still the same new looking color and same trim colors , but still look like new when pressure washed …the next paint development is a rubberized paint that can be tinted to any color , and then over sprayed with a clear UV gloss or matte finishing  application , only extremely high heat applied will allow for the paint to be removed without any original prepping of the under surface … the next is a residential application in development as we communicate , with nothing like it anywhere in the world …
As we research into our requirements we become much more intelligent regarding the subject of study , because that is where our focus is projected , so when we consider the structural strength regarding plastic bricks or plastic rock facia  forms , we see that a few people have already answered our question here , because many are adding a sand or dirt substrate into the mix , which can be done by a funnel application over our input mix tube , with a slide flow control mechanism at the out put port … continual flow potentials of waste plastic into the hopper  can be a simple belt or screw input addition with variable speed control for melt capabilities …
I see that a few people within the community are from very limited industrialized areas so , consider a 16 or so foot slide plat form that flows through 3 horizontal steel barrels welded together , your base is a solid brick wood burning stove with the horizontal barrel structure above , scaled as required for wood burning in the oven , with clean out ports , and wood input ports … your input air can be several re cycled computer fans running on several small solar cells , your exhaust can be a welded or brick over form that flows into 2 or 3 vertically welded together barrels with the input at the top area and the out put about 1/3 of the way from the bottom of the vertical barrels , water tubing or containers can be attached for hot water capabilities as well , a clean out grate area at the bottom of the vertical barrels can be also created for the heavier than air particulates , a draw air tube can  be side attached back into the fire as well for extra burning of any carbon resulting from any smoke or un-burnt potentials , your vertical barrel out put exhaust air can be long cycled so as to capture heat as well for pre heating of plastics or waste oils , … re-cycled plastics with wood burning and clean exhaust emittence …your mold form can be a slide in application run by a solar powered or manually pulled through melting system with a heavy out put door so as to slide over the molds and auto level all forms for ant potential over fill melt …
I do hope that I have given a few new potentials to this group for considerations …good melting and wishes to all …Teslaguysquires out for now …

for around 10000 – 20000 + Euro any well equipped machine shop could do a near full-automatic brick machine: hopper → shredder → large extruder → heated pipe acting as deposit → hydraulic press → cut off. takes 1-2 months to build. such system would be 2 – 3 meter long and about 300 Kg.

Can someone calculate the approximate cost for the plastic brick machinery ?

Please people!! Continue to expand this subject, I think construction is one of the most interesting, polemic and potencial stuff we can do with plastic waste… thank you very much to all of you

@pei.  There are several videos on YouTube, of people in India doing this. They are using empty water bottles as filler material in cob style houses and other structures.  They are quite beautiful.

@luizafazzio @fairywhiz

hi luiza and everyone… what about plastic bricks covered with mud and straw 🙂

@luizafazzio how is the progress going?

Thank you @jims

@luizafazzio I dont know much about this subject just thought about a company in Mexico who is building houses with plastic in a week for a couple hunderd dollars. This Startup Turns Plastic Waste into Affordable Housing - UNREASONABLE Maybe this can be usefull for you. And yeah why not finish with an inspiring quote http://www.bradnash.com/blog/isad-here’s-to-the-crazy-ones-apple-steve-jobs-quote/

it can be done relative easy with little to no danger. you need a good and large heating source, a second hand pizza oven(1.5 sqm, 200-1000 Euro), and some larger hydraulic systems driving a mold system. if you have a machinist around, it can take up to 3 weeks to build such system but let’s say you acquired the materials second hand, it’s about 3000-15000 Euro for all, only. no extras for safety measures or automation included yet.

Hi @luizafazzio, I am also thinking of this plastic brick concept but it seems it may require a little more research especially relating to flammability and safety… Although there are few youtube videos on various concepts for making plastic bricks, they don’t exactly talk about health and environmental long-term consequence and safety testings. Please share if you also obtain any helpful information. Cheers

Hey @mdcn25! I’m just typing in english so others can understand! I don’t have any molds yet. I’m still planning the process. Fist I need to study more about the safety of it. Have you ever tried to make bricks? What projects are you planning to do on the NGO (if it’s possible to share)? Thanks 😉

Hey, I just joined this, but my company is working on making materials to build homes out of plastic. We would love to work together to make it happen. please feel free to email us at earthrebuild@gmail.com! hoe to hear from you

Olá Luiza, como vai você? Bem, estou lhe dizendo que sou do Chile da cidade de Arica, membro de uma ONG chamada Tortu Arica, gostaria de perguntar se você tem algum molde de tijolo e qualquer outro molde, estamos em um projeto de reciclagem de biberões, obrigado de antemão,.

All these people saying plastic are no good for building don’t breathe, off gas and so on, I guess building houses from polystyrene and polyurethane foam would also be a non starter then? Seems people are building walls for themselves to stop themselves and others? There are a few companies mixing waste plastics with sand to make roof tiles also. I say stick with it, render-stucco will stop UV, tests will prove which way to go for structural integrity. Timber frame houses move with the seasons and humidity, some boats that survive the worst that can be thrown at them are held together by bits of string.

@Luizafazzio
Here are a couple of YouTube video links that may help. 🇨🇴 Colombia's Lego Homes - earthrise (lead) - YouTube.  “Columbia Lego Home””This company in Columbia makes houses for people that are plastic.  The second video makes roof tiling out of recycled plastic.  “Eco Friendly Plastic and
Sand Tiled Houses” ECO FRIENDLY Plastic & Sand Tiled Houses - YouTube.
*     If the links don’t open, type exactly what I have  written in quotation marks.  I hope this helps.

I’m also interested in using processed garbage for building. The Eco-Maquinas website has a reference to the Zonlix process for sanitizing and processing any-and-all garbage into lego building blocks.

https://ecomaquinas.com.br/index.php/eng/tijolos-ecologicos-com-residuos-do-lixo

Although, it seems that if the garbage could be pulverized sufficiently, it could be washed in a chlorine bath to sanitize it and a soap bath to degrease/wash it. Once dried again, it could be used as a supplementary aggregate in brick or possibly concrete.

Of course, studies would need to be conducted for human health concerns, strength, and longevity.
