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 🙂

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.

Hello all

I live in a country where plastic bricks are a reality.  A company was recently hired by Unicef to build classrooms entirely made of unsorted recycled plastic. The only plastic they do not use is PVC. And, yes, completely unsorted. All types mixed together. The final product is a lego-like item that comes from a mold.

They have built one classroom and will build more but I would like to learn how to do this locally. All the recycled plastic they use comes from Colombia and is shipped here to West Africa. A cost and not very environmentally friendly venture. We have plenty of plastic waste here and a strong economy built on the collection of plastic waste.  I would like to help direct that resource to classrooms at a fraction of the 9,000 dollars it costs to make (one classroom)  here. I know some of you have questioned the solidity of the classrooms or the comfort of the environment. It is actually quite cool in this very hot and humid climate. They do not use the bricks to support the roofing which is built on a hangar-like system that is supported on beams rooted to the concrete flooring. Does anyone have recommendations for how to start this business here? I recently saw that Hakkens added presses to his list of magical machines. Anyone interested in coming to help out with this project idea? Room and board will be provided in a loving vegetarian home. Oh, and yes, local governments and the UN agencies would be interested in paying for alternatives that use locally sourced waste.   am a program manager who dabbles in training of youth in wind energy when I am not engaged in conflict management activities in the region.
