I've successfully fused mixed contaminated plastic

Hello Precious Plastic people!

My name is Khalid and I reside just outside of Edinburgh, Scotland, in the United Kingdom.

I began investigating the issue of plastic waste whilst trying to reduce my company’s recycling costs.

After many trials and research I’ve been able to fuse together dirty, mixed contaminated plastics into usable blocks.

I’ll shortly be crowd funding to commercialise this, giving away (FOR FREE) the lengths of extruded material as alternatives to precious timber or metal, reducing our environmental impact whilst diverting waste away from landfill.

The fused material is very strong and with a little colouring should turn into really solid black lengths, perfect for making outdoor furniture, fence posts, support beams and more.

I’ve uploaded an image showing what I’ve done so far.

wow nicely done!
It would be interesting to know more about it!
Do you use precious plastics machines?
When you say “contaminated”, with what is it contaminated?
And what kinds of plastics do you mix?
Thanks for sharing!!

Just wondering when you fused the plastics together have you tested for toxicity. i would be very interested in what you find out.

No I did it on a small scale using my own equipment, nothing fancy.

I mixed everything I could find;

– Cotton swabs
– Bottles
– Films
– Toothbrushes
– Packaging

The material was contaminated as it contained various non-plastic elements. For example the toothbrushes had toothpaste on them, the packaging food and the bottles liquid.

Have you done any tests on the resulting material, such as measuring it’s tensile strength? This would be useful if you want to propose it as an alternative to eg. timber or metal.

Not yet, but I can tell you its bloody strong!

It cuts with a hacksaw and takes some doing! I’ve drilled into it and hit it with a hammer.

I can definitely see the appeal, but i would say that the use would be limited to non structural applications, as there would be a quite a large difference in how it behaves from batch to canh, simply due to the fact that the exact makeup of the end material would vary quite a lot, and due to the fact that it is rather contaminated by dirt, degraded plastic and so on.
Not trying to shoot down the idea at all, i’m just hoping to add something to the conversation:)

Hi Kalhid, Fantastic technological innovation! Will you be making the process and fusing instructions open source ?

Well remember to clean your plastic!
Even companies who also mixes plastics are washing their materials, as you newer know the toxidity dangers of what is being mixed.
This will also affect your outcome, as @clementhempel also says.
Try only to mix your material if you have to. Like when recykling products that is made of parts from different types of plastic, BUT SORT THE PLASTIC WHEN YOU CAN!
The plastic you are fusing can not be recykled again easily, and you will not help the envioment that much.

Please do alot of research before going on with this

Good luck
