Types of plastic

An overview of the different types of plastic, these are the most common ones. We mostly work with PP, HDPE, LDPE and PS. Just because we gather that the most from our waste here. However they should al work with our machines, just requires some (temperature) testing.

@plasticinabackpack
Meting PE bags in an regular oven is relatively safe to try with. Also ironing bags in many layers together can create stiff blocks of PE

@plasticinabackpack,
Unfortunately, it dense foam is made by thermossetting plastics and therefor not recyclable. It is not possible to make ‘foamy’ plastics with recyclable types.

HDPE does meet your requirements and is perfect for products like mallets, hammers etc

Does anyone have experience with shredding ABS from printers/copiers? jtravis recycled some of those ABS cases with a wood chipper but I wonder how well that goes with the precious plastic shredder. I have piles of it at my school but these things are quite hard. I suppose much depends on the power of the engine..

Hi Friends!

I’m working in a project to recycle a multilayer bags used to food packaging and more..
The problem is that when I try to melt it, it doesn’t work properly because some part melt good and other just burned.. Do you have any ideas how to fix this?

Thanks!

What about recycling plastic bags and film? Can these be recycled with this process??

Hey !
Can anyone tell me that what steel wire to use for the line tie / bait harness. From what I’ve been able to find, .024 to .028 is the popular size, and torsion straightened steel is preferred, is that correct?

Thanks in advance!

Yeah i feared for that… Lasercutting PVC is also a bad idea… There doesn’t seem to be any easy way to recycle that shit

@jostodgel, No problem, this is all open source like all of Precious Plastic. Better refer to here and credit PP than credit me.

@mathijsstroober those charts are great! I was wondering if you have published them anywhere else, and if they can be shared on a website with credit to you?

If you want to know anything about HDPE here’s an extremely comprehensive page including history, application, recycling, research etc. https://provprocure.com/hdpe-high-density-polyethylene/

Does the plastic strength decreases after melting or are there other material which are mixed with the plastic to maintain its strength.

Hi guys, just wanted to know if PP, PE and/or PS were suitable for 3D printers

@Mathijsstroober,
Thanks for the fast response, perhaps HDPE is the best material for my application! I’m making a wood frame backpack, however, the wood-to-wood glue joints seem to be the weak point. I thought that replacing the wood cross-members with a relatively stiff polymer (with an elastic range) might be the best option to prevent fractures from stress or big drops.

Any ideas on the best ways to learn about and get hands on experience with the PE’s?

Hi @Mathijsstroober,
Thanks for sharing these graphics! Curious if you have worked with or know any resources you could suggest for learning about turning a recycled plastic into a dense foam? I’d love to make or source a recycled plastic that is stiff but elastic enough to take some rough handling without fracturing.

Thanks for any help!
Josh

Hi, did anyone has an experience with HDPE? I would like to know about mechanical properties of recycled HDPE in comparison with virgin HDPE. Thanks.

What do you know about ?

World first bioplastic solution to growing coffee cup waste

I heard the oxo degradable plastic is not good.
Im working on helping restaurants go to alternatives.

Thanks,
