2 – 3 tons of polypropylene !!!
anyone idea what to do with 2 – 3 tons of polypropylene(PPR) and maybe more.
It is made of used indoor water pipes for hot and cold water. They are not clean inside – there is dried dirt overlay inside. And also some little dirt outside on surface.
Here is picture of particular pipes: https://imgur.com/yYHdb0g
I think that pre-shredding, shredding, cleaning in water bath/rotating barrel, melting(extrusion), cooling, cutting and selling granulate would be probably best idea. But, lot of investment is needed for this whole recycling process.
I dont even know how could i shred them, they are very firm and solid.
So then I found some local companies, which are buying plastic waste. But they offer very low price for it.
But imagine that quantinty, how much stuff could I make and create from it, but I have no machines, no tools – yet 🙂
I also had idea, if i could use final product as a string fillament for 3D printers, but i think it it not so flexible for this usage.
Wanna know your ideas and opinions.

Maybe you could saw them in smaller pieces and then directly melt them?
Another possibility would be to only melt some of them and use the pipe partwise. Qick idea: Melt down in a flat mould (outside in a old kitchen-oven) and then just set a 10cm part of pipe on it, should stick together and you have a plant-pot. I can also try to come up with more ideas, if you give me some measurements 😉
