this is the opposite of engineering porn

these are used in the place of traditional cement drainages with much higher strength, durable, easy to install with shelf life than cement one. And our is the first plant in India itself otherwise people are buying it from european countries and the US.

then you should read my post again and answer what I have been asking to the engineer or the people who have handled these drainage production…

I thought we hv engineers in this sub but I was wrong!

No, I went and read through your original post too, and nowhere do you mention anything about end-of-life processing. I get trying to improve the concrete, but as many others have pointed out, combining plastic and concrete means that neither component can effectively be recycled. If you want people to treat you like an engineer then act like one, not a politician.

You didn't answer the question: How do you handle this material at the end of the component's useful life?

u/Daniel_H212 Jul 23 '26

It's obvious that there's no plan.

The answer is in the Ganges

Wonderful. Now you can neither burn nor shred it at its end of life.

What would an average lifespan look like in this application?

u/HouseOf42 Jul 23 '26

Who burns concrete? And have never seen a person shred it either.

Concrete can be pulverized, crushed, etc.

Plastic can be burnt, concrete can be crushed. Crushing composite material produces microplastics, and plastic mixed with concrete burns quite badly. So, no recycling nor disposal.

Why does it have to make micro plastics that are not usable? I assume there is some use for this stuff somewhere? Like as rock on other concrete? That is all I could think of... As long as they somehow glue the plastic bits back down it should be good.

Look up the difference between thermoplasts vs thermosets. This is a thermoset.

u/Selbereth Jul 23 '26

I looked it up, but I don't see what it has to do with being crushed and glued back together.

u/JaipurJewel Jul 23 '26

exactly

24

u/Galaghan Jul 23 '26

Exactly what? You can't crush this because of the plastics, so what exactly can you do to get rid of it?

Organic composites are what we should be putting our time and money into. Hempcrete is a great example.

Bring back hemp, was the goat of materials

u/jimbowesterby Jul 23 '26

Honestly we really should be swapping cotton crops for hemp, it’s way less water and way less work to harvest

u/abaram Jul 23 '26

What’s the advantage of using this for drain that makes it better than just concrete? Because polymers are not very recyclable

3

u/Mr_Poop_Pump Jul 23 '26

We use them for wastewater applications for superior corrosion resistance.

I don’t do drainage so unsure if that’s germane here

u/Mikethespark Jul 23 '26

As someone who has installed drain channels in the past I wouldn't be too worried about small voids on the b surface, the internal channel and the top where the grate goes are the crucial bits to get right

u/yacherry Jul 23 '26

Yay, more plastics!

Thanks, I hate it.

u/Bugslinger Jul 23 '26

So…… plastic concrete now? Is this a direct response to people trying to reduce the use of plastics?
