I did but I think I got away with it.
what are you showing me here?
Er hate to break it to you but those are wheels not frames
Stockpiling 26" wheels for when they make a comeback
If you click on that photo stream, the previous photo is a pile of carbon frames 😥
Are those wheels that failed quality control waiting to be dumped into landfill somewhere?
Makes you wonder about the effect our leisure pastime will be having on future generations.
World hula hoop King wishes he'd kept his "bestest" hoop, and now can't find it????

But everyone knows Chinese carbon has no QC.

Presumably they incinerate it. You can also recycle the carbon into other uses, like the reinforced plastics used in injection moulding.

They should bury it, if dinosaurs 'n' shit can make oil, imagine the awesome stuff carbonz will create in a few million years!!
it will turn into diamondz innit
I don't really have a good feel for how polluting carbon fibre is. Kind of understand (roughly) the process and the energy involved in mining iron ore, making steel and producing a frame. Also understand how it can be recycled.
But have no idea for carbon.

Yeah, but cheap stuff is teh coolnezz. Where's the cheapest I can get some ENVE wheels? Don't care if they're faked, knocked up in some dirty little sweatshop by little slave kids. I just want cheap stuff. NOW, DAMMIT.
😐
In order to re-use carbon, you first have to burn off the resin, then chop the fibre strands. Carbon is a horrendous material when it comes to end of life.
Really concerns me where automotive firms are now getting excited about using carbon in body panels - sort of hoped they'd remember the problems with piles of scrap Trabant shells.....
Whereas I visited a foundry and there was a huge pile of steel scrap trucked in to go straight in the pot.
And an aluminium extrusion plant where they had a remelt facility for ALL of their scrap.
I though carbon frames were about 95% recyclable - could be wrong.
People are concerned about the environmental impact of carbon bike frames...really?
Compared to what else is happening?

Better than being stuck to Oxygen in the atmosphere?

In theory perhaps but cost of doing anything with them is prohibitive. IMO steel or Alu is better value as it lasts much longer
Those frames/wheels are piled up for future sale/use, no ?
Environmental impact is relative when it comes to engineering materials, steel and aluminium alloys aren't exactly noted for being green choices...
yes the visual of a massive pile of rejected carbon parts is a great way to illustrate waste, it might also be viewed as demonstration that QC inspections are effective at this particular factory?
Recycling most materials is uneconomic, hence all the landfill, basically you can't have it both ways, either you get low impact products with minimal wastage at a premium, or you can pay less but help stamp all over the planet... What's your [u]honest[/u] preference?
Yeah for all we know that's 10 years worth of rejects.
And I'm encouraged to see evidence of a QC process.
Might also give a hint why carbon is so pricey, if there is a higher reject rate then other materials. Not that you can conclude that from a couple of pictures with no context of course

It's a nice sentiment but seeing as each of us here emits over ten tons of CO2 into the atmosphere a year it's a fraction of a small drop in a big ocean!
This isn't the tip, this is the stockroom. This is where your ebay carbon stuff comes from 😛

😆
Trees eat CO2. Could we just feed carbon frames to trees? 😀
(yeah, I know it's C not CO2 😉 - and a pile of resin ).
I always wondered what Hora's back garden looked like.

IIRC the only material that's economic to recycle (and by inference as money = energy, the only one that makes sense from a CO2 perspective) is glass. Which ironically is a material best suited to be re-used, but for some reason we melt it down and make new bottles rather than just washing them.
And even after that, your car emits more CO2 driving to the bottle bank, than would be saved by recycling a crate of bottles.

Early contender for post of the week.
Bloody hell Rotherham has cleaned itself up.

I think you're confusing CO2 and methane 😳It's a nice sentiment but seeing as each of us here emits over ten tons of CO2 into the atmosphere a year it's a fraction of a small drop in a big ocean!
If you're producing ten tons of methane you should go to the doctor!
To answer cookieaa my honest answer would be to pay a premium for environmentally sound products - I'd be suprised if that wasn't a fairly common viewpoint from most on this forum. Also, if one material was shown to me to be vastly worse on the environment than another similar performing one then I would stop buying the former.
Many people on here (myself included) seem to be ignorant of the issues surrounding carbon reuse. This is something that needs addressing - something that I would actually by a magazine like Singletrack to read about. Sadly such an article would probably sit badly with the companies that fund such magazines....

My local council says glass we chuck in the recycling bin generally gets crushed up and stuck into road aggregate. Can't see that being very environmentally friendly. One time reuse rather than constant recycling as glass, and goes towards building more roads, thus more CO2.

I thought these tea party/ telegraph myths had been dispelled
