To be honest I'm not sure which it is. I'm sure each manufacturer has their own composition of materials... But generally they're all recyclable. Most recycling places hear coroplast or alupanel and they don't know what it is, so it's easier to say no.
We had about 300 screenprinted coro
signs before remax changed their logo - they were all garbage and couldn't be used anymore. Called 4-5 recyclers and all said no. Then one finally said he's not sure, he'll look into it - he found the recycle code and said he'll take them. Out of.curioisity I called 2 of the others back with the code... And they said yes they do take them.
Sadly we haven't found anyone who can do alupanel. They market it as recyclable... And I believes there's ONE shop in the world who can do it. The others ask us to break the aluminum skins off the plastic and separate them, then They'll take it. An hour later... We just threw them all in the garbage.
Same with vinyl cores - we load them up by the skid and call a recycle company to come grab them. We get a 5ft high skid every two weeks... Costs us $20 a skid for them to come pick it up. It beats throwing them into the garbage... And that's another item no one would take... Until one saw the recyclable triangle with the code. Now they all will...
Canada may be different though. We have a couple recyclers every 10 km to make drop off easy. We have weekly pickups for anything plastic at our house for free. You actually get a $300 fine if they catch you throwing away a banana peel, let alone a plastic can. They make sure everything is as easy to recycle as possible, otherwise people would be protesting and pissed off at how strict they are with garbage and recycling.
