I've searched the internet and couldn't find a specific answer. There doesn't seem to be a single recycling company that takes empty silicone tubes (also know as mastic tubes) and recycles them. As a result, here in the UK it goes to landfill. Such a shame and doesn't seem right!
The tube is made from HDPE but is contaminated with the silicone inside it, usually used for sealing windows or bathrooms.
There is a chemical solution available that will strip out the silicone by dissolving it but that doesn't make commercial sense for two reasons;
- The cost and time involved
- You are left with a chemical to dispose of
Nobody wants these tubes and it has begun to annoy me!
I'm wondering if anyone could advise of the possibility / dangers of simply melting the empty tubes which result in a plastic mix of HDPE and silicone?
Would it work? Could it work?
