Unfortunately, you can safely assume all of your plastic and rubber is a petroleum derivative that has been rendered non-biodegradable unless it's advertised otherwise.
Patagonia does a lot of stuff with natural rubber. I think it's cool, but you'll definitely notice it in the price tag.
The NHL All-Star jerseys from last year were largely made of recycled plastic crap from the ocean. They were actually made by Adidas, now that I think of it. I think that's a good way to go for materials with a smaller footprint, especially mesh-like stuff that can be made from woven garbage essentially.
Kinda off-topic but..
Something I've noticed is that ppl say and use the word plastic like there's only 1 type of plastic. It's probably more like thousands of chemical compounds that fall in the plastics family.
I don't think recycling is really gonna be a big help. The problem is our global overuse of petrochemicals. This overuse of plastics and their uncontrolled release into the environment is the disease.. Recycling just helps correct a symptom of this disease.. Same with cleaning up our oceans and beaches.. The disease persists..
Plus that shit is usually just 5% recycled material. Trust me, 5% ain't shit. I could cut 5% off of YOU and you'd likely survive. Fuckin 5%!!
Maybe some brands do more, honestly don't pay too much attention to plastic clothes.
And biodegradable? Degrades into what? I'm guessing a bunch of yummy yummy chemicals that seep into the environment and work their way up the food chain. Great. I've always thought fish should taste more plasticy.
Don't believe me about overuse?
Try to do a day without plastic. Or rubber..
This could mean no clothes, shoes, phone, computer, skateboard, lights switches, bank card, food, water..
It's either made of plastic or had to touch plastic to get to you..
Water? Most pipes are plastic now, and the cartridge in faucets is made of plastic.
Seriously. Just try *thinking* about 1 day without plastics..
