This is a bit misleading. First off, there's a difference between flex pvc and rigid pvc. Flex pvc shouldn't be used around birds. There's also different grades of pvc. Most PVC includes heavy metals like lead. Whereas the PVC that I use for my stands is furniture-grade, rigid, lead and heavy metal-free and manufactured in Florida. This kind of pvc is rarely found in stores, but is easily found online.I love the wooden stands. It's my preference. I know a lot of items are made out of PVC but not all are created equal. Because we use PVC pipes in our aquaponic systems, I did a lot of research on PVC piping and what type to get. Here is what I found about PVC:
But, from both an environmental and health standpoint, PVC is the most toxic plastic. Here's why: Vinyl chloride, the chemical used to make PVC, is a known human carcinogen, according to the World Health Organization's International Agency for Research on Cancer (IARC).Feb 22, 2013
Manufacture and Disposal Concerns. The manufacture and disposal of PVC creates potent environmental toxins. Polyvinyl chloride, the main ingredient of PVC pipe, is classified as a known human carcinogen. ... This is also a problem during building fires, where exposure to burning PVC puts firefighters at risk.
Wood, has none of that once it's been cleaned, cured and ready to use. As long as you know where the wood came from and has nothing dangerous, it's natural and if the birds chew on it, so what. PVC on the other hand makes me nervous unless I know who manufactured it and where. Food grade is what I always go for.
Oh, of course! I agree completely, I just wanted to give some nuance to the issue. PVC is a great and easy way to build playstands, so I'd hate for people to swear it off completely when there are safe options available.Thanks Matto for clarifying. I know there are different types of PVC and I'm no expert by any means. I do know that there are PVC pipes that are okay for human grade. I wasn't trying to put your stands at risk and just knowing the differences obviously makes your play stands safe.
Not all are like you Matto! A lot of people think they can just run down to the hardware store and get whatever PVC and use it. They shouldn't. Just like wood, some of poisonous for birds. We have used many different types of PVC for human grade consumption for testing, not many passed but due to $$ being made they just keep selling it thinking that it will be used for pipes where no one will be chewing it or playing with it.
We were concerned because whatever comes out of these will contaminate our food source. That to me is unacceptable. We've seen it first hand when the plants in our aquaponics unit (by the way we use PVC in our unit) not doing well after installing a new pipe somewhere, we found that certain PVC pipes are much better than others.
Thanks for letting us know what you use. It helps relax my heart a lot!
@Laylatoo where did you get the round rope atom toy on the middle play stand? It is very cool.
