Most biodegradable polymers are water-permeable (water intrusion is how bacteria get inside the material to break it down). Anything water-permeable is not appropriate for medical use, even as a wrapper for something else, because you can't guarantee that the thing inside is sterile.
There's several big tradeoffs there.
Glass is heavy compared to plastic, and also bulkier. A truck full of product in glass containers will carry substantially less product volume than if it were plastic containers. In order to distribute the equivalent amount of product, more trucks will have to make more trips. When you scale this up to national distribution you're talking about hundreds more trucks on the road, thousands more trips per year, which is going to have an environmental impact.
Glass is fragile compared to plastic. Some accounting is already done for product loss due to breakage during distribution, but plastic containers are fairly durable (part of the problem of course). If you switch to glass the loss percentage goes up, which again means you have to make more trips to distribute the same amount of product, so compounding the environmental impact.
What percentage of single use plastic is used for storing liquids? I would imagine it's a minority, with things like plastic bags making up the majority.
Plastic bottles are the most common type of container for fluids and make up a huge portion of plastic waste. Drinks, cooking oil and vinegar, cosmetics, personal hygiene products, cleaning products, motor oil, paints, medical products... and that's just the common consumer stuff. Plastic bags are a big part too but liquid bottles are certainly not a minority.
Plus very acidic liquids like soda may not be bio-active enough to cause this to break down, depending on what the process is.
You also have to be concerned about the outside of the container. Will it be washed as part of the production/handling process? Will sweat and bacteria from human hands cause it to start breaking down? It will be packed in a box for shipping, then unpacked at a store, then picked up and looked at by who knows how many people before being purchased, then it has to stay in one piece until the product it contains is used up. A bottle of toilet cleaner or shampoo or laundry detergent might be handled hundreds of times, and its lifespan from production to final disposal might be a year or more.

would that be... a pedigree?
Hmm, that's just a bunch of URLs, which is useful but not very readable.
Tineye found a much higher resolution version: https://imgur.com/gallery/reference-guide-p07BzW6 , but unfortunately the text still looks like shit - actually if you zoom in it looks like some shit AI processing was done to it. I was really hoping for something that would be legible when printed.
It's not printable, especially the list of convictions.
Y'all got any more a'them... pixels?
yeah, ha ha... "paranoid"
