This is a legit method for building small things like that where you can use the brick-like shape of the bag when it’s hardened. You just need to make sure the concrete gets soaked all the way through with a hose or rain.
There’s a bit of plastic in there somewhere probably, but the bags are usually burlap. It may also be special paper depending on where you get it from.
Lots of revetments for water control in South Florida were built like this in the past. The burlap sacks all eroded away and leave an interesting pattern like you mentioned.
There’s a park on the lake near me that has a retaining wall that steps down into the lake swimming area built this way. The bags are rotted away so they’re just concrete pillows now. They’re been there at least 20 years
That’s exactly how I built a retaining wall at my last house. It had rotting railroad ties that I got rid of and I just stacked bags of concrete before it rained. The concrete set, the bags degraded, and I had a cool retaining wall in my back yard.

In like 10 years when the bags have all eroded away it’ll also leave a neat look formation I’d bet lol
A state park near me did this with a giant set of stairs.
Looks neat. Is awful to walk down.
Plus as a bonus a lot of micro plastics straight into nature. Neato!
Aren’t the bags paper based?

Pretty sure all the packaging was just papier
I hate to break it to you, but concrete isn’t good for the environment either.
