Do you store your hay outside? I have a neighbor who still uses sisal twine. It looks like they have considerable more waste per bale than we do.A nearby county had a recycling grant for a few years. Evidently only myself and a couple other farmers took advantage. I haul about 70% to the landfill.
I have completely returned to sisal twine. I was tired of plastic twine wrapped on axles and beaters.
There was some development of bio-degradable bale film and also an edible type. I have not seen that brought to market though.

We used to have a twine only baler. We store 85% of our hay outside. When we replaced the baler with one that does cover edge net wrap the bales seem to shed rain a lot better. But storing inside is still better.I'm lucky in that I can store a fair amount of good hay under roof. If you are comparing net wrap to twine than I would agree, net wrap (Some brands) do a nice job of shedding moisture and maintaining bale shape which can really help prevent storage rot/waste. Comparing sisal to plastic twine I've seen no difference in storage rot/waste (I have a twine only baler and do store cornstalks and grass hay outside -- my bale wrap experience is limited to purchased hay and discussions with neighbors).
One benefit to sisal is I don't have to cut the twine anymore (It's rotted through), so I can just pull off all the twine before putting the bale in my feeders. Efficiency! haha
