Judith, you may want to ask around locally.
Pay attention to what business handle a lot of produce or other materials that come in bags. Think about grocery stores, farmers/ranchers, resturants, school kitchens, and places like that. You might find a local source of used bags. While I doubt you will find much in the way of used tubes, you can still use the bags in the same way. The key would be to find a local supply of enough netting style bags and get them to save the bags for you.
It is best if the bags are kept out of sunlight. The UV radiation can cause them to break down and become weak. Don't neglect the details such as where your source of bags will be storing them until you pick them up. If the bags are just tossed into a bin outside and exposed, the bags may be worthless before you get them.

Maybe you would need a huge amount of the knit raschal. I don't know how to estimate that. Anyway, I like the idea and would give it a try. You would have to make domes with it though or the walls would fall in without some sort of buttress. If I could get some of the knit stuff easily I would probably try it for a garden wall filling the first course with pumice in stead of papercrete. the video has good music.
