    Even 50 days is relatively fine if it’s cheap enough to replace saran wrap for food products

    well we already have that

    and that’s 50 days total, so those big commercial rolls of plastic wrap are much harder because they’re now perishable too: you can’t just stock a warehouse up

      I went and read the paper, but the TLDR is:

      • The bioplastic is a rigid material with high tensile strength a bit higher than conventional rigid plastics
      • Made from acidic solvents to create a gel consisting of cellulose
      • Can be closed loop recycled by redissolving with the same solvent
      • Depends on soil microbials to break down the cellulose within 50 days
      • Cost analysis presented it at 2.3k usd per ton, with the cheapest plastic (HIPS) at 1.3k/t and the most expensive (PLA) at 2.6k/t. Though the cost analysis didn’t show all the plastics it used for material comparison.

      You can basically think of it as a fancy wood structure, since it’s primarily cellulose.
