from the snap,-crinkle,-and-poop dept.

The University of Nottingham:

Using a special technical approach, the team is working on plastic films derived from konjac flour and starch, cellulose or proteins that are fully edible and harmless if accidentally eaten by people or animals—unlike health issues associated with microplastics and other plastic waste that make their way into the food chain.

The researchers have found that plant carbohydrate and protein macromolecules bond together into a special network structure during the film-forming process. The network structure provides the film with a required mechanical strength and transparent appearance for the film to be used as packaging materials.

The idea is to reduce incidence of plastic in the environment.

    Having edible packaging not only is good for the environment, but once Monsanto's plan is complete and the environment can no longer produce any kind of food, we will at least be able to eat the packaging. But maybe that is also part of the larger plan.

      How well does it hold up to bacteria, fungus, or mould?
      Or have we simply forgotten the purpose of wrapping food?

      IMHO attacking the massive OVER PACKAGING of things would be a much MUCH more productive start, but then that doesnt create a profit center for anyone.

      We are banning supermarket plastic bags, and yet we still happily buy a big bad of chips containing a dozen small bags each containing about a dozen chips for kids school lunches.
      We are drinking out coffee made from plastic single use, usually throwaway potlets of ground coffee.
      I watch people pick up a bunch of bananas in the supermarket and double-bag it in the fruit+veg tearoff bags, then put it in their environmentally sound reusable shopping bag..

      Plastic is a huge advantage for some food safety, but marketing and 'convenience' has created a packaging monster, that is the problem.

        Solution: employ people to remove the excessive packaging and repackage in something simpler. This can either be done as a post-production step at the product producer, or as an intake step at supermarkets.

        If enough thought is put into it, there must be a way to get the government to pay for a program like this.

                There's no total reduction of entropy.
                To live, an organism needs to increase the entropy of the environment more than the reduction of entropy necessary to maintain the life.
                Extinguishing other life forms unnecessarily (e.g. by poisoning the env with plastics) runs contrary to the purpose.

        It's biodegradable, so YMMV.
        I assume it's safe for some time and if you keep it dry, but inevitable it will absorb some water and allow the bio- to -degrade it.

        Since it's digestible by humans, I suspect it's quite energy rich for microbes/fungi. I mean, look, microbes are able to break down cellulose and chitin as a food source, humans can't

      They say you can eat without troubles (thus, you should be able to digest it). Which means a couple of hours in a warm and wet environment should transform it in some kind of goo.

      https://en.wikipedia.org/wiki/Cellophane [wikipedia.org]

      Cellophane sales have dwindled since the 1960s, due to alternative packaging options. The polluting effects of carbon disulfide and other by-products of the process used to make viscose may have also contributed to this; however, cellophane itself is 100% biodegradable, and that has increased its popularity as a food wrapping.

      [...] Cellophane is biodegradable, but highly toxic carbon disulfide is used in most cellophane production. Viscose factories vary widely in the amount of CS2 they expose their workers to, and most give no information about their quantitative safety limits or how well they keep to them.

      It's still around. I remember it as the main packaging for stuff like crackers and candy until companies started to use the plastic film from dead dinosaurs in the late 50's and early 60's. It is rather stiff and hard to reuse so fell out of favor against cling wrap and plastic bags.

    The idea is to reduce incidence of plastic in the environment.

    Before plastic became common, with the consequence of megaplastic, macroplastic, and microplastic pollution and associated ills, what packaging did humankind use, and what were the consequences?

    The following packaging materials are considered on their own merits. Consider that they can be produced with or without adding solvents, coatings, and/or preservatives that are themselves envrio-evil:

    Wood: Is recyclable, reusable, and a naturally biodegradable fertilizer. Toxic or poisonous: No
    Glass: Is a recyclable, reusable natural mineral, another form of sand. Toxic or poisonous: No (inert) (unless it's still sharp)
    Rock, Stone, Etc.: Recyclable, reusable natural minerals. Toxic or poisonous: No (inert)
    Paper ranging from tissue to paper with or without wax to cardboard to corrugated fiberboard: Is recyclable and is a naturally biodegradable fertilizer. Toxic or poisonous: No
    Metal containers made from metals such as aluminum or tin: Are metals from the earth, easily recyclable and returned to the earth if discarded. Toxic or poisonous: No
    Metal foils such as aluminum or tin: Are metals from the earth, easily recyclable and returned to the earth if discarded. Toxic or poisonous: No
    Cellophane: So named because it's made of cellulose, a natural fiber from things like wood. Is recyclable and is a naturally biodegradable fertilizer. Toxic or poisonous: No (Note: The team is working on a film derived from cellulose? There is material here that could be studied towards that end.)

    Now, before plastics became widespread, perhaps 50 - 60 years ago, these were leading packing and packaging materials for somewhere between 10,000 and 10,000,000 years of human packing and packaging history.

    Sure plastics have advantages, but the fact that plastic is simultaneously also so disadvantageous that people are cooking up konjac flour cling film is a sign that perhaps we as a packing and packaging society might need to rethink our default go-to packing materials.

        Aluminum and other metals are energy-consuming to recycle.

        Aluminum is even more energy consuming to produce than it is to recycle. To recycle it all you have to do is melt it. It takes even more energy to produce than to melt. Hence it is profitable to recycle aluminum. Enough so that you can get paid by the pound for aluminum.

        That's kind of like the argument one hears sometimes of "Oh yeah? Well electric cars might be emissions-free but lots of the electricity comes from coal so the cars are very polluting to the atmosphere!" No, the cars aren't polluting the atmosphere--in fact those cars can be emissions-free and hydrocarbon-fuel vehicles can't, ever. You can combine emissions-free vehicles and charging them on green energy and get your emissions-free transportation; there's no law that says you have to add coal.

        In the same way, these materials aren't polluting, massively or otherwise. In fact, these materials can be pollution-free, and plastic can't, ever. You can combine these materials and non-pollution-introducing manufacturing methods and get your non-polluting materials; there's no law that says you have to manufacture them in environmentally hazardous ways.

        I point this out in the sentence before the list begins.

        Sure, you can make rainbows and sunshine "evil pollutants" in this way by adding carcinogens and spent nuclear fuel--that doesn't make rainbows and sunshine bad things, it just makes you inept at environmental conservation. Blaming the rainbows and sunshine for "being massively polluting" when what they actually are is "massively polluted" kind of misses the point of this exercise.

    It's not just photosynthesis: if you throw them on the ground or in the ocean, they will compost. They work just fine for wrapping food in.

    A while back I read that street vendors in Thailand used to wrap their food in banana leaves. Their clientele thus grew accustomed to throwing the leaves on the ground, where they never caused any problems. But when those vendors commenced using plastic wrap, there was a substantial littering problem.
