Pepsi Moving To Bottles Made of Plant Material 321

Master Moose writes "Pepsi unveiled a new bottle yesterday made entirely of plant material. The bottle is made from switch grass, pine bark, corn husks and other materials. Ultimately, Pepsi plans to also use orange peels, oat hulls, potato scraps and other leftovers from its food business. 'This is the beginning of the end of petroleum-based plastics,' said Allen Hershkowitz, a senior scientist with the Natural Resources Defence Council and director of its waste management project. 'When you have a company of this size making a commitment to a plant-based plastic, the market is going to respond.'"

    A quite renewable resource; recycles well; doesn't make your drink smell like a chemical factory over time.

    I hope after these biodegradable plastic-like-plant-chemicals (that'll probably leech into your soft drink when/if the bottle gets warm), they consider glass as a material for soft drink bottle containers.

      Glass is heavy and fragile and bulky and I would bet uses more energy to produce and to recycle than PET. Nothing is going to leach that isn't already. PET is PET. It's the same chemical produced from a different feedstock.

        • My father-in-law used to run a Coca-cola plant. They went away from glass bottles because of the automated process that fills them.

          Glass bottles not only have to be collected from the stores (instead of getting a regular shipment from the plastic factory), they also tend to acquire chips and scratches. So they have to be inspected.

          But sometimes those ships are hard to see, or just structurally weak without any visible sign, and they break when they go through the automatic filling/capping machine. And then

There is not enough of a market to sell 30 kinds of soft drinks, so they have 3 (maybe 4 in some places if they include dimpled sprite) choices; flavored fanta drinks, and regular coke (the one made with real sugar).

      Glass isn't that great for recycling. IIRC from my National Geographic issue a few years ago, recycled glass only uses 5% less energy to make than new glass. Compare that to aluminum where the recycled product uses 95% less energy to produce than from virgin materials. If you're looking to have a highly-recyclable product then aluminum is the way to go. Where glass is good is when you're reusing, but that brings up a whole question of logistics. Glass also has the issue of shipping weight and broken bottle

        That's the wrong stat to be looking at. Recycled aluminum uses much less energy than producing new aluminum because aluminum production requires huge amounts of energy. So aluminum may only require 5% of its creation energy to recycle, but that's 5% of a huge number. Glass' 95% to recycle is 95% of a small number.

        You want to be comparing the raw amount of energy needed to recycle. How many joules for a glass bottle, how many joules for an aluminum can.

      • That percentage doesnt mean much. How much energy does it take to recycle aluminum? How much energy does it take to recycle glass? If the former is more than the latter, the fact that its "only 5%" is irrelevant.

        Glass degrades by the same process as stone. It will, over time, be worn down. More importantly, it is chemically neutral in nature and not easily mistaken for food.

            Yeah, I'm reflexively skeptical about extravagant energy-saving claims when I hear them, but I agree, the article you referenced reads more like a press release than a study from the beginning. It gets really clear when you get to this part:

            Ok, some glaring red flags there: 1) "a study by CNW Marketing" (nuff said), and 2) expected Prius lifespan of 100k miles vs. 300k for a Hummer... really? Hummers come with a 5/100,000 powertrain warranty. Priuses come with a 5/60,000 powertrain and a 96/100k hybrid syst

      How do we dispose of them? Are they as recyclable as petroleum-based plastics? Also, are they biodegradable?

      According to the article: "Pepsi says it is the world's first bottle of a common type of plastic called PET made entirely of plant materials." PET, Polyethylene terephthalate [wikipedia.org], made from petroleum or from food waste is still the same molecule. It should perform the same regardless of what it is made from.

    • by slapout ( 93640 )

      That problem solves itself -- no one actually drinks Pepsi.

  • The source of the original material is just one part of the equation. Just as important to anybody who cares about the environment is how efficiently the product can be recycled, and whether or not it biodegrades at a reasonable rate. The article mentions neither, and so I'll ask here. Is Pepsi's new bottle as good or better than existing plastics in this area, or are we improving in one area for either marketing and financial reasons, at the detriment of others that are equally important?
  • Trading plastic bottles made from petroleum for plastic bottles made from FOOD isn't much of a win. The end product is the EXACT SAME PLASTIC that we're filling up landfills with right now, just made from food sources. Well done Pepsi...you missed the point entirely, but I'm confident you can still spin it into a positive to the organic/vegan/hippie crowd.

      No, this is still a major improvement. Less oil usage is good. Less food waste in landfills is good. Less dependency on foreign oil is good, at least for the US's economy. Hell, just because of that, you get minor reductions in income, and thus political power, to a variety of less-than-wholesome Middle-East countries. Major? No. A step forward? Hells yes.

      Besides, in case you hadn't noticed, plastic is recyclable. I've got an empty bottle of Mt. Dew sitting beside me - it's going into the recycle bin literally as soon as I finish typing this. No landfill usage at all.
      • Less oil usage is good.

        Is this true? The less oil that goes into plastics, the cheaper it becomes, and the longer it will take for economic pressures to force the world into a renewable electric-based regime. What's more, more of that oil will be refined and burned, rather than processed into plastics and buried.

        • this is almost a jevons paradox.

          still, plastic amounts to only 5% of petroleum usage (in US). once plastic has enough relative petroleum-share to really matter, we'll probably be well on our way to alternative fuels as well.

        • Excellent example that proves my point!

        Are you sure about that? How much more energy is it going to take to make these? If it's more, then where is that energy coming from? Are the raw materials heavier to transport than the current ones? What waste by-products are produced in doing this? What can be done with those by-products?

        I don't know the answers to any of these questions. Before you make statements like you did, you may want to look into these, and many other questions first. The end result may be that they use even more petroleum products than the current containers. Or create toxic leftovers in the process.

        Are you old enough to remember the styrofoam clam-shells McDonalds sandwiches were served in? Those were just "evil" according to environmentalists. Except they kept you food warmer and could be recycled into all kinds of things. But they were replaced by wax coated paper that could not be recycled. The environmentalists were happier with the paper that could go nowhere other than a landfill and the food is not only crappy, but gets cold even sooner.

          [citation needed]

          Styrofoam (which actually is AFAIK not technically what these were, and I don't mean brand-name-wise, but it's what people call that kind of foam) seems to be one of the HARDER things to recycle.. and food contaminated products (except for bottles & cans) seems to not be recyclable either.

          While it's not foam, even pizza boxes for example can't be recycled because they're food contaminated.

          Virtually nobody recycles styrofoam, which makes it pretty much the same is if it could not be recycled. The reason is that it takes a huge amount of space for its weight so it is expensive to carry. I agree that styrofoam keeps your food warmer, but it is not greener than wax paper.

The full array of consequences is always going to be mixed at best. Ult

And PET containers are imminently recyclable, and the entire idea is PRACTICAL and economically feasible, which puts it far ahead of the game from most foolishly impractical eco-nut ideas.

        This *is* /., where foolishly impractical will be on the desktop next year, for sure, this time.

    • could be helpful in the long run. since plastics account for ~5% of petroleum consumption, the market is driven by petroleum-as-fuel. once the market responds to that, there may be very little left for plastics. there are fuel alternatives in development, so it should be just as important to develop alternative feedstocks for plastic (something we're, at least, behind in, leaving aside whether it is even possible in all cases).

    • The base resource the new bottles are made from is waste they previously paid to throw away, now it's useful and customers pay to take it away. That's a win. It also reduces the effects of higher oil prices, as they don't use it (as much) anymore.
    • Is it FOOD or is it food-waste? If it's stuff that would be thrown away otherwise (and not fed to animals perhaps), then I still think it would be 'less bad' than oil-based plastics.. and yes, I did see other responses already denying it would be good to use less oil for this purpose.
