Scientists Discover a Way To Get Every Last Drop of Ketchup Out of the Bottle (bbc.com) 181

Posted by BeauHD from the karate-chop dept.
Slashdot reader schwit1 quotes a report from BBC: Scientists in Boston have found a way to get every last drop of ketchup out of the bottle. They have developed a coating that makes bottle interiors super slippery. The coating can also be used to make it easier to squeeze out the contents of other containers, such as those holding toothpaste, cosmetics and even glue. The researchers at the Massachusetts Institute of Technology (MIT) believe that their innovation could dramatically reduce waste. In its manufacture, the container must first be coated on the inside with a rough surface. A very thin layer is then placed over this. And, finally, a liquid is added that fills in any troughs to form a very slippery surface -- like an oily floor. The ketchup hovers on top and just glides out of the bottle. According to Prof Kripa Varanasi, who developed the slippery surface, the technology is completely safe. "The cool thing about it is that because the coating is a composite of solid and liquid, it can be tailored to the product. So for food, we make the coating out of food-based materials and so you can actually eat it."

schwit1 adds: "Pretty slick."

    • You're absolutely right. This is something that is 100% in the consumer's interest, which means it'll only happen if the manufacturer is legally obligated to use it.

      • Actually its not. The most savings could come in the manufacturing side that uses huge vats of ingredients. Those vats need to be cleaned and the losses are much larger than on the consumer end.

          As a percentage, the losses on those large vats are tiny compared to the customer end. It also seems unlikely that this coating would survive a proper cleaning, and re-applying it for each batch would likely cost far more than the product loss in the cleaning process.

          • You would be wrong. Its on the manufacturing side real savings will occur. Understand they talk about ketchup because it does just this, gets people talking about their product. Ketchup doesn't matter in their plan other than to help secure funding. There are processes that may or may not be food related where 10+% of product is lost due to the viscosity of the product. In fact the purpose of this money raising is to invest in their CleanTanX product line.

      It is definitely unsatisfying when there is something in the bottle you cannot access.

      In fact there is no doubt people want to be able to squeeze every last drop of bottles. The real question is : how much are they ready to pay for it? The answer to this question will tell if manufacturers are interested or not.

      Manufacturers can easily work around that. They'll just sell smaller bottles.

      The 64oz bottle will now be the 62oz bottle and the 32oz bottle will become the 30oz bottle. They can make the label a little larger and it'll barely be noticeable, while people get the thrill out of getting every last ounce of ketchup.

      • Don't do much shopping do you? lol the bottles,packages have been getting smaller and smaller by the year instead of raising the price they make a few oz smaller package for more profits because now you need to buy 2 to get as much as the 1 package.cereal boxes are smaller,pasta boxes are smaller,spaghetti sauce bottles are smaller all by a few oz. ect ect.

          I've been noticing that, especially with orange juice. The half gallon is now slightly less... I lived overseas for a decade while I think it was starting to happen, so it was sort of a shock to me when I returned to the U.S. to find that.

          That's why I brought it up as the solution to the OP's idea that it wouldn't work if people can now get the full amount out. The manufacturer's will just reduce the full amount and keep the price the same.

    • You're doing it wrong then.

      Heinz could sell a quality empty bottle with the slippery surface, and then sell refills for it like they do for restaurants... A big plastic bag of Ketchup. They get to profit from the sales of the bottles, plus they save on the refillable packaging. The consumer thinks they are getting a good deal, but really, there might be some wasted food from the refill bag.

      For the cost to manufacture, I totally agree. And it's the hearth of the problem.How much it cost per ketchup plastic bottle? I've read about ~2 cents with a quick google search.

    Rather than working on ways to continue the level of waste we produce, why not make more products refillable? Toothpaste, lotion, ointments, whatever. Instead of putting them in the same old plastic squeeze tubes put them in serine-like tubes than can be opened, cleaned out and refilled. The was a high end toothpaste called Rembrandt that came in an upright bottle that when you push down on it the paste would dispense from the top. The bottle was hard plastic that was made of two parts. It wasn't refillable but it didn't seem like a stretch to make it so. I can see taking the empty container back to the store to be refilled for less then the full price. Reduce and save money.

      Refillable packaging is a liability nightmare, so that is not going to happen. I'd just like to see non-recyclable plastic things outlawed, period. No making anything out of plastic and selling it into a market where it cannot be recycled. Glass was good because sand is an endlessly renewable resource. You can literally just take the glass out into the ocean and dump it. If you avoid toxic additives in the glass (and there are some, and there are alternatives) then there is basically zero environmental impact. The glass, in fact, turns back into sand over time. Recycling glass is a boondoggle — you really don't save any energy vs. making virgin glass. Meanwhile, all plastic bottles leach toxics into their contents.

    • Occasionally, aerosol cans of toothpaste have come on the market. Don't confuse it with shaving creme.
  • Manufacturers make money by selling stuff, repeatedly. The fact that you buy a bottle of ketchup and that you cannot use every last drop of it is your problem, not the manufacturers. In fact, if you could use more of what you bought then you would buy less of it and that means in economic terms that (a) consumer gets more product, (b) manufacturer gets less revenue *and* more costs as they now need to coat the inside of the bottle.

      I'm honestly not coming up with any use that would make sense.
      Consumer goods, it would be amazing, but as you point out, nobody would ever increase their manufacturing costs to decrease their sales.
      Industrial processes, first of all, large vats, pipelines, etc have far less loss (as a percentage) than small bottles and tubes that consumers use, but beyond that, the odds are it would need to be re-applied after each cleaning, which would more than negate the cost savings of less product waste.

      Some people (like me) whose parents grew up during wartime or similar were brought up to think exactly that. A bit of water in the bottle, shake it up and throw it in when making pasta sauce or similar calms that irrational food wasting guilt by getting the last bit out of a normal bottle.
