New barrier-coated PET bottle for high-acid aseptic beverage is recyclable
Reportedly among the first of its kind in North America, a new organic beverage from Tenaya uses a bottle with a barrier coating that is easily removed for recycling.
Tenaya LLC, Chicago, has introduced MADE® beverages in Ball Corp.’s 16-oz PET bottles with Plasmax® barrier coating from KHS. MADE beverages are filled at Kan-Pak, LLC, Arkansas City, KS, and are reportedly among the first high-acid, shelf-stable beverages aseptically filled in PET bottles in North America.
"The entire Tenaya team shares a philosophy and a vision about how to develop products that are better for the earth, good for the company, and good for people, and we do our part to support the overall health of the environment," says Charley Snell, Tenaya founder and former executive of Nestlé USA.
"We strive for environmentally friendly production and packaging. To that end, our current products are uniquely created and packaged aseptically to allow for shelf-stable storage with no need for preservatives or refrigeration, reducing the environmental impact of shipping and storage. We chose Ball's Plasmax-coated PET bottles because the bottles are 100-percent recyclable and widely accepted for recycling, and the Plasmax barrier is highly compatible with the aseptic filling process," Snell adds.
A Ball press release notes, “the term ‘aseptic’ means ‘free of pathogenic organisms,’ and the aseptic filling process removes all organisms that can cause spoilage, without impacting flavor or nutrition. The end result is an aseptically packaged beverage that can be safely shipped and stored for up to six months, without preservatives or refrigeration.”
According to Tenaya, MADE is a certified organic, all-natural line of beverages that combines green tea and fruit juices with refreshing floral and herbal extracts. It is available in eight varieties: Strawberry Lemonade, Pomegranate Mojito, Blackberry Peach, Cranberry Limeade, Strawberry Mojito, Pomegranate Lemonade, Raspberry Peach, and Blueberry Lemonade.
Ball describes Plasmaxas “an ultra-thin, commercially proven, transparent, internal silicon oxide barrier coating technology that protects the beverage inside the bottle from oxygen ingress and also prevents the PET from absorbing the sterilizing agent used inside of the bottles as part of the aseptic filling process. Unlike many other PET barriers, Plasmax is easily removed during the PET recycling process and as a result does not contaminate the recycled PET. Finally, because the barrier does not degrade over time, the length of time bottle inventory can be stored is not limited by the barrier material.”

Ladies and Gentlemen of the recycling world:
Again another great step forward in the efforts to stop recycling of P.E.T.
When will these "Barrier" technology developers understand that to increase the recycling process we need to be able to reduce the costs of operations.
Silcon and PET do not mix, therefore the cost to separate will increase. Making recycling PET more expensive or reduce the quality of the r-PET material so that it can not be used in Bottle to Bottle or Bottle to Sheet process. Even now, more and more of the fiber companies that purchase r-PET inform me that the quality of r-PET is getting worst.
This is amazing as new technology for washing PET is coming on stream, better whole sorting technology, and investment in final flake inspection increases.
I am sorry, but, this is bad news for recyclers, just like the groups that want to use PLA labels on PET bottles, absolutely senseless!
Please will all you marketing people, take a look at the long term recycling and sustainable prespective, and stop dumping your trash on those that are trying to make sustainability a reality, "the Recyclers".
Sincerely,
Anthony S. Georges.
Uhmmm...you do realize that silicon dioxide coating technologies like Plasmax are perhaps the most accepted barrier technology solution out there today amongst recyclers for PET as they have no demonstrable effects on the stream and no detrimental effects in separation efficiency and cost. Likewise, international organizations like PETCORE have done significant bottle to bottle recycling testing on Plasmax and other internal coating technologies for PET and have fully endorsed the technologies as having no effects on the PET recycle stream. Perhaps you should read up a little more on such things...
Dear Sir or Madame,
Last week's SSP trials at one of our clients demonstrated high amounts of silicone material being trapped in the screeen changers.
Where it came from raises additional questions and investigations will be on-going.
Regarding testing one material for a period of time has some results, but PET recyclers are operating on slim margins, where a variety of "Barrier" materials affect the quality of the PET.
There are too many types of barriers cooking in the market; with too many chefs claiming that their products do not affect the quality.
Too many chefs spoil the brooth!
Maybe you should check out some actual production sites!
Sincerely,
ASG.
Silicone is not the same as silicon dioxide and yes, have been to many recyclers in the US, Europe and Asia - I'm well versed in the myriad of recycling technologies being run in different parts of the world and have worked in the field...when one has a silicon dioxide coating approaching 50-75 nanometers thick on a container, the overall weight % doesn't even approach 100th's of a single percent and the coatings flake off during container grinding/wash and this has been bourne out in the market as there's virtually 0 remaining after elutriation. I agree that there are many different barrier technologies in the market, each with their own particular usefulness for a given application and potential issues downstream in recycling...however, my response is specific to your post on the announcement.
If you've got silicone trapped in screen changers, more than likely your issue is not with the bottle barrier technology (especially if Plasmax is SiOx, not silicone), but the closure that the package once had. There are alot of flip-top closures that utilize silicone dispensing valves - one can see these on many products, like ketchup, mustard, some sports drinks, etc. The unfortunate issue is that the silicone utilized has a density greater than 1.0 g/cc, so whereas the olefin closure will float in the wash/skimming tank in many recycling operations, the silicone will sink along with the PET during the operation...hence your issue most likely.....
Dear silicon dioxide,
I will have the client evaluate the stream of material coming in to the washing line to better evaluate your comments.
In our patented whole bottle washing technology, normally any loose caps and closures are removed along with almost all the labels and exterior, dirt, glass, sand, etc. so that only the bottles pass through to the optical sorting machines. These cleaned bottles allow the optical sorters to improve the selection process.
If these barrier bottles and/or silcone clousures bottles can not be detected, there is normally a manual sorter/checker to select out these type of bottles. I will see on the next visit what bottles are being selected out of the plant and try to update the discussion.
Have a good one, Anthony.
