Thanks for the input, Rob. Good to know that reverse logistics has been integrated into supply chain management, which makes sense. I haven't seen plastic return packages, either, so I don't think they're very common yet. Another reason this looked like a groundbreaker.

Yes, it probably is a groundbreaker, which fits with your coverage. Environmental advances seem to be all over the place these days. And more and more, the green avenue doesn't seem to be a cost-added road. That's good news.

I agree, one of the most exciting things about this development is not only saving cardboard (and trees, and carbon sequestration), but doing it with bioplastics, and then recycling them, too.

Thanks, Chuck. I was surprised to hear that ship-back cartons were still made of cardboard. Details about cardboard type weren't available, but I'd guess that it must have not been the corrugated variety.

Hi Ann,

Could you clarify your statement, "I haven't seen plastic return packages, either, so I don't think they're very common yet."?

The reason that I ask is that the company I work for designs and manufactures injection molded returnable systems.  But before I describe them in more detail, I wanted to make sure that it is those systems that you meant and not something else.

CLMDade, I meant ship-back or return containers, the subject of the article. Does that answer your question? And can you tell us more about what your company makes?

Ann,

I am the Senior Designer of Plastic Products for Schaefer Systems International.  One of our largest divisions is Returnable Packaging Solutions, which sells Close-Loop returnable solutions.  Mostly plastic, our products replace disposable, easily damaged products (i.e. wooden pallets, paper corrugated boxes).  These systems include plastic pallets and top caps with matching, multiple sized injection molded totes. 

A primary user of such systems in the U.S. is the automotive industry.  Their first tier suppliers are required to deliver their components to the assembly plants in approved packaging.  This usually consists of: a plastic tote, reusable dunnage (packaging within the tote, i.e. the cardboard partition set inside wine cases) and labeling with tracking and routing information. 

These filled totes actually travel to the workstations within the assembly plant.  The totes are emptied one part at a time as each component is installed in a car or sub-assembly.  The palletized empty totes are returned to the supplier to be restocked and reused.  This makes up a closed loop.

These packaging systems are bought en masse at the beginning of a car program and, barring forklift interactions, last the lifetime of the car model.  At the end of the program, all of the boxes/pallets/top caps can be ground up and recycled to make new product. 

As in your bio-plastic example, plastic returnable systems are usually more cost effective than disposable systems.  The upfront costs are higher, however, and saving money short-term sometimes gets in the way of real savings.

If you'd like more information, please ask.   I tried to keep this answer short. :)

CLMcDade, thanks for replying. I'd like to follow up this discussion with an off-list conversation, possibly leading to an article. Please contact me by email if you're interested.

Hi Ann,

I didn't see a way to email you other than choosing the "reply" button.  However,  this screen looks remarkably similar to the posting screen.  We'll see if this goes  to only you or if it ends up out on the message board.

I would be more than happy to speak with you.  After we establish that this is a method that goes directly to you, I can send my phone number.

Clinton

3D printing is now adding value to manufacturers at all steps along the business value chain. Come find out how at a talk by John Jaddou at next month's Embedded Systems Conference in Minneapolis.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
A team of researchers at Stanford University and IBM Research have developed a catalyst that could quickly and inexpensively generate biodegradable plastics derived from renewable materials.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
These new plastics are all aimed at cars, electronics and electrical components, plus medical devices, medical tool sterilization, and cleaning.
