Researchers first had to address the very issue that makes superglue so “super” – it sticks to just about everything.

Our team used superglue as a starting material to develop a low-cost, recyclable and easily produced transparent plastic called polyethyl cyanoacrylate that has properties similar to those of plastics used for single-use products like cutlery, cups and packaging. Unlike most traditional plastics, this new plastic can be easily converted back to its starting materials, even when combined with unwashed municipal plastic waste.
To make a plastic from superglue, we first had to address the very issue that makes superglue so “super” – it sticks to just about everything. When superglue is used to stick something together, it is actually reacting with moisture in the air or on the surface of whatever is being glued together. This reaction forms molecular chains of repeating superglue units called polymers. The polymers made when gluing something together are short and don’t bind to each other well, which makes the glue brittle and easy to break.
While short polymers are good for glue, long polymers have more binding locations and result in stronger materials. Our team realized that if we could create longer versions of the same type of polymers made from superglue, we might be able to produce a strong plastic.
The way we make these plastics is relatively simple when compared with how other types of plastics are made – we simply mixed acetone and a little bit of an eco-friendly catalyst into store-bought superglue. Once this mixture dries, it produces a solid, glassy plastic made up of long polymer chains.
In our lab, we can easily produce up to 10 pounds of this material in a matter of days and turn it into usable products. By pouring the mixture into molds before it dries, we can make plastic objects in many shapes, like bowls and cutlery. We also discovered that heating up the plastic after it dries not only allowed us to shape the material into other products, but also strengthened the plastic.
The new superglue plastic is much easier to recycle than the kind of plastic used to make many single-use objects like cutlery. (Allison Christy / CC BY-ND) Why it matters When manufacturers need to produce a stiff plastic object – like cutlery, disposable razors, CD cases or plastic models – they often turn to polystyrene. Polystyrene is one of the most widely produced and least recycled types of plastic.
Because our superglue plastic has properties similar to polystyrene – it is light, durable, cheap and easy to mass-produce – it could replace polystyrene in many products. But there are two distinct benefits of our superglue-based material: It isn’t made from oil and is easy to recycle.
When our material is heated to 410 degrees Fahrenheit (210 C), the long molecule chains made of repeating superglue units break apart into their small, individual superglue molecules. At this point, the superglue molecules turn into a vapor that is easy to separate out from a mixed waste stream of other plastics, paper, food residue, aluminum and other refuse commonly found in recycling waste streams. Once you collect the superglue vapor, you can cool it and turn it right back into our new plastic with over 90% efficiency.
The superglue plastic can be shaped or molded into complex designs. (Allison Christy / CC BY-ND) What’s next? Since superglue is inexpensive and already produced on an industrial scale, we imagine our method of creating superglue plastics should be easy to scale up. Finally, the machinery used to make superglue could also be used to recycle the superglue plastics and could be simply adapted into existing industrial processes.
Finding a replacement for polystyrene is a big step toward sustainable plastics, but polystyrene is only one of thousands of plastics used today. Our team is now designing superglue-based plastics with properties that resemble other kinds of commodity plastics, while still being easy to produce and recycle.
Make a super glue plastic lawn chair as a gag/humor item. Your guest sits in it and cannot get out of it.
They can easily make ten pounds of it in just a few days. Oh, OK. So scalability is nearly impossible, but sure, let’s revolutionize plastics. Yep, I get it.
So...introducing a small bit of moisture to the two (or one) surface(s) to be super glued will improve the efficacy of the super glue?
Seems so...................
You can do many interesting things with super glue...

I must say, I was kind of blown away when I saw someone do that stuff with super glue and baking soda.
Of course, I am the kind of guy who goes to the State Fair, and sees the hawkers demonstrating their products like the slicer dicer devices, and I am in the crowd of people frantically pulling the money out of my pocket...:)

Brilliant plan! Guests that can’t leave. 🙄
“easily produced transparent plastic called polyethyl cyanoacrylate that has properties similar to those of plastics used for single-use products like cutlery, cups and packaging”
Yeah, I’m not using any compound with “cyano” in it for cutlery, cups, or food packaging.
If it is not made from oil, what is it made from?
Superglue component chemicals are derived from oil. Further, superglue exposure is known to cause lung and other problems in humans.
