Unlike most traditional plastics, this new plastic can be easily converted back to its starting materials, even when combined with unwashed municipal plastic waste.<\/p>\n\n\n\n<p>To make a plastic from superglue, we first had to address the very issue that makes superglue so \u201csuper\u201d \u2013 it sticks to just about everything. When superglue is used to stick something together, it is actually <a href=\"https:\/\/www.compoundchem.com\/2015\/10\/15\/superglue\/\">reacting with moisture in the air or on the surface<\/a> 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\u2019t bind to each other well, which makes the glue brittle and easy to break.<\/p>\n\n\n\n<p>While short polymers are good for glue, long polymers have more binding locations and <a href=\"https:\/\/www.science.org.au\/curious\/everything-else\/polymers\">result in stronger materials<\/a>. 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.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/images.theconversation.com\/files\/517014\/original\/file-20230322-22-qpq0uh.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img src=\"https:\/\/images.theconversation.com\/files\/517014\/original\/file-20230322-22-qpq0uh.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip\" alt=\"A stack of plastic petri dishes.\" \/><\/a><figcaption>The new plastic is made by elongating the molecular chains that make up superglue. Allison Christy, <a href=\"http:\/\/creativecommons.org\/licenses\/by-nd\/4.0\/\">CC BY-ND<\/a><\/figcaption><\/figure>\n\n\n\n<p>The way we make these plastics is relatively simple when compared with how <a href=\"https:\/\/www.bpf.co.uk\/plastipedia\/how-is-plastic-made.aspx\">other types of plastics are made<\/a> \u2013 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.<\/p>\n\n\n\n<p>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.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/images.theconversation.com\/files\/517012\/original\/file-20230322-18-txzoa3.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img src=\"https:\/\/images.theconversation.com\/files\/517012\/original\/file-20230322-18-txzoa3.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" alt=\"A clear spoon and knife.\" \/><\/a><figcaption>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, <a href=\"http:\/\/creativecommons.org\/licenses\/by-nd\/4.0\/\">CC BY-ND<\/a><\/figcaption><\/figure>\n\n\n\n<h2>Why it matters<\/h2>\n\n\n\n<p>When manufacturers need to produce a stiff plastic object \u2013 like cutlery, disposable razors, CD cases or plastic models \u2013 they often turn to polystyrene. Polystyrene is one of the most <a href=\"https:\/\/www.greenpeace.org\/usa\/news\/new-greenpeace-report-plastic-recycling-is-a-dead-end-street-year-after-year-plastic-recycling-declines-even-as-plastic-waste-increases\/\">widely produced and least recycled types of plastic<\/a>.<\/p>\n\n\n\n<p>Because our superglue plastic has properties similar to polystyrene \u2013 it is light, durable, cheap and easy to mass-produce \u2013 it could replace polystyrene in many products. But there are two distinct benefits of our superglue-based material: It isn\u2019t made from oil and is easy to recycle.<\/p>\n\n\n\n<p>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 <a href=\"https:\/\/www.europarl.europa.eu\/EPRS\/EPRS-Briefing-564398-Understanding-waste-streams-FINAL.pdf\">commonly found in recycling waste streams<\/a>. Once you collect the superglue vapor, you can cool it and turn it right back into our new plastic with over 90% efficiency.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/images.theconversation.com\/files\/517013\/original\/file-20230322-1056-ok9urc.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip\"><img src=\"https:\/\/images.theconversation.com\/files\/517013\/original\/file-20230322-1056-ok9urc.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip\" alt=\"A wavy bowl holding jelly beans.\" \/><\/a><figcaption>The superglue plastic can be shaped or molded into complex designs.

Finally, the machinery used to make superglue could also be used to recycle the superglue plastics and could be simply adapted into existing <a href=\"http:\/\/www.madehow.com\/Volume-1\/Super-Glue.html\">industrial processes<\/a>.<\/p>\n\n\n\n<p>Finding a <a href=\"https:\/\/lbl.recyclist.co\/guide\/6-plastic-polystyrene\/?embeddedguide=true\">replacement for polystyrene<\/a> is a big step toward sustainable plastics, but polystyrene is only one of <a href=\"https:\/\/www.plasticsmakeitpossible.com\/about-plastics\/types-of-plastics\/professor-plastics-how-many-types-of-plastics-are-there\/\">thousands of plastics used today<\/a>. 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.<\/p>\n\n\n\n<p><a href=\"https:\/\/theconversation.com\/profiles\/allison-christy-1425687\">Allison Christy<\/a>, Graduate Research Assistant, <em><a href=\"https:\/\/theconversation.com\/institutions\/boise-state-university-1983\">Boise State University<\/a><\/em> and <a href=\"https:\/\/theconversation.com\/profiles\/scott-phillips-1425731\">Scott Phillips<\/a>, Professor of Materials Science and Engineering, <em><a href=\"https:\/\/theconversation.com\/institutions\/boise-state-university-1983\">Boise State University<\/a><\/em><\/p>\n\n\n\n<p>This article is republished from <a href=\"https:\/\/theconversation.com\">The Conversation<\/a> under a Creative Commons license.
