Newcastle University engineers are at the forefront of adhesive technology that promises to change how we recycle. They have developed a reversible glue that sticks things together like any other glue but can debond on demand. The glue’s reversible nature means it can be used in a multitude of applications, from laminates to bottle labels. Dissimilar materials that are glued together can be easily separated, enabling their reuse, repurposing, or recycling.
