This team was challenged with identifying biodegradable pressure sensitive adhesives for home-compostable price lookup (PLU) stickers. The team’s proposed alternatives include: proteins (gluten, Nb-1R, Arabinogalactan Proteins), polysaccharides (chitosan and carrageenan), biolipids (PHAs, Epoxidized Soybean Oil), and structural adhesives. The breadth of strategies explored provide excellent context, inspiration, and potential alternatives for the future of greener pressure sensitive adhesives.
