46 Grease resistant coating as an alternative to fluoro-compounds
The proposed technology consists of a grease resistant food packaging coating for paper mills that is sustainable, natural and biodegradable. It represents a natural alternative to the use of non-biodegradable fluorocarbon coatings as a grease and oil barrier.

23 Making adhesives surfaces reversible
Thermo-expandable microspheres (TEMs), which consist of an outer shell of copolymer thermoplastic resin encapsulating a liquid hydrocarbon, when the heat trigger is applied at command the microspheres expand to over 100 times their volume, acting as a pressure activator to cleanly break the bond at the interface, and the cohesive structure. A key part of the patented technology is the functionalization of the TEMs surfaces, e.i. a conducting material is applied onto the polymeric shells of the microspheres. This additional layer enables quicker ways to get the heat to the TEM surface without damaging the material itself.
