Products have always been designed to fit battery design. Furthermore, when batteries run out, their disposal can pollute the environment. We’ve previously seen how paper batteries are being developed as a solution to these limitations. Now, Sweden-based BillerudKorsnäs has a plan to use its own paper battery design to create smart packaging. BillerudKorsnäs has developed the technology in collaboration with Uppsala University. The process uses algae to produce natural cellulose fibers. These are then manufactured into a conductive biopolymer that's also thin and flexible. BillerudKorsnäs has also been using the same materials in another project, to produce sustainable packaging. The…
