Thanks for your feedback. I am sure that there would be other lessons, though I am less familiar with all the options available. I know another big challenge with packaging generally has been the use of composite materials, e.g. combinations of wood, plastic, cardboard and metal which are difficult to process for recycling.
Regarding connections - I am just about to leave the country for about a month and a half so I would only be able to do limited amounts remotely. However I have a number of passionate colleagues who I am sure would be happy to participate as well.
