Major problem indeed. I absolutely agree that with increasing well known and easily accessible recycling locations, raising awareness (via online ads, apps etc.) and with planned education on the topic we can make a change! I've heard of the island. It horrifies me too.
Extremely good idea! Regarding the 3rd phase in particular that suggests a smart fridge opportunity that can seriously and easily be the not so distant future of refrigerators. Especially if the fridge just a few days before the expiry day sends you a little notification reminding you to consume the product. Maybe it can find connection with some cooking applications or online sites so within the notification it can suggest 5-6 healthy and easy to make recipes that include the product in question:) This way the user is encouraged to live it up in a friendly, helpful way. Once again, really good job, congratulations!
