Looking at the impact of plastic waste, this is indeed a great idea..I'm hoping it'll be widely available and economic, so consumers/suppliers will take this as a viable option and use it instead of plastic.

Also, I realize although cassava are ubiquitous in South East Asia, it isn't so common in western countries..Is there any similar solution with any other material?

Hi Kerrin McLaughlin ,
As a busy young professional/student living in a shared house, I definitely need and will use this.
What happens a lot is that, I bought loads of groceries, and it gets difficult to keep track what I have and also their expiry dates.

Feel free to interview me (if you need to) or please let me know once this idea comes to life!

That's really well thought! I like the "under-loved ingredients" better than "would-be-waste".
Also bear in mind, picking the right target goes a long way!
