The last time I went, they were using paper boxes to pack their rice. The problem with this paper boxes is that they tend to turn soft and weak due to the sauce of the vegetable. Maybe someone here could suggest them to use plastic plates instead? This would be far more cost effective and environmental friendly.

It's reusable. And I'm sure they will treasure it as their "lunchbox". Plastic containers with caps would be good too. But cleanliness of reusing these material is rather hard to maintain.

Do you have any idea how recycable these papers are? And probably it's to save cost anyway. No easy task running a "free restaurant"
