bamboo cup

I was tasked with creating a product that was completely sustainable and that had its whole life cycle considered.
I decided to make a coffee and drinking cup out of bamboo fibre and Cork that could be used to hold coffee
during the morning and then the lid can be changed to make it a normal drinking cup with a straw.
The body and Lid would be made of bamboo fibre and the middle would be made of cork
compression moulded unto the bamboo to prevent heat passing through.
