Question

Plastic cups were used to serve tea in trains in early days- these could be
returned to the vendors, cleaned and reused. Later,Kulhads were used instead
of plastic cups. Now, paper cups are used for serving tea.
What are the reasons for the shift from Plastic to Kulhads and then finally to
