How to make organic utensils. Industry in Tripura. ITI DHARMANAGAR. UTENSILS USING LEAF

i have visited an Indian industry where people are making plate, pot, spoon, glass, dish etc by using betel nut leaf. This is a recycled waste material product and also we can say them ORGANIC UTENSILS.
these use and through utensils are enviornment friendly, no chemical used to make them and when you through them after use, they will easily dissolve in soil within few days. As they are actually made up from dried leaves, they will never harm our nature.
This Indian industry is very popular and also they are selling millions of plates in a month. This is also deliverable in abroad.
