17、 fruits in the world. There are thousands of hectares of plantations in the world. The banana leaf is waterproof and has been used for serving food, packing food, takeaway for several decades in South India because it

19、h India), but the outer part is thrown away. Retting of the other part of the stem through chemical or mechanical methods can result in extraction of soft fibres of the banana plants that could be used as an alternativ
