The National Institute for Interdisciplinary Science and Technology (NIIST) here has developed the technology for extracting banana fibre from pseudo stems (leftover banana trunk) and empty bunches. Banana fibre is in demand to make textiles, yarn, paper, paper cups, cordage, tea bags, handbags and footwear.
New technique allows easier extraction of banana fibre
During the process, pectin, or the intercellular cementing substance present around the fibres, is degraded. This results in the separation of fibres from their embedding. "There is no pollution and the organic waste gets converted into biogas in the process. The process water is reused," Raj added.
Conventionally, the banana fibre is extracted through a cumbersome manual process, wherein the pseudo stem sheaths are scraped and the fibre is separated by using a metal scraper (flat and blunt blade). In this manner, just about 500 gm can be extracted. An alternate way is to extract the fibre through a mechanical process, which yields 10 times the quantity but with heavy damage to the fibre.
"The technology developed by CSIR-NIIST has the potential to generate employment and could offer higher earnings to farmers. The stems once cut are fit to be used in a week's time for the processing, after which they become redundant," Raj said.
