ABSTRACT:
The vast amount of menstrual-related non-biodegradable waste produced in a nation like India, where women make up nearly 50% of the population, has serious environmental consequences. The bulk of the population in the country comes from low-middle class origins, therefore maintaining healthy menstrual hygiene practises with eco-friendly products calls for taking into account accessible and highly sustainable options. Furthermore, women are turning to the market for reusable products for inexpensive and durable alternatives because period poverty is now more prevalent than ever due to the COVID-19 pandemic. As a result, we investigated the Feasibility and Acceptability (FA) of a novel menstruation pad made of banana fibre in both rural and urban settings.

METHODOLOGY:
MATERIAL EXTRACTION:
Cottonfibreextraction:
We start by processing it through a machine that separates the thick fibre tufts from the ginned cotton bales (figure 2). The fibreisfedintoahopperthatmechanicallyseparatesthefibretufts,andtheseparatedfibreisthenfedintoaseriesof highly sophisticatedcleaningtechnologiesthatwecalledEVC(shorthandforEnhancedVisual,Opening,Cleaningsystem)(figure2). Thesetechnologiesremoveasignificantamountofplantmatter,suchasstalk,stem,andleaves,aswellasextraneousmatter andtrash.
The goal isto eliminateall non-lint material, but in practise,mechanical cleaning methodscan never completelyeradicate it. The remaining steps of the procedure take place in enormous containers known as kiers. To hasten the wet purification procedure,thesekettlescanbeheatedandpressured.Cottoniswetoutandpackedintolargecakeswithaholeinthemiddle (foraperfectvisual,imagineaBundtcake).Thecottoncakesarethenlowereddownintothekieranditisclosed(figure2).

Following that, a sodium hydroxide-containing solution is poured into the cotton scouring process during the processing of cotton (FIGURE 3). The alkali solution is continually pumped through the cakes as the kier is heated and pressured. The residualplantmatterissoftened,thewaxesonthefibrearesaponified(turnedintowatersolublesoaps),andthepectinsand othernon-cellulosiccomponentsaresuspendedsotheymaybewashedaway.

Thehydrogenperoxidewhitens thefibersbyoxidizingthecoloringmatter.Thepurifyingchemicalcanpermeatetheresidual plant matter more efficiently and make it white since the scouring process softens the remaining plant matter.In order to remove all colour bodies, the purifying solution is pushed through the cakes for a specific amount of time at a high temperature.Afterthat,thetankisdrainedandthepurifyingsolutioniswashedawaywithfreshwater.Atthisstageofcotton processing,allimpuritiesandcolouringagentshavebeeneliminated,leavingonlypurecelluloseinthecottonfibres.
StepFour:FiberFinishing
Despitetheremovalofthenaturalfibrefinish(wax),processingthefibremightbechallengingbecauseofthehighamountof fiber-on-fiber friction. Therefore, a fibre finish (lubricant) must be applied to enable efficient processing on high-production webformingmachinery.
Depending on the use required, a variety of fibre coatings can be used. The necessary level of finish can be imparted to the cottonfibresbypumpingthesefinishsolutionsthroughthecakes.Thecompletedsolutionisdrainedoncethetargetlevelhas beenreached.

BANANA FIBRE EXTRACTION:
Bananafibrescanberemovedfrombananasusingavarietyoftechniques,includingchemical,mechanical,andbiologicalones. Previous research has shown that biological approaches take at least a month before the fibres can be recovered while chemical procedures frequently harm the environment (FIGURE 5). However, the mechanical approach is simple and affordable,anditisverycommoninunderdevelopedcountries.

CONCLUSION
Bananafibreisoneofthemostenvironmentallyfriendlyrawmaterialsforsanitarypadsduetothemonocarpicreplantability ofbanana plantsandtheuseofagricultural wasteastheir pseudo-stem. Theyarebothenergy- efficientandsimpletomassproduce. The superior absorption qualities of banana fibre allowed us to create sanitary pads that are hygienic, simple to wash, and quick to dry. The prolonged life of these sanitary napkins can greatly reduce the environmental risk provided by discardedsanitarypads.
