Subjective evaluation of bagasse composite handmade papers for variegated applications

Abstract

The handmade paper industry in India offers considerable potential to meet the increasing demand for paperproducts in an environmentally sound way. Though most paper made today comes from automated and continuousproduction systems, the handmade paper has enjoyed resurgence both as a traditional craft and as an art-form. In addition,traditional papermaking methods can provide insights to help in modern applications involving cellulosic fibers.Locallyavailable eco-friendly renewable resources viz., sugarcane bagasse, sisal fibre and maize husk, waste paper and cotton ragshave been used for development of handmade papers with different blend proportions (60:40 and 40:30:30) and GSM. Itwas found that, among the fibre blends bagasse: sisal: cotton pulp ( 40:30:30) was found to be more suitable for productionof handmade paper with optimum physical properties and further subjected to large scale production for validation andcost feasibility. Based on the sensory evaluation results, it was found that the blended handmade paper possessed acceptablerating for colour, texture, durability and thickness. Majority of the respondents stated that, the developed handmade paperwas more suitable for production of carry bags, paper plates, file covers and food wrappers. The production cost ofbagasse: sisal: cotton pulp (40:30:30) blended handmade paper was comparatively cheaper (Rs.136/kg pulp) than commercialcotton handmade papers (Rs.160/kg pulp). Hence, optimum utilization of underutilised natural fibres for handmade papermaking is an environment friendly process with an affordable cost and provides sustainable enterprise for rural artisans.
