Abstract

Microcrystalline cellulose is a valuable material with applications in pharmaceutical, medical and food industries. Its crystalline nature and physical properties make it a unique material used as an anti-caking agent, an emulsifier, an extender, a bulking agent texturizer and a fat substitute. Microcrystalline cellulose can be synthesized from various cellulose materials. In current investigation, rice husk and waste papers are used as feedstocks for synthesis of microcrystalline cellulose. Hydrolysis, pulping, bleaching and drying are steps in MCC synthesis with deinking as additional step for waste papers. The products were analysed by FTIR method and results were compared with reference for interpretation. Rice husk and waste papers were found to have excellent potential as microcrystalline cellulose feedstock.

2. Methodology

Raw Material Preparation

The rice husk from local rice mills was collected. The collected rice husk was washed with water to remove unwanted dust particles and impurities. The washed rice husk was then dried in hot air oven at 60-70°C for 1.5 hours and then sun dried. The resulting rice husk was then grinded into powder form with the help of kitchen grinder. Dried and grounded rice husk is shown in Figure 1. Waste papers required were collected from the waste of Gharda Institute of Technology. Waste and crushed papers are depicted in Figure 2.
