Reduction of waste and minimizing the cost of synthesis of products are the most important aspects of research and development in chemical and allied fields. Solid waste treatment is gaining importance due to its effect on the groundwater quality and soil quality. Solid waste can be dealt with by three principles, reduce, recycle and reuse. Reduction of solid waste by dewatering, reuse solid waste and recycling of non putrescible waste can reduce the solid waste treatment and disposal problem significantly. Many products like ethanol, acetic acid, microcrystalline cellulose, citric acid, pectic acids etc can be derived from waste materials. The use of agricultural materials for synthesizing various products is increasing. Microcrystalline cellulose (MCC) is one such product useful in bakery, dairy and beverage industry. It has also found applications in pharmaceutical industry. This product can be derived lignocellulosic biomass. Various treatment technologies can be use for pretreatment of biomass. Selection of raw material for MCC is based on factors such as raw material, composition, availability, toxicity, cost, byproduct generation, socioeconomic aspects. Acid hydrolysis is used for converting cellulose to MCC. This review aims to study various raw materials and methods for obtaining MCC from low cost feed stock.
