Introduction

Cellulose, a natural polymer composed of glucose monomers, is the main component of plant cell walls. It can be divided into three types: alpha cellulose, beta cellulose, and cellulose gamma, based on its solubility in alkali. Among the three types, alpha cellulose plays a crucial role in determining the quality of pulp and paper. In this analysis, we will discuss the importance of alpha cellulose, its role in pulp production, and the factors that influence its value.

Why is Alpha Cellulose Important?

Alpha cellulose, the purest cellulose fraction, is insoluble in 18% and 10% NaOH solution at 25 degrees Celsius. This means that alpha cellulose is not degraded by alkaline, making it an essential component of plant cellulose. In the context of chemical processed wood pulp, alpha cellulose value indicates the number of normal cellulose, while beta cellulose shows the size of the degraded alpha cellulose, and cellulose gamma shows the value of natural hemicellulose.

High alpha cellulose values indicate good pulp quality, providing higher strength, stiffness, and durability on paper. The higher the percentage of alpha cellulose, the stronger and durable the paper produced. Industrial standards stipulate that the alpha cellulose value is at least 94% for high-quality pulp.

High Quality Pulp Eucalyptus at PT Toba Pulp Lestari Tbk

PT Toba Pulp Lestari Tbk, one of the leading pulp and paper producers in Indonesia, uses Eucalyptus wood as the main raw material.
