: Trees of specific age and size—often eucalyptus, birch, or poplar—are felled using forest harvesters.

: The final paper is wound into massive "jumbo reels" (up to 8.5 meters wide) before being cut into smaller, standard sizes for consumer use.

: Wood chips are boiled with water and chemicals in a "digester" to dissolve lignin , the natural glue that holds cellulose fibers together.

: The web passes through heavy rollers (nip rollers) that squeeze out up to 50% of the remaining water content.

The production of paper from wood is a complex industrial process involving several key stages: raw material preparation, pulping, sheet formation, and finishing. Modern mills can produce as many as 55,000 sheets per minute. 1. Raw Material Collection and Preparation

: The resulting pulp is cleaned to remove impurities. For white paper, the pulp is bleached using chlorine-free methods like oxygen or peroxide.

: Pulp is often mixed with recycled paper fibers and water to create a dilute suspension called "furnish" (approximately 1% fiber to 99% water). 3. Forming the Paper Sheet

: The pulp slurry is sprayed onto a moving wire mesh at high speeds (up to 90 km/h). Water drains through the mesh, leaving a mat of interwoven fibers known as a paper web .
