Paper is a thin material mainly used for writing upon, printing upon, drawing or for packaging. It is produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses, and drying them into flexible sheets.

Paper is a versatile material with many uses. Whilst the most common is for writing and printing upon, it is also widely used as a packaging material, in many cleaning products, in a number of industrial and construction processes, and even as a food ingredient – particularly in Asian cultures.

Papermaking is considered one of the Four Great Inventions of Ancient China, and the pulp papermaking process is ascribed to Cai Lun, a 2nd century AD Han court eunuch.[1] With paper an effective substitute for silk in many applications, China could export silk in greater quantity, contributing to a Golden Age.

Paper spread from China through the Islamic world to medieval Europe in the 13th century, where the first water-powered paper mills were built.[2] In the 19th century, industrial manufacture greatly lowered its cost, enabling mass exchange of information and contributing to significant cultural shifts. In 1844, Canadian inventor Charles Fenerty and German F.G. Keller independently developed processes for pulping wood fibers.[3] This
