Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression.
Newsprint is a low-cost, non-archival paper consisting mainly of wood pulp and most commonly used to print newspapers and other publications and advertising material. Invented in 1844 by Charles Fenerty of Nova Scotia, Canada, it usually has an off white cast and distinctive feel. It is designed for use in printing presses that employ a long web of paper, rather than individual sheets of paper.
Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products.
The pulp and paper industry comprises companies that use wood, specifically pulpwood, as raw material and produce pulp, paper, paperboard, and other cellulose-based products.
Japan is the third country in the world in production of paper. The leading Japanese company in the field (2015) is Oji Paper, with three other Japanese companies – Sumitomo Forestry, Nippon Paper Group, and Unicharm – also in the world top 20.
The United States is one of the biggest paper consumers in the world. Between 1990 and 2002, paper consumption in the United States increased from 84.9 million tons to 97.3 million tons. In 2006, there were approximately 450 paper mills in the United States, accounting for $68 billion.
The pulp and paper industry in Europe accounts for about a quarter of world production and is a major employer. The leading producing countries are Finland, Sweden and Germany. The industry is a large user of renewable energy and achieved a recycling rate of 71.5% in 2015.
Kenaf [etymology: Persian], Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Hibiscus cannabinus is in the genus Hibiscus and is native to Africa, though its exact origin is unknown. The name also applies to the fibre obtained from this plant. Kenaf is one of the allied fibres of jute and shows similar characteristics.
A paper machine is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by filtering out the fibres held in a paper stock and producing a continuously moving wet mat of fibre. This is dried in the machine to produce a strong paper web.
The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibres, the main component of paper. The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na2S), known as white liquor, that breaks the bonds that link lignin, hemicellulose, and cellulose. The technology entails several steps, both mechanical and chemical. It is the dominant method for producing paper. In some situations, the process has been controversial because kraft plants can release odorous products and in some situations produce substantial liquid wastes.
Banana paper is a type of paper created from banana plant bark or banana peel fibers. Banana paper has a lower density, higher stiffness, higher disposability, higher renewability, and higher tensile strength compared to traditional paper. These qualities are due to the cellular composition of banana fiber, which consists of cellulose, hemicellulose, and lignin.
The recycling of paper is the process by which waste paper is turned into new paper products. It has a number of important benefits: It saves waste paper from occupying homes of people and producing methane as it breaks down. Because paper fibre contains carbon, recycling keeps the carbon locked up for longer and out of the atmosphere. Around two-thirds of all paper products in the US are now recovered and recycled, although it does not all become new paper. After repeated processing the fibres become too short for the production of new paper, which is why virgin fibre is frequently added to the pulp recipe.
Ballarpur Industries Limited (BILT) is a subsidiary of Avantha Group, and was once india's largest manufacturer of writing and printing paper. The current chairman of the company is Gautam Thapar, who succeeded his late uncle L.M. Thapar.
Malhar Sadashiv "Baburaoji" Parkhe, was an Indian industrialist. Parkhe was known to have a good study of Vedic literature. He was known to be a strong follower of Param Sadguru Shree Gajanan Maharaj of Shivpuri, Akkalkot and believer in his teachings of Agnihotra. He was involved in the worldwide propagation of the Agnihotra way of life. Parkhe delivered lectures and wrote several books on the subject.
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses, herbivore dung, or other vegetable sources in water. Once the water is drained through a fine mesh leaving the fibre evenly distributed on the surface, it can be pressed and dried.
Paper is a thin nonwoven material traditionally made from a combination of milled plant and textile fibres. The first paper-like plant-based writing sheet was papyrus in Egypt, but the first true papermaking process was documented in China during the Eastern Han period, traditionally attributed to the court official Cai Lun. This plant-puree conglomerate produced by pulp mills and paper mills was used for writing, drawing, and money. During the 8th century, Chinese paper making spread to the Islamic world, replacing papyrus. By the 11th century, papermaking was brought to Europe, where it replaced animal-skin-based parchment and wood panels. By the 13th century, papermaking was refined with paper mills using waterwheels in Spain. Later improvements to the papermaking process came in 19th century Europe with the invention of wood-based papers.
Liquid packaging board is a multi-ply paperboard with high stiffness, strong wet sizing and a high barrier coating, e.g. plastic. Only virgin paper fibers are used. The barrier coating must hold the liquid and prevent migration of air and flavors through the paperboard.
Nippon Paper Industries Co., Ltd. is a Japanese paper manufacturing company. The company's stock is listed on the Tokyo and Nagoya Stock Exchange and on the Osaka Securities Exchange. The stock is also constituent of the Nikkei 225 stock index.
Hemp paper is a paper variety consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers. Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. Because the paper industry's processes have been optimized for wood as the feedstock, production costs currently are much higher than for paper from wood.
