Benefits of Paper Recycling What Are the Most Significant Benefits of Paper Recycling? Recycling paper conserves natural resources, saves energy, reduces greenhouse gas emissions, and keeps landfill space free for other types of trash that can't be recycled. Recycling one ton of paper can save 17 trees, 7,000 gallons of water, 380 gallons of oil, 3.3 cubic yards of landfill space and 4,000 kilowatts of energy — enough to power the average U.S. home for six months — and reduce greenhouse gas emissions by one metric ton of carbon equivalent (MTCE). Who Invented Paper? A Chinese official named Ts'ai Lun was the first person to make what we would consider paper. In 105 AD, at Lei-Yang, China, Ts'ai Lun stirred together a combination of rags, used fishing nets, hemp and tree bark to make the first real paper the world had ever seen.3 Before Ts'ai Lun invented paper, people wrote on papyrus, a natural reed used by ancient Egyptians, Greeks, and Romans to create the paper-like material from which paper derives its name. Those first sheets of paper Ts'ai Lun made were pretty rough, but over the next few centuries, as papermaking spread throughout Europe, Asia, and the Middle East, the process improved and so did the quality of the paper produced. When Did Paper Recycling Begin? Papermaking and producing paper from recycled materials came to the United States simultaneously in 1690. William Rittenhouse learned to make paper in Germany and founded America's first paper mill on Monoshone Creek near Germantown, which is now Philadelphia. Rittenhouse made his paper from discarded rags and cotton. It wasn't until the 1800s that people in the United States started making paper from trees and wood fiber. On April 28, 1800, an English papermaker named Matthias Koops was granted the first patent for paper recycling — English patent no. 2392, titled Extracting Ink from Paper and Converting such Paper into Pulp. In his patent application, Koops described his process as, "An invention made by me of extracting printing and writing ink from printed and written paper, and converting the paper from which the ink is extracted into pulp, and making thereof paper fit for writing, printing, and other purposes." In 1801, Koops opened a mill in England that was the first in the world to produce paper from material other than cotton and linen rags — specifically from recycled paper. Two years later, the Koops mill declared bankruptcy and closed, but Koops' patented paper-recycling process was later used by paper mills all over the world. Municipal paper recycling started in Baltimore, Maryland, in 1874, as part of the nation's first curbside recycling program.7 And in 1896, the first recycling center opened in New York City.4 From those early efforts, paper recycling has continued to grow until, today, more paper is recycled (if measured by weight) than all of the glass, plastic, and aluminum combined. How Much Paper Is Recycled Every Year? In 2018, 68.2 percent of the paper used in the United States was recovered for recycling, for a total of 99 million tons. That's a 127 percent increase in the recovery rate since 1990, according to the U.S. Environmental Protection Agency. Approximately 80 percent of U.S. paper mills use some recovered paper fiber to produce new paper and paperboard products. .

Simultaneous Neutral Sulphite Semichemical Pulping of Hardwood and Softwood
Simultaneous Neutral Sulphite Semichemical Pulping of Hardwood and Softwood By Floris Antonides Submitted in fulfihnent of the academic requirements for the Degree of Master in Science in Engineering in the School of Chemical Engineering of the University of Natal December 2000 Abstract The work described in this thesis was aimed at obtaining a better understanding of the neutral sulphite semichemical pulping process employed by Mondi Kraft's Piet Retief mill, and to investigate ways to improve this process. The unique feature of the process in this mill is that hardwood and softwood species are pulped simultaneously in a continuous digester. The pulping trials described were carried out in a laboratory batch digester which was build as a part of this project. Pulps were evaluated for yield, Hypo number as an indication of the residual lignin content and strength properties. The first part of the experimental work focused on the effect that different pulping variables have on the process and the resulting pulp. Variables investigated were the chemical charge, pulping temperature, chip composition and anthraquinone dosage. The second part of the work was to investigate ways in which the process can be improved. In particular it was investigated whether it would be advantageous to pulp hardwood and softwood separately and mix the two pulps together after pulping. The effect of changing to_an alkaline sulphite process was also briefly investigated. It was found that the current process is optimized as far as the chemical charge and pulping temperature is concerned. Increasing the softwood percentage used to 50 % (from current value of 41 %) increases the tear strength, whilst decreasing it to 30 % increases the tensile strength of the resulting pulp.

Wildfires Are Usually the Product of Human Negligence
ACADEMIC READING PRACTICE TEST 5 – Wildfires & The History of Paper-making in the United Kingdom READING PASSAGE 1 Questions 1 – 13 You should spend about 20 minutes on Questions 1 – 13 which are based on Reading Passage 1 below. Questions 1 – 4 Reading Passage 1 has 5 paragraphs (A – E). From the list of headings below choose the most suitable headings for paragraphs B – E. Write the appropriate number (i – viii) in boxes 1 – 4 on your answer sheet. NB There are more headings than paragraphs, so you will not use them all. Example: Paragraph A Answer iii Wildfires A Wildfires are usually the product of human negligence. Humans start about 90% of wild fires and lightning causes the other 10%. Regular causes for wildfires include arson, camping fires, throwing away cigarettes, burning rubbish, and playing with fireworks or matches. Once begun, wildfires can spread at a rate of up to 23 kph and, as a fire spreads over a landscape, it could undertake a life of its own – doing different things to keep itself going, even creating other blazes by throwing cinders miles away. Three components are necessary to start a fire: oxygen, fuel and heat. These three make up “the fire triangle” and fire fighters frequently talk about this when they are attempting to put out blazes. The theory is that if the fire fighters can remove one of the triangle pillars, they can take control of and eventually put out the fire. B The speed at which wildfires spread depends on the fuel around them. Fuel is any living or dead material that will burn.

Handmade Paper: a Review of Its History, Craft, and Science
REVIEW ARTICLE bioresources.com HANDMADE PAPER: A REVIEW OF ITS HISTORY, CRAFT, AND SCIENCE Martin A. Hubbe a* and Cindy Bowden b For over 2000 years the manual craft of papermaking has been practiced all over the world utilizing a variety of techniques. This review describes the evolution of hand papermaking and its cultural significance. Paper’s evolution has been shaped by the structure and chemical composition of the fibers. Almost every aspect of modern papermaking technology has been foreshadowed by traditional practices. Such practices were passed down for many generations within families of papermakers. The main sources of cellulosic fiber evolved as the ancient craft migrated from its birthplace in China to Korea and Japan, the Islamic world, and then to Europe and America. Though most paper made today comes from automated, continuous production systems, handmade paper has enjoyed a resurgence, both as a traditional craft and as an art-form. In addition, traditional papermaking methods can provide insights to help in modern applications involving cellulosic fibers.

Each maker adopts or selectively omits parts of the methods that have been passed down to them, sometimes inventing new techniques.

Alan Crocker (1935-2018)
IN MEMORIAM ALAN CROCKER (1935-2018) Another of the remarkable group of people who founded BAPH has sadly left us. Alan Godfrey Crocker was born in Pontypridd, South Wales on 6 October 1935. Alan was edu- cated at Pontypridd Grammar School for Boys and went on to study mathematics at Imperial College, London, gaining his BSc (Special), ARCS in Mathematics, University of London, (Imperial College) in 1956 and his PhD on the ‘Theory of the Crystallography of Mechanical Twinning and Martensi- tic Transformations’, at the Department of Metallurgy, Uni- versity of Sheffield, in1959. From 1959 onwards his whole academic career was at the University of Surrey, originally the Battersea College of Technology, where he was Lectur- er 1959-1965, Reader 1965-1981, Professor 1981-2001 and Professor Emeritus 2001-2015. Over the years other posi- tions followed: in 1967 he became a Fellow of the Institute of Physics, a Fellow of Institute of Metals in 1978, a Chartered Engineer in 1978 and a Fellow of the Society of Antiquaries in 1989.

Including Binding, Paper and Papermaking, Printing, & Typog
Recent Studies on Books Printed 1660–1820 as Physical Objects: Including Binding, Paper and Papermaking, Printing, & Typography, 1985–2016 This bibliography surveys scholarship published from 1985 to 2016 concerning the physical features of printed materials produced c. 1660–1820. It is most inclusive for the years 1990–2014, in consequence of my compiling studies from those years for Section 1—"Printing and Bibliographical Studies"—of ECCB: Eighteenth-Century Current Bibliography. A 2015 revision corrected and added entries to the previous version of this bibibliography (2010), expanding the typescript from 74 to 112 pages. Then in early 2017, I expanded the list, particularly with studies of paper, to 154 pages. Included are studies of the physical features of particular books, editions and issues, such as bindings, paper, and type (as well as studies of the general period’s bindings, paper, type, typographical design, presses and presswork). Also included are studies of bookbinding, papermaking and typefounding as arts and studies of materials of production, as printing presses. I include some dissertations and many book reviews. In general, fields covered here are directly related to analytical and descriptive bibliography. For the English- speaking world, Philip Gaskell's A New Introduction to Bibliography (1972) remains the first step in such fields of study. Note that, although studies of bookbinding, papermaking and typography as industries or trades are included, studies of individuals in the bookbinding and type-founding trades have usually been placed in a bibliography on "Studies of Printers & Publishers and Publishing during the Long Eighteenth Century," which I posted in February 2017 at BIBSITE.

Lessons Learned from 150 Years of Pulping Woody
CHAPTER 3 Lessons Learned from 150 Years of Pulping Woody CARL HOUTMAN USDA, Forest Service, Forest Products Laboratory, One Gifford Pinchot Drive, Madison, WI 53726, USA Email: [email protected] 3.1 History The invention of the Gutenberg printing press in 1440 started a steady increase in demand for paper. Until the mid-1800s, most paper pulp was made by collecting, cleaning, and beating discarded linen and cotton rags. Collection of rags was such a large and organized industry that companies were regulated by the government and workers had unions. Henry Mayhew described a grand banquet of the fraternal order of chif- fonniers (rag-pickers).1 As literacy and printing technology improved, de- mand for paper outstripped supply, and the search for alternative sources of fiber began in earnest. For example, Jacob Christian Sha¨ffer, a noted clergyman and amateur botanist, in 1765 began releasing a six-volume treatise on new papermaking fibers.2 He explored the use of a wide range of natural materials to make paper and he bound samples of the paper in his books to demonstrate their quality. Ultimately Sha¨ffer started his own paper company. yThe U.S. Government is authorized to reproduce and distribute reprints for Government pur- poses notwithstanding any copyright notation hereon.
