The Miracle Resource Eco-Link
Since 1989 Eco-Link Linking Social, Economic, and Ecological Issues The Miracle Resource Volume 14, Number 1 In the children’s book “The Giving Tree” by Shel Silverstein the main character is shown to beneÞ t in several ways from the generosity of one tree. The tree is a source of recreation, commodities, and solace. In this parable of giving, one is impressed by the wealth that a simple tree has to offer people: shade, food, lumber, comfort. And if we look beyond the wealth of a single tree to the benefits that we derive from entire forests one cannot help but be impressed by the bounty unmatched by any other natural resource in the world. That’s why trees are called the miracle resource. The forest is a factory where trees manufacture wood using energy from the sun, water and nutrients from the soil, and carbon dioxide from the atmosphere. In healthy growing forests, trees produce pure oxygen for us to breathe. Forests also provide clean air and water, wildlife habitat, and recreation opportunities to renew our spirits. Forests, trees, and wood have always been essential to civilization. In ancient Mesopotamia (now Iraq), the value of wood was equal to that of precious gems, stones, and metals. In Mycenaean Greece, wood was used to feed the great bronze furnaces that forged Greek culture. Rome’s monetary system was based on silver which required huge quantities of wood to convert ore into metal. For thousands of years, wood has been used for weapons and ships of war. Nations rose and fell based on their use and misuse of the forest resource. -

Basics of Kraft Pulping
Lignin Wood is composed of many chemical components, primarily extractives, carbohydrates, and lignin, which are distributed nonuniformly as the result of anatomical structure. Lignin is derived from the Latin term lignum, which means wood.1 Anselme Payen (1838) was the first to recognize the composite nature of wood and referred to a carbon- rich substance as the “encrusting material” which embedded cellulose in the wood. Schulze (1865) later defined this encrusting material as lignin. Lignin has been described as a random, three-dimensional network polymer comprised of variously linked phenylpropane units.2 Lignin is the second most abundant biological material on the planet, exceeded only by cellulose and hemicellulose, and comprises 15-25% of the dry weight of woody plants. This macromolecule plays a vital role in providing mechanical support to bind plant fibers together. Lignin also decreases the permeation of water through the cell walls of the xylem, thereby playing an intricate role in the transport of water and nutrients. Finally, lignin plays an important function in a plant’s natural defense against degradation by impeding penetration of destructive enzymes through the cell wall. Although lignin is necessary to trees, it is undesirable in most chemical papermaking fibers and is removed by pulping and bleaching processes. 1.1.1 Biosynthesis Plant lignins can be broadly divided into three classes: softwood (gymnosperm), hardwood (angiosperm) and grass or annual plant (graminaceous) lignin.3 Three different phenylpropane units, or monolignols, are responsible for lignin biosynthesis.4 Guaiacyl lignin is composed principally of coniferyl alcohol units, while guaiacyl-syringyl lignin contains monomeric units from coniferyl and sinapyl alcohol. -

THE USE OF OLD CORRUGATED BOARD IN THE MANUFACTURE OF HIGH QUALITY WHITE PAPERS by Rene' H. Kapik A Thesis submitted in partial fulfillment of the course requirements for The Bachelor of Science Degree Western Michigan University Kalamazoo, Michigan December, 1983 ABSTRACT Clean corrugated board waste was fractionated into its softwood/ hardwood fiber components, repulped using a kraft pulping process, and bleached using a CEHD bleaching sequence in an effort to produce high brightness fiber suitable for use in medium to high quality white paper. The papers produced had almost equivalent mechanical strengths and opacity, but possessed unsatisfactory brightness and cleanliness when compared to commercially manufactured,:. bleached kraft pulps of identical softwood/hardwood contents. Based on this experimental data, the use of recycled fiber from corrugated board as a fiber substitute in the manufacture of high quality printing and writing papers is not recommended due to its inferior brightness and cleanliness. -

Based on published data, the WestVaco process, the LignoBoost process, the LigoForce SystemTM and the SLRP process are reviewed and discussed for the isolation of lignin from Kraft black liquor. The three new processes that have now joined the WestVaco process are compared from the perspective of product quality. Further, isolation processes of lignosulfonates from spent sulfite liquor are reviewed. The limitation for this review is that data are only available from lab scale and pilot scale experiments and not from industrial processes. Key output of this paper is a technology summary of the state of the art processes for technical lignins, showing the pros and cons of each process.

polymers Review A Review of Wood Biomass-Based Fatty Acids and Rosin Acids Use in Polymeric Materials Laima Vevere *, Anda Fridrihsone , Mikelis Kirpluks and Ugis Cabulis Polymer Department, Latvian State Institute of Wood Chemistry, 27 Dzerbenes Str., LV-1006 Riga, Latvia; [email protected] (A.F.); [email protected] (M.K.); [email protected] (U.C.) * Correspondence: [email protected]; Tel.: +371-28869638 Received: 26 October 2020; Accepted: 14 November 2020; Published: 16 November 2020 Abstract: In recent decades, vegetable oils as a potential replacement for petrochemical materials have been extensively studied. Tall oil (crude tall oil, distilled tall oil, tall oil fatty acids, and rosin acids) is a good source to be turned into polymeric materials. Unlike vegetable oils, tall oil is considered as lignocellulosic plant biomass waste and is considered to be the second-generation raw material, thus it is not competing with the food and feed chain. The main purpose of this review article is to identify in what kind of polymeric materials wood biomass-based fatty acids and rosin acids have been applied and their impact on the properties. Keywords: crude tall oil; tall oil; fatty acids; rosin acids; polymer materials 1. Introduction The success of plastics as a commodity has been significant and polymer materials are a part of everyday life. The advantages of polymers over other materials can be attributed to their adjustable properties, low cost and ease of processing. Worldwide, the manufacturing of polymers grows every year, reaching almost 360 million tonnes in 2018 [1]. In the light of environmental challenges of the 21st century, the development of novel low-cost and scalable monomers from renewable resources is essential. -
Tall Oil Production and Processing
TALL OIL PRODUCTION AND PROCESSING Tall oil is a mixture of mainly acidic compounds found, like turpentine, in pine trees and obtained as a by-product of the pulp and paper industry. It is used as a resin in many different industries, including mining, paper manufacture, paint manufacture and synthetic rubber manufacture. It is extracted at the pulp and paper mill, and undergoes the first two processing steps there. Step 1 - Extraction of tall oil soap The "black liquor" from the paper making process is concentrated and left to settle. The top layer is known as "tall oil soap", and is skimmed off. The rest is recycled for further use in paper making. Step2 - Production of crude tall oil The tall oil soap is reacted with acid to form crude tall oil. The following reaction occurs: + + R—COONa + H3O → R—COOH + H2O + Na The acids formed from this reaction, along with small quantities of other compounds of similar volatility, make up the crude tall oil. All crude tall oil produced in New Zealand is then sent to a plant in Mt. Maunganui to complete processing. Step 3 - Crude tall oil distillation The oil is distilled into five components with different boiling points: heads (which boils first), then fatty acids, distilled tall oil (a mixture of fatty and resin acids), resin acids (collectively known as rosin) and pitch (the residue). All of these can be used in various industries as is, but some of the rosin is also further processed on site. Step 4 - Production of rosin paper size "Paper size" is the substance that stops all paper from behaving like blotting paper. -
