  • 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.

  • Resin Acids in Rosin (Colophony) Solder Flux Fume Laboratory Method Using Gas Chromatography
    Health and Safety Executive Resin acids in rosin (colophony) solder flux fume Laboratory method using gas chromatography Scope 1 This method describes the measurement of time-weighted average concentrations of rosin (also known as colophony) based solder flux fume collected onto membrane filters with analysis of the resin acid components, after derivatisation, by gas chromatography (GC). Summary 2 A measured volume of air is drawn through a membrane filter mounted in a sampling head close to the breathing zone. The filter is solvent desorbed, the resin acids derivatised and then quantified using GC with a flame ionisation detector (FID). If confirmation of the resin acid components’ identities is required, samples may also be analysed by GC with a mass spectrometer (MS) detector. However, MS is not recommended for quantitative analysis as, unlike an FID, the MS detector gives different response factors for the various resin acids. The use of alternative methods not included in the MDHS series is acceptable provided they can demonstrate the accuracy and reliability appropriate to the application. Recommended sampling 3 For long-term exposures: Maximum sampling time: 8 hours; Sampling rate: 1–2 l-1min; Sampled volume: up to 960 litres. For short-term exposures: Sampling time: 15 mins; Sampling rate: 2 lmin-1; Sampled volume: 30 litres. Prerequisites 4 Users of this method will need to be familiar with the content of MDHS14.1 Safety 5 Users of this method should be familiar with normal laboratory practice and MDHS83/3 carry out a suitable risk assessment. It is the user’s responsibility to establish appropriate health and safety practices and to ensure compliance with regulatory requirements.

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.

  • Resin Profile in a Bleached Kraft Pulp Process
    Resin Profile in a Bleached Kraft Pulp Process Jennie Berglund May 2012 Degree Project in Polymeric Materials, First Level Department of Fibre and Polymer Technology Royal Institute of Technology Stockholm, Sweden Abstract The aim with this project was to investigate how the amount and composition of resins varied during the process producing bleached birch pulp at the mill SCA Packaging Munksund. A literature study about how the resin removal can be improved has also been included. Problems with resins in the process are common at pulp and paper mills, especially when birch is used as a raw material. The resin can cause deposits on the equipment leading to process stops, but also lowered mechanical properties and spots on the paper products. The addition of tall oil to the digester is one way of improving the removal of resins, seasoning of wood, and a good debarking are other ones. Also the different washing and bleaching steps can affect the amount of resin remaining in the pulp. In this study pulp samples from eight different positions in the process were analyzed. To extract the samples a Soxtec device was used. Results showed that the most effective resin removal happened during the washing in their first washing step after the digester, a DD-washer. Here 77 % of the resin was removed, of totally 88 % during the whole process. Another step which was effective was the final washing step, the PO-press. About 36 % of the remaining resins in the pulp which entered the PO-press were washed out here. The extracts were analyzed with GC-FID and GC-MS to identify and quantify the substances, and determine how the composition varied over the manufacturing process.
