Fact Sheet: Paper and the Environment 1 FACT SHEET Paper and the Environment Paper and the Environment Fact sheet: paper and the environment 1 FACT SHEET Paper and the environment Paper and the environment For 2000 years, paper has helped shape the modern world. It has been hugely important in developing our cultural and creative life. Newspapers, magazines, books, packaging and banknotes are everywhere – and how many of us actually work in a ‘paperless office’? Concerns still abound over paper’s use and production. What paper you choose, and how you use it, makes a difference. This fact sheet concentrates on European paper production and use. Hopefully it will answer some of your main questions. Fact sheet: paper and the environment 3 Is paper bad for the environment? What to look for when choosing When recycled or FSC virgin fibre based paper are not available, then the fallback would be to ask for In a nutshell – no. Paper is made from a renewable a paper paper that is certified under an alternative forest raw material that can be recycled.

  • Elemental Chlorine-Free Bleaching of Soda Rapeseed Pulp
    ELEMENTAL CHLORINE-FREE BLEACHING OF SODA RAPESEED PULP FRANTIŠEK POTŮČEK and MARTINA ŘÍHOVÁ University of Pardubice, Faculty of Chemical Technology, Institute of Chemistry and Technology of Macromolecular Materials, 532 10 Pardubice, Czech Republic ✉Corresponding author: František Potůček, [email protected] Dedicated to the memory of the founder of the Cellulose Chemistry and Technology Journal, Acad. Professor Cristofor I. Simionescu Received November 18, 2016 Soda rapeseed pulps delignified to kappa numbers of 21.4 and 16.4 underwent elemental chlorine-free bleaching using chlorine dioxide, hydrogen peroxide, and peracetic acid as bleaching agents under laboratory conditions. Three four-stage bleaching sequences, DEPPPaa, D0EPD1P and D0EPD1D2, were applied to investigate the properties of bleached soda pulps, namely their brightness, zero-span breaking length and degree of polymerisation. For comparison, an oxygen-predelignified kraft softwood pulp with an initial kappa number of 10.5 was bleached under the same conditions. Soda pulps subjected to bleaching processes comprising two or three D stages were found to have a final brightness of 83.1 to 83.8% ISO, which was lower than that of 87.6 to 87.9% ISO obtained for kraft softwood pulp. The decrease in fibre strength was of only 7-9% for soda pulps, slightly greater than that of kraft softwood pulp. In contrast to fibre strength, the loss in the degree of polymerisation was considerable, roughly of 35% for soda pulps and 40 to 47% for kraft softwood pulp, depending on the

Pulping was carried out using rotary digester with 0.1% antraquinone, 20% active alkali (NaOH), cooking time of 120 min and temperature of 170 °C. ECF bleaching with chlorine dioxide – alkali extraction – chlorine dioxide – alkali extraction – peroxide sequence and beating in the range of 0 to 1000 revolutions were applied to the unbeaten and unbleached pulp. ECF bleached pulp produced soda-AQ durian rind paper with greater tensile index, burst index, tear index, number of folds, brightness and scattering coefficients, but with slightly lower opacity compared with paper made from unbleached pulp.

  • Tappi Peers 2020 Pulp Bleaching, Clo 2 Technology & Related Challenges
    18.3 Pulp Bleaching, ClO2 Technology & Related Challenges J. Barry Billett, Nouryon TAPPI PEERS November 3, 2020 Session18: Effective Bleaching Strategies eka.nouryon.com TAPPI PEERS November 3, 2020 Session18: Effective Bleaching Strategies Pulp Bleaching, ClO2 Technology and Related Challenges Preface In the highly competitive global Pulp and Paper industry the safe, reliable and efficient generation, storage and application of chlorine dioxide (ClO2) is one of several processes critical to sustainable management of bleached pulp production. Introduction Chlorine dioxide (ClO2) is a strong and selective gas phase oxidizer discovered in the early 1800’s and first used as a bleaching agent over a century later in the textile industry during the 1920’s. [26] Early applications for pulp bleaching dates back to the 1940’s. Due to ClO2’s oxidizing performance characteristics for producing brighter, stronger pulp, industry use continued to increase into the 1960’s and 70’s. [1-5, 10, 30-46] During the 1990’s local and federal environmental regulations further pushed the Canadian and US industries towards ECF pulp production, 100% ClO2 substitution. Over the past century driven by environmental, quality, cost and competitive considerations ClO2 has emerged as the globally dominant pulp bleaching agent. The benefits of ClO2 bleaching outweigh the associated challenges. [12, 30-46] However, to remain competitive the challenges associated with ClO2 demand significant industry investment and attention, particularly within aging North American (NA) facilities. In pulp mills ClO2 must be produced on site at the point of application which introduces a host of considerations. Safety is paramount within any modern industry and Under the US Code of Federal Regulations (29 CFR 1910.119), ClO2 is designated as a highly hazardous chemical, thus demanding site and organizational focus on Process Safety Management (PSM6) programs.

A glossary of commonly used terms is also provided in this section. 54 Australia & New Zealand Pulp & Paper Industry Guide 2015 Pulping & paper making technologies Details of the pulping technologies and steps in the paper-making process in Australia and New Zealand are presented in this section along with a glossary of terms commonly used in the industry. A basic illustration of a chemical pulp mill and integrated paper machine is shown in Figure 7. Figure 7 An illustration of an integrated chemical pulp mill and paper machine. Pulp mills can vary considerably, however the paper-making process is relatively constant across all grades of paper.

Cellulose fibres make up most of the woody mass of a Technology of tree. It is these fibres that are used in paper-making. In its simplest description, the fibres are ‘glued’ together by lignin, a complex organic polymer of varying composition, pulping and and this makes up wood (Fig. 8). Almost all the fibre used in both countries originates from paper making wood, either long-fibred softwood (generally pine) or short-fibred hardwood (generally eucalypt) trees.

Since the bleaching process is one of the most important environmental pollutant stages in the pulp and paper industry, here, the total chlorine-free (TCF) bleaching of poplar kraft pulp by applying Oxone and peroxide under alkaline conditions has been investigated. The pulp samples were bleached in two stages of OxoneX (O ) treatment using an AOX1OX2 sequence (A: acid pretreatment), and then the treated pulps were bleached by peroxide (P) to achieve target brightness (about 80%). The influence of various reaction parameters such as alkali charge, temperature, reaction time, and bleaching agent dosage was optimized. The final achieved brightness was more than 78%. Accelerated aging experiments showed more stability in brightness for the Oxone treated pulp, because alkali Oxone bleaching stops thermal degradation.

The yield after chemical treatment varied between 64.6 and 72.7% and the total yield after defiberizing was measured between 53.4% and 62%. The pulp produced applying 10% NaOH, 40 minutes pulping time and 95 °C pulping temperature was selected for bleaching trials. Elemental Chlorine Free (ECF) bleaching sequence was used for bleaching the selected pulp. Applying 3% (based on oven dry weight of the unbleached pulp) chlorine dioxide in D 0EPD1 bleaching sequence (2% in D 0 stage and 1% in D 1 stage) improved the brightness to 62.2% ISO. The kappa number of the ECF bleached pulp was reduced from the value of 40.1 to the final value of 13.4 for bleached pulp.
