Available in PDF, EPUB and Kindle. Book excerpt: Paper recycling in an increasingly environmentally conscious world is gaining importance. Increased recycling activities are being driven by robust overseas markets as well as domestic demand. Recycled fibers play a very important role today in the global paper industry as a substitute for virgin pulps. Paper recovery rates continue to increase year after year Recycling technologies have been improved in recent years by advances in pulping, flotation deinking and cleaning/screening, resulting in the quality of paper made from secondary fibres approaching that of virgin paper. The process is a lot more eco-friendly than the virgin-papermaking process, using less energy and natural resources, produce less solid waste and fewer atmospheric emissions, and helps to preserve natural resources and landfill space. Currently more than half of the paper is produced from recovered papers. Most of them are used to produce brown grades paper and board but for the last two decades, there is a substantial increase in the use of recovered papers to produce, through deinking, white grades such as newsprint, tissue, market pulp. By using recycled paper, companies can take a significant step toward reducing their overall environmental impacts. This study deals with the scientific and technical advances in recycling and deinking including new developments. - Covers in great depth all the aspects of recycling technologies - Covers the latest science and technology in recycling - Provides up-to-date, authoritative information and cites many mills experiences and pertinent research - Includes the use of biotech methods for deinking, refining. and improving drainage

Download or read book Investigation of Recycled Paper Deinking Mechanisms written by Veronika Husovska and published by . This book was released on 2013 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of water based inks is on the rise. Sub micron pigment particles are used for flexographic and inkjet water based inks. Conventional deinking eliminates larger particles than those from these new ink systems. Therefore, water-based inks represent recycling difficulty. Deinking experiments of water based inks are carried out. The deinking strategy initially investigated elimination of pressure sensitive adhesive due to similar acrylic polymer chemistry used in water based inks. The impact of pH on stickies and ink agglomeration during deinking is studied. Experiments in acidic regions show growth of acrylic inks and stickies agglomerates, simplifying elimination. Pre recycling of water based inks is explored. Exceptional cleanliness of acidic circuit waters compared to alkaline is demonstrated. Conventional wisdom claims an alkaline environment is needed for ink detachment from paper. It is found that the benefit of acidic milieu is the agglomeration of the pigment-resin complex of water based ink. Further, flotation deinking of model inks is performed. Agglomeration and flotation of inkjet inks using surfactants is performed to better understand ink behavior during deinking while limiting its redeposition. Three types of food grade soybean oils are tested for utilization in the paper recycling industry. Fatty acids extracted from oils are utilized in one loop flotation deinking of offset printed paper. Extracted fatty acids A, B and C had varied acid and saponification number. The effect of each of the soy-oil fatty acid on deinking is studied. Deinking results are compared to INGEDE 11p procedure, using oleic acid. It is discovered that fatty acids C and B have better deinking performance than oleic acid. Lower acid number acids perform better. Acid C and bentonite clay is used in one loop flotation deinking of inkjet printed paper. Fatty acid C is compared against oleic acid. It is determined that fatty acid C has positive effects on deinkability. The surface of the bentonite clay is altered by coating it with fatty acid C. Bentonite clay is successful in removing sub-micron hydrophilic inkjet ink pigment particles. Clay has a positive effect on the discoloration of recycled water.

This book was released on 2004-02-09 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pulp and paper industry continues to expand at a phenomenal rate and it has an important role to play on the Indian economy. This imposes a difficult problem of selection. Since the amount of material that can be included in a single volume is obviously limited. Careful thought has been given to the selection with the purpose of presenting that material which will be of the greatest interest to the greatest numbers. Paper is one of the major components of urban solid waste (household and commercial waste) and has a potential resource value when collected and reused. Recycling of the waste paper has been a practice that has prevailed in the paper industry since its inception and therefore continues. The preservation of forests and increasing environmental awareness has focussed research on exploration of new fibrous resources and less toxic pulping and bleaching processes. The use of non woody already account for 9.1% of total world papermaking capacity. A variety of non woody plant fibres are used for papermaking. Paper converting refers to the processing of raw paper to produce improved grade of paper or a finished paper article. There are two types of paper converting; wet converting and dry converting. The Indian paper industry has close linkages with economic growth as higher industrial output leads to increased demand for industrial paper for packaging, increased marketing spend benefits the newsprint and value added segments, and increased education and office activities increase demand for writing and printing paper. It is estimated that there is an economic growth of 8.5% for India which will benefit the demand for paper. This book basically comprises of bio refiner mechanical pulping of bast type fibres, use of trichromatic colourimetery for measurement of brightness and yellowness of bleached pulps, finishing and converting, coating equipment, chemical and additives in papermaking, mixed pulping of jute stick and other agricultural residues etc. This book also comprises of the list of manufacturers, suppliers of plant & machinery and allied products, list of manufacturers and suppliers of raw materials, imported pulp manufacturers & suppliers imported pulp, Indian agents for imported pulp etc. This informative book will be helpful for paper technologist, paper chemists and scientists related to paper field.
