  • Efficient steam production in paper mills

    The paper and pulp industry is an energy and emission intensive industry. Steam is an essential part of the paper making process with steam boilers, steam distribution systems and other processes accounting for a large percentage of a paper mill’s energy costs. Useful energy is often lost from boilers and process equipment such as heat exchangers, dryers, evaporators etc, as well as from ...

  • Vermicomposting of dewatered sludge from pulp and paper mill

    The present paper is aimed at conversion of dewatered sludge from pulp and paper mill into value added product through vermicomposting. The dewatered sludge was blended with cow dung and food processing waste in five different combinations R1 (1.5), R2 (1 + 0.24 + 0.26), R3 (1 + 0.34 + 0.16), R4 (1 + 0.41 + 0.09) and R5 (1 + 0.46 + 0.04) for utilisation in vermicomposting using Eisenia fetida. ...

  • The value of anaerobic purification for pulp and paper mill effluents

    In comparison to the food industry, anaerobic treatment had a later and a slower start in the pulp & paper industry. The first plants were installed in the beginning of the eighties and at the moment the number of projects that has been counted is approximately 140. Many of these plants have been installed as a pre-treatment stage before an activated sludge plant and reduce at least 80% ...

  • Pulp and paper mill aerated lagoon phosphorus optimization

    The Domtar (formerly Weyerhaeuser) Kamloops, BC bleached Kraft pulp mill discharges treated process wastewater to the Thompson River. The River and downstream Kamloops Lake have historically been identified as nutrient sensitive, with phosphorus contributing to algal growth. The BC Ministry of the Environment required that the mill perform a phosphorus optimization study to minimize phosphorus ...

  • Oil skimmer pays off for paper mill

    Skip Hogue is maintenance manager at St Joe Container Corporation, a paper mill and converter in College Park, GA that produces about 100 tons of corrugated boxes each day. Hogue noticed excessive oil in the wastewater discharge from boxboard operations. This oil comes from the rolls and bearings on the corrugating machines, and ends up in the plant's drainage system. Drainage water empties into ...

  • Paper Pulp by Enzymatic Treatment of Agricultural Residues and Waste Paper

    In the last years non woody plants, and particularly agricultural residues, received an increasing attention as source of fibres for paper mills. Their cell walls allow an efficient biopulping by means of enzymes. By adopting our LINA process, the enzymes are produced efficiently by solid-state fermentation (SSF) of lignocellulosic materials (Giovannozzi Sermanni and Porri, 1989). Therefore an ...


  • UNTHA optimises WtE production and metal recycling at Turkish paper mill

    An UNTHA shredder is now fully operational in Turkey’s first solid waste incineration plant. The single step XR3000C has transformed Modern Enerji’s approach to metal recycling, at the same time as boosting the production of ...

  • Potential utilisation of pulp and paper mill biosolids in composting and plant production: a case study at St. Marys Papers Ltd. (Canada)

    The use of St Marys Paper biosolids as a soil additive or growth cover was investigated. Biosolids were mixed with a commercial potting media in five vol/vol ratios and employed in a greenhouse study. The biosolids were found to improve Pinus banksiana seedling growth, a 50% biosolids:50% ProMix mixture yielding the tallest plants and highest dry mass. To further biologically stabilise the ...

  • Closing the Waste Loops: Australian Newsprint Mills

     The manufacture of newsprint is a process which generates both solid and liquid wastes. Australian Newsprint Mills Ltd Albury has given increasing attention to waste issues in recent years and has succeeded in closing or partially closing some of the ëwaste loopsí, especially in the areas of waste paper recycling, waste water, and solid waste. Background Australian ...


  • How to Turn Waste Paper into Biomass Pellets

    How to Turn Waste Paper into Biomass Pellets Along with the development of human civilization, the number of waste paper has a gradually increase trend every year. It is seen everywhere. Many ways have been researched to recycle the waste paper, while the waste paper has been polluted and there are many toxic substances contained, so it is not good for ...


  • Uniforet Mill, Quebec, Canada

  • Impact of using paper mill sludge for surface-mine reclamation on runoff water quality and plant growth

    Paper mills generate large amounts of solid waste consisting of fibrous cellulose, clay, and lime. Paper mill sludge (PMS) can improve reclamation of surface-coal mines where low pH and organic-carbon levels in the spoil cover material can inhibit revegetation. When applied at high rates, however, PMS may adversely impact the quality of surface runoff. Therefore, we applied PMS at 0, 224, and 672 ...

  • Pulp & Paper Mill’s #1 ASB Lagoon cleanout goes directly into Geotube containers - Case Study

  • Trials about composting of solid wastes from palm oil Mills in Indonesia

    The solid wastes produced in palm oil mills are empty fruit bunch (EFB), mesocarp fibre, shell, and palm kernel cake. On an average the amount of EFB is 0,220 t of 1 t oil palm fruit bunch (Singh, 1994). In Indonesia, there will be about 2.9 million tonnes EFB (dry basis) in 2000 (Lubis et. al. 1994). At the moment, EFB in Indonesian palm oil mills are burnt in incinerators to reduce the mass and ...
