This book features in-depth and thorough coverage of Minimum Impact Mill Technologies which can meet the environmental challenges of the pulp and paper industry and also discusses Mills and Fiberlines that encompass “State-of-the-Art” technology and management practices. The minimum impact mill does not mean "zero effluent", nor is it exclusive to one bleaching concept. It is a much bigger concept which means that significant progress must be made in the following areas: Water Management, Internal Chemical Management, Energy Management, Control and Discharge of Non-Process Elements and Removal of Hazardous Pollutants. At the moment, there is no bleached kraft pulp mill operating with zero effluent. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry. Sustainable pulp and paper manufacturing requires a holistic view of the manufacturing process. During the last decade, there have been revolutionary technical developments in pulping, bleaching and chemical recovery technology. These developments have made it possible to further reduce loads in effluents and airborne emissions. Thus, there has been a strong progress towards minimum impact mills in the pulp and paper industry. The minimum-impact mill is a holistic manufacturing concept that encompasses environmental management systems, compliance with environmental laws and regulations and manufacturing technologies.

“I glanced out the window as my train pulled into the station and saw the girl who killed my son.” So begins Josh Rolnick’s powerful debut collection of eight stories, which utilizes a richly focused narrative style accenting the unavoidable tragedies of life while revealing the grace and dignity with which people learn to deal with them. The stories—four set in New Jersey and four in New York—span the wide geographic tapestry of the area and demonstrate the interconnectedness of both the neighboring states and the residents who inhabit them. In “Funnyboy,” a grief-stricken Levi Stern struggles to come to terms with the banality of his son’s accidental death at the hands of Missy Jones, high school cheerleader. In “Pulp and Paper,” two neighbors, Gail Denny and Avery Mayberry, attempt to escape a toxic spill resulting from a train derailment when a moment of compassion alters both their futures forever. “Innkeeping” features a teenager’s simmering resentment toward the burgeoning relationship between his widowed mother and a long-term hotel guest. “The Herald” introduces us to Dale, a devoted reporter on a small-town newspaper, desperately striving to break a big-time story to salvage his career and his ego. A teenager deals with the inconceivable results of his innocent act before an ice hockey game in “Big Lake.” And in “The Carousel,” a Coney Island carousel operator confronts the fading memories of a world that once overflowed with grandeur and promise. Throughout, Rolnick’s characters search for a firm footing while wrestling with life’s hardships, finding hope and redemption in the simple yet uncommon willingness to act. Pulp and Paper captures lightning in a bottle, excavating the smallest steps people take to move beyond grief, heartbreak, and failure—conjuring the subtle, fragile moments when people are not yet whole, but no longer quite as broken.

This book presents an historical analysis of the global paper industry evolution from a comparative perspective. At the centre are 16 producing countries (Finland, Sweden, Norway, the USA, Germany, Canada, Japan, the UK, the Netherlands, Italy, Spain, Portugal, Chile, Brazil, Uruguay and Russia). A comparative study of the paper industry evolution can achieve the following important research objectives. First, we can identify the country specific historical features of paper industry evolution and compare them to the general business trends explicable by existing theoretical knowledge. Second, we can identify and isolate the factors causing both the rise and fall of industrial populations. Third, a shared research agenda can produce an intensive analysis of global industry dynamics. Finally, an extended research period of 250 years can identify what is truly unique in the paper industry evolution and the extent to which it took the same path as other important manufacturing industries.
