Pulp and Paper by Josh Rolnick Pdf

“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.

Pulp and Paper Industry by Pratima Bajpai Pdf

Pulp and Paper Industry: Emerging Waste Water Treatment Technologies is the first book which comprehensively reviews this topic. Over the past decade, pulp and paper companies have continued to focus on minimizing fresh water use and effluent discharges as part of their move towards sustainable operating practices. Three stages—basic conservation, water reuse and water recycling—provide a systematic approach to water resource management. Implementing these stages requires increased financial investment and better utilization of water resources. The ultimate goal for pulp and paper companies is to have effluent-free factories with no negative environmental impact. The traditional water treatment technologies that are used in paper mills are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. This book discusses various measures being adopted by the pulp and paper industry to reduce water consumption and treatment techniques to treat wastewater to recover it for reuse.

The Complete Technology Book on Pulp & Paper Industries by NIIR Board of Consultants and Engineers Pdf

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.
