This four volume set covers the entire spectrum of pulp and paper chemistry and technology from starting material to processes and products including market demands. This work is essential for all students of wood science and a useful reference for those working in the pulp and paper industry or on the chemistry of renewable resources.
Volume 1 provides a survey of the biological and chemical structure of wood as well as an introduction to the chemical reactions used during pulp production processes. The work presents
the different raw materials used for pulp production, the macroscopic and morphological construction of wood and related characterization methods, the chemical structure and arrangement of the wood polymers and extractives, biosynthesis of wood polymers, carbohydrate and lignin analysis, reactions of wood polymers in mechanical and chemical pulping and bleaching processes, biotechnical processes of relevance for the pulp and paper industry, different types of microorganisms and their modes of interaction with wood, the impact of chemical and microbiological processes on the hierarchical structure of wood and pulp.

Volume 2 focuses on creating an understanding of the chemical and technical processes involved in the production of pulp. The work treats
wood handling, i.e. barking, chipping , storage and screening processes, chemistry and technology during mechanical and chemical pulp production, including pulping and bleaching chemistry and technology, production of bleaching chemicals at the mill, recovery processes, including the treatment and burning of black liquor and the white liquor preparation plant, paper recycling processes, changes in structure and properties of wood polymers and pulps in the pulping process line, description of the equipment and processes involved in the manufacturing of pulp, pulp characterization, including methods available to evaluate pulp properties, end-product requirements.

Volume 3 provides an overview of paper production and the ways in which the chemistry of starting materials and processes influence its quality and properties. The work treats
fundamental properties of the fibre wall and the consolidation of fibres during pressing and drying, surface chemistry of fibres and their influence on the interaction between fibres/paper and other materials, mechanisms behind the adsorption of polyelectrolytes to fibres and fillers, acid and alkaline sizing of paper, basic fluid mechanical behavior of fibre suspensions, web forming, web pressing and web drying in a modern paper machine, calandering and coating of paper.

This volume examines the physical properties of paper and modern demands on this versatile material. The book presents
fundamental definitions of fibre networks and their structure, physical properties of the paper and their development during pressing and drying, interactions with moisture and its affect on mechanical properties, interactions between light and fibrous materials and the determination of optical properties of the paper, physical action of dry-strength and wet-strength chemicals, physical properties of the paper surface with special emphasis on printing and print quality, overview of packaging materials and the demands on paper from a packaging materials perspective, laminate theories for papermakers and theoretical models of paper for converting and end-uses.

Jag har alltid älskat livet. En gång var jag som vilket annat barn som helst: nyfiket och tillitsfullt. Men de som stod mig närmast svek. Min uppväxt kantades av övergrepp som fick mig att tro att jag var värdelös. Som vuxen levde jag med män som misshandlade mig svårt och jag drabbades av cancer tre gånger.
Mitt liv har varit en resa genom mörker och ljus. Jag har varit i det svartaste helvete men också mött människors bästa, vackraste sidor. Aldrig har jag givit upp. Nu vill jag dela med mig av min berättelse för att stärka andra. Det finns hopp. Det finns ljus. Ge aldrig upp!

Till mina läsare
Mitt hopp är att du som läser detta ska förstå att man kan klara av alla helveten i livet och gå vidare. Inget är lätt, det kan kräva år av bearbetning. Men om du nu går igenom mörker och svårigheter, eller lider av händelser du tidigare varit utsatt för, vill jag ge just dig hopp och en strimma ljus i mörkret. Ge aldrig någonsin upp!
Det jag har lärt mig under åren är att det största och viktigaste i livet är att kunna förlåta. Den dagen du kan förlåta det svåra du varit utsatt för kan din väg mot frihet och inre frid börja. Det går att nå försoning.
Störst av allt är kärleken.

I have always loved life. Once I was like any other child: curious and trustful. But those who were closest to me betrayed me. I grew up surrounded by abuse that made me believe I was worthless. As an adult, I lived with men who abused me badly and I suffered from cancer three times.
My life has been a journey through darkness and light. I have been in the darkest hell but also met the best, most beautiful sides of people. I have never given up. Now I want to share my story to empower others. There is hope. There is light.
Never give up!
