The presentation introduced several technology systems implemented at a South Carolina mill to improve safety, environmental, and quality management. These included a safety management system, MSDS system, emergency response system, process safety management system, environmental management system, ISO quality management system, and department training and document control systems. The systems provide standardized policies and procedures, training records, and document control across the mill.

The document discusses the marketing mix concept and its 4 P's (product, price, place, promotion). It explains that the marketing mix must reflect the wants and desires of the target consumers in order to be successful. Marketers use both formal and informal research to understand what consumers want and are willing to pay for in order to gain a competitive advantage. The effective application of the marketing mix is marketing management.
Some thoughts on yankee paper machine felt lifeDevesh Singhal
The document discusses factors that affect the life of felts used on yankee paper machines. It notes that felt life is difficult to predict precisely due to various machine parameters. Three main factors that can improve felt life are identified: 1) improving fiber positioning and distribution to reduce fines in the top paper layer, 2) optimizing nip loading between the yankee cylinder and touch roll to reduce felt compaction, and 3) effective felt conditioning systems to remove trapped fines from the felt. The buildup of fines in felts over time can significantly reduce their porosity and lifespan.
This document summarizes FAG Industrial Services' experience providing online condition monitoring systems for the pulp and paper industry. It describes systems for monitoring dryer sections, press sections, yankee cylinders, and other equipment. Case studies show the systems can detect bearing defects early, avoiding unplanned shutdowns and costly repairs. Customers benefit from reduced downtime and maintenance costs through FAG's remote monitoring services and expert analysis of vibration data.
Wrinkles & Piping in paper reels is an annoying problem. When the reel is used for any conversion, printing, lamination or anything, you get rejects and rejects. This presentation gives some thoughts on how can we minimize wrinkles and piping.
This document provides an overview of bleaching chemical pulps. It defines bleaching as the chemical treatment of pulp to increase brightness, cleanliness, and brightness stability while preserving fiber strength. Bleaching removes residual lignin using oxidizing agents like chlorine, chlorine dioxide, and oxygen. Compared to pulping, bleaching is more selective and removes less lignin but produces problematic effluents. The document discusses important pulp properties affected by bleaching like brightness, viscosity, and fiber strength. It also covers bleaching chemicals, how their oxidizing power and efficiency can be measured, and their environmental impacts.
Chemical modifications of natural fibres for composite applicationsketki chavan
This seminar report discusses chemical modifications of natural fibres for composite applications. It introduces composites and their constituents such as reinforcement, matrix and interface. It then classifies fibre reinforced composites and discusses market trends for natural fibre reinforced composites in automotive and construction industries. The report examines advantages and disadvantages of natural plant fibres such as flax, hemp and jute compared to conventional fibres. It describes the structure of plant fibres and various physical, biological, nanotechnology and chemical modification techniques to improve mechanical properties and interface bonding of natural fibres in composites. Specific chemical treatments including alkali, silane, acetylation and permanganate treatments are explained along with reaction mechanisms. Case studies on jute

The document provides an overview of tissue machine operator training, focusing on crepe tissue production and the factors that influence creping. It discusses how increasing percent crepe through differences in yankee and reel speeds can improve sheet properties like bulk and softness. It also explains that coatings are applied to the yankee dryer to hold the sheet during creping and help build a good roll, while release aids facilitate sheet removal and influence properties. Common problems and methods for adjusting crepe, coatings and release aids to protect the dryer surface and meet sheet specifications are described.

Traduzione del rapporto INPO commissionato dalla NEI e pubblicato novemre 2011 sulla sequenza dell'incidente alla centrale nucleare Daiichi a Fukushima
The document provides an additional report from the Japanese government to the IAEA on the Fukushima Daiichi nuclear accident. It summarizes further developments in understanding the earthquake and tsunami, the status of the accident response, and ongoing efforts to address lessons learned. It describes efforts to stabilize cooling of reactors and spent fuel pools, and examines response plans for decontamination and long-term management of the site. The report aims to provide transparency and engage international cooperation as Japan works to restore stability and prevent future nuclear accidents.

Alcuni scenari di studio per comprendere i possibili impatti ambientali, occupazionali e di sicurezza energetica derivanti dalla costruzione e dalla conseguente messa in esercizio di nuove centrali nucleari nel nostro paese, come previsto dal Governo attraverso la “Legge Sviluppo” del 2009.

The document discusses how the global financial crisis is impacting energy investment and climate change efforts. It notes that investment in renewable energy declined in the last quarter of 2008 due to higher financing costs and lower oil and gas prices. Across the energy industry, consolidation is expected as large companies acquire assets from struggling smaller producers. The crisis also threatens progress on reducing emissions as investment in low-carbon technologies declines without government intervention.
