Book Description
Seminar paper from the year 2012 in the subject Environmental Sciences, grade: A, University of Nigeria (CENTER FOR ENVIRONMENTAL MANAGEMENT AND CONTROL), course: ENVIRONMENTAL MANAGEMENT AND CONTROL, language: English, abstract: The complexity of the paper issue means that firm conclusions are hard to draw. All paper manufactures causes harm to the environment and more often than not the determining factors in a paper mills. Environmental performance is not the process, paper type or fiber source but the location, mill practice and mill operator. Hence to try to grade paper products or production techniques into some kind of hierarchy of environmental performance, based solely on the manufacture process, is extremely difficult. Yet, globally however, the environmental impact of paper is significant, which has led to changes in industry and behavior at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, paper has become a cheap commodity everywhere. This has led to a high level of consumption and waste. With the rise in environmental awareness on the pollution of the Eco- system by the effluent of pulp and paper it became imperative to run a clearer analysis of its environmental impact.

Book Description
This report is a compilation of data for an assessment of environmental impacts of the US pulp and paper industry. That assessment will be part of a prototype study of the impacts of environmental legislation on industrial location patterns. The data reported here were gathered from published information and are estimates, by unit process, of emission coefficients for water and air emissions and solid waste. Processes considered are pulping, bleaching, papermaking, and energy conversion operations. Relevant environmental standards are presented, and control technologies required to meet new source performance standards are discussed. Cost estimates of the required control technology are reported on the basis of plant capacity.

Book Description
In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. We use patent data to examine the evolution of two completing bleaching technologies in five major paper-producing countries, both of which reduce the use of chlorine in the pulping process. By the end of the 1990s, nearly all pulp production in these countries used one of these technologies. Unlike other papers using patents to study environmentally-friendly innovation, we focus on a process innovation, rather than on end-of-the-pipe solutions to pollution. Moreover, while previous studies emphasize the importance of regulation for inducing innovation, here we find substantial innovation occurring before regulations were in place. Instead, pressure from consumers to reduce the chlorine content of paper drives the first round of innovation. However, while some companies choose to adopt these technologies in response to consumer pressure, not all firms will differentiate their product in this way. Thus, governments need to regulate if their goal is broad diffusion of the environmental technology.

Book Description
The pulp and paper industry produces large volumes of effluent containing, among other things, dark brown lignin and lignin degradation products. The exact nature of the chromophoric (colour causing) groups in the wastes and the effects of these colour bodies on the aquatic environment are not known. However, developmental work on several processes for colour reduction has reached full scale application and colour removal is now required in many local areas for various reasons. Colour reduction can be achieved by either technical changes within the mill or by effluent treatment systems. In-plant modification can range from simple, inexpensive measures such as pulp washing and better "housekeeping" practices, to complex technological changes such as implementation of oxygen bleaching. While in-plant changes should be considered and implemented as a first preference, external treatment may often still be required. There are a large number of external treatment methods which are known to be technically feasible for colour removal from pulp and paper mill effluents.

Book Description
Report analyzing the status of chemical pulp bleaching technology in Canada in 1993, including overall chemical and energy usage and related emissions; new and emerging technologies for the reduction or elimination of elemental chlorine and chlorine containing compounds in chemical pulp bleaching; the anticipated status of technology in 1997 and 2002 based on the expectation that the current best economically achievable technology will be in widespread use at that time; the anticipated state of technology in 2010 based on an extrapolation of current trends in emerging technology; and specific areas of research and development required to bring technologies to implementation. The report also outlines the current practices and trends for pulp bleaching in Europe and environmental regulations for absorbable organic halides (AOX) discharges in pulp mill effluent that may be implemented in Canada, the United States, and Europe over the next 10 years. Bleaching data, taken from file data, specific information received from individual mills, trade directories, and regulatory agencies, was compiled for the 43 bleached chemical pulp lines in operation at the end of 1993.
