Technology Prospecting on Enzymes for the Pulp and Paper Industry

17 Fungi and Their Enzymes for Pitch Control in the Pulp and Paper Industry

Technology Prospecting on Enzymes: Application, Marketing and Engineering

Enzymes are protein molecules functioning as specialized catalysts for chemical reactions. They have contributed greatly to the traditional and modern chemical industry by improving existing processes. In this article, we first give a survey of representative industrial applications of enzymes, focusing on the technical applications, feed industry, food processing and cosmetic products. The rec...

Roles for Microbial Enzymes in Pulp and Paper Processing

Microbial enzymes are enabling new technologies for processing pulps and fibers. Xylanases reduce the amount of chemicals required for bleaching; cellulases smooth fibers, enhance drainage, and promote ink removal; lipases reduce pitch; lignin-degrading enzymes remove lignin from pulps. Several of these processes are commercial, and others are beginning to emerge. In the future, enzyme-based pr...

Emissions Trading and Profitability: The Swedish Pulp and Paper Industry

The purpose of this paper is to develop models with and without potential emissions trading and to compare industry profits under the two regimes. The model in which emissions trading is permitted is a nonparametric industry frontier model in the spirit of Färe et al. (1992). It is relative to this model that industry profit is computed. This profit is compared to the profit without emissions t...

Environmental Noise Control in the Pulp and Paper Industry

The number of external noise sources of a paper making line is typically around 80 pcs. The major ones are process and machine room ventilation and vacuum pump exhausts. The noise control targets will dictate the scope and costs of sound attenuation. Considerable cost reductions can be achieved if the noise control design starts at the early stage of a project. Additionally, depending on the no...
