Pulp and paper are manufactured from raw materials containing cellulose fi bers, generally wood, recycled paper, and agricultural residues. In developing countries, about 60% of cellulose fi bers originate from nonwood raw materials such as bagasse, cereal straw, bamboo, reeds, esparto grass, jute, fl ax, and sisal (Gullichsen 2000).
Making pulp from wood chips is the first stage in a standard paper production process. In North America, softwoods with thin, robust, and elastic fibers, including spruce and pine, are the most commonly utilized species. In general, there are two ways to make pulp, the primary component of paper: chemical pulping or mechanical pulping.

Readers of this article are urged to also study articles about energy audits at pulp and paper mills (Sweet 1991; Kong et al. 2016; Reese 2018; Reese and Deodar 2018; Gilbreath 2019; Reese et al. 2020). The largest and quickest savings in energy in pulp and paper mills usually are achieved as a result ...
You should spend about 20 minutes on this task. The diagram gives information about the process for making pulp and paper. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words. The diagram shows the process through which wood is used to manufacture pulp
Pulp and paper mills are categorized as a core sector industry and are the fifth largest contributor to industrial water pollution. Pulp and paper production has increased globally and will contribute to increase in the near future. For every tonne of paper produced, these mills generate 220-380 m3 of highly coloured and potentially toxic wastewater. The pulp and paper mill is a major ...
