Packaging, Pulp & Paper
How much water is used to produce a piece of paper? Even the crispest piece of A4 pulp paper has swallowed up to 20 litres of water during its production. The pulp and paper industry uses a huge amount of freshwater – in some nations an incredible 10% of all freshwater goes to make paper.
These two kinds of industries are normally separated. The pulp (raw material for paper industry) and the paper industry, produce different kind of waste water. There is also a third related industry, the paper recycling industry, which has a similar kind of waste water. In the following text the three branches of industry are separated.
The composition of pollutants in waste water of paper industries, depend on the kind of raw material which is used. For paper production wood, bagasse (outer stalk sugar cane), hemp, straw, etc. are used. Five basic procedures are used to produce pulp in an industrial way. The conduction of case can be with or without a bleaching process.
If a bleaching process is also step of production, the Lignin will be destroyed. The effect is a whiter paper. The color depends also on the different kinds of wood or other raw materials which are used for the production. This step have the disadvantage to load the environment more, because of the use of chemicals like chlorine or chlorine dioxide (which are restricted, because of the process).
