<p>According to the invention, the cellulose pulps for paper industry are made from stems of a plant of specie Sida hermaphrodita Rusby that is free from resins and fatty acids. This kind of raw material is very easy to obtain and is characterised by ten times higher productivity from an area unit in comparison to traditional materials such as wood. These processes do not require operations connected with neutralisation of resins and fatty acids typically found in waste water resulting from traditional processes.</p> |
