Last week Kristin Syverud from RISE PFI held a presentation on a meeting arranged by the Vinnova competence centre FiBre at KTH in Stockholm. The presentation was based on the work described in the recent reviews \u201cHydrophobization of lignocellulosic materials part I: physical modification, Hydrophobization of lignocellulosic materials part II: chemical modification and Hydrophobization of lignocellulosic materials part III: modification with polymers\u201d published in Cellulose<\/em>.<\/span><\/p>\n

Sandra Rodriguez Fabia at RISE PFI is the first author of these reviews.<\/span><\/p>\n

The excessive use of fossil fuel-based products in today\u2019s society is one of the main sources of CO2<\/sub> emissions.<\/p>\n

In recent years some measures have been taken to reduce plastic use. A very good example is the EU directive (EU) 2019\/904 against single-use plastics. As a result, many plastic products, such as cutlery, cups and plates, have been replaced by cellulose-based materials. However, cellulose is a material that has affinity for water, and it needs to be become water-resistant (at least for a limited period of time) if it has to be in contact with food. To achieve that, cellulose should be modified by different methods to make it waterproof enough so that a paper cup can contain liquids without disintegrating.<\/p>[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.20.0″ _module_preset=”default” custom_padding=”46px|38px|33px|38px|false|false” border_color_all=”#464b11″ global_colors_info=”{}”][et_pb_image src=”https:\/\/rise-pfi.no\/wp-content\/uploads\/2023\/03\/chemical-modification_1000_web.jpg” title_text=”Hydrophobization of lignocellulosic materials” _builder_version=”4.20.2″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” alt=”Hydrophobization of lignocellulosic materials” sticky_enabled=”0″][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”]

The three reviews mentioned above summarize the available technologies to obtain hydrophobic cellulose-based materials. These methods range from \u201csimple\u201d coating technologies to complex chemical modifications. Hydrophobization of cellulosic materials is a topic that will become more and more relevant in the future as plastics are replaced by other materials. <\/span><\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_4,1_4″ _builder_version=”4.20.2″ _module_preset=”default” custom_padding=”3px|||||” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.20.2″ _module_preset=”default” custom_padding=”45px||||false|false” global_colors_info=”{}”]
