The aim of CLS Sodalitas is the development, production and sale of cellulose nanoparticles (CNs), made from agricultural biomass, rubble and cellulose-based waste and by-products of the paper, textiles and agri-food industries.<\/p>\n

[\/vc_column_text][vc_empty_space height=”50px”]

Sodalitas uses two different techniques for the production of cellulose nanoparticles (CNs)<\/div>[vc_row_inner row_type=”row” type=”grid” text_align=”center” css_animation=”” padding_top=”25″][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

one which associates preparation, transformation, purification and functionalisation steps to a mechanical process, to achieve the extraction of cellulose nanofibrils (CNFs)<\/p>\n

Micro-Nanofibre Cellulosiche<\/p>\n

<\/div>\n<\/div>\n<\/div>
CNFs will be typically put to use in the production of paper<\/strong>, paying particular attention to special products and innovative uses which exploit the potential offered by CNFs in terms of the ability to be transparent, adhesive, water repellent, flame retardant and to conduct electricity.<\/div>
Cellulosa Microfibrillata<\/p>\n
\n
<\/div>\n<\/div>\n<\/div>
MFC has similar applications to CNFs but lower production times and costs, leading to a rather small reduction in overall properties.<\/div>[\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

and a second which exploits chemical hydrolosis, associated with operations for preparation, transformation, purification and functionlalisation to create cellulose nanocrystals (CNCs)<\/p>\n

Cellulose Nanocrystals (CNCs)

CNCs will be used in primary packaging for food<\/strong>, given their high oxygen barrier, aimed at increasing the shelf life of the foods packaged.<\/div>[\/vc_column_inner][\/vc_row_inner][vc_empty_space height=”15px”][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”center” background_image_as_pattern=”without_pattern” padding_top=”0″ padding_bottom=”50″ z_index=””][vc_column][vc_row_inner row_type=”row” type=”full_width” text_align=”left” css_animation=””][vc_column_inner width=”1\/3″][vc_single_image image=”841″ img_size=”full” alignment=”center” qode_css_animation=””][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”839″ img_size=”full” alignment=”center” qode_css_animation=””][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”1495″ img_size=”full” alignment=”center” qode_css_animation=””][\/vc_column_inner][\/vc_row_inner][vc_column_text]<\/p>\n

Micro-nanofibers are narrow bundles of long chains of amorphous or semi-crystalline cellulose. They have diameters in the range from 3 to 100nm and lengths that can reach tens of \u00b5m, their thermal expansion is as low as that of quartz, while their mechanical strength is five times that of steel.[\/vc_column_text][vc_empty_space height=”30px”][vc_column_text]Production will focus on the applicative specialization of nanofibrils<\/strong>, aiming to cover well-known areas of use as well as innovative uses.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_single_image image=”848″ img_size=”full” alignment=”center” qode_css_animation=””][vc_column_text]COATINGS made of cellulose nanocrystals on various plastic supports, to improve their properties.<\/em>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner row_type=”row” type=”grid” text_align=”left” css_animation=”” padding_top=”25″ padding_bottom=”25″][vc_column_inner width=”1\/2″]
WELL-KNOWN USES<\/div>[vc_empty_space height=”15px”][vc_column_text]<\/p>\n

the paper and cardboard segment<\/em> is an area of extensive use, in that the improved mechanical performances due to the use of nanofibrils bring an economic benefit thanks to the use of less cellulose per square metre of paper or cardboard produced (weighing less while offering the same performance<\/em>).<\/p>\n

[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″]

INNOVATIVE USES<\/div>[vc_empty_space height=”15px”][vc_column_text]<\/p>\n

these undoubtedly represent areas with a high added value<\/strong> on one hand and exclusive solutions<\/strong> on the other.<\/p>\n
