Posouzení životního cyklu produkce nanocelulózy ze dřeva : případová studie pro Českou republiku
 Pajdla, Marek
This diploma thesis focuses on understanding the nanocellulose and production routes of this nano-scale cellulosic material. In the literature review, there is an overview of different production routes including pretreatment and treatment processes of biomass fibers and list of main global producers of nanocellulose currently available on the market. The practical part includes collected cost inputs for four different production scenarios which are: (1) enzymatic pretreatment with microfluidization treatment, (2) carboxymethylation pretreatment with microfluidization treatment, (3) enzymatic pretreatment with high-pressure homogenization treatment and (4) carboxymethylation pretreatment with high-pressure homogenization treatment. Costs of these four production routes are compared for three locations in the Czech Republic and contrasted with the cost of purchase of nanocellulose from abroad.
