Valorisation of invasive plant species in the production of polyelectrolytes

Production of nanocellulose gels and films from invasive tree species

“…The two bleached kraft pulps differed slightly in the chemical composition, with a higher cellulose content and a lower xylan content having been obtained for A. altissima pulp, similarly to the trend observed for the unbleached kraft pulps [24]. The total lignin content was practically the same and the Klason lignin was insignificant in both cases.…”

High-performance delignification of invasive tree species wood with ionic liquid and deep eutectic solvent for the production of cellulose-based polyelectrolytes

“…The cationicity index values here obtained are in the same order of magnitude of those reported for kraft pulp cationization, especially when it was used a GT/aldehyde ratio of 4 for the cationization of DES-DALC (3.6 mmol g −1 for the main fraction). For a kraft pulp with 2.2% of lignin, Almeida et al 38 obtained 3.6 mmol g −1 of cationic group content using a similar GT/aldehyde ratio.…”

“…, 1241 cm 3 g −1 for a pulp with kappa number of 15). 38 It seems that the IL and DES pretreatments lead to a higher cellulose depolymerization than the kraft cooking, which can be an advantage depending of the subsequent application.…”

Strategies for the Management of Aggressive Invasive Plant Species

“…Invasive waste can also be used to produce bioenergy, namely bioethanol, biogas, or wood fuel (e.g., [133][134][135][136][137][138][139][140][141][142][143][144][145][146][147][148]), biochar or charcoal for different purposes (e.g., [149][150][151][152][153]), or animal feed (e.g., [154][155][156][157]. Some authors also suggest the use of IAPs for effluent treatments (e.g., [158][159][160][161][162][163][164][165]), paper and packaging materials (e.g., [166][167][168][169][170]), building materials [171], natural fiber composites [172], and bio-adsorbents for textile dyes or others [173][174][175][176][177][178][179]…”
