depleting. Also important is the development of more environmentally friendly production process for production of cellulosic man-made textiles. These newer methods
eliminate the need for toxic compounds such as CS 2 and minimize the total amount of
chemicals such as sodium hydroxide required for the production process (Shen et al.
2010). Aquatic-sourced cellulose from aquatic plants which are growing abundantly
and are seen as environmental nuisance means relatively low-cost feedstock for commercial cellulose production. Recent studies have shown that high-quality cellulose
nanoparticles (Jaurez-Luna et al. 2019) with low aggregation can be extracted from
the water hyacinth stem.
14.9 Conclusion
Cellulose is relatively abundant in the aquatic ecosystem as it can be obtained from a
diverse range of plants and algae. Some cellulose-producing species of aquatic plants
and animals are so abundant that they have become a nuisance to water transportation
and coastal activities. Extraction of cellulose from aquatic source presents one of the
solutions to address such challenges. There needs to be a balanced system in place,
whereby the aquatic plants re-absorb the nutrients from the wastewater released by
industries such as paper and textile, among others, and then these aquatic plants in
return act as sources of polymers such as cellulose which in turn serves as a source
of fuel and feedstock for these industries. The superior quality of cellulose obtained
from aquatic plants and algae indicates future potential in their high-value application
in biomedicine and pharmacology.
