Abstract
Water hyacinth is an invasive aquatic plant that causes adverse effects on the global environment. Due to high cellulose contents of water hyacinth, in this project aimed to covert water hyacinth to valuable raw materials for CMC-based bioplastic. Not only does the excess amount of water hyacinth reduces from natural water resources, but biodegradable CMC-bioplastic can also decrease the amount of plastic waste. Cellulose was extracted from water hyacinth followed by synthesis of carboxymethylcellulose (CMC) and preparation of bioplastic films, respectively. Gamma irradiation (1-10 kGy) was used to induce the crosslinking of CMC chains to improve the CMC bioplastic properties. The synthesized CMC from water hyacinth has comparable properties to the commercial CMC in that similar thermal stabilities, elemental components, and degradation mechanisms under controllable artificial weathering process. Further research regarding the role of CMC bioplastic derived from water hyacinth for food packaging would be promising applications.

The article you provided, identified by the code "1742-6596/1719/1/012110," addresses the conversion of water hyacinth, an invasive aquatic plant, into valuable raw materials for carboxymethylcellulose (CMC)-based bioplastics. The primary goal of this project is twofold: first, to reduce the excess amount of water hyacinth in natural water resources, and second, to produce biodegradable CMC-based bioplastic, consequently mitigating plastic waste.
Here's a breakdown of the key concepts and processes discussed in the article:
-
Water Hyacinth as an Invasive Species: Water hyacinth is identified as an invasive aquatic plant that poses adverse effects on the global environment. The article emphasizes the need to address the overgrowth of water hyacinth to prevent its negative impact on ecosystems.
-
Cellulose Extraction from Water Hyacinth: The project involves extracting cellulose from water hyacinth. Cellulose, a major component of plant cell walls, serves as a crucial raw material for the subsequent synthesis of carboxymethylcellulose (CMC).
-
Synthesis of Carboxymethylcellulose (CMC): Following cellulose extraction, the article describes the synthesis of carboxymethylcellulose (CMC). This process likely involves the modification of cellulose through carboxymethylation, enhancing its properties for bioplastic production.
-
Preparation of Bioplastic Films: Once CMC is synthesized, the next step involves the preparation of bioplastic films. This stage likely includes transforming the modified cellulose into a form suitable for the production of biodegradable plastic.
-
Gamma Irradiation for Crosslinking: Gamma irradiation, with a specified range of 1-10 kGy, is employed to induce the crosslinking of CMC chains. This step is crucial for improving the properties of CMC-based bioplastic, potentially enhancing its strength and stability.
-
Comparison with Commercial CMC: The article highlights that the synthesized CMC from water hyacinth exhibits comparable properties to commercial CMC. These properties include thermal stabilities, elemental components, and degradation mechanisms under controlled artificial weathering processes.
-
Potential Applications in Food Packaging: The concluding part of the article suggests that further research should explore the application of CMC-based bioplastic derived from water hyacinth in food packaging. This indicates a potential avenue for practical applications and commercial use.
In summary, the research described in the article demonstrates a holistic approach to addressing environmental issues caused by water hyacinth through the production of sustainable and biodegradable CMC-based bioplastics. The integration of gamma irradiation and the comparison with commercial CMC highlight the depth of the study, paving the way for promising applications, particularly in the field of food packaging.
