The Use Of Polyester Amide In Bioplastic Soybean Protein From Tofu Industrial Solid Waste With Glycerol As A Plastic Material
The Use of Polyester Amide in Bioplastic Soybean Protein from Tofu Industrial Solid Waste with Glycerol as a Classical Material
Introduction
The world is facing a significant challenge in managing waste, particularly in the industrial sector. The increasing amount of waste generated by industries has led to environmental pollution and health hazards. In recent years, there has been a growing interest in developing biodegradable plastics, also known as bioplastics, as an alternative to traditional plastics. Bioplastics are made from renewable resources such as plants, microorganisms, or agricultural waste. In this study, we aim to explore the characteristics of bioplastic films made from soybean protein, glycerol, and polyester amide, and to determine the optimal ratio between the three components in making bioplastic from tofu industrial solid waste.
The Importance of Glycerol in Bioplastic Films
Glycerol is a crucial component in making bioplastic films. It can improve the mechanical properties and flexibility of the film. In this study, we found that the most optimal concentration of glycerol was 15% of soy protein. The test results show that in the combination of soy protein, glycerol, and amide polyester as much as 30%, this bioplastic film reaches a tensile force of 8.886 MPa and the percentage of elongation is 170,588%. This number indicates that the balance between molecular components in bioplastic films can affect attractiveness and flexibility.
The Role of Polyester Amide in Bioplastic Films
Polyester amide is a type of biodegradable plastic that can be used to improve the properties of bioplastic films. However, research shows that the addition of polyester amide causes a decrease in protein levels in bioplastic films. This shows that an increase in the proportion of polyester amide can result in a decrease in protein integrity as a major component of the film. Therefore, it is essential to determine the optimal ratio between soy protein, glycerol, and polyester amide in making bioplastic films.
Hot Resistance of Bioplastic Films
Hot resistance is another important aspect in assessing the quality of bioplastic films. Data from testing using Thermogravimetric Analysis (TGA) shows that bioplastic films from soy protein, glycerol, and polyester amide have a residue of 24.31%. This indicates that the film has a good thermal nature and heat resistance, which is an important characteristic for industrial applications.
Biodegradability of Bioplastic Films
From the point of view of biodegradability, bioplastic films from soy protein and polyester amide show interesting performance. The lower degree of amide polyester crystallization compared to soy protein causes the highest biodegradation rate of bioplastic films seen in a combination of 50% polyester amide. This shows that the right composition can help speed up the degradation process, which is a very desirable characteristic in the context of environmental sustainability.
Surface Analysis of Bioplastic Films
Surface analysis using an electron scanner (SEM) microscope shows that the surface morphology of soybean protein has a globular structure, which shows an equitable distribution of film components. In addition, the results of infrared spectroscopy analysis (FTIR) revealed the physical interaction between these components, especially the presence of hydrogen bonds (O-H), although no new functional groups were found in the bioplastic film.
Conclusion
By paying attention to the results of this study, it can be concluded that the combination of soy protein, glycerol, and polyester amide has excellent potential as an environmentally friendly bioplastic material. The use of tofu industrial solid waste not only provides solutions to waste management, but also contributes to the development of sustainable bioplastic raw materials and has adequate properties for various applications.
Recommendations
Based on the results of this study, the following recommendations can be made:
- Further research is needed to optimize the ratio between soy protein, glycerol, and polyester amide in making bioplastic films.
- The use of tofu industrial solid waste as a raw material for bioplastic production should be promoted.
- The development of bioplastic films with improved properties, such as hot resistance and biodegradability, should be continued.
Future Directions
The use of bioplastics is a promising solution to the environmental problems caused by traditional plastics. However, there are still many challenges to be overcome, such as the high cost of production and the limited availability of raw materials. Therefore, further research is needed to develop more sustainable and cost-effective bioplastic materials.
Limitations of the Study
This study has several limitations, including:
- The study was conducted on a small scale, and further research is needed to confirm the results.
- The study only focused on the properties of bioplastic films made from soy protein, glycerol, and polyester amide, and further research is needed to explore the properties of bioplastics made from other raw materials.
Conclusion
In conclusion, this study has shown that the combination of soy protein, glycerol, and polyester amide has excellent potential as an environmentally friendly bioplastic material. The use of tofu industrial solid waste not only provides solutions to waste management, but also contributes to the development of sustainable bioplastic raw materials and has adequate properties for various applications. Further research is needed to optimize the ratio between soy protein, glycerol, and polyester amide in making bioplastic films and to develop more sustainable and cost-effective bioplastic materials.
