The Making and Characterization of Films from Avocado Seed Starch (Persea Americana Mill) and Polyvinyl Alcohol: A Sustainable Approach

Introduction

The world is facing a significant challenge in terms of waste management and environmental sustainability. The increasing demand for synthetic materials has led to a significant amount of waste, which not only harms the environment but also depletes natural resources. In this context, the development of sustainable materials from natural sources has become a pressing need. One such material is the film made from avocado seed starch (Persea Americana Mill) and polyvinyl alcohol (PVA). This article discusses the making and characterization of films from these two natural ingredients, highlighting their potential as a sustainable alternative to synthetic materials.

The Importance of Sustainable Materials

The use of natural ingredients in the production of films offers several benefits, including:

Economic benefits: Utilizing waste materials like avocado seeds reduces the cost of production and provides an economically viable alternative to synthetic materials.
Environmental benefits: Natural ingredients are biodegradable, non-toxic, and compostable, reducing the environmental impact of film production.
Innovation: The development of sustainable materials from natural sources opens up new opportunities for innovation and product development.

The Making of Films from Avocado Seed Starch and Polyvinyl Alcohol

The film making process involves two different approaches:

First approach: The film is produced from a mixture of avocado seed starch and polyvinyl alcohol.
Second approach: The film is produced from a mixture of avocado seed starch, polyvinyl alcohol, and glutaraldehyde.

The film is printed using a glass plate and dried in an oven at 30 °C. The resulting film is then characterized through various methods, including FT-IR, tensile strength test, SEM, water collection, and biodegradability test.

Characterization of Films

The characterization of films involves evaluating their physical and chemical properties. The FT-IR method is used to determine changes in chemical structures and interactions between materials. The tensile strength test measures how strong the film can be drawn without breaking up, while the SEM test gives a picture of the morality of the surface of the film. Testing water security shows how well the film can survive in moist conditions, while biodegradability measures the extent to which films can be decomposed naturally.

Results and Discussion

The results of this study show that films with a 95:5:0 formulation, which did not use glutaraldehyde, produced optimum mechanical properties. However, the 95:5:10 formulation that uses glutaraldehyde also shows a significant increase in film characteristics. The addition of glutaraldehyde plays an important role in improving the mechanical properties of the film, including morphology, tensile strength, water resistance, biodegradability, and purity through cross-bond reactions.

Conclusion

The making and characterization of films from avocado seed starch and polyvinyl alcohol opens up opportunities for innovation in the development of environmentally friendly materials. The addition of glutaraldehyde is proven to improve the mechanical properties of the film and provide promising results for broader use. Through this research, it is expected that the use of avocado seeds not only helps reduce waste but also creates products that can compete with conventional materials on the market. With the potential possessed, this film can be a sustainable solution for a more environmentally friendly industry.

Future Directions

The development of sustainable materials from natural sources is a rapidly growing field, and this study contributes to the growing body of research in this area. Future studies can focus on:

Scaling up production: Scaling up the production of films from avocado seed starch and polyvinyl alcohol to make them more commercially viable.
Improving mechanical properties: Further improving the mechanical properties of the film through the addition of other natural ingredients or modifications to the manufacturing process.
Exploring new applications: Exploring new applications for the film, such as food packaging, medical devices, or textiles.

By continuing to innovate and develop sustainable materials from natural sources, we can reduce our environmental impact and create a more sustainable future.
