Thesis Abstract
The proliferation of plastic packaging materials has led to significant environmental pollution, necessitating the development of sustainable and eco-friendly alternatives derived from renewable agricultural residues. This study aims to design, produce, and evaluate a biocomposite packaging material utilizing agricultural waste such as rice husks, wheat straw, and maize stalks, with the overarching goal of addressing environmental degradation caused by conventional plastics. The specific objectives include characterizing the physicochemical properties of selected agricultural residues, developing biocomposite formulations through a combination of natural binders (such as starch and cellulose derivatives), and assessing the mechanical, thermal, and biodegradability performance of the resulting biocomposites. A mixed-methods research design was employed, integrating experimental laboratory analyses with qualitative assessments. The study focused on a population comprising agricultural residues collected from three major farming regions, with a targeted sample size of 150 samples for physicochemical characterization and 60 biocomposite prototypes developed for performance testing. Data collection involved standardized laboratory procedures, including Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Thermogravimetric Analysis (TGA) to determine chemical, morphological, and thermal properties. Mechanical testing followed ASTM standards for tensile strength, flexural strength, and impact resistance, while biodegradability was assessed through soil burial tests over 90 days. The data analysis utilized ANOVA to compare properties across different formulations, correlation analysis to examine the relationship between residue composition and mechanical performance, and thematic analysis of qualitative feedback from industry stakeholders regarding practical usability. Anticipated findings include the identification of optimal biomass-to-binder ratios that yield biocomposites with tensile strength exceeding 10 MPa, bio-based thermal stability comparable to conventional plastics, and degradation rates aligned with environmental standards for packaging materials. The research expects to demonstrate that biocomposites reinforced with rice husks and wheat straw outperform those with maize stalks in mechanical robustness, while all formulations exhibit significantly higher biodegradability than conventional polymers. The findings are expected to elucidate the critical influence of fiber-matrix interface quality and residue composition on performance, thereby contributing valuable insights for material optimization. This study contributes to existing knowledge by advancing the understanding of agricultural residue-based biocomposite formulation and establishing performance benchmarks relevant to commercial packaging applications. It applies Glass’s and Hoppock's theories of sustainable material development, underpinning the eco-design approach within the circular economy framework. The research further aligns with the Theory of Planned Behavior by exploring stakeholder perceptions related to the adoption of biocomposites, providing a foundation for policy recommendations aimed at promoting biodegradable packaging solutions. In conclusion, the research affirms the feasibility of utilizing locally sourced agricultural residues in the development of environmentally friendly packaging materials that meet industrial performance standards. Based on the findings, recommendations include the promotion of integrated residue collection systems, incentivization of biocomposite manufacturing, and the formulation of standards for biodegradable packaging. Future investigations should focus on scaling up production processes, life cycle assessment, and exploring the economic viability of biocomposite commercialization to facilitate widespread adoption and contribute to sustainable waste management practices globally.
Thesis Overview
This research focuses on developing environmentally friendly packaging materials made from agricultural waste, such as straw, husks, or stalks. Traditional packaging materials like plastics are convenient but cause significant environmental pollution because they do not decompose easily and often end up in landfills and oceans. Biocomposites, which combine natural fibers with biodegradable matrices, offer a promising alternative that is both sustainable and functional. The study aims to design a biocomposite packaging material that utilizes readily available agricultural residues, making it cost-effective, biodegradable, and eco-friendly.
The research addresses a gap in knowledge related to creating effective biocomposite materials from specific local agricultural residues, evaluating their mechanical properties, and understanding their suitability for packaging use. This involves exploring how different natural fibers and binding agents interact to influence the strength, flexibility, and durability of the final product. The researcher will follow a step-by-step process, beginning with the collection of agricultural residues from local farms, followed by processing and preparing these fibers for composite production.
Laboratory experiments will then be conducted to produce various formulations of biocomposites. The properties of these samples will be tested using techniques such as tensile testing, water absorption analysis, and biodegradability assessments. Data will be analyzed statistically using methods like ANOVA to compare the performances of different formulations. The researcher will also evaluate the environmental impact and cost-effectiveness of the best-performing biocomposites.
The contribution of this study will be in providing a scientifically validated method for producing biodegradable packaging materials from agricultural waste, which could replace less sustainable options in the market. The expected outcome is a set of optimized biocomposite formulations that meet industry standards for packaging strength and durability while reducing environmental impact. Ultimately, the research will support the shift toward sustainable packaging solutions and promote the value of agricultural residues as raw materials for new materials.
