Corn Cob (Zea mays) and Rice (Oryza sativa l.) Hulls as Bio Pots an Alternative to Single-use Plastic Pots

Abstract

Global plastic production has surged in recent decades, exacerbating the environmental crisis due to its persistent presence and slow degradation. This parallels the environmental challenge agricultural waste poses, often improperly disposed of. On the other hand, biodegradable pots offer a sustainable alternative to plastic pots by decomposing naturally in the soil, reducing waste, and promoting soil health. Thus, this research investigated the feasibility of repurposing agricultural waste such as corn cob and rice hulls into biodegradable alternatives to conventional plastic pots. This study aimed to determine the mechanical performance of biodegradable pots in terms of tensile strength, compressive strength, and compressive strength (peak force). Additionally, comparing its mechanical properties to commercially available pots in the market. A quantitative research approach was employed, utilizing experimental methodologies and the Kruskal-Wallis test to assess differences between the materials. The analysis revealed that the bio-pots exhibited a tensile strength within the 0.1 MPa to 0.3 MPa range. Furthermore, compressive strength demonstrated an average of 0.4 MPa with a maximum peak force of 2625.2 N. The Kruskal-Wallis test result revealed a P-value of (.392), indicating no statistically significant difference in tensile and compressive strength compared to commercially available plant pots. These findings collectively suggest that the fabricated bio-pots possess the potential to be viable alternatives. However, further research and development are necessary to optimize their properties and enhance their performance. Consequently, by utilizing agricultural byproducts, this research contributes to mitigating environmental impact and promoting sustainability in agriculture.
