Analyzing the Ecological Footprint of Dry Chemical Silage Derived from Red Tilapia (Oreochromis spp.) Viscera – A Case Study Utilizing Ecological Footprint Methodology

The global increase in fish production, driven by growing populations and consumer interest, has brought forth environmental challenges, particularly in the form of waste generated by the industry. Notably, the disposal of viscera has emerged as a significant contributor to negative environmental impacts. This study focuses on assessing the environmental repercussions associated with obtaining dry chemical silage from the viscera of red tilapia (Oreochromis spp.), employing the ecological footprint methodology as a comprehensive indicator of sustainability. The utilization of ecological footprint methodology in this context allows for a holistic evaluation of the environmental consequences linked to the entire lifecycle of the process. It goes beyond a narrow focus on individual pollutants, considering the broader ecological impact of the entire production chain. The findings reveal that the conversion of fish viscera into dry chemical silage brings about a noteworthy reduction, approximately 30%, in carbon dioxide (CO2) emissions compared to the alternative scenario where fresh viscera are simply discarded into shallow landfills. This reduction is a critical aspect of environmental sustainability, given the role of CO2 in contributing to climate change. Moreover, the study identifies specific actions that can be implemented to further enhance the sustainability of this process. For instance, incorporating measures like biogas production from waste and employing solar drying techniques for the final product can lead to an impressive mitigation of approximately 86% of the overall environmental impact. This emphasizes the importance of adopting innovative and eco-friendly practices in the production and waste management stages of the process. In conclusion, the research establishes that the production of dry chemical silage from red tilapia viscera, especially when utilizing alternative drying energy sources, is environmentally sustainable. This insight is valuable not only for the aquaculture industry but also for broader discussions on sustainable practices within the context of food production and waste management. The study highlights the significance of considering the entire ecological footprint and implementing strategic measures to minimize environmental impact, contributing to the ongoing global efforts towards sustainable development.
