Calculation of the carbon footprint of valex vegetable tannin product used as an alternative chemical in the tanning process in the leather industry and reduction proposals

Abstract

The primary objective of this thesis is to calculate the carbon footprint of the Valex vegetable tannin product, used as an alternative chemical in the leather tanning process, and to propose reduction strategies. The study focuses on analyzing the production processes of Valex in the Aegean Region of Turkey, specifically Manisa, and aims to quantify the carbon dioxide equivalent (CO2e) greenhouse gas emissions. The carbon footprint calculation is grounded in the GHG Protocol and the ISO 14064- 1 and ISO 14067 standards. The scope of this research includes examining the importance of the leather industry, identifying the sources of greenhouse gas emissions within the industry, and evaluating the environmental impact of the Valex vegetable tannin product compared to traditional tanning agents. The study highlights the significant contribution of the leather industry to global greenhouse gas emissions and emphasizes the need for sustainable practices. To achieve its objectives, the study meticulously analyzes the production stages of Valex, from raw material collection to the final product. This includes the collection and transportation of acorns, their processing into tannin, and the emissions generated at each stage. By identifying the major contributors to the carbon footprint, the study proposes strategies to reduce emissions, such as optimizing energy consumption and exploring alternative fuels. The findings of this thesis aim to provide insights into the environmental impacts of the Valex vegetable tannin product and offer recommendations for reducing the carbon footprint of the leather industry. By comparing Valex with other materials, the study seeks to understand its advantages and suggest improvements for more sustainable leather production practices. In conclusion, this research contributes to the literature by evaluating the environmental performance of Valex vegetable tannin and proposing methods to mitigate its impact. The results are intended to serve as a reference for future studies and practical applications, promoting more sustainable and eco-friendly practices in the leather industry.
