This study investigates the life cycle assessment (LCA), environmental impact, and economic feasibility of Solar Tunnel Dryers (STDs) in hot regions, with a focus on their potential for generating carbon credits. Solar Tunnel Dryers, which harness renewable solar energy for drying agricultural products, offer a sustainable alternative to conventional drying methods that rely on fossil fuels and electricity. The LCA examines the entire life cycle of STDs, from material extraction and manufacturing to operation and disposal, to quantify their environmental benefits. The study compares these benefits with those of traditional drying methods, highlighting significant reductions in greenhouse gas emissions and energy consumption. Furthermore, the economic feasibility analysis evaluates the cost-effectiveness of STDs, considering factors such as initial investment, operational costs, and product quality. The potential for generating carbon credits through reduced emissions is also assessed, providing an additional revenue stream that enhances the financial attractiveness of STDs. The findings suggest that STDs are not only environmentally beneficial but also economically viable, particularly in regions with high solar insolation. This research supports the adoption of STDs as a sustainable and profitable solution for agricultural drying, contributing to climate change mitigation and rural development.
