Abstract. In this study, the effect of recycled organic waste thermal insulation materials and insulation thickness on a double air pass solar tunnel dryer performance for the charcoal briquette drying process was investigated based on the heat transfer model, that was computed with Python code. The result reveals that, an average temperature of bagasse insulated a double air pass solar tunnel dryer was higher than wood, paper, corn cop, and sawdust insulation by 17.5%, 12%, 8.3%, and 6%, and higher than rock wool, mineral wool, and glass fiber by 3.01%, 4%, and 25.41%, respectively. The energy and exergy efficiency were considerably enhanced with bagasse insulation, comparatively. Thus, the assimilation of recycled organic waste thermal insulation materials enhances the evaporation rate besides reducing energy and exergy losses to the ambient while concomitantly minimizing costs and environmental impacts.
