High-temperature fermentation (HTF) of ethanol can reduce costs cooling, sterilization, and related equipment compared to the general fermentation.

Addressing the agricultural challenges of agri-food waste accumulation, this study assessed energy potential green residues from tomato (Solanum lycopersicum L. cv. Kmicic) plants in different fertilizer configurations and Shea nutshell (Vitellaria paradoxa) waste. Two key parameters were compared: (I) Calorific Value (CV), representing thermal treatment, (II) Biogas Biomethane production potential, biochemical treatment. Potential was estimated using Baserga method fermentable organic matter (FOM) method. Additionally, effect fertilization on elemental composition its analyzed. showed better properties for both utilization, with a CV 16.29 MJ/kg. The FOM methods estimation that highest yields 504.18 671.39 LN/kg DM, respectively. Among fertilized residues, volcanic tuff additive resulted an optimal C/N ratio (28.41) high 457.13 DM (Baserga) 542.85 (FOM). These findings demonstrate feasibility employing as promising feedstock production.
