Abstract:
Biogas from agricultural residues presents a renewable energy solution for developing countries, reducing carbon emissions and supporting a circular economy. However, adoption remains slow due to high costs, limited expertise, feedstock shortages, and weak policies, leading to frequent failures of small-scale biogas systems reliant on mono-digestion of livestock manure. Effective feedstock selection is crucial for biogas plant efficiency, influencing design, costs, and sustainability. This study applies the Analytic Hierarchy Process (AHP) to prioritize and select sustainable feedstocks in Morocco’s Fès-Meknès region, evaluating them based on adequacy, supply consistency, and logistical ease. A survey identified cattle, sheep, chicken, and horse manure, along with wheat, barley, and maize straw, and fruit and vegetable waste as potential biogas plant feedstocks. AHP prioritization shows cattle manure, straw, and sheep manure ranking highest. Co-digestion of livestock manure and straw is therefore proposed as a solution to improve biogas plant performance, reduce abandonment rates, and enhance technology adoption. This approach strengthens biogas systems as viable renewable energy sources in developing countries, contributing to sustainable development goals.
