Designing Dry Fermentation Process to Generate 1 MW Electricity by Using Organic Waste-A Theoretical Study for Dammam, Saudi Arabia
This study aims to elaborate the scenario of using a food waste mixture of whey, potato waste, and corn waste to generate biogas after anaerobic digestion process in a plug-flow digester. The process is designed to generate 1MW of electricity. Then the resulted digestate material from the plug-flow reactor will be composted in a windrow composting process to use as a fertilizer. The scenario results showed that the generated electricity from the biogas will serve a number of 327 homes in the study region. In addition, there will be a compost production of about 7,027 tons per year. Finally, a net greenhouse gas reduction of 5,813.4 tons CO2-eq.per year is estimated for the whole process.
