In this lesson, you’ll find out about the feedstocks used in anaerobic digestion (AD), such as agricultural waste, food waste, and wastewater sludge. You’ll explore different types of digesters (batch, continuous, single-stage, and multi-stage) and understand biogas composition, including methane and carbon dioxide. Real-world examples of full-scale AD systems will also be covered, demonstrating how waste is converted into renewable energy.
