Introduction

Food waste presents a significant environmental and economic challenge globally. Landfilling food waste contributes to greenhouse gas emissions and leachate contamination, while its loss represents a waste of resources. Anaerobic Digestion (AD) offers a promising solution by converting food waste into biogas, a renewable energy source, and digestate, a valuable fertilizer. This course aims to provide participants with the knowledge and skills to design, implement, and operate efficient and sustainable Food Waste-to-Energy (FWtE) systems using AD technology. The course will cover all aspects of FWtE, from feedstock management to biogas utilization and digestate management. It will emphasize practical applications, case studies, and best practices to ensure participants can effectively address the challenges and opportunities in this rapidly growing field. This course will empower participants to contribute to sustainable waste management practices and the development of renewable energy resources through innovative FWtE solutions.
