Abstract
Sustainable feed supply to anaerobic digestion (AD) plants is a significant challenge, particularly considering uncertainties in the energy demand market. This study proposes a new approach to feed scheduling and optimisation to address this challenge. A practical framework is proposed to determine the optimal co-digestion strategy for efficiently managing time-varying demands. Additionally, the research explores the impact of storage capacity and demonstrates the adaptability of the proposed model in contributing to emission reduction policies. Two case studies illustrate the model's flexibility and the impact of storage on increased productivity. The storage increase, results in a 23% reduction in gas grid reliance for the case study. Also, incorporating global warming potential in the objective function results in negligible changes to production metrics.
