Abstract

Abstract: Anaerobic digestion is a widely employed technique that converts waste into biogas, which can be employed as renewable energy. To improve its efficiency, but also to treat recalcitrant waste, mixes involving several types of feedstock with different biodegradability rates are fed to the process. Finding the proper mix is difficult and involves extensive, long-lasting experimental work. This paper presents an approach which allows determining the mix with desired properties based on Biochemical Methane Potential (BMP) tests, chemical composition of the feedstocks and optimization. This procedure is illustrated based on experimental data gathered from BMP tests on leaves of linden, oak and maple, and meadow. Subsequently, a simple model is used to simulate the continuous operation of the process converting the proposed mixes into methane.
