Anaerobic digestion and microwave pyrolysis techniques for recycling organic wastes

Abstract

Two promising techniques – anaerobic digestion (AD) and microwave pyrolysis (MP) – have been presented in this work for possible recycling of organic waste. The main products of AD are biogas and digestate, which can be utilized for production energy, fuels and valuable materials. MP products are gases, liquids and char, which can be used as substrates for producing hydrogen, biodiesel, kerosene, and activated carbon. MP provides fast heating and can be used for various material waste blends including biomass – plastic mixtures. AD and MP can be combined for a synergic effect with respect to system efficiency.
