Organinių atliekų biodestrukcijos proceso metu išsiskiriančių biodujų eksperimentiniai tyrimai

Abstract

Anaerobic digestion is a process when the organic matter is broken down by microbes in a sealed oxygen-free environment. The process of anaerobic digestion consists of three steps. The first step is the decomposition (hydrolysis) of the plant or animal matter. This step breaks down the organic matter to usable-sized molecules, such as sugar. The second step is the conversion of the decomposed matter to organic acids. And finally acids are converted to biogas. The products of the process are biogas and compost. Biogas consists of 60–65 % of methane. Due to its high heating value gas is a valuable source of energy with a large scope of application. The biogas production is far surpassing the energy demand of the plant itself. Converted into electricity the surplus can be fed into a public network. A short aerobical treatment (a normal composting process) follows the anaerobic process. Due to its structure, a high percentage of the organic matter and its good balance of nutrients, the resulting compost has a large range of agricultural and horticultural applications. [...].
