Methane emissions from digestate at an agricultural biogas plant
Bioresource Technology, 2016Methane (CH4) emissions were measured over two years at an earthen storage containing digestate from a mesophilic biodigester in Ontario, Canada. The digester processed dairy manure and co-substrates from the food industry, and destroyed 62% of the influent volatile solids (VS).

Renewable and Sustainable Energy Reviews, 2012
Abstract The formal and legal requirements as well as the support system for building agricultural biogas plants in Poland have been presented. There are currently 24 agricultural biogas plants operating in Poland. The fermentation substrates are slurry, food waste and maize silage. It is most often mesophilic fermentation.

The effect of substrate on the amount and composition of biogas in agricultural biogas plant
Infrastruktura i Ekologia Terenów Wiejskich / Infrastructure and ecology of rural areas, 2015Construction of biogas plants processing agricultural waste enables to reduce waste, limit emission of gases and odors in rural areas as well as gives the possibility to ensure self-sufficiency of energy. The amount of generated electricity and heat depends on the quantity and quality of biogas.

Degradation efficiency of agricultural biogas plants – A full-scale study
Bioresource Technology, 2015The degradation efficiency of 21 full-scale agricultural CSTR biogas plants was investigated. The residual methane potential of the digestion stages was determined in batch digestion tests (20.0 and 37.0 °C). The results of this study showed that the residual methane yield is significantly correlated to the HRT (r=-0.73). An almost complete degradation

Biodrying of the Digestate from Agricultural Biogas Plants
Annual Set The Environment Protection, 2015Anaerobic digestion residue represents a nutrient rich resource which, if applied back on land, can reduce the use of mineral fertilizers and improve soil fertility. However, dewatering of digestate may be recommended in certain situation. Limited applicability of digestate as fertilizer may appear, especially in winter, during the vegetation period or
