Agricultural biogas plants based on energy crops gain more and more importance because of numerous energetic, environmental and agricultural benefits. In contrast to older biogas plants, the newest generation of biogas plants is equipped with modern ICA equipment and reliable machines/engines. In this paper, the authors present technical details and operational results of a modern full-scale ag...

Grass is generally considered as one of the major agricultural products and covers over 90% of Irish agricultural land. While useful as an animal feedstock it can also be used for energy production. Here batch mesophilic anaerobic digestion of grass silage was studied. The methane concentration in the biogas clearly showed that grass silage has a high affinity to produce a high quality methane ...

Agricultural residues are intensively evaluated as potential feedstocks for biogas plants. Vegetable crops generate massive during and at the end of their growing seasons. A greenhouse facility in Greece, Thrace Greenhouses S.A., generates 7000–8000 t per year residual green biomass, resulting from hydroponic cultivation tomatoes cucumbers on 170,000 m2 land February to November. The crop inclu...

Trametes hirsuta is an efficient lignin-degrading species due to its ability to produce laccase and Mn-dependent peroxidase. Agricultural residues represent prospective substrates for the bioconversion into fungal biomass and lignocellulolytic enzymes, but also they could be potential environmental pollutants. Evaluation of the potential of T. hirsuta to produce ligninolytic enzymes during soli...

The research explores the possibilities of biogas extraction from aquaculture waste. Samples fish-farming pool sludge were taken a fish farm, which is located in Krāslava district, Kalnieši rural municipality. Prior to experimental fermentation and biogas, samples analyzed order determine their moisture organic matter content (OMC). For purpose increasing OMC available for fermentation, was mix...
