Exergy analysis of solar energy assisted biogas plants for Turkey
The energy quality of solar energy assisted biogas plants established in Izmir, Turkey was investigated in this study via exergy analysis. This study was assisted together with other energy and economy analysis of these plants. Firstly, the plant was operated at mesophilic temperature region and it was continuously fed with cattle manure. The biogas efficiency reached a value as high as 1.3 ...

The feasibility of trace element supplementation for stable operation of wheat stillage-fed biogas tank reactors
The aim of this study was to investigate the effect of trace element supplementation on operation of wheat stillage-fed biogas tank reactors. The stillage used was a residue from bio-ethanol production, containing high levels of sulfate. In biogas production, high sulfate content has been associated with poor process stability in terms of low methane production and accumulation of process ...

Anaerobic digestion of macroalgae: methane potentials, pre-treatment, inhibition and co-digestion
In the present study we tested four macroalgae species – harvested in Denmark – for their suitability of bioconversion to methane. In batch experiments (53 °C) methane yields varied from 132 ml g volatile solids−1 (VS) for Gracillaria vermiculophylla, 152 ml g VS−1 for Ulva lactuca, 166 ml g VS−1 for Chaetomorpha linum and 340 ml g VS−1 for Saccharina latissima following 34 days of incubation. ...

Biogas and Anaerobic Digestion in Relation to CH4 Methane Monitoring
The use of biogas as a renewable energy source currently accounts for 10 % of global primary energy consumption1 and is often heralded as the perfect example of the ‘circular economy’ – where waste products can be reused to generate energy for other processes in a self-perpetuating cycle.2Biogas consists of the mixture of gases produced by the breakdown of organic matter by bacteria under ...
