Energy balance of different organic biogas farming systems [PDF]
The ecological impact of biogas plants depends on their integration into a given farming system. Therefore only farm-specific and no general statements are possible. In this paper, two different concepts of biogas production for an organic cash crop farm

ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Energy Efficiency of Biogas-Solar Plant
The consumption of thermal energy for heating the substrate in the process of biogas production represents a significant loss in the total energy balance that can be obtained from the biogas plant and further used as a produced energy. In addition, production process requires considerable additional energy spent for transport and biomass preparation as

Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Energy use and Green house gas emission in organic agriculture [PDF]
Reduction of fossil energy use has a two-fold aim namely reducing the dependence of a limited, non-renewable resource and reduction of emissions of green house gasses (GHG).

Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Contribution to the study of flocculation of digestate [PDF]
The paper deals with the intensification of separating the solid phase of digestate using flocculants only. The separated solid phase should subsequently be used in agriculture for fertilising.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.
