“…No data on energy surplus before codigestion was provided by Edelman et al (2000) . Biogas generated by a codigestion plant described by Kumke and Lanhans (2000) is supplied directly to engine‐generator sets to produce electrical power and thermal energy. Approximately 30% of the electrical energy was used to satisfy the requirements of the codigestion and adjacent facilities used for animal confinement.…”

“…In this case, energy recovery from biogas was not sufficient to meet the demand of other plant operations, which included denitrification and aeration of the liquid fraction of wastes and gasification and ash melting of the biosolids cake. The codigestion processes described by Kumke and Lanhans (2000) and Yoneyama and Takeno (2001) were implemented in plants that used codigestion from the start. Therefore, these plants had no data on the energy surplus before codigestion.…”

Codigestion of organic wastes is a technology that is increasingly being applied for simultaneous treatment of several solid and liquid organic wastes. The main advantages of this technology are improved methane yield because of the supply of additional nutrients from the codigestates and more efficient use of equipment and cost‐sharing by processing multiple waste streams in a single facility. Many municipal wastewater treatment plants (WWTPs) in industrialized countries currently process wastewater sludge in large digesters. Codigestion of organic wastes with municipal wastewater sludge can increase digester gas production and provide savings in the overall energy costs of plant operations. Methane recovery also helps to reduce the emission of greenhouse gases to the atmosphere. The goal of this literature survey was to summarize the research conducted in the last four years on anaerobic codigestion to identify applications of codigestion at WWTPs. Because the solids content in municipal wastewater sludge is low, this survey only focuses on codigestion processes operated at relative low solids content (slurry mode). Semi‐solid or solid codigestion processes were not included.    Municipal wastewater sludge, the organic fraction of municipal solid waste, and cattle manure (CAM) are the main wastes most often used in codigestion processes. Wastes that are codigested with these main wastes are wood wastes, industrial organic wastes, and farm wastes. These are referred to in this survey as codigestates. The literature provides many laboratory studies (batch assays and bench‐scale digesters) that assess the digestibility of codigestates and evaluate the performance and monitoring of codigestion, inhibition of digestion by codigestates, the design of the process (e.g., single‐stage or two‐stage processes), and the operation temperature (e.g., mesophilic or thermophilic). Only a few reports on pilot‐ and full‐scale studies were found. These evaluate general process performance and pretreatment of codigestates, energy production, and treatment costs.

“…By practicing co-digestion the producer gains additional revenue through a combination of received tipping fees, additional biogas production, and the resulting increase in received green tags. Co-digestion of manure with various substrates has been actively researched at laboratory and pilot-scale [10][11][12][13][14][15][16][17][18][19][20][21] with a few studies completed at commercial-scale [7,22,23]. These studies conclude that manure with its high alkalinity and availability of macro-and micro-nutrients generates positive synergisms with many received substrates, which allows for significant enhancement of biogas productivity.…”

Die komplexe und heterogene Struktur von ionischen Flüssigkeiten wurde in den vergangenen Jahren aufgezeigt, ihre Auswirkung auf die Dynamik blieb jedoch offen. Hier verwenden wir Femtosekunden‐IR‐Spektroskopie, um die lokale strukturelle Dynamik in protischen Alkylammonium‐basierten ionischen Flüssigkeiten aufzuklären. Die Strukturrelaxation nach einem ultraschnellen Temperatursprung, der auf die Schwingungsanregung und Schwingungsrelaxation der N‐D‐ (oder N‐H‐Streckschwingung) folgt, ist in den ionischen und hydrophoben Unterstrukturen sehr unterschiedlich. Die Dynamik der ionischen Domänen wird durch die Länge der Alkylkette kaum beeinflusst und ist folglich von der Viskosität entkoppelt. Die Relaxation in den hydrophoben Bereichen, die durch die Dynamik der C‐H‐Streckschwingung zugänglich ist, ist um einen Faktor zwei schneller als die Dynamik in den ionischen Bereichen und zeigt eine bemerkenswert niedrige thermische Aktivierungsenergie.

Abstract. Different raw organic materials can be used for production of methane in the anaerobic fermentation process. Every kind of biomass has the specific methane production potential. In practice, different biomasses are utilised in the biogas plant at the same time often, so enabling co-fermentation at different proportions. The purpose of this study was to ascertain how the co-fermentation of various biomasses affects the methane yield compared to methane release from the same biomass during its mono-fermentation. Different factors may influence the methane yield, and most important are carbon: nitrogen (C: N) ratio, presence of easy degradable carbohydrates, trace elements and other substances needed to provide optimal microbial activity. Investigations were provided in 16 bioreactors with volume 0.75 l operating in batch mode at the temperature 38°C. Equal amounts of the carrots, grain drying residue, potato chips and inoculums were processed in 3 different groups of bioreactors to observe methane production from individual biomass, mixed with inoculums, in the monofermentation process. The same biomasses, in proportion 1:1:1 by weight, and inoculums were mixed together and co-fermented in the fourth group of bioreactors. 2 bioreactors were filled with inoculums only for control. It was found that average specific methane production per gram of dry organic matter in the co-fermentation process was higher compared to average specific methane production obtained from the same biomasses (carrots and grain residues) in the mono-fermentation process, when each biomass was fermented individually.
