• The current Nordic biogas and biofertilizer potential : An inventory of established feedstock and current technology
  Biogas solutions in the Nordics is undergoing rapid developments and the demand for biogas is ever increasing because of the Russian war on Ukraine and the transition to fossil free industry and transportation. Furthermore, with the introduction of several multi-national companies into the biogas sector in the Nordics and with more and more biomethane being […]

• Absence of oxygen effect on microbial structure and methane production during drying and rewetting events
  Natural environments with frequent drainage experience drying and rewetting events that impose fluctuations in water availability and oxygen exposure. These relatively dramatic cycles profoundly impact microbial activity in the environment and subsequent emissions of methane and carbon dioxide. In this study, we mimicked drying and rewetting events by submitting methanogenic communities from strictly anaerobic environments […]

• Critical method needs in measuring greenhouse gas fluxes
  Reaching climate goals depends on appropriate and accurate methods to quantify greenhouse gas (GHG) fluxes and to verify that efforts to mitigate GHG emissions are effective. We here highlight critical advantages, limitations, and needs regarding GHG flux measurement methods, identified from an analysis of >13 500 scientific publications regarding three long-lived GHGs, carbon dioxide (CO2), […]

• Overexpression of a soybean Globin (GmGlb1-1) gene reduces plant susceptibility to Meloidogyne incognita
  Non-symbiotic globin class #1 (Glb1) genes are expressed in different plant organs, have a high affinity for oxygen, and are related to nitric oxide (NO) turnover. Previous studies showed that soybean Glb1 genes are upregulated in soybean plants under flooding conditions. Herein, the GmGlb1-1 gene was identified in soybean as being upregulated in the nematode-resistant […]

• Comprehensive Meta-Analysis of Pathways to Increase Biogas Production in the Textile Industry
  The textile industry is one of the largest environmental polluters in the world. Although waste management via anaerobic digestion (AD) is a sustainable strategy to transform waste into clean energy and water recovery, the efficiency of the AD process is reduced by the presence of recalcitrant materials, chemicals, and toxic contents. This study aims to […]

• The Nordic biogas model : Conceptualization, societal effects, and policy recommendations
  Because biogas systems may take many forms, utilizing different feedstock and finding different end uses for the biogas, it is becomes difficult to produce explanations, inferences, and conclusions about biogas systems in general, which is why concepts for specific types of biogas systems are needed. This paper introduces the concept of the Nordic biogas model, […]

• Boosting manure biogas production with the application of pretreatments: A meta-analysis
  Anaerobic digestion (AD) is a versatile manure management approach that can combine waste treatment, energy generation and nutrient recovery, thus playing a central role in circular economy. The AD process is highly influenced by manure composition which, depending on the source, may contain high loads recalcitrant materials (e.g., lignocellulosic and fibers) or lead to the […]

• Serial anaerobic digestion improves protein degradation and biogas production from mixed food waste
  Optimization of the biogas generation process is important to achieve efficient degradation and high methane yield, and to reduce methane emissions from the digestate. In this study, serial digester systems with two or three biogas reactors were compared with a single reactor, with the aim of improving degree of degradation and methane yield from food […]

• Influence of cysteine, serine, sulfate, and sulfide on anaerobic conversion of unsaturated long-chain fatty acid, oleate, to methane
  This study aims to elucidate the role of sulfide and its precursors in anaerobic digestion (i.e., cysteine, representing sulfur-containing amino acids, and sulfate) on microbial oleate conversion to methane. Serine, with a similar structure to cysteine but with a hydroxyl group instead of a thiol, was included as a control to assess potential effects on […]

• Identifying targets for increased biogasproduction through chemical and organicmatter characterization of digestate from full‑scale biogas plants : what remains and why?
  Background: This study examines the destiny of macromolecules in different full-scale biogas processes. From previousstudies it is clear that the residual organic matter in outgoing digestates can have significant biogas potential,but the factors dictating the size and composition of this residual fraction and how they correlate with the residualmethane potential (RMP) are not fully understood.

• Viscosity dynamics during anaerobic digestion of pulp and paper mill fibre sludge – the dependency on extracellular polymeric substances and soluble microbial products
  Increased viscosity and the presence of extracellular polymeric substances (EPS) and soluble microbial products (SMP) are important factors that may negatively affect wastewater treatment processes, e.g. foaming, inefficient mixing or poor dewatering. Many industries, including the pulp and paper industry, are running their production processes at shifting conditions, leading to large variations in wastewater composition […]
