1. Abiotic and biotic methane dynamics in relation to the origin of life
Abstract : Methane (CH4) plays an important role in regulating Earth’s climate. Its atmospheric concentrations are related to both biotic and abiotic processes. The biotic one can be formed either by chemoautotrophic or heterotrophic pathways by methanogens. READ MORE

2. Methane production in dairy cows : individual cow variability in methane production
Abstract : Enteric methane (CH4) emissions vary between individual cows, and this variation is attributed to both animal and dietary factors. In addition, measurement technique of in vivo CH4 emissions from individual animals still represents a major challenge for successful emissions mitigation strategies. READ MORE

3. Predicting methane production in dairy cows
Abstract : Methane is a potent greenhouse gas, to which enteric fermentation from ruminants contributes significantly. Reliable and accurate predictions of methane (CH₄) production from dairy cows would be of interest to develop mitigation strategies and for national inventories. READ MORE

4. Methane and Volatile Fatty Acids Production from Toxic Substrate
Abstract : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. READ MORE

5. Sludge from pulp and paper mills for biogas production : Strategies to improve energy performance in wastewater treatment and sludge management
Abstract : The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills combines sedimentation, biological treatment, chemical precipitation, flotation and anaerobic treatment, and the specific combination of techniques is determined by the local conditions.
