Many operating parameters, individually or together, may influence the performance of anaerobic digestion towards biogas or digestate yield and quality maximization. The most preferred method of optimizing an anaerobic ...

In August 2019, a new bus fleet of 36 electric and 58 hybrid buses were implemented in Trondheim, Norway. This paper examines the carbon footprint of electrified city buses, by addressing the achieved and potential reduction ...

Photosynthetic fluorescence emission spectra measurement at the temperature of 77 K (–196°C) is an often-used technique in photosynthesis research. At low temperature, biochemical and physiological processes that modulate ...

During the process of converting the organic matter into methane, many volatile fatty acids (VFAs) are produced during acidogenesis and acetogenesis phases of the process. The main VFAs of interest are acetic acid, butyric ...

Cyanobacteria require large quantities of iron to maintain their photosynthetic machinery; however, in most environments iron is present in the form of insoluble iron oxides. Whether cyanobacteria can utilize these sources ...

Et denitrifiseringsfilter kan ansees som et lite bærekraftig alternativ til vannbehandling i landbaserte fiskeoppdrettsanlegg siden det ikke tar vare på organiske nitrogenforbindelser som er verdifulle i for eksempel ...

Biogas, as derived from the anaerobic digestion process, offers a versatile possibility of renewable and sustainable energy usage. When enriched, upgraded biogas can yield high levels of biomethane, allowing its use as an ...

Biogas production is becoming significantly viable as an energy source for replacing fossil‐based fuels. The further development of the biogas production process could lead to significant improvements in its potential. ...

With the observed global intensification of the agricultural sector, slurry management has now become a severe problem causing a large amount of pollution due to industrial fertilizers. It is imperative that techniques are ...
