On-farm feedstocks such as grass silage and cattle slurry present recalcitrant characteristics
that can limit microbial conversion in biofuel production. Introducing a biochar supplement in …

The problematic anaerobic digestion (AD) of protein-rich substrates owing to their high
ammonia content continues to hinder optimum methanation despite their high potential for …

Our current industrial ammonia cycle is far from being sustainable–while intense energy is
required to produce ammonia–almost half of it ends up in wastewater treatment plants …

In this study, a lab-scale system integrated with up-flow anaerobic blanket reactor and partial
nitritation-anammox (UASB-PN/A) was conducted for the purpose of carbon-neutral removal …

Energy-efficient wastewater treatment units are imperative to achieve carbon neutrality and
a circular economy at the industrial scale. In the present study, pyrochar loading and …

Transmembrane chemical absorption (TMCS) is a promising technology to recover
ammonia from high-strength wastewater and sustainably produce fertilizers for agricultural …

Ammonia nitrogen, as an essential intermediate product during the process of anaerobic
fermentation, is an important indicator for analyzing the nitrogen nutrient level, the specific …

The present study employed biochar in three different particle sizes (< 2 mm, 2–5 mm,> 5
mm) to reduce the anaerobic recalcitrance of distillery wastewater in anaerobic bioreactors …

Full-scale thermal hydrolysis processes (THP) showed an increase in nutrients release and
formation of melanoidins, which are considered to negatively impact methanogenesis during …

Nanobubble water (NBW) or temperature-phased anaerobic digestion assisted by microbial
electrolysis cell (MEC-TPAD) can promote sludge hydrolysis and methanogenesis …
