The depletion of fossil fuels and increasing demand for energy are encountered by
generating renewable biogas. Anaerobic digestion (AD) produces not only biogas, also …

Spent grain is the solid fraction remaining after wort removal. It is nutritionally rich,
composed of fibers—mainly hemicellulose, cellulose, and lignin—proteins, lipids, vitamins …

Biogas, a renewable energy source produced by the anaerobic digestion of organic matter,
can reduce greenhouse gas emissions. The purification and hydrogen conversion of biogas …

The impact of Iron oxide nanoparticles (IO-NPs) and IO-NPs doped granular activated
carbon (GAC) at three concentration levels of 0.16 g/L, 0.32 g/L and 0.48 g/L for IO-NPs and …

The valorisation of whiskey by-products was assessed and compared in three anaerobic
digestion systems. The systems produced similar methane yields, which could satisfy up to …

Closed-loop systems enable circular economy systems and applications in the food and
beverage sector to enhance decarbonisation. Whiskey distillation by-products are amenable …

Abstract Monitoring parameters like Oxidation-Reduction Potential (ORP) is crucial for the
intensification of the (H 2) production via Dark Fermentation (DF). This study examines the …

Traditionally, digestate is considered a waste, which is used as fertiliser in the agriculture
industry. Recent studies focus on increasing the profitability of digestate by extracting …

Abstract Ex-situ biomethanation (CO 2+ 4H 2→ CH 4+ 2H 2 O) can simultaneously achieve
renewable electricity storage and CO 2 valorisation. However, fluctuations in variable …

Biomethanation of carbohydrates (eg, lignocellulosic biomass) and lipids (eg, waste oils)
has been well studied. However, investigations on the biomethanation of protein-rich …
