Global demand for both clean energy carriers and agricultural nutrients continues to grow rapidly, alongside increasing quantities of waste globally, interlinked challenges that may be addressed with solutions. We report on the potential efficiency Greenhouse Gas (GHG) intensity several configurations a new, sustainability-driven ammonia (NH 3 ) production processes determine whether waste-base...

Abstact: The aim of the research project was to carry out the co-digestion of organic fraction of solid municipal waste in the form of source separated kitchen waste and sewage sludge. The influence of the kitchen waste as a co-substrate on the stability and efficiency of the process was determined. Mesophilic fermentation (36 ̊C) was conducted for sewage sludge as well as mixtures of sewage slu...

This study investigated the possibilities of improving methane yield production from, the anaerobic co-digestion of wheat straw (WS) and primary sludge (PS). The batch experiment was conducted under mesophilic conditions. Different mixtures of WS and PS depending on its C/N ratio were carried out to investigate the optimum C/N ratio for effective methane production. The cumulative methane yield...

Abstract Anaerobic co-digestion is widely adopted to enhance process efficacy by balancing the C/N ratio of feedstock while converting organic wastes biomethane. Goat manure (GM) and cotton gin trash (CGT) were anaerobically co-digested in triplicate batch bioreactors. The was optimized evaluated utilizing mathematical equations. liquid fraction digestate analyzed for nitrate phosphate. co-dige...

Usually, slaughterhouse wastewater has been considered as a single substrate whose anaerobic digestion can lead to inhibition problems and low biodegradability. However, the bovine slaughter process generates different streams with particular physicochemical characteristics: (SWW), offal (OWW) paunch (PWW). Therefore, this research aims assess co-digestion (AcoD) of SWW, OWW, PWW manure (BM) th...

Oilseed rape straw (ORS) is a kind of biorefractory waste widely existing in the rural area of China, which is highly suitable to mix with kitchen waste (KW) and duck droppings (DD) in two-phase anaerobic digestion (AD). This research introduced the importance of KW and DD addition to improve the biogas production and biodegradation of ORS. A set of comparative experiments were conducted on two...

The Wharton's Jelly (WJ) is an established source of mesenchymal stem cells (MSC). We compared 3 methods of extracting WJ-MSC from cryopreserved tissue and determined that enzymatic digestion of the WJ yielded the most viable MSC, compared to the explant and mechanical digestion methods. The enzymatically-released WJ-MSC conformed to the International Society for Cellular Therapy (ISCT) criteri...

Microbial pretreatments have been identified as a compatible and sustainable process with anaerobic digestion compared to energy-intensive physicochemical pretreatments. In this study, barley straw hay co-substrate was pretreated microaerobic straw-adapted microbial (BSAM) consortium prior digestion. The improved digestibility investigated through 16S rRNA gene sequencing, counts C:N ratios. BS...

In this study, the impact of thermal hydrolysis pretreatment (THP) on mono- and co-digestion thickened waste activated sludge (TWAS) food (FW) was carried out at temperatures 150, 170, 190, 210 °C volumetric ratios 90:10, 70:30, 50:50 in batch anaerobic tests. THP enhanced solubilization, reduced volatile suspended solids (VSS) particle size TWAS as temperature increased showing optimal improve...
