This article aims to present the results of research on anaerobic digestion (AD) waste wafers (WF-control) and co-substrate system—waste cheese (WFC-control), combined with digested sewage sludge. The aim this study was assess physicochemical parameters diatomaceous earth/peat (DEP; 3:1) carrier material verify its impact enzymatic activity process performance. experiment conducted in a laborat...

Abstract In a net-zero emissions scenario, secure supply of electricity involves renewable generators that can flexibly increase their production when needed. Currently, generation from biogas in the water industry is most commonly at steady level, given anaerobic digestion (AD) traditionally operated state. This research demonstrated different scales demand-driven AD sewage sludge feasible. Pe...

Abstract As energy systems transition toward renewable resources, anaerobic digestion (AD) is actually receiving growing attention. AD relies on biochemical methane potential (BMP) tests to determine the of by-products carbonious nature. This investigation aims understand how an oxidative treatment, like Fenton reaction, influences BMP, starting from solid residues olive oil production, coming ...

Anaerobic digestion (AD) is one of the most widely used processes to stabilize waste sewage sludge and produce biogas as renewable energy. This study investigated effects Fe3O4 NPs at different concentrations (0,100 300 mg/L) on AD. 100mg/L could increase gas production by 21.9% reach highest methane content 66.75%. In addition, 100 mg/L kept pH an appropriate level. Scanning electron microscop...

This study evaluates the economic cost and sustainability of treating residual municipal solid waste (MSW) through five management scenarios. In baseline scenario (Bsc), all was managed landfilling, while in 1 (Sc1) treated by incineration. Sc2 employed anaerobic digestion (AD) for food Sc3 AD waste, incineration combustible plastic wastes, landfilling. Sc4 using AD, incineration, recycling was...

The management of anaerobic digestate is important to realize the value waste and enhance whole system sustainability digestion. In this study, phosphorus treatment dirty irrigation water by biochar samples derived from digestion were investigated. biochars further activated steam activation with different duration time KOH introducing ratios; textural properties optimized after aspect characte...

The use of sugar beet in anaerobic digestion (AD) during biogas production can lead to process upsets such as excessive foaming in fermenters. In the present study, foam formation in sugar beet-fed digestates was studied in foaming tests. The increasing disintegration grade of sugar beet was observed to have a promoting effect on foaming in the digestate but did not affect the biogas yield. Che...

The recycling of organic wastes is required from the viewpoint of environmental issues. Sewage sludge makes up about 30% of the organic wastes in Japan, and at present, the ratio is increasing (Study group on bio-waste recycling, 1999); therefore, it is important to treat and utilize the sewage sludge. Conventional treatment methods such as land filling and ocean dumping have been regulated to ...

The anaerobic digestion (AD) of biomass is a green technology with known environmental benefits for biogas generation. yield from existing substrates and the biodegradability biomasses can be improved by conventional or novel enhancement techniques, such as addition iron-based nanoparticles (NPs). In this study, effect different concentrations Fe2O3-based NPs on AD brown macroalga Sargassum spp...

The effects of antimicrobial chlortetracycline (CTC) on the anaerobic digestion (AD) of swine manure slurry using anaerobic sequencing batch reactors (ASBRs) was investigated. Reactors were loaded with manure collected from pigs receiving CTC and no-antimicrobial amended diets at 2.5 g/L/d. The slurry was intermittently fed to four 9.5L lab-scale anaerobic sequencing batch reactors, two with no...
