The anaerobic digestion, AD, process presents a solution for sustainable waste management, greenhouse gas mitigation and energy production growing population needs requirements. Adopting biorefinery approach that utilises different feedstock may enhance support optimisation of the digestion process. Algae is promising could be used via Microalgal biomass rich in carbohydrates lipids; however, m...

The integration of hydrothermal carbonisation (HTC) and anaerobic digestion (AD) can overcome some the disadvantages thermal or biological processing alone. This study aims to investigate integrated HTC-AD across a range strategies HTC temperatures (150 °C, 200 °C 250 °C) improve energy conversion efficiency (ECE) grass, compared AD separation hydrochars (HCs) for combustion process waters (PWs...

This study tested the hypothesis that the easily degradable carbohydrates of the sugar beet silage (S) will improve the anaerobic digestion of grass silage (G) more profoundly compared to co-digestion of sugar beet silage with maize silage (M). M : S and G : S mixtures were tested in two continuous laboratory-scale AD experiments at volatile solid ratios of 1 : 0, 6 : 1, 3 : 1, and 1 : 3 at org...

The advantages of anaerobic digestion (AD) technology in organic solid waste treatment for bioenergy recovery are evidenced worldwide. Recently, more attention has been paid to on-site biogas research, as well biogenic CO2 sequestration from AD plant, promote “carbon neutral”. Single-phase and two-phase system can be incorporated with various bioconversion technologies through H2 mediated (in-s...

Anaerobic digestion (AD) can bring benefits in terms of effective management organic waste, recovery nutrients and energy recovery, is consistent with circular economy principles. AD has been promoted implemented worldwide, but at widely differing scales, influenced by the availability location feedstocks. In developing countries, feedstock arises from small- to medium-scale agriculture agro-pr...

The issue of ever-increasing amounts waste activated sludge (WAS) produced from biological wastewater treatment plants (WWTPs) is pointed out. WAS can be effectively reduced in the anaerobic digestion (AD) process, where methanogens break down organic matter and simultaneously produce biogas absence oxygen, mainly methane CO2. Biomethane then used gas turbines to electricity power a part WWTPs....

Anaerobic digestion (AD) is a treatment approach that mineralizes complex organic carbon into inorganic carbon in the form of biogas, diminishing odors/pathogens and stabilizing waste (US-EPA, 2008). Biogas can be used as a renewable energy, while AD also allows for reductions in methane (CH4) and overall greenhouse gas (GHG) release (US-EPA, 2011). As a result, there has been increasing intere...

The organic fraction of municipal solid waste (OFMSW) is recognized as a suitable substrate for the anaerobic digestion (AD) process and currently considered mature technology. A promising strategy to enhance biogas yield productivity co-digestion OFMSW with other biomass, such green (GW), mixture leaves, grass, woody materials originated from private yards public greenspace management. main li...

This is a pioneer study evaluating the methane (CH4) production potential from residues of integrated first (vinasse and filter cake) second (deacetylation pretreatment liquor straw) generation (1G2G) sugarcane biorefinery, providing fully chemical characterization them their relation with anaerobic digestion (AD) process. Small-scale assays provided fundamentals for basing co-digestion optimiz...

Bioplastics are increasingly replacing traditional plastics in many sectors, but the legislative and operative frameworks for their disposal remain unclear: they should be collected treated together with organic fraction of municipal solid waste (OFMSW), often do not biodegrade satisfactorily plants that treat OFMSW. This work focuses on a type cellulose diacetate employed eyewear industry to a...
