There is a great need to implement low-cost and user-friendly methods for further propagation of biogas technology in India. Environment unfriendly disposal of floral waste causes serious environmental pollution. Literature shows a limited research work regarding the anaerobic digestion of floral waste for biogas generation.  The present experimental work aims to propagate floral waste as a sus...

The synergistic and inhibitory interactions observed between Fibrobacter succinogenes A3c, Prevotella ruminicola H2b, and Ruminococcus flavefaciens B34b in the digestion of forage cellulose were studied in detail. Orchardgrass and alfalfa hays, both at two maturity stages, were used as substrates. Sequential inoculation procedures were developed whereby a second inoculation was made after the i...

This study investigated the potential benefit of co-digesting sewage sludge (SS) and settled/mixed fat, oil, grease (FOG) with BioAmp pretreatment, a bio-additive product, for utility. was found to increase soluble chemical oxygen demand (SCOD)/COD ratio FOG (from 4.19 4.49), consequently enhancing volatile solid (VS) reduction 75.9 84.8%). The SS co-digestion based on their actual daily produc...

The performance of a novel reverse membrane bioreactor (RMBR) with encased microorganisms for syngas bio-methanation as well as a co-digestion process of syngas and organic substances was examined. The sachets were placed in the reactors and examined in repeated batch mode. Different temperatures and short retention time were studied. The digesting sludge encased in the PVDF membranes was able ...

The co-digestion of two problematic and available wastes, namely Organic Fraction Municipal Solid Waste (OFMSW) and biological sludge, was carried out in this work. Biochemical Methane Potential (BMP) tests are a useful tool for determining the best substrate and co-digestion configurations, however there are some methodologies destined to save costs and time from this process by using the theo...

Working at thermophilic conditions instead of mesophilic, and also the addition of a co-substrate, are both the ways to intend to improve the anaerobic digestion of the source-collected organic fraction of municipal solid wastes (SC-OFMSW). Addition of sewage treatment plant fat, oil and grease wastes (STP-FOGW), that are nowadays sent to landfill, would represent an opportunity to recover a wa...

Anaerobic digestion of sewage sludge (SS) and co-digestion with cheese whey (CW) was evaluated in batch conditions under mesophilic and thermophilic regimens. Results indicated that the co-digestion can be successfully attained despite some inhibitory stages that may be initially present due to the accumulation of volatile fatty acids. Degradation of the mixture SS-CW followed a similar pattern...

Pig manure currently results in sizeable greenhouse gas emissions, during storage and spreading to land. Anaerobic digestion hydrothermal carbonisation could provide significant mitigation, as well generate renewable heat power (with anaerobic digestion), or a peat-like soil amendment product carbonisation). The mitigation potential associated with avoidance of pig the UK, EU, China, by product...

The present study aimed to investigate the in vitro starch digestion of cooked rice grain with added vegetable oils. Polished (400 g) was 500 mL ultrapure water only or one six types oils (cocoa butter [CB], coconut oil, corn oil [CO], olive [OO], palm and rapeseed [RO]), then frozen stored. reheated using a microwave used for texture analysis, gastro-small intestinal digestion, microstructure ...
