The aim of the research was to establish the influence of kitchen biowaste as a co-substrate on the effectiveness and stability of animal faeces (pig manure) anaerobic digestion for biogas production, conducted in mesophilic conditions. Digestion process was conducted for manure as well as mixtures containing 10% of kitchen biowaste and 90% of manure. The proportion of substrates in the co-dige...

Chicken manure and pig fat are found abundantly around the globe, there is a challenge to get rid of them. This waste has considerable energy potential be recovered into fuel, but extracting this from some by-products, especially fat, isn’t an easy task. When anaerobic digestion technology stepped level co-digestion, utilisation hardly degradable became feasible. Our research was conducted on c...

The biomethane potential and biodegradability of an array of substrates with highly heterogeneous characteristics, including mono- and co-digestion samples with dairy manure, was determined using the biochemical methane potential (BMP) assay. In addition, the ability of two theoretical methods to estimate the biomethane potential of substrates and the influence of biodegradability was evaluated...

Co-digestion of dairy manure with off-farmwaste has become a common practice on US farms, however, little data at a commercial-scale is present within the literature. In response, a mesophilic, mixed plug-flow reactor co-digesting 16.36% v/v food processing substrates with dairy manure, was monitored for its performance and substrate effects. Co-digestion, as compared to substrate or manure-onl...

This paper investigates anaerobic co-digestion of pig manure and algae (Scenedesmus sp.) with and without extraction of intracellular algal co-products, with views towards the development of a biorefinery concept for lipid, protein and/or biogas production. Protein and/or lipids were extracted from Scenedesmus sp. using free nitrous acid pre-treatments and solvent-based Soxhlet extraction, resp...

Cattle slurry and card packaging were used to improve the operational stability of food waste digestion, with the aim of reducing digestate total ammoniacal nitrogen concentrations compared to food waste only. Use of cattle slurry could have major environmental benefits through reducing greenhouse gas emissions associated with current management practices; whilst card packaging is closely linke...

As the core technology of decentralised urban resource recovery system, the objective of this study was to evaluate the feasibility of anaerobic co-digestion of faeces (brown-water, BW) and foodwaste (FW). Batch assay indicated that anaerobic co-digestion (BW+FW) showed higher methane yield (0.540.59 LCH4/gVSadded) than BW and FW alone. Anaerobic co-digestion was subsequently performed in a me...

The potential of mesophilic anaerobic digestion for the treatment of fats of different origin through co-digestion with the organic fraction of municipal solid wastes (OFMSW) has been evaluated. Co-digestion process was conducted in a pilot plant working in semi-continuous regime in the mesophilic range (37 ◦C) and the hydraulic retention time (HRT) was 17 days. During the start-up period the d...

plug-flow digesters with periodic loading mechanism are more enthusiastic than fully mechanized digestion plants for the majority of small or medium scale farms according to the costs and operational complexities. a dual-compartment plug-flow reactor equipped with a passive heating system was designed and experimentally operated by purpose of demonstrating a simple and low cost technology for ...

Tobacco is widely planted across the world especially in China, which means that a large amount of tobacco waste needs to be treated. This study investigated the biogas fermentation of tobacco stalks co-digested with different biomass feedstocks and the inactivation of Tobacco mosaic virus (TMV), Cucumber mosaic virus (CMV) by anaerobic digestion. Results showed that the maximum methane yield o...
