Anaerobic co-digestion of urban and rural wastes
Renewable Energy, 1999Abstract So far the technology of anaerobic digestion has not been able to meet the predicted expectation to its potential. Many factors have been influencing this but a generally trend has been that the biogas plants constructed have had problems of both technical and financial art even they as a rule have been subsidised with close to 50 ...

Anaerobic Co-Digestion of Dairy Manure and Glycerin
2008 Providence, Rhode Island, June 29 - July 2, 2008, 2008Co-digestion of dairy manure and glycerin was investigated as a strategy for improving the performance and economics of a dairy manure digester and also producing energy from glycerin, a byproduct of biodiesel production. The digestibility of dairy manure, glycerin and their mixtures were studied using batch anaerobic digestion experiments.

Anaerobic co-digestion of sewage sludge with OFMSW
Gjornâl Furlan des Siencis, 2011Anaerobic co-digestion of sewage sludge with Organic Fraction of Municipal Solid Waste (OFMSW) appears to be an interesting solution to increase the biogas production of WWTP (WasteWater Treatment Plant) under-loaded digesters. In this study developed by the Department of Chemistry, Physics and Environment of Udine University, the co-digestion process ...

Water-energy nexus: Anaerobic co-digestion with elephant grass hydrolyzate
Journal of Environmental Management, 2016The anaerobic co-digestion process in a continuous stirred-tank reactor (CSTR) was carried out under mesophilic conditions (37 ± 0.2 °C). All the trials were performed at a hydraulic retention time (HRT) of 15 days and the AD reactor was daily fed with a mixture of sewage sludge (SS) and elephant grass hydrolyzate (EGH).

Optimization of Anaerobic Co-digestion of Strawberry and Fish Waste
Applied Biochemistry and Biotechnology, 2014Anaerobic co-digestion of agri-food waste is a promising management alternative. Its implementation, however, requires evaluating the proportion in which waste should be mixed to optimize their centralized treatment. The combined treatment of strawberry extrudate and fish waste, which are widely generated in Mediterranean areas, was optimized ...

Generalised modelling approach for anaerobic co-digestion of fermentable substrates
Bioresource Technology, 2013A general methodology to implement fermentable soluble substrates in the IWA Anaerobic Digestion Model No. 1 (ADM1) that extends its application to anaerobic co-digestion of multiple substrates is presented. The approach considers the fermentation of new soluble substrates, not originally described in ADM1, as channelled through mass- and electron ...

Thermophilic anaerobic co-digestion of poultry litter and thin stillage
Bioresource Technology, 2013The purpose of this study was to test whether the performance of a thermophilic CSTR digester that has been stabilized on poultry litter will be enhanced or diminished by the addition of thin stillage as co-substrate. Replicate laboratory digesters, derived from a stable pilot-scale digester, were operated with increasing ratios (w/w) of thin stillage ...

Anaerobic co-digestion of different wastes in a UASB reactor
Waste Management, 2018Anaerobic co-digestion has made a greater impact on the biogas production from mixing different type of waste. In this research, sewage sludge (SS) and cow manure (CM), was used as a primary waste along with kitchen waste (KW), yard waste (YW), floral waste (FW) and dairy wastewater (DWW) as co-substrate for anaerobic digestion.

The anaerobic co-digestion of food waste and cattle manure
Bioresource Technology, 2013This study assessed the anaerobic co-digestion of food waste and cattle manure, in order to identify the key parameters that determine the biogas and methane yield. Results of both batch and semi-continuous tests indicated that the total methane production is enhanced in co-digestion, with an optimum food waste (FM) to cattle manure (CM) ratio of 2. At

Anaerobic batch co-digestion of sisal pulp and fish wastes
Bioresource Technology, 2004Co-digestion of various wastes has been shown to improve the digestibility of the materials and biogas yield. Batchwise digestion of sisal pulp and fish waste was studied both with the wastes separately and with mixtures in various proportions. While the highest methane yields from sisal pulp and fish waste alone were 0.32 and 0.39 m3 CH4/kg volatile ...
