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 ...

Mixture optimization of anaerobic co-digestion of tomato and cucumber waste
Environmental Technology, 2015Greenhouse cultivation has significantly increased the production of vegetables and reduced dependence on environmental conditions. In Mediterranean areas, vegetable crops are nowadays one of the most important sources of organic waste generation. Anaerobic digestion is among the methods used to treat this type of biodegradable waste.

Feasibility of anaerobic co-digestion of poultry blood with maize residues
Bioresource Technology, 2013The potential of anaerobic digestion for the treatment of poultry blood was evaluated in batch assays at laboratory scale and in a mesophilic semi-continuously fed digester. The biodegradability test performed on poultry blood waste showed a strong inhibition.

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 ...

Investigation on the anaerobic co-digestion of food waste with sewage sludge
Applied Microbiology and Biotechnology, 2017In this laboratory-scale investigation on the applicability of the co-digestion of food waste with sewage sludge, evaluated were the effects of the single-stage versus two-stage operating modes at the hydraulic retention time (HRT) of 15 days, and the impact of HRTs: 15 days vs. 25 days, on the single-stage operation.

Anaerobic digestion of glycerol and co-digestion of glycerol and pig manure
Journal of Environmental Management, 2012The potential of glycerol obtained from transesterification of waste cooking oil as a main carbon source for biogas production was investigated. The glycerol was highly contaminated with oils and fats and was pretreated with sulfuric acid. Using a carbon source of glucose as a control, we compared biogas production from the acid-treated glycerol in a ...

Utilisation of wastewater nutrients for microalgae growth for anaerobic co-digestion
Journal of Environmental Management, 2013The feasibility of growing microalgae in natural light using wastewater high in nutrients (N & P) for the production of more bioenergy was examined. The main retrofitting unit would be a photobioreactor for wastewater treatment plants (wwtp) having anaerobic digesters in close proximity. Theoretical microalgae production rates from different wastewater

Anaerobic co-digestion of septage and landfill leachate
Bioresource Technology, 1999Abstract This paper examines the operating parameters and treatment efficiency in digestion of septage with landfill leachate. Four lab-scale CSTR digesters were operated at 35 ± 1°C. Septage and leachate were mixed at the ratio of 1:0, 1:1, 2:1 and 3:1 on the basis of chemical oxygen demand (COD).

[Anaerobic co-digestion of corn stalk and vermicompost].
Huan jing ke xue= Huanjing kexue, 2011The characteristics of corn stalk digested alone at different total solid (TS) loading rates and co-digestion of various proportions of corn stalk and vermicompost were investigated by batch model at 35 degrees C +/- 1 degrees C. The organic loading rates (OLRs) studied were in the range of 1.2%-6.0% TS and increasing proportions of vermicompost from ...
