Anaerobic co-digestion of organic wastes
Reviews in Environmental Science and Bio/Technology, 2012Over the last years anaerobic digestion has been successfully established as technology to treat organic wastes. The perspective of turning, through a low-cost process, organic wastes into biogas, a source of renewable energy and profit, has certainly increased the interest around this technology and has required several studies aimed to develop ...

Control strategy for maximum anaerobic co-digestion performance
Water Research, 2015A control strategy for optimising the performance of anaerobic co-digestion in terms of methane productivity, digestate quality and process stability is presented. A linear programming approach is adopted to calculate the feeding of multiple substrates for maximum methane productivity, subjected to restrictions based on experimental and heuristic ...

Batch anaerobic co-digestion of proteins and carbohydrates
Bioresource Technology, 2012Batch anaerobic studies were conducted using five mixtures (M1-M5) of bovine serum albumin (BSA) and starch. The results showed that co-digestion of BSA and starch had a positive impact on the methane production. The highest methane production of 288 mL, the highest methane yield of 360 mL CH(4)/g COD(added), and the highest maximum methane production ...

Semi-Continuous Anaerobic Co-Digestion of Agro-Wastes
Environmental Technology, 2002Anaerobic digestion is a well established process for treating many types of organic waste, both solid and liquid. As such, the digestion of cattle slurries and of a range of agricultural wastes has been evaluated and has been successful. Previous batch studies have shown that multi-component mixtures of agro-wastes can be digested successfully ...

Anaerobic co-digestion of sewage sludge and food waste
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2016Anaerobic co-digestion of organic matter improves digester operating characteristics and its performance. In the present work, food waste was collected from the institute cafeteria. Two types of sludge (before centrifuge and after centrifuge) were collected from the fluidised bed reactor of the institute treating sewage wastewater.

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 ...
