Anaerobic co-digestion: Current status and perspectives

Bioresource Technology, 2021
Anaerobic digestion is a long-established technology for the valorization of diverse organic wastes with concomitant generation of valuable resources. However, mono-digestion (i.e., anaerobic digestion using one feedstock) suffers from challenges associated with feedstock characteristics. Co-digestion using multiple feedstocks provides the potential to

Probiotic effects of anaerobic co-digestion substrates

Environmental Technology, 2018
Manure is often added to stabilise anaerobic digesters especially when co-digesting high-energy substrates such as whey. While different researchers have attributed its beneficial effect to various components including alkalinity, nutrients or trace elements this research instead aimed to determine whether microorganisms, such as lactic acid bacteria ...

Anaerobic co-digestion of organic wastes

Reviews in Environmental Science and Bio/Technology, 2012
Over 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, 2015
A 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, 2012
Batch 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, 2002
Anaerobic 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, 2016
Anaerobic 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.
