LCA analysis of food waste co-digestion
Science of The Total Environment, 2020The i-REXFO LIFE project designs an innovative business model with the objective of reducing significantly the amount of landfilled food waste. Given the availability of supermarket food waste in the Umbria region (Italy), the logistics is optimized using a Vehicle Routing Problem Solver, mass and energy balances of the biogas plant are partly ...

Probiotic effects of anaerobic co-digestion substrates
Environmental Technology, 2018Manure 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 ...

Renewable Energy, 2021
Abstract The recalcitrant structure of Cannabis ruderalis straw (CRS) inhibits the recovery of bioenergy from its anaerobic digestion. This paper attempted to estimate the digestive performance of CRS mono-digestion and its co-digestion with blackwater (BW) by hydrothermal pretreatment at different temperature (120, 140 and 160 °C).

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 ...

GISCOD: General Integrated Solid Waste Co-Digestion model
Water Research, 2009This paper views waste as a resource and anaerobic digestion (AD) as an established biological process for waste treatment, methane production and energy generation. A powerful simulation tool was developed for the optimization and the assessment of co-digestion of any combination of solid waste streams.

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 ...

Batch co-digestion of multi-component agro-wastes
Bioresource Technology, 2001In certain parts of the developing world conventional energy supplies such as electricity, gas, coal and petroleum by-products are either unavailable, too capital intensive to install, are unjustifiable due to low population densities in some semi-arid regions, or are simply unaffordable to the target population.

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 ...

Co-digestion of agricultural and industrial wastes
Chemical Papers, 2010AbstractThe efficiency of anaerobic digestion process is dependent on the type and composition of the material to be digested. This work examines the co-digestion of corn silage, beet pulp silage, carrot residues, and cheese whey in different configurations together with a glycerin fraction — the waste product of transestrification of oils (biodiesel ...
