Co-digestion of polylactide and kitchen garbage in hyperthermophilic and thermophilic continuous anaerobic process.

Inhibition of Thermophilic Anaerobic Digestion of Waste Food by Long Chain Fatty Acids and Propionate

Influence of kitchen biowaste addition on the effectiveness of animal manure digestion in continuous condition

The aim of the research was to establish the influence of kitchen biowaste as a co-substrate on the effectiveness and stability of animal faeces (pig manure) anaerobic digestion for biogas production, conducted in mesophilic conditions. Digestion process was conducted for manure as well as mixtures containing 10% of kitchen biowaste and 90% of manure. The proportion of substrates in the co-dige...

Modeling and Removal of Hydrogen Sulfide from Biogas Produced by Anaerobic Digestion

Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...

Effect of Physical and Chemical Operating Parameters on Anaerobic Digestion of Manure and Biogas Production: A Review

Introduction: The need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. On the basis of environmental and economic considerations, these materials require treatment and management. Anaerobic digestion and creation of biogas are the most effective methods of waste management. Several parameters affect the anaerobic digestion of ...

Analysis of mesophilic and thermophilic anaerobic digestion process applied to pressed biowaste during transient/stressed conditions and co-digestion with waste active sludge

The anaerobic digestion and co-digestion with waste activated sludge of liquid pressed biowaste from kerbside collection was studied both in mesophilic and thermophilic conditions. The research focused on the aspects related to a comparison between mesophilic and thermophilic conditions, also considering the processes stability during “non steady state” conditions and in specific perturbation i...
