Approaches for adding value to anaerobically digested dairy fiber
(2017)
One of the consequences of the increase of large dairy concentrated feeding operations (CAFOs) is the abundance of dairy manure that needs to be disposed of or used in some way. CAFOs can become bio-refineries, harnessing ...
Addition of lipolytic enzyme in anaerobic co-digestion of swine manure and inclusion levels of waste vegetable oil
(2014)
Studies that aim the reusing of agro-industrial wastes have become very important due to the high production of this sector and environmental preservation. The objective of this work was to evaluate the performance of ...
Estabilización de temperatura en un digestor anaerobio tipo U.A.S.B alimentado con residuos bovinos y lodos
(Ediciones Universidad de América, 2016-11-24)
Esta investigación evaluó la estabilización de la temperatura en la digestión anaerobia del residuo bovino. El objetivo fue desarrollar una estrategia con base en la temperatura para agilizar la producción de biogás y/o ...
Performance of semi-continuous anaerobic co-digestion of poultry manure with fruit and vegetable waste and analysis of digestate quality: A bench scale study
(2018)
Poultry manure (PM) can contain ammonium and ammonia nitrogen, which may inhibit the anaerobic process. The aim of this work was to evaluate the performance of anaerobic digestion of PM co-digested with fruit and vegetable ...
Codigestão anaeróbia de dejetos de suínos e níveis de inclusão de óleo de descarte
(Soc Brasil Engenharia Agricola, 2015-01-01)
Swine manure and lipid residue co-digestion has been widely explored with improvements in substrate degradation, digestion and consequently biogas yield. Thus, we evaluated performance of digesters supplied with swine ...
Anaerobic co-digestion of sweet potato and dairy cattle manure: A technical and economic evaluation for energy and biofertilizer production
(2019-07-20)
Energy from biomass is essential for sustainable agricultural development. The generation of biogas and bio-fertilizer from the anaerobic co-digestion is fundamental in mitigating environmental problems and in the local ...
Performance of the anaerobic co-digestion of pig manure with the inclusion of crude glycerine
(Univ Federal Ceara, Dept Geol, 2016-10-01)
The aim of this study was to evaluate the performance of the anaerobic co-digestion of pig manure associated with increasing doses of crude glycerine, adopting different periods of hydraulic retention time (HRT). A completely ...
Laying hen manure in anaerobic Co-Digestion with glycerin containing different glycerol and impurity levels
(Elsevier B.V., 2019-04-01)
Biodiesel has arisen as a promising option of renewable fuel to minimize the impacts caused by fossil fuels. However, its production process generates high amounts of crude glycerin as a residue, which is considered ...
Co-digestion of swine excreta associated with increasing levels of crude glycerin
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2016-03-01)
The objective of this research was to evaluate the performance of anaerobic co-digestion of swine excreta associated with increasing doses of crude glycerin and different hydraulic retention times (HRT). A completely ...
Responses of anaerobic microorganisms to different culture conditions and corresponding effects on biogas production and solid digestate quality
(2016)
Microbial communities of anaerobic digestion have been intensively investigated in the past decades. Majority of these studies focused on correlating microbial diversity with biogas production. The relationship between ...
