Kinetics of mesophilic anaerobic digestion of the organic fraction of municipal solid waste: Influence of initial total solid concentration

Bioconversion of Egypt's Agricultural Wastes into Biogas and Compost

“…Furthermore, agro-industrial wastes such as bagasse of magnitude 4.7×10 6 tons result from sugar cane. This bagasse is mostly used for heat/electricity generation in the sugar mills, but with poor efficiency and black smoke emissions.…”

“…The major result of applying the first scenario of AD bioconversion is converting an amount of 24.3×10 6 tons of Egypt's AWs into ≈ 12.757×10 9 m 3 of biogas and ≈ 9.7×10 6 tons of digestate, whereas by applying the second scenario of aerobic digestion, the same amount of AWs will be converted into 10.21×10 6 tons of compost. These two approaches can solve not only the problem of AW management but also contribute to minimizing the negative impacts on both environment and public health.…”

“…organic compost [5], and AD (biogas) technology, which is a promising treatment method applied worldwide to convert biomass into biogas and organic digestate [6]. The produced compost from composting and digestate from biogas techniques can be used as biofertilizers that can replace chemical fertilizers, minimizing environmental pollution and health damage, enhancing crop yield (in conjunction with reducing costs involved in consuming nitrogen fertilizers), and consequently increasing revenue for farmers [7].…”

Exploration of One-Factor Rsm to Optimize the Concentration of Organic Fraction of Municipal Solid Waste (OFMSW) for Biogas Production

“…On the other hand, as one of the driving forces of economic and social development, anaerobic digestion of OFMSW for the production of sustainable biofuel (such as biogas) as well as biofertilizer has become a growing world interest [1][2][3][4][5][6][7][8][9][10][11][12][13]. The initial concentration or solid content of the substrate in a bioreactor can significantly affect performance of the anaerobic digestion process [14][15][16][17][18][19]. In order to increase the efficiency of anaerobic digestion, it is necessary to understand the role of total solids content (substrate concentration) on the behaviour of the microbial communities involved in anaerobic digestion of organic matter in wet and dry technology [18].…”

Codigestão anaeróbia de resíduos orgânicos

“…Portanto, a digestão anaeróbia representa uma promissora alternativa tecnológica, pois propicia a redução da poluição ambiental, e, consequentemente, produz biogás e biofertilizantes. O tratamento anaeróbio de resíduos orgânicos não é tão difundido quanto o processo aeróbio, principalmente devido ao longo tempo necessário para alcançar a bioestabilização (FERNANDEZ et al, 2010). O processo anaeróbio é também sensível a elevadas concentrações de nitrogênio amoniacal, em especial quando existe a biodegradação anaeróbia dos componentes proteicos ricos em nitrogênio (FOUNTOULASKIS et al, 2008).…”
