“…At higher ozone doses (up to 510 mg L −1 ) an increase in filament transparency accompanied by the release of intracellular organic material was observed; these cellular material subsequently formed clusters (Akao et al, 2019). Similar effects were observed in the ozonation of mixed microalgae cultures for the production of methane through anaerobic digestion (Cardeña et al, 2017). At optimal ozonation pretreatment conditions a 66% increase in the methane yield was obtained.…”

“…Other chemical methods are the oxidative pretreatments (H 2 O 2 , O 3 FeCl 3 ), which are utilized to solubilize lignin and hemicellulose to increase the hydrolysis of cellulose (Monlau et al 2013b). The ozone method particularly has shown good results in the treatment of different types of biomass like microalgae biomass, where the methane yield was increased up to 66% with respect to biomass without pretreatment (Cardeña et al 2017). These physical and chemical methods may require expensive and special equipment or high energy input and may produce certain inhibitors [such as 5-hydroxymethylfurfural (HMF)] that could have a negative effect on subsequent process fermentation (Taniguchi et al 2005).…”

The present work summarizes different sources of biomass used as raw material for the production of biogas, focusing mainly on the use of plants that do not compete with the food supply. Biogas obtained from edible plants entails a developed technology and good yield of methane production; however, its use may not be sustainable. Biomass from agricultural waste is a cheap option, but in general, with lower methane yields than those obtained from edible plants. On the other hand, the use of algae or aquatic plants promises to be an efficient and sustainable option with high yields of methane produced, but it necessary to overcome the existing technological barriers. Moreover, these last raw materials have the additional advantage that they can be obtained from wastewater treatment and, therefore, they could be applied to the concept of biorefinery. An estimation of methane yield per hectare per year of the some types of biomass and operational conditions employed is presented as well. In addition, different strategies to improve the yield of biogas, such as physical, chemical, and biological pretreatments, are presented. Other alternatives for enhanced the biogas production such as bioaugmentation and biohythane are showed and finally perspectives are mentioned.

“…Cardeña et al (2017) demonstrated that ozonation enhanced the accessibility of certain microalgae which have structural and physical barrier to biodegradation, allowing, at the end,their biodegradability. Furthermore, both complexity and accessibility have not yet been considered together in any existing indicator.…”

Organic wastes are potential sources of both energy as well as crop production fertilizers. Correlations and models, involving organic matter characterization, have been previously described by several authors although there is still a lack in knowledge on the potential of simultaneous predictions of methane and organic fertilizer quality to optimize the wastes treatments. A methodology combining chemical accessibility and fluorescence spectroscopy was used to characterize 82 different organic wastes. Characterization data were compared with the biochemical methane potential (BMP), and with the biodegradable organic carbon obtained by soil incubation (C_bio). High correlations values were observed (R of 0.818 for BMP and 0.845 for C_bio). Model coefficients highlighted the differences and similarities between anaerobic and aerobic soil biodegradation, suggesting that anaerobic recalcitrant molecules could enhance soil fertility. This is a first step in the development of a tool for optimising both types of valorisation according to agrosystem needs and constraints.
