“…In addition to that, on storage conditions, a large percentage of this organic nitrogen of manure is converted to ammonia within a year [62]. Ammonia exists in two forms: gas state (NH 3 ) that can be lost to the atmosphere for greenhouse gas production or in an ionized state NH 4 + , which is water-soluble, this last state can be transformed by microorganisms to nitrate (nitrification process) [63,64]. Ammonia is considered the major problem in the anaerobic digestion of organic waste.…”

Background Animal husbandry is one of the agricultural activities that generates economic benefits for agriculture. We detected significant development of these activities in Morocco. Currently, it is stuck between the increase of organic waste polluting the farm environment and the energy needed to ensure the activities. Faced with this challenge, we determined all physical, chemical, and microbiological characteristics for livestock wastes most spread in Morocco. We evaluated also their ability to be used as bioresources for the anaerobic digestion and incineration ways for energy production to agricultural units. Methods We worked on four organic wastes (cow dung, horse manure, broiler droppings, and the excrement of laboratory mouse). The physical, chemical, and microbiological characteristics: moisture, total solids, volatile solids, organic carbon, nitrogen, ions and heavy metals, staphylococci, coliforms, yeasts and fungi and total aerobic mesophilic bacteria are determined by standard methods. The determination of lower heating value is performed with calorimetric bomb. The biogas production is determined by four batch types of digesters. All digesters are incubated at 35 ± 1 ℃ for 40 days. The volumes of biogas produced are corrected under standard pressure and temperature conditions. Results We noticed that the four agricultural wastes have a lower heating value closer to each other. When comparing the physicochemical composition of our wastes with that of Tanner’s theoretical waste, we have found that the valorization of these organic wastes by incineration is without energy and economic benefits. The microbiological content reflects the presence of a reservoir of pathogenic bacteria. On the other hand, the biogas potential shows that cow waste produces the largest amount of biogas. The co-digestion is necessary for horse manure, chicken manure, and excrement of laboratory mouse in order to increase their biogas potential. The mineral composition shows the possibility of using digestate of these wastes as an organic amendment to plants. Conclusions The comparison of the physicochemical and microbiological characteristics of the four organic wastes in Morocco reflects some important points. Firstly, there is an urgency to intervene to treat and valorize these wastes before putting them in the open air. Secondly, the incineration of this waste is inadequate from an energy point of view. In the third position, these wastes present a great ability to be used as feed substrates of farm digesters. Finally, the biogas potential and the mineral composition of these wastes demonstrates the ability to use them as bioresources capable of producing green energy and an organic amendment to Moroccan farms.

“…Three methods, namely, direct combustion, use in land as a fertilizer, and composting are employed for the disposal of poultry waste. AD of CM has many benefits such as digestate in stabilized form as a fertilizer, better sanitation near poultry farms, and reduced emissions of ammonia than direct land spreading and composting [35,36].…”

The control strategies adopted in formulation and anaerobic digestion (AD) process of chicken manure (CM) for the control and enhancement of biogas production are reviewed. The existing limitations and future challenges in the production of biogas from AD of CM are briefly discussed. The control strategy adopted for formulation is pretreatment of CM (physical, chemical, biological, and thermal) while strategies for AD include selection of optimal parameters (pH, C/N ratio, organic loading rate (OLR), and temperature), co‐AD with other substrates, and addition of supporting materials. The pretreatment of CM, selection of optimal parameters, Co‐AD of CM with other substrates, and addition of supporting materials overall enhance biogas and methane production due to increase of hydrolysis and C/N and decrease of ammonia inhibition, CO2 and H2S contents. The implementation of developed control strategies in continuous plants, development of new strategies, and use of supporting materials in combinations of two or three for better performance are the future challenges in the AD of CM. The control strategies had a significant impact on the efficient use of CM and improved biogas and methane production.

“…Biogas is enriched by removing unwanted gases (CO 2 , H 2 S and water vapor) to increase the calorific value, so that it is economical to compress and transport to longer places for distribution or move to other area for multifaceted applications [24][25][26]. Biogas production by AD is an established technology that allows farmers to generate more income from biomass waste and closing nutrient cycles [25,27]. These synergies can be extended even further if microalgal cultivation is added to produce algae-based bioproducts.…”

Biogas - Recent Advances and Integrated Approaches

Global environmental protection is of immediate concern and it can only be achieved by avoiding the use of fossil fuels. In addition, waste disposal and management could be made remunerative through the generation of renewable energy so that sustainable development is ensured. India is an agriculture-based country, and paddy residues such as rice straw and rice husk are the largest agricultural wastes in India. Currently, the common practice to dispose paddy residues is through field burning, but this has adverse effects on the air quality and consequently on people's health. However, utilization of lignocellulosic and non-food agricultural residues such as paddy residue for biogas generation by solid-stated anaerobic digestion (AD) is promising and this can substitute fossil fuels. Paddy residues for biogas production via AD has not been widely adopted because of its complex cell wall structure making it resistant to digestion by microbial attack. In addition, sequestration of carbon dioxide from biogas by algal biomass cultivated in an integrated algal bioreactor could be a promising option for biogas enrichment due to its unmatched advantages. This chapter presents the overview on utilization of non-edible residues for biogas production and its enrichment via algal biomass by means of circular bioeconomy.
