“…Möller and Müller [74] reported 2.2% N, 0.4% P and 0.9% K in pig slurry digestate derived from German biogas plants, while some solid digestates contained 51-61% mineral N that suggested their best use would be as fertilizer [72]. Moreover, digestate application could reduce the risks of P runoff as labile-P fractions are significantly decreased in anaerobic digestion [75]. Few studies have addressed the fertilizer value of anaerobically produced digestate.…”

“…Based on the above discussion, we also realize that agronomic efficiency of animal-derived fertilizers is highly dependent on its N availability. In contrast, various studies considered animal waste as a source of P in sustainable agriculture [42,75,106]. Judicious use of animal manures maximizes economic returns increasing crop yield per unit of fertilizer applied [107].…”

Healthy soils are essential for progressive agronomic activities. Organic fertilization positively affects agro-ecosystems by stimulating plant growth, enhancing crop productivity and fruit quality and improving soil fertility. Soil health and food security are the key elements of Organic Agriculture 3.0. Landfilling and/or open-dumping of animal wastes produced from slaughtering cause environmental pollution by releasing toxic substances, leachate and greenhouse gases. Direct application of animal carcasses to agricultural fields can adversely affect soil microbiota. Effective waste management technologies such as thermal drying, composting, vermicomposting and anaerobic digestion transform animal wastes, making them suitable for soil application by supplying soil high in organic carbon and total nitrogen. Recent agronomic practices applied recycled animal wastes as organic fertilizer in crop production. However, plants may not survive at a high fertilization rate due to the presence of labile carbon fraction in animal wastes. Therefore, dose calculation and determination of fertilizer application frequency are crucial for agronomists. Long-term animal waste-derived organic supplementation promotes copiotrophic microbial abundance due to enhanced substrate affinity, provides micronutrients to soils and protects crops from soil-borne pathogens owing to formation of plant-beneficial microbial consortia. Animal waste-derived organically fertilized soils possess higher urease and acid phosphatase activities. Furthermore, waste to fertilizer conversion is a low-energy requiring process that promotes circular bio-economy. Thus, considering the promotion of soil fertility, microbial abundance, disease protection and economic considerations application of animal-waste-derived organic fertilizer should be the mainstay for sustainable agriculture.

“…From the perspective of engineering applications, this study may provide an evidencebased recommendation for optimising the operations of AD process in order to improve the CH4 production efficiency. The current applied AD plants are normally operated under a hydraulic retention time of 20-30 days for manures (Li et al, 2020) and 40-50 days for lignocellulosic biomass (Guo et al, 2018;Xu et al, 2020), respectively.…”

Humic acid (HA), a byproduct formed during the biological conversion of organic matter into biogas in the anaerobic digestion (AD) process, contains complex structures and redox functions. However, the evolution mechanism of HA and its interaction with CH4 production during the AD process have not been fully explored, particularly with respect to various substrates and temperature conditions. In this study, we investigated the evolutionary dynamics of the structure and function of genuine HA that naturally formed in the AD processes of chicken manure and corn stover under mesophilic (37 °C) and thermophilic (55 °C) conditions. The results demonstrated that the HA evolution mechanisms in AD of chicken manure and corn stover have different pathways. The AD of core stover showed higher degree of aromaticity (41.2-66.7% and 45.3-68.4% for mesophilic and thermophilic respectively) and humification index (1.5-4.2 and 2.8-4.5 for mesophilic and thermophilic respectively) than those (28.3-45.3% and 30.2-54.5% of aromaticity and 0.6-1.2 and 1.3-3.7 of humification index) in AD of chicken manure.

“…Firstly, P from manure is recovered by using manure directly as a fertilizer. However, due to high concentration of nutrients, nitrogen and phosphates can leach into the ground water together with high contents of antibiotics, which causes water pollution and leads to a spread of antibiotic resistant genes or bacteria into the environment [51–53]. Efforts to recover P from animal manures without causing over‐fertilization and negative environmental effects can be made with the help of bacteria, fungi and algae.…”

Phosphorus (P) is a non‐renewable resource and is on the European Union's list of critical raw materials. It is predicted that the P consumption peak will occur in the next 10 to 20 years. Therefore, there is an urgent need to find accessible sources in the immediate environment, such as soil, and to use alternative resources of P such as waste streams. While enormous progress has been made in chemical P recovery technologies, most biological technologies for P recovery are still in the developmental stage and are not reaching industrial application. Nevertheless, biological P recovery could offer good solutions as these technologies can return P to the human P cycle in an environmentally friendly way. This mini‐review provides an overview of the latest approaches to make P available in soil and to recover P from plant residues, animal and human waste streams by exploiting the universal trait of P accumulation and P turnover in microorganisms and plants.
