“…Maunuksela et al (2012), with the use of plant bioassays, tested the phytotoxicity of various biogas products in concentrations used in the field conditions, proving their suitability as fertilizers. Various treatment processes of biogas residues are available to ensure that the end products meet the requirements of environmental regulations (Adam et al, 2018). However, there is a need for long-term field experiments regarding heavy metal and organic pollutant build-up in soil and plant tissues.…”

“…Therefore, they can be used as a biofertilizer, recycling nutrients such as nitrogen, phosphorus and potassium back to agricultural soils (Abubaker, 2012) while improving soil quality (Nkoa, 2014). Furthermore, developing digestate treatment technologies have the potential to provide concentrated biofertilizers of high-value while allowing the recovery of the water contained in the liquid fraction of biogas residues and the reduction of transportation costs (Adam et al, 2018). Moreover, the on-farm anaerobic digestion of readily available organic resources can cover the demands of the farm in heat and power, while implementation on a global scale has the potential to reduce gross greenhouse gas emissions by 10% (Tsachidou et al, 2018).…”

To provide sufficient quantities of food and feed, farming systems have to overcome limiting factors such as the nutrient depletion of arable soils. Nitrogen being the main mineral element required for plant growth, has led to the extensive use of chemical fertilizers causing nitrogen pollution of the ecosystems. This field study investigates the use of biogas residues (BRs) as biofertilizers and their contribution to the mitigation of nitrate leaching in agricultural soils, while also demonstrating the polluting nature of chemical fertilizers. Nine different fertilization treatments classified in three schemes and two nitrogen doses were tested for three consecutive years on a grassland in the Walloon Region of Belgium. Residual soil mineral nitrogen, percentage contribution of treatments in residual nitrate and agronomic performance were assessed for each fertilization treatment. The results obtained showed significant differences on treatment and scheme level regarding nitrate accumulation in the soil, with chemical fertilizers posing the highest nitrate leaching risk. BRs did not cause nitrate accumulation in the soil, and were N rate and rainfall independent, while the chemical treatments indicated a cumulative tendency under high N rate and low precipitation. Forage yield did not demonstrate statistical differences on treatment and scheme level but varied with changing precipitation, while the maximum application rate suggested a

“…Nanofiltration and reverse osmosis can be used to separate multiply charged phosphates and singly charged nitrates or ammonium cations in the processing of FO draw solutions [ 135 , 136 ], anaerobic digestates [ 137 ], human urine [ 138 , 139 ], or urban wastewater [ 140 ]. Mechanisms based on the Donnan exclusion of coions provide rejection of large, highly hydrated, multiply charged phosphate anions and their concentration in the retentate, while smaller singly charged anions (e.g., NO 3 − , NH 4 + ) are transferred to the permeate.…”

The review describes the place of membrane methods in solving the problem of the recovery and re-use of biogenic elements (nutrients), primarily trivalent nitrogen NIII and pentavalent phosphorus PV, to provide the sustainable development of mankind. Methods for the recovery of NH4+ − NH3 and phosphates from natural sources and waste products of humans and animals, as well as industrial streams, are classified. Particular attention is paid to the possibilities of using membrane processes for the transition to a circular economy in the field of nutrients. The possibilities of different methods, already developed or under development, are evaluated, primarily those that use ion-exchange membranes. Electromembrane methods take a special place including capacitive deionization and electrodialysis applied for recovery, separation, concentration, and reagent-free pH shift of solutions. This review is distinguished by the fact that it summarizes not only the successes, but also the “bottlenecks” of ion-exchange membrane-based processes. Modern views on the mechanisms of NH4+ − NH3 and phosphate transport in ion-exchange membranes in the presence and in the absence of an electric field are discussed. The innovations to enhance the performance of electromembrane separation processes for phosphate and ammonium recovery are considered.

“…In addition, filtration separates the solid by retaining the solid particles that are bigger than the pore of the membrane on the membrane surface while allowing the liquid to pass through. Several technologies are available at a commercial scale to separate the solid and the liquid, such as the centrifuge decanter, the sedimentation tank, and filters . These technologies are normally developed for similar applications such as separation of solids from a liquid in a traditional AD.…”

Anaerobic digestion (AD) is an attractive and sustainable alternative for stabilizing solid organic waste and producing biogas or biomethane. However, it is carried out by slow‐growing bacteria and archaea and it normally demands a hydraulic retention time (HRT) of 20–60 days in the bioreactor. Although high‐rate AD methods and technologies have been developed, they are normally applied to liquid wastes such as wastewater. In this work, the theory and latest developments in high‐rate digestion of organic solid wastes are reviewed. The process is accomplished by running the AD in a two‐stage operation. The first stage involves dissolving the solid materials in water, using robust hydrolytic bacteria. The effluent is then filtered to remove any undigested material, which in some cases contains inhibitory compounds. The filtrate is then fed to bioreactors containing high cell density ADs such as flocculating bacteria (granules) or membrane bioreactors (MBR) to protect the sensitive and very slow‐growing methanogen. Different approaches to overcoming problems faced in the first stage of digestion are proposed in this review. These problems include slow digestion of lignocellulosic biomass or failure of digestion due to inhibition problems for feedstocks containing toxic compounds, and rapid acidification for easily degradable substrates. The principle, technology, benefits and drawbacks, and factors affecting the efficacy of each type of high cell‐density reactor are presented. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
