“…Benefits from application of biosolids to agricultural land are well documented (e.g., Bastian, 1997;Rigby and Smith, 2014). For example, recycling of biosolids contributes to close the natural C and nutrients cycles, maintain soil fertility and soil organic matter, and mitigate the depletion of naturally available, although finite resources, such as rock phosphate (Diacono and Montemurro, 2010;Powlson et al, 2012;Reijnders, 2014). However, in practice, recycling biosolids to agriculture presents both the wastewater industry and end-users with several challenges, including: land-bank availability in the proximity of wastewater treatment works, soil P status and potential P enrichment of surface waters, the concentrations and phyto-availability of nutrients in biosolids, potential build-up of heavy metals in soil, their uptake by crops grown on the soil and subsequent transfer to the food chain, and logistics issues such as cost of transport, storage, handling and field application (Hogan et al, 2001;Elliott et al, 2002;O'Connor et al, 2004;Clarke and Cummins, 2015).…”

Field-scale experiments in four crop seasons established the agronomic performance of biosolids-derived organomineral fertilizers (OMF) for winter wheat (Triticum aestivum L.) production in England. Two OMF formulations (OMF 10 10:4:4 and OMF 15 15:4:4) were compared with urea and biosolids granules (≈5:6:0.2) to determine crop responses and fertilizer eff ects on soil chemical properties. Fertilizers were applied at N rates between 0 and 250 kg ha -1 at regular increments of 50 kg ha -1 N. Average grain yields with OMF 10 and OMF 15 were higher than with biosolids granules, but lower than with urea (P < 0.05). Th e optimum N application rates, and corresponding grain yields, were 245 and 7900 kg ha -1 for biosolids, 257 and 9100 kg ha -1 for OMF 10 , 249 and 9500 kg ha -1 for OMF 15 , and 225 and 10350 kg ha -1 for urea, respectively. Diff erences in grain yield between fertilizer treatments were explained by diff erences in yield components, particularly number of grains and thousand-grain-weight. Grain-N recoveries were 31% for biosolids, ≈40% for OMF, and 52% for urea. Organomineral fertilizers-induced changes in soil extractable P and soil P Index were not signifi cant. Th us, application of OMF replenished P offt ake by the crop and therefore supported the choice of the proposed OMF formulations. By contrast, extractable P increased in biosolids and decreased in urea-treated soils, respectively. Heavy metals in soil were unaff ected by fertilizer treatment and lower than permissible limit values. Th e use of OMF for winter wheat production appears to be a sustainable approach to recycling biosolids to land.

“…In particular, high amount of phosphorus promotes algae growth in water, since it is usually regulated by microorganisms, which in its turn decreases oxygen concentration and leads to eutrophication (extraordinary growth of algae as a result of excess nutrients in water bodies) on rivers, lakes, and seas worldwide [5,6]. Due to phosphorus is a non-renewable element and huge amount of phosphorus is lost annually for lack of phosphorus recovery, its recycling is of great interest especially with increasing demands, such as in the agriculture [7] as a fertilizer [8,9] or industrial usages as ingredients for human food, pharmaceuticals, detergents, and food additive in the animal feed [10,11]. Therefore, phosphorus is a critical element in water, where it was found frequently contained in groundwater, domestic and industrial wastewaters.…”

Highlights• Immobilization of magnetite nanoparticles on cationic polymer was synthesized.• Phosphate removal using magnetite based nanocomposites was tested.• Adsorption isotherms of phosphate at two pH; 5 and 7 were performed.• Different isotherms models were applied for experimental data fitting.• Regeneration and reusability of the magnetite based nanocomposites were carried out. Graphical Abstract 2 AbstractA novel nanocomposite based on magnetite nanoparticles (Fe3O4-NPs) immobilized on the surface of the cationic exchange polymer, C100, using a modification of the coprecipitation method was developed to obtain magnetic nanocomposites (NCs) for phosphate removal and recovery from water. High resolution TEM-EDS, SEM, XRD, and ICP-OES were used to characterize the NCs. The continuous adsorption process by the so-called breakthrough curves was used to determine the adsorption capacity of the Fe3O4 based NC. The adsorption 3 capacity conditions were studied under different conditions (pH, phosphate concentration and concentration of NPs). The optimum concentration of iron in the NC for phosphate removal was 23.59 mgFe/gNC. The sorption isotherms of this material were performed at pHs 5 and 7.Taking into account the real application of this novel material in real water, the experiments were performed at pH 7, achieving an adsorption capacity higher than 4.9 mgPO4-P/gNC.Moreover, Freundlich, Langmuir and a combination of them fit the experimental data and were used for interpreting the influence of pH on the sorption and the adsorption mechanism for this novel material. Furthermore, regeneration and reusability of the nanocomposite were tested obtaining 97.5 % recovery of phosphate for the first cycle and at least 7 cycles of adsorptiondesorption were carried out with more than 40% of recovery. Thus, this work described a novel magnetic nanoadsorbent with promoting properties for phosphate recovery in wastewater.

“…However, several studies predict (e.g., [71][72][73][74][75][76][77][78]) that with increasing use of biotic materials (e.g., for biofuels) in the next decades not enough land and phosphorus will be available to meet all human needs (e.g., for food, feed and industrial processes). However, both challenges are rather universal and are less related to one specific species used as a biotic material [79,80]. Only phosphorus and no other soil nutrients are considered, because phosphorus is a limited resource itself and thus can limit the production of agricultural products significantly.…”

Assessing the Availability of Terrestrial Biotic Materials in Product Systems (BIRD)

Availability of abiotic resources has been a topic of concern in recent years, resulting in several approaches being published to determine their availability on country and product level. However, the availability of biotic materials has not been analyzed to this extent yet. Therefore, an approach to determine possible limitations to availability of terrestrial biotic materials over the entire supply chain is introduced. The approach considers 24 categories overall as well as associated category indicators for the five dimensions: physical, socio-economic, abiotic, social and environmental constraints. This ensures a comprehensive availability assessment of bio-based product systems. The approach is applied to a case study comparing biodiesel produced from rapeseed and soy beans. The study shows that the determination of indicator values is feasible for most categories and their interpretation leads to meaningful conclusions. Thus, the approach leads to a more comprehensive assessment of availability aspects and supports better informed decision making in industry and policy.
