“…Overall, the yields in this work were much higher than the reported HLA(2.6%-19.9%) and FLA results (3.72%-30.0%) via composting of food wastes [31][32][33] or manure [34][35][36] , presumably because no organic matter was consumed through microbial metabolism.…”

The direct disposal of waste milk (WM) leads to severe environmental pollution and resource loss. Considering the high content of nutrients, WM has a potential as an ideal raw material for organic fertilizer. In this work, base-activated persulfate (KOH/PS) was used as a new artificial humification technology to transform WM into product with 45.3% of fulvic-like acid (FLA) and 18.9% of humic-like acid (HLA) in 1 hour. Therein, FLA had more active groups (-COOH, -CNOH, -OH) than natural fulvic acid likely owing to hydroxylation, carboxylation and the Millard reaction. Reactive species of •OH and SO4−• generated in KOH/PS system may be related to degradation or polymerization reactions during humification. The product was mixed with attapulgite to fabricate a slow-release nano FLA fertilizer which could increase the yield of chickweeds by 107% compared with the blank as well as the abundance of beneficial bacteria in soil. Overall, this study provided a rapid method for the recycling of waste food and highly-concentrated organic wastewater, which may have a huge application prospect in sustainable agriculture.

“…Foam box small pile fermentation was employed for microorganism screening and small-scale feed SSF. During screening, CM, which is commonly used for compost ( Zhang et al., 2021 ), was employed as a positive control to detect heating in foam box small pile fermentation. The temperature-heating profile (THP) of the CM treatment ( Figure 1 ) showed that the AASMS-supplemented CM could be efficiently fermented, and the microbial metabolic process-produced heat increased the temperature earlier than the CK treatment, which was natural fermentation without artificial inoculation with foreign microorganisms.…”

“…It seemed very difficult to find the law of HIAP dosage influencing HA and FA. During PG-amended chicken manure/corn stover composting [14], the change of HA and FA contents along the composting time always show in the following order: CK > 5% > 10% PG treatment. In terms of the effect of HIAP dose on HA and FA, the HA during whole SS composting and the FA at the thermophilic phase were similar to the reported results [14].…”

“…Attapulgite (AP) is a hydrous magnesium-aluminum silicate mineral with a chainlayered structure, large surface area, and excellent cation exchange capacity, which has the characteristics of low cost, good biology, and soil compatibility in soil application. AP has been demonstrated as a promising amendment to reduce the phytotoxicity of heavy metals (HMs) for direct SS soil utilization [7,8] and as a promising additive to reduce the bioavailability of HMs [9][10][11] and the emission of greenhouse gases [12,13], enhance the degradation of organic pollutants [10,13], promote composting process [14] during the composting of different biosolid wastes. To our best knowledge, research on the effect of AP and its dosage on SS composting humification is hitherto rare based on the heterogeneity of the SS composting matrix.…”

We first revealed the behavior and biochemical mechanism of high iron attapulgite (HIAP) and different dosages affecting sewage sludge (SS) composting. HS/TOC ratio increased, but HA/TOC and HA/FA ratios reduced with the increase in HIAP dose. High-dose HIAP promoted the formation of more HS by weak catalytic effect but could bind more FA than HA by strong adsorption effect to inhibit the polymerization of the adsorbed FA into HA. Mixing SS with HIAP and subsequent composting as two consecutive processes during HIAP-amended composting significantly influenced the species distribution of heavy metals (HMs) Cu, Zn, and Cr. Each process roughly contributed one-half to HMs passivation. The bioavailable fraction (BF) of HMs reduced with the increase of HIAP dose. HIAP dose greatly affected the microbial community. Both 1% and 5% HIAP treatments promoted Proteobacteria and Firmicutes, but 10% HIAP promoted Actinobacteriota and Bacteroidota. At the thermophilic phase, HIAP dose greatly affected core thermophilic microbial genera, which were significantly correlated to pile temperature and pH value. In the maturity stage, core microbial genera in different treatments were basically similar and closely correlated to the bioavailable fraction (BF) of HMs and HA, and the influence order was BF–Cr > BF–Cu > BF–Zn > HA. The optimal 5% HIAP dose was recommended.
