“…Previous attempts have been made in this regard using the nutrient rich sludge to culture microalgae. However, the alga products from this arrangement have been reported to have limited applications due to the inability to produce algal materials free from contaminants (Shen et al, 2019). This singular disadvantage has restricted the use of the algae materials produced from this method to bio-energy purposes.…”

“…Mattress is among the main products of EFS. In ectopic fermentation, high-temperature-resistant microorganisms are used to degrade feces and urine by aerobic fermentation (Jiang, 2020; Yang, 2018;Shen, 2019). Then, mattresses are used as organic fertilizer for agricultural soil.…”

“…If the amount exceeds the acceptable range, it may have adverse effects on the living environment of the normal soil and the horizontal transmission of drug resistance genes in the digestion area. Moreover, antibiotics in mattress have a negative effect on the microbial growth of mattress (Shen 2019). E cient and low-cost treatment of mattress, the environmental safety of antibiotic consumption area, and the quality of mattress products can be ensured by solving the problems on antibiotic residues in matters of EFS and the safety evaluation of mattress.…”

Mattress is among the main products of ectopic fermentation system (EFS),however, the research on the data of antibiotic residues in the mattress of EFS and risk assessments of mattress have not been conducted. This study involved a scale survey to assess the levels and distributions of 54 antibiotics residues, including 4 tetracyclines, 19 quinolones, 22 sulfonamides, 3 amphenicols, and 6 macrolides in mattress on 12 swine farm that uses ectopic fermentation systems (EFS) in Zhejiang Province. A total of 25 antibiotics were detected in mattress, and the total residue amount of antibiotics in mattress samples of each farm was 0.77–28.2 g/T. Chlortetracycline had the highest contribution rate, and the residue amount of antibiotics in mattress is not entirely determined by the start-up time of EFS but is related to the use of feed containing antibiotics, medication habits, the level of mattress management, and maintenance methods of EFS. The risk assessments of antibiotics in the mattress were carried out. The results show low risk for soil on swine farm that uses EFS.

“…However, further process improvements are still needed to solve the issues associated with biogas residues, which may be more expensive. In general, environmentally sustainable and cost-effective approaches to treat livestock manure would be beneficial for addressing the urgent concerns of surrounding livestock waste [8][9]. Although anaerobic digestion of manure has been achieved in rural Asia, farm-scale factory capital cannot always be offset by biogas production [10][11].…”

A study was designed aiming at the degradation of organic matter in liquid phase of pig manure, the inactivation of pathogenic microorganisms and biogas production at different storage temperatures. A low cost rapid anaerobic fermentation, and biogas sewage storage system was constructed. After the four-day anaerobic fermentation, three treatments were set up: the average temperature of spring and autumn (16.1ºC), summer (25ºC), and winter (0.6ºC) in Yantai City was used as storage temperature for 90 days, respectively. The results showed that the biogas potential of anaerobic fermentation and biogas sewage storage at 16.1ºC and 25ºC was higher than that stored at 0.6ºC. During the experiment, total solids (TS) and organic matter contents in fecal sewage were decreased with time, and the value was determined at 25ºC. Total phosphorus and potassium contents in biogas sewage did not change significantly over time, but the total nitrogen content decreased. The content of the 5 day biological oxygen demand (BOD 5), the chemical oxygen demand (COD Cr) and suspended solid concentration (SS) in fecal sewage showed a downward trend over time. The egg mortality of Ascaris lumbricoides increased in different degrees under the three storage conditions. The number of E. coli in biogas sewage stored at 0.6ºC and 16.1ºC showed a downward trend, and the number of E. coli in biogas sewage stored at 25ºC was significantly higher than at 0.6ºC and 16.1ºC. The comprehensive analysis showed that at temperature 25ºC, the an-aerobically produced fecal sewage after fermentation had best potential for biogas production.
