“…Thessaly is a typical example of a region in Greece with strong economic activity in the primary sector. Because there are significant amounts of unused agricultural and animal waste in the area, they have the potential to revitalize and raise the region's proportion of renewable energy sources [27,28]. In this research region, the output of livestock and agricultural residues was predicted to be 4.8 × 10 6 t•yr.…”

In recent years, due to the circular economy, the use of green energy forms, such as biofuels and biogas from anaerobic digestion of fermentable materials (e.g., agricultural and livestock residues) has entered our lives. According to the International Energy Agency it is estimated that the needs in 2040 will be 48% higher than in 2012 so all political decisions have converged on an urgent need for the use of more and more renewable and green energy. Considering the overall economic activity of these sectors in the region of Thessaly, the aim of this study is to highlight the residues from agricultural and livestock activities in the primary sector and calculate the annual biomass production, the methane and biogas potential, the electrical and thermal energy that can be produced from these wastes, as well as the solid residue that can be used to improve the soil of the region. The study was based on data referring to the years 2015 to 2020. The production of livestock and agricultural residues, averaged over the above six-year period in the study area, was estimated at approximately 4.8 × 106 t·yr.−1, with livestock residues accounting for 83% and agricultural residues for 17%. Furthermore, the total residues can produce an average biogas potential of approximately 4.7 × 106 m3·yr.−1, while the amount of electricity that can be produced ranges from 708–1091 GWh·yr.−1, and the corresponding thermal energy from 1112–1577 GWh·yr.−1. As a result of the complete anaerobic digestion process, a solid residue could also be obtained for the improvement of the region’s soil, which translates into a quantity in the range of 4.01 × 104 to 5.10 × 104 t·yr.−1.

“…These bio-electrochemical processes are characterized by energy self-sufficiency and low sludge yields (Zamalloa et al, 2013). In addition, they have also shown potential in the efficient removal of recalcitrant pollutants (Huang et al, 2016;Yang et al, 2022). Processes for nutrient and energy recovery from BW are summarized in Table 4.…”

Blackwater (BW), consisting of feces, urine, flushing water and toilet paper, makes up an important portion of domestic wastewater. The improper disposal of BW may lead to environmental pollution and disease transmission, threatening the sustainable development of the world. Rich in nutrients and organic matter, BW could be treated for resource recovery and reuse through various approaches. Aimed at providing guidance for the future development of BW treatment and resource recovery, this paper presented a literature review of BWs produced in different countries and types of toilets, including their physiochemical characteristics, and current treatment and resource recovery strategies. The degradation and utilization of carbon (C), nitrogen (N) and phosphorus (P) within BW are underlined. The performance of different systems was classified and summarized. Among all the treating systems, biological and ecological systems have been long and widely applied for BW treatment, showing their universality and operability in nutrients and energy recovery, but they are either slow or ineffective in removal of some refractory pollutants. Novel processes, especially advanced oxidation processes (AOPs), are becoming increasingly extensively studied in BW treatment because of their high efficiency, especially for the removal of micropollutants and pathogens. This review could serve as an instructive guidance for the design and optimization of BW treatment technologies, aiming to help in the fulfilment of sustainable human excreta management.

“…The successful clinical use of penicillin in 1940 has increased the use of antibiotics in livestock vaccinations and disease treatments (Oberoi et al, 2019). However, antibiotics are not entirely absorbed and are excreted in urine and feces, thus contributing to antibiotic contamination of the soil (Yang et al, 2022). In particular, introducing antibiotics to water bodies can cause irreversible damage to aquatic ecosystems, and this increased antibiotic pollution, due to livestock breeding, is considered a signi cant potential risk to environmental ecology and human health .…”

Inoculants with lactic acid bacteria (LAB) are commonly used in silage production.The potential effects from LAB inoculants in silage containing antimicrobial components have not been well explored. Herein, the harvested alfalfa and were thoroughly mixed with dried Leonurus japonicus Houtt. (LJH) at a ratio of 9:1 on fresh weight basis, and treated without (CK) or with either a lactic acid bacterial inoculant (L; Lentilactobacillus buchneri). The mixtures were stored under anaerobic conditions in vacuum-sealed polyethylene bags for 30 days at ambient temperature. The L-treated silage exhibited high levels of water-soluble carbohydrates (4.98% dry matter (DM)) and acid detergent fiber (27.88% DM). Compared to that of treatment CK, treatment with L increased the acetic acid content of the silage, as result from increased (P < 0.05) bacterial dominance and decreased (P < 0.05) bacterial richness indices (e.g., Pielou’s E, Shannon, and Simpson) in the pre-storage period. However, these changes gradually reduced as the storage length increased. Treatment L reshaped the bacterial community structure of silage, by increasing prevailiance of Lactobacillus and reducing relative abundances of Enterococcus and Weissella. However, the principal coordinate and bray curtis index analyses illustrated that samples from the L-treated silages exhibited similarities to the CK samples post-fermentation. Overall, the effect of LJH on LAB was only observed in the later stages of fermentation, which did not sufficiently change the silage quality. Hence, using LJH in silage is vital for clean livestock production without compromising the function of LAB when mixed with alfalfa silage.
