To develop technology to efficiently utilize digestate from methane fermentation in agricultural production, the application of for supplying nutrients sweet potato cultivation was investigated sandy soil. Different strengths diluted with water were applied plants as and nutrient supplies determine appropriate strength production The growth cultivated also compared that a commercial chemical solution. rate tuberous roots 1/20 greatest among treatments different (1/80–1/2) solutions (1/4–1). Consequently, we proposed system using bottom irrigation method fermentation, which will be applicable semiarid regions. In conclusion, results this study can effectively used regional combined contribute increasing food well establishment resource recycling society.

This review focuses on the use of membrane techniques to recover nutrients from liquid fraction digestate (LFD) and emphasizes their role in promoting principles circular economy. A range separation processes are examined, including microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), forward (FO), distillation (MD) new tools such as contactors (MCs) with gas-permeable membranes (GPMs) electrodialysis (ED). Key aspects that analyzed include nutrient concentration efficiency, integration biological strategies mitigate challenges fouling, high energy requirements scalability. In addition, innovative hybrid systems pretreatment examined for potential improve recovery rates sustainability. The also addresses economic technical barriers full-scale application these technologies identifies future research directions, improving materials reducing consumption. comprehensive assessment highlights contribution sustainable management bio-based fertilizer production.

Phosphorus (P) is critical for plant growth, but global reserves are exhausting within 250-300 years, therefore enhancing phosphate recycling crucial the future. Biogas digestate, rich with nutrients a promising resource nutrient recovery. Conventional solid-liquid separation shifts approximately 35 % of total P in digestate to solid phase. Separation trials additive treatment using screw press 0.75 mm sieve were performed at University Hohenheim's full-scale biogas plant. After 22 h, 67.41 (kieserite treatment) and 52.35 (strawflour shifted Treatment kieserite enhanced shift into phase by forming non-labile fractions through chemical bond between Mg

The problem of food being wasted in households has become an essential challenge recent years. Food waste can be valorized accordance with the principles sustainable development, including as a source energy. This study analyses potential anaerobic fermentation, pyrolysis, ethanol incineration, and composting to treat waste, focusing on its energy yield. research considered two scenarios for generating Poland both near term (2030) long (2050). Scenarios were proposed regions different levels urbanization demographic trends. criteria selection technologies energy-efficient processing from identified, taking into account current state these technologies, their prospective changes, nature regions, trajectory generation, spatial generation rate, potential. Technologies like methane fermentation thermochemical methods should developed densely populated areas high rate. Among processes, fast pyrolysis will provide most significant benefits, followed by moderate biocarbonization—at similar levels. Incineration is placed between carbonization gasification. In less lower rates, combining substrates co-processing green considered. Biocarbonization systems integrated rural regions.

Significant share of microplastics entering wastewater treatment is accumulated in sewage sludge, which commonly treated by anaerobic digestion. The digestate typically separated to solid and liquid fractions, the fraction often land-applied. However, division between these fractions poorly understood. Thus, we investigated occurrence (>20 μm) at an digester subsequent solid-liquid separation. Sewage sludge exhibited 7600 ± 6800 7200 1100 per g dry weight, respectively, indicating that digestion can decrease fluctuation microplastics' sludge. microplastic flow was predominantly directed fraction, while carried about 1 % microplastics, mostly polymers with low density (polyethylene polypropylene). We also factors affecting identification Raman spectroscopy. Microplastic degradation presence organic matter after oxidative sample preparation, affected spectra different microplastics. For polyethylene polypropylene, changes did not interfere recognizing their characteristic peaks, allowing high-certainty identification. In contrast, polyamide notably compromised as signal-to-noise ratio be deteriorated natural misidentified polyamide.

In line with the concept of sustainable agriculture, efforts should be made to increase green energy yield and minimize environmental impact mineral fertilizers, maintaining high agricultural productivity. alignment principles development, plant biomass-based is considered promising. A deep understanding enhancements anaerobic digestion process using biomass, along digestate post-treatment for regenerative agriculture improvements, are key elements achieve sustainability goals. This article describes innovative methods biomass pre-treatment aimed at enhancing biogas fertilizing potential obtained digestate. Moreover, valuable insights into conditioning valorization discussed. Among these, separation stabilization techniques emphasized. Furthermore, this provides a comprehensive source knowledge on soil quality, fertility, organic carbon sequestration, microbiota. The findings contribute broader how impacts agriculture.

The environmental impact of livestock by-products presents significant challenges, particularly in regions with intensive farming and high pollution levels, such as the Po Valley. This study evaluated effectiveness biochar wood vinegar reducing gaseous emissions during laboratory-scale storage slurry, digestate, liquid fractions. Various types applications biochar, both without vinegar, were tested across three independent incubation periods varying durations. results showed that ammonia (NH3) lower from slurry compared to raw digestate fraction, while methane (CH4) exhibited opposite trend. Pyrolysis effectively reduced NH3 by 47% on average when applied a 5 cm surface layer. However, its was inconsistent mixed into material or produced via gasification. Biochar activated significantly 61%, but it also led increased CH4 CO2. Nitrous oxide (N2O) detected only after at least one month higher used cover alone vinegar. Overall, applying activating proved effective by-products. varied depending type method application, respect emissions, highlighting need for careful consideration using vinegar-activated biochar.
