Over the years, different solutions were developed and tested to reduce emissions of ammonia particulate matter from livestock facilities. The environmental performances these not always evaluated in detail. This study examines footprint pig production at farm gate, with a focus on housing. Using Life Cycle Assessment, impact transition Spain two finishing farms Italy was considering three scenarios (one baseline them involving an air treatment technology: wet scrubber or dry scrubber). goal quantify scenarios, identify key hotspots, assess reduction efficiency due assessed technologies, analyze trade-offs that come use potential for improvements. Both scrubbers showed reducing housing, affecting categories related pollutants such as matter, acidification eutrophication. However, there between energy resource use. infrastructure consumables required operate added impacts compared baseline. more favorable balance emission trade-offs. In this regard, results similar Spanish Italian farms, although slight variations.

Reviewing Improved Anaerobic Digestion by Combined Pre-Treatment of Waste-Activated Sludge (WAS)

Sustainability, Journal Year: 2024, Volume and Issue: 16(15), P. 6419 - 6419

Published: July 26, 2024

The anaerobic digestion of wastewater treatment sludge (WAS) produces a “green” biogas while reducing the amount residual sludge. To increase yield biogas, several individual or combined pre-treatment methods WAS can be used. These substantially reduce volatile suspended solids (VSSs) and their associated total chemical oxygen demand (TCOD). Pre-treating will methane by 15 to 30%. Although have been dealt with in research large-scale operations, (hybrid) not previously reviewed. Here, different hybrid are reviewed, including (1) thermochemical hydrolysis pre-treatment, using an alkaline acid addition enhance solubilization cells production; (2) high-pressure homogenizer combining mechanical treatment; (3) ultrasound capable solubilizing organic compounds mechanisms, such as fast effective disruption increasing effect (NaOH) (4) microwave which enhances at least 20% comparison performance each separate process; (5) (MW) peroxidation (SSs), quickly (<5 min) disintegrated MW irradiation 80 °C; (6) ozone peroxides powerful oxidizing agents; (7) pulsed electric field (PEF) pretreatment.

Abstract Surge in global population and shift toward animal‐based diets have accelerated expansion of livestock production, posing various environmental challenges. It requires inventorying localized, activity‐specific, indicator‐extended multidimensional eco‐environmental burdens revealing their transfers within interregional trade to inform holistic production management from both consumption sides. Herein, we construct a life cycle framework covering multiple species, feeding regimes, activities evaluate nine impacts ending up as human health, ecosystem quality resource scarcity Chinese provincial regions. Multi‐regional input‐output analysis is then conducted trace these embedded associated with production. Results indicate that fine particulate matter formation (mainly by housing) climate change enteric fermentation) contribute greater than 60% 30% health burdens.

ABSTRACT Direct measurements of greenhouse gas emissions from the increasingly intensified African livestock production are important to assess locally available mitigation strategies. As such, were conducted March June using static flux chambers quantify emission rates CH 4 , N 2 O, and CO manure in poultry pig systems Cameroon. Emissions measured two layer barns, facilities, six broiler farms, one farm with Brahman birds. Mean factors inside barns 0.06–0.21 602–958 mg animal −1 h for 2, respectively, 21–112 µg O. four wood shavings as bedding material 0.31–1.22 355–1884 2.33–1052 Broiler O 971.38 ± 250.23 26.14 30.27 underneath a meshed floor barn shelter bare soil, respectively. storage tank wastewater piggery 8.30 7.36 40.41 5.54 m −2 min 2.80 1.67 outdoor storages mixture 0.76–0.9 69–136 10–15 depended highly on management systems. lower compared manure.

Anaerobic Digestion of Cattle Manure Contaminated with an Antibiotic Mixture: A Nature-Based Solution for Environmental Management

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 353 - 353

Published: Feb. 8, 2025

Anaerobic digestion (AD) is a waste-to-energy strategy that leverages natural microbiological processes. It increasingly used in farms to treat manure, resulting biogas for energy production and digestate as fertiliser. However, animal manure often contains antibiotic (AB) residues, raising concerns about their impact on AD efficiency potential spread through use. This multidisciplinary study evaluated the effects of an AB mixture (enrofloxacin, ciprofloxacin sulfamethoxazole) CH4 production, microbial community (Fungi, Bacteria Archaea) dynamics resistance gene (ARG) presence. The experiment cattle manure/digestate ratio 1:35, typical real digesters, with concentrations set at low (2.5 mg kg−1 each) high (7.5 levels. ABs affected cumulative (ranging from 5939 6464 mL) only highest concentration. After 51 days, sulfamethoxazole reached residual levels, while enrofloxacin were partially degraded (<50%), but ARGs significantly reduced. community, particularly prokaryotes, exhibited resilience, maintaining efficient production. Overall findings strongly suggest effective treatment producing good fertiliser, also reducing ARG content well mitigating emissions into atmosphere.
