Examining the perspectives of using manure from livestock farms as fertilizer to crop fields based on a realistic simulation
(Elsevier, 2021-10-13)
Intensive livestock production has a negative environmental impact by producing large amounts of animal dejections, which, if not properly managed, can contaminate nearby water bodies with nutrient ...
Selection and application of agri-environmental indicators to assess potential technologies for nutrient recovery in agriculture
(Elsevier, 2021-12-13)
The adverse effects of agriculture and livestock production on the environment are well-known and require mitigation in order to achieve sustainability in the food production chain. This study focused ...
Biogas Upgrading and Ammonia Recovery from Livestock Manure Digestates in a Combined Electromethanogenic Biocathode—Hydrophobic Membrane System
(MDPI, 2021-01-19)
Anaerobic digestion process can be improved in combination with bioelectrochemical systems in order to recover energy and resources from digestates. An electromethanogenic microbial electrolysis cell ...
Effectiveness of precision feeding in reducing N excretion in dairy cattle
(Elsevier, 2023-07-01)
Two periods enrolling 56 (milk yield 36.2 ± 7.91 kg/d) and 58 (milk yield 32.4 ± 4.99 kg/d) grouped-fed dairy cows were performed to evaluate nutrient adjustment and N emissions of a precision feeding ...
Struvite-based composites for slow-release fertilization: a case study in sand
(Nature Research, 2022-08-19)
Struvite (St) recovered from wastewaters is a sustainable option for phosphorus (P) recovery and fertilization, whose solubility is low in water and high in environments characterized by a low pH, such ...
Bioaugmentation of Native Fungi, an Efficient Strategy for the Bioremediation of an Aged Industrially Polluted Soil With Heavy Hydrocarbons
(Frontiers Media, 2021-03-31)
The concurrence of structurally complex petroleum-associated contaminants at relatively high concentrations, with diverse climatic conditions and textural soil characteristics, hinders conventional ...
Modulation of gut microbiota and intestinal immune response in gilthead seabream (Sparus aurata) by dietary bile salt supplementation
(Frontiers, 2023-04-24)
Given their role in lipid digestion, feed supplementation with bile salts could be an economic and sustainable solution to alterations in adiposity and intestinal inflammation generated by some strategies ...
Performance and environmental accounting of nutrient cycling models to estimate nitrogen emissions in agriculture and their sensitivity in life cycle assessment
(Springer, 2021-02-04)
Purpose
Several models are available in the literature to estimate agricultural emissions. From life cycle assessment (LCA) perspective, there is no standardized procedure for estimating emissions of ...
Combined Acidification and Solar Drying of Pig Slurries for Nutrient Recovery and Controlled Atmospheric Emissions
(MDPI, 2021-01-25)
The solar drying of pig slurries was tested in a pilot-scale greenhouse (10 m2 footprint), operated with forced ventilation under low and high solar irradiation in Mediterranean conditions. Gaseous ...
Acidification and solar drying of manure-based digestate to produce improved fertilizing products
(Elsevier, 2023-03-13)
The increase in energy and fertilizer consumption makes it necessary to develop sustainable alternatives for
agriculture. Anaerobic digestion and digestates appeared to be suitable options. However, ...
