Critical analysis of life cycle inventory datasets for organic crop production systems
(Springer, 2022-04-20)
Purpose
Organic agriculture (OA) has gained widespread popularity due to its view as a more sustainable method of farming. Yet OA and conventional agriculture (CA) can be found to have similar or varying ...
Ammonium and Phosphate Recovery in a Three Chambered Microbial Electrolysis Cell: Towards Obtaining Struvite from Livestock Manure
(MDPI, 2021-10-27)
Ammonia and phosphate, which are present in large quantities in waste streams such as livestock manure, are key compounds in fertilization activities. Their recovery will help close natural cycles and ...
Environmental accounting of closed-loop maize production scenarios: Manure as fertilizer and inclusion of catch crops
(Elsevier, 2019-04-09)
The agri-food sector has moved towards a more linear production economy, partly caused by worldwide food demand. One clear example is the intensification of livestock production, with consequent ...
Treatment of swine manure: case studies in European’s N-surplus areas
(Universidade de São Paulo, 2016-09)
In this study, eight different manure treatment plants were monitored. The plants were four on-farm and four centralized treatment plants, all of them at full-scale level. Assessment includes a total ...
Anaerobic digestion and electromethanogenic microbial electrolysis cell integrated system: Increased stability and recovery of ammonia and methane
(Elsevier, 2017-12-18)
The integration of anaerobic digestion (AD) and a microbial electrolysis cell (MEC) with an electromethanogenic biocathode is proposed to increase the stability and robustness of the AD process against ...
Effect of harvesting age and size reduction in the performance of anaerobic digestion of Pennisetum grass
(MDPI, 2020-11-06)
In the rural zones of Latin American and Caribbean developing countries, the poorest households rely on traditional fuels such as firewood to meet their daily cooking needs. Many of those countries are ...
Hydrophobic membranes for ammonia recovery from digestates in microbial electrolysis cells: Assessment of different configurations
(Elsevier, 2021-03-01)
The combination of hydrophobic membranes and microbial electrolysis cells (MEC) was assessed in two different configurations in order to recover ammonia from anaerobically digested pig slurry. ...
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 ...
Startup strategy for nitrogen removal via nitrite in a BAF system
(Springer, 2018-10-26)
A biological aerated filter (BAF) pilot plant consisting of two reactors (aerobic and anoxic one) was used to determine a strategy to remove nitrogen via nitrite. RNA/DNA analysis was performed to assess ...
In-situ methane enrichment in continuous anaerobic digestion of pig slurry by zero-valent iron nanoparticles addition under mesophilic and thermophilic conditions
(Elsevier, 2021-08-27)
The effect of zero-valent iron nanoparticles (nZVI) addition on methane production during anaerobic digestion of pig slurry was assessed. Experiments were conducted using two experimental set-ups: batch ...
