Closing nutrient loops in a maize rotation. Catch crops to reduce nutrient leaching and increase biogas production by anaerobic co-digestion with dairy manure
(Elsevier, 2021-04-18)
Three catch crop species, ryegrass, forage rape and black oat, were grown between successive rotations of maize to reduce nitrogen leaching due to maize fertilization with digested dairy manure. Catch ...
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. ...
Methane potential of fruit and vegetable waste: an evaluation of the semi-continuous anaerobic mono-digestion
(Taylor & Francis, 2018-09-02)
The anaerobic digestion (AD) of a high diversity blend of fruit and vegetable waste (FVW) generated in tropical conditions as a single substrate was performed. A continuously stirred tank reactor (CSTR) ...
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, ...
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 ...
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 ...
Towards a standardization of biomethane potential tests
(IWA Publishing, 2016-09-19)
Production of biogas from different organic materials is a most interesting source of renewable energy.
The biomethane potential (BMP) of these materials has to be determined to get insight in ...
The importance of including soil carbon changes, ecotoxicity and biodiversity impacts in environmental life cycle assessments of organic and conventional milk in Western Europe
(Elsevier, 2019-01-04)
Estimates of soil carbon changes, biodiversity and ecotoxicity have often been missing from life cycle assessment based studies of organic dairy products, despite evidence that the impacts of organic ...
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 ...
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 ...
