Solar drying in the vineyard: a sustainable technology for the recovery of nutrients from winery organic waste
(IWA Publishing, 2020-07-09)
The present study describes a pilot-scale experimental validation of a forced-convection greenhouse solar dryer, combined with a biofilter, for controlled atmospheric emissions. This set-up was applied ...
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 ...
Biogas production from slaughterhouse waste: Effect of blood content and fat saponification
(Elsevier, 2021-08-12)
The effect of fat saponification and the inclusion or exclusion of blood in slaughterhouse mixtures were assessed in terms of anaerobic digestion performance. Mixtures of animal by-products (ABP) were ...
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 ...
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 ...
Near infrared spectroscopy for fast characterization of animal by products feedstocks for biogas production: Calibration of a handheld device
(Elsevier, 2022-12-28)
Anaerobic digestion performance is highly influenced by the chemical composition and flow of substrates. This work evaluates the feasibility of a handheld near infrared spectrometer to predict moisture, ...
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) ...
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 ...
