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 ...
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 ...
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) ...
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 ...
Freshwater ecotoxicity assessment of pesticide use in crop production: Testing the influence of modeling choices
(Elsevier, 2018-10-28)
Pesticides help to control weeds, pests, and diseases contributing, therefore, to food availability. However, pesticide fractions not reaching the intended target may have adverse effects on the environment ...
A high-resolution life cycle impact assessment model for continental freshwater habitat change due to water consumption
(Elsevier, 2021-03-22)
Global value chains and climate change have a significant impact on water resources and increasingly threaten freshwater ecosystems. Recent methodological proposals for life cycle impact assessment ...
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 ...
