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 ...
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 ...
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 ...
Development of a modified plug-flow anaerobic digester for biogas production from animal manures
(MDPI, 2019-07-08)
Traditional plug-flow anaerobic reactors (PFRs) are characterized by lacking a mixing system and operating at high total solid concentrations, which limits their applicability for several kinds of ...
The role of life cycle assessment in supporting sustainable agri-food systems: A review of the challenges
(Elsevier, 2016-06-15)
Life cycle thinking is increasingly seen as a key concept for ensuring a transition towards more sustainable production and consumption patterns. As food production systems and consumption patterns
are ...
Technological reliability of pollutant removal in different seasons in one-stage constructed wetland system with horizontal flow operating in the moderate climate
(Elsevier, 2019-12-17)
The aim of this work was to determine the technological reliability of pollutions removal in different seasons in one-stage constructed wetland system with horizontal flow operating in the conditions ...
Improved anaerobic biodegradability of wheat straw, solid cattle manure and solid slaughterhouse by alkali, ultrasonic and alkali-ultrasonic pre-treatment
(Taylor & Francis, 2018-09-07)
Wheat straw and animal wastes are important feedstock for biogas production in Europe. Yet, the high content of lignocellulosic and refractory materials causes the process to be relatively slow. Therefore, ...
Effect of different fertilization strategies on nitrogen balance in an outdoor potted crop of Osteospermum ecklonis (DC.) Norl. ‘Purple Red’ under Mediterranean climate conditions
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2013-07-15)
Fertilization management and meteorological conditions can affect leachate composition and the balance of nitrogen
(N) added during the cultivation of ornamentals. The main objectives of this study ...
Soil quality, properties, and functions in life cycle assessment: an evaluation of models
(Elsevier, 2016-06-10)
Soils provide essential ecosystem services for supporting both human and ecosystem needs and has been under pressures resulting from the intensification and expansion of human activities. In the last ...
Effect of Bacillus spp. direct-fed microbial on slurry characteristics and gaseous emissions in growing pigs fed with high fibre-based diets
(Elsevier, 2016-07-14)
A 26-day trial with 18 Pietrain × (Landrace × Duroc) pigs was conducted to investigate the effect of two dose levels of a specifically selected Bacillus spp. direct-fed microbial (DFM) product, on the ...
