Environmental, social and health benefits of alternative renewable energy sources. Case study for household biogas digesters in rural areas
(Elsevier, 2021-03-15)
In rural areas of Colombia, liquefied petroleum gas (LPG) is the preferred option available for cooking. However, the poorest households rely on firewood (FW) to meet their daily cooking needs, because ...
Treatment of the Supernatant of Anaerobically Digested Organic Fraction of Municipal Solid Waste in a Demo-Scale Mesophilic External Anaerobic Membrane Bioreactor
(Frontiers Media, 2021-04-12)
Conventional aerobic biological treatments of digested organic fraction of municipal solid waste (OFMSW) slurries–usually conventional activated sludge or aerobic membrane bioreactor (AeMBR)–are inefficient ...
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 ...
Operationalising emission and toxicity modelling of pesticides in LCA: the OLCA-Pest project contribution
(Springer, 2022-04-14)
Purpose
Current field emission modelling and toxicity characterisation of pesticides suffer from several shortcomings like mismatches between LCI databases and LCIA methods, missing characterisation ...
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 ...
Combined efects of drought and simulated pathogen attack on root exudation rates of tomatoes
(Springer, 2023-12-14)
Background and aims
Food production is threatened by direct climate change effects including drought. Indirect effects, including changes in plant-pathogen dynamics and increased susceptibility to ...
Supplementation of gilthead seabream (Sparus aurata) diets with spices as a functional strategy to control excess adiposity through lipid, cholesterol and bile acid metabolism, and to induce an immunomodulatory intestinal regulation
(Elsevier, 2023-11-17)
Reductions in fish oil content in aquafeeds can generate physiological and immunological disorders in farmed fish, associated to low dietary levels of n-3 long chain polyunsaturated fatty acids (n-3 ...
Assessment of social aspects across Europe resulting from the insertion of technologies for nutrient recovery and recycling in agriculture
(Elsevier, 2022-02-02)
The potential beneficial and harmful social impacts generated by the introduction of novel technologies, in general, and those concerning nutrient recovery and the improvement of nutrient efficiency in ...
Extrusion of Different Plants into Fibre for Peat Replacement in Growing Media: Adjustment of Parameters to Achieve Satisfactory Physical Fibre-Properties
(MDPI, 2021-06-10)
Peat is a highly contentious input in agriculture. Replacing or reducing peat by substitution with lignocellulosic biomass processed into fibre by twin-screw-extrusion could contribute to more sustainable ...
Effect of decreasing dietary crude protein in fattening calves on the emission of ammonia and greenhouse gases from manure stored under aerobic and anaerobic conditions
(Elsevier, 2022-03-01)
Dietary strategies can potentially help to reduce nitrogen (N) emissions and decrease the environmental impact of beef production. This study aimed to evaluate the effects of dietary crude protein (CP) ...
