Chair: Prof. Dr. JánGADUS,SUANitra,Slovakia.
Co-Chairs: Prof. Dr. Neculai MUNTEANU, UASVM Iasi, Romania.
Prof. Dr. Istvàn SZABO, SZIU Gödöllő, Hungary.
Altogether 9 oral and 5 poster papers were presented during the 3 sessions (IIa, IIb, Poster session II.). General scientific level of contributions was of high standard and scientific areas from the sustainability domain covered a relatively wide range from life-cycle assessment to different machinery evaluation. Discussions were active and gave chance for further enrichment of scientific dialogues. One of the key topics was the LCA (life-cycle assessment) procedures of different “hot spots” of agricultural technologies. Results were summarized for a tractor model, for maize silage production and a biogas plant (with different substrates). Other papers were introduced with numeric modeling of bioretention hydraulics in Cluj-Napoca (Romania) and the analyses of littering at river banks of Danube in Austria. Two papers were addressing monitoring of environmental processes: tree physiological disorders were identified as climate change indicators and fish tissues (gill, kidney, liver) have been used for monitoring heavy metal pollution content in fresh water (river Körös/Crisul). A promising report showed results on investigating changes of wool fiber’s physical properties (especially humidity uptake) in samples irradiated with electron beam. A group of researchers worked on analyzing homogeneity of bulk-blended fertilizers during different logistic activities and made suggestions to minimize segregation of components with different nutrition/chemical content. Another presentation reviewed results of a desktop research work on efficiency parameters of different biomass (straw, wood, pellets and coal) combustion devices (boilers) used in Poland. Unit prices of generating 1 kWh thermal energy were calculated applying a simple financial model. Poster presentations were discussing focus areas of low emission economy in Poland, Chinese cabbage production in ecologic farming (Romania), vibration effects on tribological tests, ecological aspects of solar collectors and main pests effecting energetic Salix clone production (Romania).
Both oral and poster presentations enjoyed good attendance among participants (10-20/session) which shows evidence of increasing interests towards different ecological aspects of sustainable agri-food technologies.
