In this paper, an assessment of the compound flood hazards in the city center of Rijeka due to the combined actions of the coastal and river flood sources was carried out, and hazard maps for the ...said area were prepared. Maps were created on a larger scale, taking into account various sources of flooding, and they show that the city of Rijeka has a high level of flood hazard, especially along the coastline and around the Rječina river where the highest flow velocities and water depths can be expected.
U ovome je radu provedena procjena opasnosti od složenih poplava u centru grada Rijeke uslijed kombiniranog djelovanja mora i rijeke te su izrađene karte opasnosti od složenih poplava za navedeno područje. Karte opasnosti od poplava izrađene su u krupnijem mjerilu uz uvažavanje različitih izvora poplava i potvrđuju kako riječko područje ima visoku razinu opasnosti od poplava, pogotovo uz samu obalu i oko korita rijeke Rječine gdje se mogu očekivati najveće brzine i dubine vode.
One of the major challenges in sustainable waste management in the agri-food industry following the "zero waste" model is the application of the circular economy strategy, including the development ...of innovative waste utilization techniques. The conversion of agri-food waste into carriers for the immobilization of enzymes is one such technique. Replacing chemical catalysts with immobilized enzymes (i.e., immobilized/heterogeneous biocatalysts) could help reduce the energy efficiency and environmental sustainability problems of existing chemically catalysed processes. On the other hand, the economics of the process strongly depend on the price of the immobilized enzyme. The conversion of agricultural and food wastes into low-cost enzyme carriers could lead to the development of immobilized enzymes with desirable operating characteristics and subsequently lower the price of immobilized enzymes for use in biocatalytic production. In this context, this review provides insight into the possibilities of reusing food industry wastes, namely, eggshells, coffee grounds, and brown onion skins, as carriers for lipase immobilization.
