AB  - Wood–plastic composites (WPCs) are some of the most common modern composite materials for interior and exterior design that combine natural waste wood properties and the molding possibility of a thermoplastic polymer binder. The addition of reinforcing elements, binding agents, pigments, and coatings, as well as changes to the microstructure and composition, can all affect the quality of WPCs for particular purposes. To improve the properties, hybrid composite panels of WPCs with 30 wt. % and 40 wt. % of wood content and reinforced with one or three metal grid layers were prepared sequentially by extrusion and hot pressure molding. The results show an average 20% higher moisture absorption for composites with higher wood content. A high impact test (HIT) revealed that the absorbed energy of deformation increased with the number of metal grid layers, regardless of the wood content, around two times for all samples before water immersion and around ten times after water absorption. Also, absorbed energy increases with raised wood content, which is most pronounced in three-metal-grid samples, from 21 J to 26 J (before swelling) and from 15 J to 24 J (after swelling). Flexural tests follow the trends observed by HIT, indicating around 65% higher strength for samples with three metal grid layers vs. samples without a metal grid before water immersion and around 80% higher strength for samples with three metal grid layers vs. samples without a grid after water absorption. The synthesis route, double reinforcing (wood and metal), applied methods of characterization, and optimization according to the obtained results provide a WPC with improved mechanical properties ready for an outdoor purpose.

AB  - Fossil fuels are widely used to provide energy in major industrial sectors, while consumption of
fossil fuel leads to undesirable increases in greenhouse gas emissions, causing climate changes.
Because of it is important to use energy in more efficient way in order to reduce theneedofusing
fossil fuel. Heat recovery and reuse of waste heat is a promising approach to increase energy
efficiency, saving energy whichleadstoreduceddemands for fossil fuels.
The goal of this study is to minimize the fuel consumption by maximizing energy efficiency via
indirect heat integration of multiple processes in an industrial zone. Theproposedmodel is
applied on a case study, which consists of multiple plants,served by a centralized
utilitysystem,which provides required heat and power for processes.Theadvantage of the used
model is simplicity and its linear programming formulation (LP).
AB  - Fosilna goriva imaju veliku ulogu u obezbeđivanju potrebne energije u većini industrijskih sektora.
Potrošnja fosilnih goriva dovodi do neželjenog povećanja emisije gasova staklene bašte,
koji uzrokuju klimatske promene.Zbog potrebe da se smanji potrošnja fosilnih goriva,
rekuperacija otpadne toplote je pristup koji obećava povećanje energetske efikasnoti, jer se
energija štedi, što dovodi do manjih zahteva za potrošnju fosilnih goriva. Cilj ove studije je svođenje upotrebe fosilnih goriva na minimum, time što se
maksimizuje energetska efikasnost kroz indirektnu toplotnu integraciju. Predloženi model
toplotne integracije je primenjen na case studiju, kojapredstavlja industrijsku zonu sa više postrojenja.
Predpostavlja se da se industrijaska zona snabdeva centralizovani mutiliti sistemom,
koji obezbeđuje potrebnu količinu toplote i energije za sve procese. Prednost korišćenog modela je
jednostavnost i linearnost programske formulacije (LP programiranje).
