“…The factor that greatly affects NCV is moisture, and this is shown in summer months where the greatest reduction in NCV value is observed. As presented by Montejo et al (2011), the found NCV can be comparable with the MSW analyses, on as received basis. Net calorific value is considered an economical indicator, and the classification according to CEN 343 is class 4.…”

“…This indicates that the produced RDF has significantly higher moisture content than other RDF samples studied. (Liu et al 2001;Wan et al 2008;Montejo et al 2011) More specifically, from the pre-drying procedure followed for all of the increments of each sample, moisture was found to be more than 32 % in the majority of the samples. The maximum moisture found in a daily increment was 47.57 %, and the minimum was 31.60 %.…”

Refuse-derived fuels (RDF) are a category of alternative fuels produced as byproducts from the process of waste management plants. RDF can be utilized for heat and power production, contributing to the waste hierarchy set by European Union. However, the need for standardization of RDF becomes gradually important in SouthEastern Europe, where the market for waste recovered fuels is under development. The application of certification and quality management schemes in the waste treatment and fuel production processes, along with the use of a new terminology, solid recovered fuels may enhance public acceptance and promote the thermal utilization of this resource in industrial facilities. In the present work, a sampling and analysis campaign of RDF produced at a mechanical and biological treatment facility in Athens, Greece, took place. The sampling and analysis were carried out according to the standards of CEN/TC 343. The sampling period lasted 1 year, resulting in 20 samples. Proximate, ultimate analysis, chlorine and heavy metals' content were carried out. Furthermore, a technical and economic assessment was carried out, in order to propose realistic solutions for the improvement of the produced RDF quality and the plants' viability. Two sets of scenarios are assessed with techno-economic criteria referring to different technical solutions. At the end of the study, a step-by-step approach is proposed, which may guarantee the economic feasibility of the proposed plant retrofitting project and a pay-back period adjusted to the extent of the retrofitting measures to be decided.

“…In the past, the MSW has mainly been deposited on the landfills.Because of its simplicity, such disposal has a low price, but it is contrary to the order of hierarchy of waste disposal [9,10] and the previously mentioned EU waste management directives and documents. MSW contains mostly organic, biodegradable fraction which occupies 55 % of the total amount of waste [8].…”

Within the RDF fraction dominate the components such as paper, plastic, etc.…”

Subject rewiewMechanical Biological Treatment (MBT) of waste represents a series of mechanical and biological processes which have the purpose to reduce the amount of waste that is placed on a landfill. In accordance to the 'hierarchy of waste' defined by the EU Waste Framework Directive, waste disposal to landfill represents the least desirable option.Considering the MBT process, the input component is a Municipal Solid Waste (MSW) and output components consist of Refuse Derived Fuel (RDF), compost and possibly the materials suitable for recycling.The quality of output components depends on the input waste composition.More efficient primary waste separation decreases capacity and complexity of MBT facilities.RDF offers possibility of energy recovery from the part of such separated fractions.MBT technology does not solve the problem of harmful substances residual in MSW narrowing the application of compost obtained by the biological treatment and requiring additional treatment of flue gases from RDF combustion. Comparison of the composition of untreated MSW and RDF obtained by the MBT process is also presented in the paper. Keywords: compost; MBT; RDF/SRF; waste hierarchy Fleksibilnost MBO postrojenjaPregledni članak Mehaničko biološka obrada otpada (MBO) predstavlja niz mehaničkih i bioloških postupaka koji imaju za svrhu smanjiti količinu otpada koji se odlaže na odlagalište što prema "hijerarhiji otpada" definiranoj Direktivom o otpadu (Waste Framework Directive) Europske Unije predstavlja najmanje poželjnu opciju zbrinjavanja otpada. Ulazna komponenta u MBO proces je kruti komunalni otpad (MSW), a izlazne komponente čine RDF gorivo, kompost i eventualno materijali pogodni za recikliranje. Kvaliteta izlaznih komponenti ovisi o ulaznom sastavu otpada. Učinkovito primarno razdvajanje otpada smanjuje potrebu za MBO kapacitetima. RDF nudi mogućnost energetske oporabe dijela izdvojenih frakcija. MBO tehnologije ne rješavaju problem štetnih tvari zaostalih u MSW, koje sužavaju primjenu komposta dobivenog biološkom obradom, a kod spaljivanja RDF-a zahtijevaju dodatne postupke obrade dimnih plinova. U radu je dana usporedba sastava neobrađenog MSW-a i RDF-a dobivenog odabranim MBO postupkom.

A novel educational methodology, Implementation of Mathematical, Experimental, and Computer‐based Education (IMECE), where its name was derived from the letters of the word “imece” (a Turkish tradition) by taking into account the integrative meaning of this cultural concept, was proposed to explore the synergistic effect of the conventional mathematical solution procedure, visual application, and MATLAB‐based simulation on the perceptions and learning quality of the engineering students. Within the scope the present research carried out both at the state university (undergraduate and graduate levels) and at the foundation university (undergraduate level), water discharge problem (a special case of the Bernoulli's principle/Toricelli's law) was chosen as an example application. In the study, the experimental results of three different tank models (vertical cylindrical, conical, and spherical) and the solution algorithms written in MATLAB were presented in detail, and new empirical equations were also developed for each laboratory scale system depending on the experimental data. The effectiveness of the proposed IMECE method was evaluated statistically within the framework of both “Student Survey” and “Student Assessment” conducted with the participation of 84 students. Based on the mean scores obtained for all participating students, the results of the statistical tests indicated that the quantitative performance (or effectiveness) of the applied IMECE methodology was determined as 97.73%, 67.36%, and 82.55% for the perception/satisfaction section, the learning section, and the overall evaluation category, respectively.

Abstract: ABSTRACTcalorific value (similar to that for some types of wood) corresponds to RDF, so its incineration will be more profitable than using MSW as fuel.
