“…But for SO 4 2-, its high content might be contributed mostly by the sulfur content containing in the fuels (such as coke oven gas (COG) and coke breeze for igniting the burner). The above inference could be supported by Hu et al (2008). They estimated that ~90% of sulfur in the steel manufacturing process were derived from fuels.…”

This study measured the contents of the ionic and elemental constituents, and the chemical compounds containing in windbox (WB) dusts collected from a commercial iron ore sintering plant, then the results were used to identify possible PCDD/Fs formation pathways in the WB. We found that the abundance in both KCl and NaCl may provide a suitable condition for de novo synthesis of PCDD/Fs in the WB. Al, Fe, K, Ca, and Pb were the top five contents in WB16 dusts, but the co-existence of the above five metal contents warrants the need for further investigation on their roles in PCDD/F formation processes in the future. Although a low concentration of Cu was detected, it might be of importance to PCDD/Fs formation inside the WB. A total of 29 chemical compounds were identified. Among them, several oxygenated organic compound might be associated with PCDD/F formations at the beginning stage, but the roles of aromatic oxygenates on the formation of PCDD/Fs required further investigation. Finally, possible de novo synthesis pathways of PCDD/Fs were proposed based on the above findings. However, the above pathways are required further laboratory studies for validation before possible formation suppression approaches can be determined.

“…MEFA is increasingly applied in the fields of industrial ecology, environmental management and protection, resource management, and waste management. It is also used as a basis for life cycle assessment, eco-balance, environmental impacts strategies [12]. Recently the methodology has been applied to optimise material flows and waste streams in production processes in different countries [13], [14], [15], [16].…”

This paper briefly reviews the material and energy flows of the Malawian tea industry, in order to identify opportunities and reduce its environmental impacts. The review also details the concept and methodology as well as studies on applications of material and energy flow analysis. Environmental impacts are calculated with a life cycle assessment approach, using CML methodology. Results indicate that green leaf consumption in the studied factories ranged from 4.19 to 6.33 kg green leaf/kg made tea (MT), with an average of 4.96 kg per kg of made tea compared to 4.5 and 4.66 kg green leaf for tea factories in Kenya and Sri Lanka, respectively. Average wood consumption in Malawian tea factories is 3.35 kg/kg made tea and specific water consumption ranged from 1.92 to 8.32 kg/kg MT. In addition, the average value of greenhouse gas (GHG) emissions for eight factories is 4.32 kg of CO2-eq/kg MT as compared to 2.27 and 2.7 kg CO2-eq/kg in similar factories in Kenya and Sri Lanka, respectively. The major sources emitting GHG are from boiler fuel combustion and stand-by diesel power generation system. The study indicates that global warming has the highest environmental impact (88%), followed by acidification (6%) and eutrophication (2%), whereas human toxicity is lowest (<1%). The findings demonstrate how MEFA provides early recognition of environmental problems and how it can be used to establish priorities for improving operations in the existing factories.

“…The notion of MFA is based on the idea of optimizing within various industry sectors [7 ÷ 11]. Recently, much research is carried on concerning material flow in many branches, such as: ceramics [12], steel [13,14], automotive [1], environment and ecology [15 ÷ 19] at the regional and global level. MFA has become a useful tool, especially for industrial ecology (IE), to analyse the metabolism of social systems, such as countries and regions.…”

Original scientific paper Today, most contemporary organisations are facing many dilemmas, the essence of which is the determination of the ways of acquisition or maintenance of their position in the competitive environment. Companies have to continuously increase their economy. One of the ways to get competitive prevalence is analysis and optimization of material flow which contributes to the reduction of the company costs. Material flow in a production organization tells us a lot about how well the system is organised. The paper presents an analysis of the current state of material flow in a production company of the automotive branch. A project of the material flow optimization has also been proposed; the project consists of creation of a program of internal transport and optimization of the location of the working stands. The paper describes the current problems of the company internal transport and indicates solutions to those problems. Keywords: automotive industry; company logistics; material flow analysis; optimization; program of internal transport Optimizacija toka materijala -analiza slučaja u industriji motornih vozilaIzvorni znanstveni članak Danas je većina organizacija suočena s mnogim dilemama, bit kojih je određivanje načina postizanja ili održavanja stečenog položaja u konkurentnom okruženju. Poduzeća moraju neprestano povećavati svoju ekonomiju. Jedan od načina stjecanja nadmoći nad konkurencijom je analiza i optimizacija toka materijala, što doprinosi smanjenju troškova. Tok materijala u proizvodnoj organizaciji govori nam mnogo o organizaciji sustava. U radu se daje analiza postojećeg stanja toka materijala u jednoj proizvodnoj organizaciji motornih vozila. Predlaže se i projekt optimizacije toka materijala; projekt se sastoji od novog programa internog prijevoza i optimizacije položaja radnih štandova. U radu se opisuju postojeći problemi u internom prijevozu poduzeća i daju rješenja tih problema.
