This work systematically describes a laboratory study on different pretreatments of sugar cane straw to produce pozzolanic ash. Two procedures were used to accelerate the hydrolysis of celluloses and hemicelluloses and remove metallic impurities present in significant levels in sugar cane straw: hot water washing and acid leaching. Proximate analysis by thermogravimetry was carried out to cover volatile matter, fixed carbon, and ash content of the different straws. Detailed measurements of X-ray diffraction, oxide percentages, loss on ignition, and BET specific surface area were performed to compare hot water washed, acid leached, and nonpretreated ashes, after controlled processes of burning and grinding. The pozzolanic activity of the ashes was evaluated from the modified Chapelle and electrical conductivity methods. The results revealed that ashes with a high content of amorphous silica were produced, in spite of the straw pretreatments. However, both straw pretreatments induced a significant increase in pozzolanic activity, mainly associated with the removal of impurities, especially CaO, SO 3 , K 2 O, and carbon compounds. The effect of the hot water washing treatment was relatively small in relation to the acid leaching, but the hot washed ash was significantly more pozzolanic than non-treated ash.

“…S tim u vezi, Nasr i Thurston [3], Umeda i dr. [4] razmatrali su "dizajn za ponovnu proizvodnju", tj. reč je o tehnologiji koja je fokusirana na detaljnom dizajnu proizvoda kroz: rastavljanje·i ponovnu upotrebu za više životnih ciklusa.…”

“…Budući da su moduli fizički povezani jedni sa drugima, projektantu se daje mogućnost da realizuje različite kombinacije modula u formi novog proizvoda [4]. Dakle, arhitektura omogućava spajanje komponenti ili zabranjuje mešanje i usklađivanje komponenti [11].…”

UVODKupac dobija ulogu glavnog pokretača bitnih aktivnosti u održivom razvoju preduzeća. Promenom pravila ponašanja u poslovnom okruženju nameće se i potreba za novom poslovnom filozofijom.Hauschild i dr.[1] i Hart [2] ukazuju da u održi-vom razvoju preduzeća treba obratiti posebnu pažnju na organizaciju procesa proizvodnje kroz: smanjenje potrošnje energije i resursa, smanjenje emisije štetnih gasova, smanjenje upotrebe toksičnih materijala; upotrebu materijala dobrih karakteristika i kvaliteta, kao i mogućnost nadogradnje, popravke i reciklaže proizvoda.Takođe, danas je u upotrebi koncept "čistije proizvodnje". Koncept podrazumeva novi pristup proizvodnje bez ugrožavanja ljudskih života ili eko sistema. Čistija proizvodnja, predstavlja niz preventivnih postupaka u proizvodnji kako bi se smanjio nastanak otpada ili ograničila neefikasna upotrebe energije, vode i drugih resursa.Adresa autora: Miloš Vorkapić, Univerzitet u Beogradu, Institut za hemiju, tehnologiju i metalurgiju,

“…To avoid the infeasibility or suboptimal results in integrated optimization, some constrained modeling and optimization approaches were developed. For example, a product life cycle modularization approach based on self-organizing map and modular density concept [42], an eco-modular design method based structural redesign risk control [43], and a green modularization method involving the effectiveness of multiple life cycle phases [44].…”

Abstract-Recently environmentally conscious product design (ECPD) is highlighted by research community, because of the global conscious about low carbon emission and sustainable development. ECPD cares about the environmental, social and economic impacts of products during their life cycle phases, with the destination to achieve product life cycle design for sustainability. Furthermore, information and communication technologies are important for the implementation of computer-aided eco-design. The theories, methods, software tools about ECPD during 2005 to 2015 were reviewed in this work. Five most related aspects including product eco-design, design for disassembly (DFD), design for recycling (DFR), material selection (MS), and eco-design software tools were analyzed as related categories. Eco-impact assessment was found to be a pre-step in ECPD followed by product eco-innovation. DFD, DFR, and MS helped to improve the energy efficiency and eco-friendliness of products. Eco-design software tools are focusing on CAD-integration, web-based and knowledge base-based characteristics. More eco-design software tools will be developed in specific industries and to handling products with composite materials.Keywords-product eco-design; design for sustainability (D4S); eco-design software tools; state-of-the-art; eco-friendly produts
