This paper presents a systems analysis perspective that extends the traditional process design framework to green process design, green energy and industrial ecology leading to sustainability. For green process design this involves starting the design decisions as early as chemical and material selection stage on one end, and managing and planning decisions at the other end. However, uncertaint...

globalization, increasing the global regulations of governmental and non-governmental organizations and customers’ request regarding to environmental compliance issues have led to organizations considering the green supply chain management to improve the environmental and economical performance. in order to maximize the efficiency of energy consumption and resources across the supply chain, gre...

in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

In this paper we examine an initial step towards Green Business Process Management. We give insights from a research project with the goal of monitoring and redesigning business processes in an environmentally sustainable manner. Using literature analysis and three case studies we derive suitable languages and software for business process modeling. In addition, we show business processes that ...

Objective(s): In recent years, the biosynthesis of gold nanoparticles has been the focus of interest because of their emerging application in a number of areas such as biomedicine. In the present study we report the extracellular biosynthesis of gold nanoparticles (AuNPs) by using a positive bacterium named Streptomyces fulvissimus isolate U from rice fields of Guilan Province, Iran.Materials a...

friedel–crafts synthesis of triarylmethanes over 3-methyl-1-sulfonicacid imidazolium tetrachloroaluminate under green conditions:in this work, friedel–crafts (fc) alkylation of various arenes with aromatic aldehydes catalyzed by 3-methyl-1-sulfonic acid imidazoliumtetrachloroaluminate {[msim]alcl4}, as a green catalyst, to prepare triarylmethanes (tams) has been carried out. some aromatic aldeh...

in this work, the ionic liquid triethylamine-bonded sulfonic acid {[et3n–so3h]cl}, n,n-diethyl-n-sulfoethanammonium chloride was used as a green acidic homogeneous catalyst to synthesis of 3,4-dihydropyrimidin-2(1h)-ones and 3,4-dihydropyrimidin-2(1h)-thiones as two categories of heterocycles, from aldehyde, dicarbonyl compound and urea or thiourea throughout the one-pot three components cycloc...

silver nano-particles have different biological applications due to their compatibility. chemical methodsusually result in remaining some amounts of toxic reactions on the nano-particles. for this reason, the useof plants as sustainable and accessible resources in preparation of compatible nano-particles has attracteda lot of attention in the recent years. this research investigated the green s...
