Nowadays, numerous processes of any supply chain are done by suppliers and consequently they cause a massive amount of pollution released to the nature. Hence, greening the suppliers has become a necessity. Although most of green supplier development programs need high investment, formal optimization models that address this issue are very rare. This paper mainly aims to address this prob...

Increasing global notices in environmental protection, green supply chain management (GSCM) has received much attention by researchers and managers more than the past. Commonly, firms have considered cost criteria to select their suppliers. Despite the fact that there are various papers considering the formal criteria in supplier selection, there is a few limited numbers considering the environ...

Ionic liquids (ILs) have been considered as “green solvents” in many published works. However, recent research on their eco-toxicity and degradability has proven that some ILs are not as “green” as expected. In this review, the greenness of ILs was discussed in terms of their synthesis, eco-toxicity and degradability and their applications. Greenness of ILs depends not only on themselves but al...

Green building design is a socio-technical process, so it is important to engage end users (e.g. building occupants) in requirements gathering. Given that a majority of software tools used in designing green buildings are aimed at engineers, we must determine the most effective way of communicating information about energy use requirements to end users, who are typically unfamiliar with energy ...
