Rubber is one of the rare materials that can be used in many sectors and for multiple purposes. It can be used in a wide range of frameworks, from very simple coating materials to very complex spacecraft parts. Apart from natural rubber, compounds are also used for different purposes in rubber production. For a product with such a wide range of uses, the sustainability of its compounds is particularly important. The objective of this study is to investigate environmentally friendly and sustainable alternatives for rubber and some compounds, such as fillers and softeners. By doing this research with an academic method, the most suitable option is determined by taking the weights of the factors affecting this decision into consideration. As a result, the most suitable rubber, filler, and softener options are presented.

Environmental impact assessment comprises a set of analyses, and there are several subjects. However, the “airport impact research” subject has grown into a more integral and broader view. Green airports make this phenomenon more complex when analyzing different operational criteria. This study focused on easing the readers’ understanding of the impact analysis phenomenon more comprehensively. Moreover, the motivation behind this paper is to express the roots of the research subject on the green airport concept. Three domains are defined to classify the impact analysis, affecting each other while focusing on operational or capital investments in the airports. Spending a budget or an organizational function might negatively affect carbon dioxide emissions or further toxic disseminating natural resources. This study has examined 93 published scientific papers to show the distribution of the classified subjects on the three domains as Energy, Natural resources, and economic sustainability. Despite the common superiority of environmental topics, it has been seen that economic efficiency and the importance of the design subjects are the main predecessors in this review. Subjects have diverted into the environmental issues in the later years. Also, popular keywords have been presented to the audience’s attention, which counts the frequency in time.
