Abstract Climatic and traffic effects are the causes of aging of the surface layer of asphalt, which leads to the necessary renovation of the latter. The use of waste from the tread layer provides a viable and beneficial solution for the environment and the economy. However, this solution must meet the requirement of sustainable development, which necessitates that a road has a very long lifespan. In this study we investigated the performance of recycled asphalt in terms of fatigue (as an element of life-cycle control). All the formulas were tested by the fatigue test in order to define the influence of the proportions of the asphalt aggregates, penetrability of the new binder used, and the manufacturing temperature. The results obtained showed the relationship between the contribution binder (reproduced between the new binder and the old binder) and the fatigue resistance under the influence of the parameters that we have mentioned above. At the end an optimization study has been carried in order to determine exactly the doses required to formulate recycled asphalt resisted to fatigue, the optimization seeks to maximize the asphalt aggregates and minimized the temperature of manufacture with a class of the binder compatible.

To achieve sustainable development, conserve energy and reduce emission are the themes of modern society. Life Cycle Design is an important design philosophy while Modular Design is one of the modern design ways which produced in the economic development. This paper presents a more perfect Modular Design based on Life Cycle Design. This paper will be developed in three parts: the first part introduces the basic concepts of the Life Cycle Design, Modular Design and the relationship between them; the second analyses the necessity of Modular Design in all stages of the product life cycle and the matter to be attended to; and third presents the method and steps of the Modular Design based on the Life Cycle Design and takes the design of range hood as an example in order to explain it.

This paper is carried out by conducting systematic mapping that focuses on the circular economy (CE) theme using bibliometric analysis. The purpose of this study is to provide a comprehensive view of circular economy research that is based on bibliometric data from 2017 to 2021. The data is collected from Scopus using VOSviewer software. Network visualization and density visualization are used in this study. The findings conclude that: (1) the publication trend of the circular economy continues to increase; and (2) the author with the most link is Mangla, S.K. with 15 links, and the author with the most research related to a circular economy is Liu, Y. with 16 papers/research. It is also found that there are 3 big themes that are close to a circular economy, namely sustainable development, recycling, and life cycle. This indicates that the opportunity to examine circular economy while associating it with variables outside of sustainable development, recycling, and the life cycle is still very large. The countries that have conducted the most research on circular economy is (1) United Kingdom (218 papers); (2) Italy (161 papers); and (3) China (161 papers).

The Relationship

The article deals with the problem of achieving sustainable development. The purpose of this study is to reveal the relationship between the components of sustainable development, taking into account the involvement of indigenous peoples in nature conservation. Climate change makes achieving sustainable development more difficult. Indigenous peoples are the first to feel the effects of climate change and play an important role in the environmental monitoring of their places of residence. The natural environment is the basis of life for indigenous peoples, and biological resources are the main source of food security. In the future, the importance of bioresources will increase, which is why economic development cannot be considered independently. It is assumed that the components of resilience are interrelated and influence each other. To identify this relationship, a model for the correlation of sustainable development components was developed. The model is based on the methods of correlation analysis and allows to determine the tightness of the relationship between economic development and its ecological footprint in the face of climate change. The correlation model was tested on the statistical materials of state reports on the environmental situation in the Khanty-Mansiysk Autonomous Okrug – Yugra. The approbation revealed a strong positive relationship between two components of sustainable development of the region: economy and ecology.

The Relationship

The relationship between people and the sea is weakening every year. We have conducted education for sustainable development (ESD) of the sea, aimed at deepening their understanding of the relationship between humans and the sea. We get method and we think that it can be a model to be implemented in other areas. The content of the lessons introduced on this occasion, we think that children were able to learn broadly about the ecosystem services of the sea, and became interested in the sea from many angles. we conducted more lessons, the willingness to take action by themselves has been nurtured.

This chapter explores the relationship between international development and global health. Contrary to the view that development implies ‘good change’, this chapter argues that the discourse of development masks the destructive and exploitative practices of wealthy countries at the expense of poorer ones. These practices, and the unregulated capitalist economic system that they are part of, have created massive inequalities between and within countries, and potentially catastrophic climate change. Both of these outcomes are detrimental to global health and the millennium development goals and sustainable development goals do not challenge these dynamics. While the Sustainable Development Goals acknowledge that inequality and climate change are serious threats to the future of humanity, they fail to address the economic system that created them. Notwithstanding, it is possible that the enormity and proximity of the threat posed by inequality and global warming will energise a counter movement to create what Kate Raworth terms ‘an ecologically safe and socially just space’ for the global population while there is still time.

Personal Assessment

The UN's sustainable development goals (SDGs), which aim to solve important economic, social, and environmental problems of humanity, are to be supported by education for sustainable development (ESD). Empirical studies on the success of the implementation of the SDGs in the field of education are still pending. For this reason, using the loss of global biodiversity as an example, this study examined the extent to which high school students, teacher trainees in biology, and biology bachelor students can identify the causes of the global biodiversity loss. A new questioning tool was developed and tested on 889 participants. In addition, the relationship between connection to nature and the personal assessment about biodiversity threats was examined. The factor analysis of the scale used showed that 11 out of 16 items were assigned to the intended factor. The comparison between high school students, teacher trainees in biology, and biology bachelor students showed no significant difference in overall assessment of the reasons for global biodiversity loss. When comparing the three risk levels in which the risk factors for biodiversity could be divided, across the three student groups, only minor differences were found. Therefore, a specific education of prospective teachers is necessary, as they have to pass on the competence as multipliers to their students. No significant difference could be found when examining the relationship between connection to nature and the overall scores of the assessment scale for the reasons of biodiversity loss. However, it was found that people who felt more connected to nature were more capable of assessing the main causes of risk for global biodiversity, while people who felt less connected to nature achieved better scores for the medium factors.
