Nuclear power (NP) remains one of the choices for increasing environmental and social concerns related to energy needs due to its relatively low level of emissions. At the other hand, serious problems can arise as a result of potential accidents. For example, the nuclear power plant (NPP) crisis in Fukushima Daichi (2011) has caused a great deal of concern not only for the Japanese people, but also for the world. Today, the consequences of this occasion continue in EU countries. However, Serbia does not have an NP plant on its own, it has about 15 NP stations around it. The Serbian Government, therefore, wanted to know what the majority of its people think about nuclear energy (NE) and possible consistency. The objective of this paper is to present the results of the Serbian population assessment of the NP risk perception of the trial. A series of 270 face-to-face interviews took place in the public square of Belgrade in March 2019. A logistic regression analysis was used to examine the cumulative effects of the different risk factors. As a key result, it was found that almost all respondents did not support the construction of the NP in Serbia. In addition, this research identified several important variables that have a significant impact on the perception of the public risk of NP.

Bio plastic plastic is an innovative and emerging industry that brings hope as well as ambiguity from materials sourcing to end life management. Circular economy (CE) is to decouple economic growth from a carbon footprint and maximum utilization of renewable resources that keep creating pressure on emerging bio-based or bio-plastic industry to save our planet from the adverse effect of traditional plastic industry. Through the article, bio plastic circular value chain and a flow chart have been developed to understand, how circularity works in the value chain and stimulate competitiveness, and necessity of practicing circular economy concept in the bioplastic industry. The research has been conducted by mini literature review, information and knowledge gain from stakeholder’s publications, website, books, case study as well as direct and indirect involvement in bio-plastic industry. We observed bio plastic industry also needs to practice circularity in the value chain that will ensure more competitiveness and gain sustainability leadership index.

There are questionnaire data. Questionnaire data were paper-based data. Figure 1 shows own calculations using questionnaire data, Figure 1 can be published.

This paper explores politics on the consumer side and how they shape the electricity market within the Nigerian context. Using mixed method approach, quantitative data from news reports and government records, together with informal interviews of some targeted energy consumers were used to gain understanding on the motives of political consumption in Nigeria's electricity sector. The study reveals that there are four salient energy consumer groups in Nigeria categorized based on their willingness-to-pay and ability-to-pay for electricity bills. The study further reveals the origins and evolution of unwillingness-to-pay for electricity by certain consumer groups and their impact on the workings and development of the Nigerian electricity market. The study concludes by stressing the importance of value-added services by energy businesses as a way to start to engage with customers which leads to the establishment of trust and a gradual transition to a customer-driven energy future.

This study examined the flow of selected resources in Sorsogon City using the urban metabolism approach. The resources analyzed were water, energy, food, and construction materials. These were chosen using a toolkit provided by the United Nations Environment (formerly the United Nations Environment Programme), which funded the study. Primary data were gathered through key informant interviews and a focus group discussion with individuals knowledgeable on the four resources studied. Secondary data were obtained from the Sorsogon City Hall, other government offices, and private organizations. The documents and the responses of the study participants were used in the analysis. Findings showed that the Sorsogon City Water District’s production volume for the next 10 years is sufficient to meet the needs of the growing population. However, this does not consider the areas not serviced by the water utility—which is half of all the barangays in the city. Meanwhile, if the present population growth and energy utilization rate remains the same, Sorsogon City will need to increase its electricity and liquid fuel imports. This is because all power used in the city is imported. Similarly, if Sorsogon City does not adopt any changes in its rice production scheme (i.e., no change in annual yield and production area), it will need to increase imports to supply the growing demand. Likewise, since the city has no local source of construction materials, it will continue to be a net importer of steel, cement, sand, and aggregates. Based on these results, several recommendations were made by the researchers for the consideration of Sorsogon City officials.

The recent development of nanoscale fillers, such as carbon nanotube, graphene, and nanocellulose, allows the functionality of polymer nanocomposites to be controlled and enhanced. However, conventional synthesis methods of polymer nanocomposites cannot maximise the reinforcement of these nanofillers at high filler content. Approaches to the synthesis of high content filler polymer nanocomposites are suggested to facilitate future applications. The fabrication methods address design of the polymer nanocomposite architecture, which encompass one, two, and three dimensional morphology. Factors that hamper the reinforcement of nanostructures, such as alignment, dispersion of filler as well as interfacial bonding between filler and polymer are outlined. Using suitable approaches, maximum potential reinforcement of nanoscale filler can be anticipated without limitations in orientation, dispersion, and the integrity of the filler particle-matrix interface. High filler content polymer composites containing emerging materials such as 2D transition metal carbides, nitrides, and carbonitrides (MXenes) are expected in the future.

There are geographical and questionnaire data. Questionnaire data were paper-based data. Geographical data were mainly provided by Openstreemap (www.openstreemap.org).

This study addresses the challenge of disappearing green space within the Federal Capital City (FCC) of Nigeria. The study investigates the multiplicity of factors which contribute to the disappearance of the green spaces and conclusively suggests an approach to conserving the green spaces with the surging urbanization in view.
