Sustainable construction is hardly practised in Africa, despite the consistent campaign for its adoption. This study investigates the drivers and effects of sustainable construction in South Africa. The quantitative survey research design was adopted for the study and the respondents were the construction organisations in Johannesburg, South Africa. The study identified 17 significant drivers of sustainable construction, with construction cost as the dominant variable. The important environmental (8), economic (12), and social benefits (7) of sustainable construction were also determined. The challenges (24) of sustainable construction were also identified. The study recommended that measures for low construction cost should be put in place, and awareness campaigns should be enhanced. Economic benefits are still behind environmental benefits, and this could affect some prospective adopters. Lack of knowledge and weak economies were prevalent challenges that underscore the need for Western support for African nations to comfortably adopt sustainable construction.

Forest Carbon Sequestration

We examined the associations between social capital and rural households’ perceptions toward social, economic, and environmental benefits of forest carbon sequestration projects by employing the proportional odds model based on data collected from a rural household survey in Sichuan and Yunnan Provinces, China. Results revealed that: (i) households’ perceptions toward environmental benefits are more positive than their perceptions toward economic benefits and social benefits, and their perceptions toward economic benefits are more positive than their perceptions toward social benefits; (ii) households having a good relationship with village officials have higher odds of holding more positive perceptions toward social, economic, and environmental benefits of the projects; (iii) households which are members of local associations are more likely to have positive perceptions toward benefits of the projects; (iv) households whose members are more frequently involved in village-level public events are more likely to have more positive perceptions toward benefits of the projects; (v) households having more educated household heads have higher odds of holding better perceptions toward the benefits of FCS projects; and (vi) households of Yunnan Province are less likely to express positive perceptions toward benefits of the projects. Based on the research results, we concluded that social capital is significantly and positively associated with rural households’ perceptions toward benefits of forest carbon sequestration projects. Some policy implications are provided regarding how to make use of social capital elements to shape farmers’ perceptions toward benefits of the projects for the purpose of achieving a higher level of local acceptability for and sustainability of the projects.

Despite numerous studies on residential rainwater tank, studies on commercial rainwater tank are scarce. Corporate authorities pay little heed on this sustainable feature. With the aim of encouraging corporate authorities, this study presents the feasibility and economic benefits of rainwater harvesting (RWH) in commercial buildings in the capital city of Bangladesh, where water authority struggles to maintain town water supply. The analysis was conducted using a daily water balance model under three climate scenarios (wet, dry and normal year) for five commercial buildings having catchment areas varying from 315 to 776 m2 and the storage tank capacity varying from 100 to 600 m3. It was found that for a water demand of 30 L per capita per day (lpcd), about 11% to 19% and 16% to 26.80% of the annual water demand can be supplemented by rainwater harvesting under the normal year and wet year climate conditions, respectively. The payback periods are found to be very short, only 2.25 to 3.75 years and benefit–cost (B/C) ratios are more than 1.0, even for building having the smallest catchment area (i.e., 315 m2) and no significant overflow would occur during monsoon, which leads to both economic and environmental benefits. Though the findings cannot be translated to other cities as those are dependent on factors like water price, interest rate, rainfall amount and pattern, however other cities having significant rainfall amounts should conduct similar studies to expedite implementations of widescale rainwater harvesting.

Molybdenum Concentrate

Technical analysis was used to analyze the roasting of molybdenum concentrate on the basis of thermal balance test of rotary furnaces used for Roasting, and the results indicate that, on the condition of commercial production, the Roasting of MoS2 can occur spontaneously because the heat of reaction is so much that proper cooling measures should be adopted in case overheating happens. According to above analysis, carbon-free roasting technology of molybdenum concentrate was proposed in this paper. The results, which come from thermal balance test and technical analysis of rotary furnaces used for carbon-free roasting of molybdenum concentrate, indicate that outer heat source used in traditional Roasting technology is not needed in carbon-free roasting technology, because enough heat is generated during Roasting to ensure spontaneous reaction. In fact, heating is not needed in operating process except at the beginning, to make molybdenum concentrate catching fire, and when reaction completing, to remove residual sulphur. The technology in this paper is obviously advantageous in aspects of energy saving, output, quality of production, heat loss, the concentration of SO2 in flue gas, etc. and will have remarkable environmental benefits, economic benefits and social benefits.

Sport tourism is one of the fastest growing market segments in the tourism industry and is receiving increased attention for its social, environmental, and economic impacts upon destinations. Prior research in tourism impacts has tended to focus exclusively on tourism as a whole and does not differentiate among the different types of tourism that may be present in a destination. The purpose of this study was to examine how residents of Indianapolis, Indiana perceived the impacts sport tourism has upon their city. A total of 347 surveys were returned in a mailed questionnaire. Exploratory factor analysis revealed a four factor structure of social benefits, environmental benefits, economic benefits, and general negative impacts. Social and economic benefits were strong predictors for support for further sport tourism development revealing a strong identification with the advantages of sport tourism in their city such as an increased cultural identity and social interaction opportunities.

Starting Point

The aim of the manuscript was to present the collective results of research on the profitability of using various renewable sources in Poland with the greatest development potential. In the paper, the economic parameters of various investment projects were determined and calculated, i.e., Net Capital Value (NPV), Internal Rate of Return (IRR) and the Period of Return on Invested Capital (PBT). The economic assessment of the use of RES technologies was supplemented with the assessment of environmental benefits. The ecological criterion adopted in the study was the assessment of the potential and costs of reducing greenhouse gas emissions as a result of replacing fossil fuels with renewable energy technologies. On the basis of the constructed economic model to assess the profitability of investments, it has been shown that the analyzed projects will start to bring, depending on their type and technical specification, measurable economic benefits in the form of a reduction in the amount of energy purchased on an annual basis and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere. Moreover, the calculations show a high potential for the use of certain renewable sources in Poland, which contributes to the fulfillment of energy and emission obligations towards the EU. The analyzes and research of the Polish energy market with the use of the presented models have shown that the project is fully economically justified and will allow investors to make a rational decision on the appropriate selection of a specific renewable energy source for their investment. The presented economic models to assess the profitability of investments in renewable energy sources can be successfully used in other countries and can also be a starting point for a discussion about the direction of energy development. Due to the lack of collective, original and up-to-date research on the domestic market, the manuscript provides the reader with the necessary knowledge regarding the legitimacy of using renewable energy sources, investment and environmental profitability.
