Adopting Energy Policies of BRICS for South Africa
At its inception in 2006, there were four BRIC member countries comprising Brazil, Russia, India and China. In 2010, South Africa was invited to become a member of BRIC, which then evolved into BRICS, forming a new alliance of these five member countries. South Africa joined in December 2010 to promote peace, security, economic development and cooperation amongst these countries. The main objective was to contribute significantly to improving the socio-economic landscape of these five member countries, which have over three billion people. This is approximately 40% of the global population, and they account for approximately 25% of the world’s gross domestic product (GDP).

Disassembly Waste Generation
Disassembly waste generation forecasting is the foundation for determining disassembly waste treatment and process formulation and is also an important prerequisite for optimizing waste management. The prediction of disassembly waste generation is a complex process which is affected by potential time, environment, and economy characteristic variables. Uncertainty features, such as disassembly amount, disassembly component status, and workshop scheduling, play an important role in predicting the fluctuation of disassembly waste generation. We therefore focus on revealing the trend of waste generation in disassembly remanufacturing that faces significant influences of technology and economic changes to achieve circular industry sustainable development.

Nanoimpact in Plants
Transcriptomics studies are available to evaluate the potential toxicity of nanomaterials in plants, and many highlight their effect on stress-responsive genes. However, a comparative analysis of overall expression changes suggests a low impact on the transcriptome. Environmental challenges like pathogens, saline, or drought stress induce stronger transcriptional responses than nanoparticles. Clearly, plants did not have the chance to evolve specific gene regulation in response to novel nanomaterials; but they use common regulatory circuits with other stress responses.

Agricultural Green Development in China
Green development is a concept of sustainable development, aiming to protect the environment and ecosystems while meeting economic development needs. In the field of agriculture, green development has emerged as a crucial pathway for reconciling the conflicts between agricultural development and ecological conservation. Agricultural green development is a globally significant topic of concern, and as one of the world's largest agricultural countries, China's progress in this area holds substantial demonstration and reference value for global agricultural sustainability. To investigate the level of green development in Chinese agriculture, regional variations, and the evolutionary patterns, this paper is based on the framework of sustainable development theory.

Cereal Crop Residues in Green Concrete Technology
Concrete is mainly employed as a construction material. Due to the manufacturing of cement and the extent of concrete usage, numerous environmental issues and water suction have presented challenges. There is an immediate need to overcome these problematic issues by substituting natural resources with wastes and by-products of different biological processes in the production of concrete in order to make green concrete. Green concrete provides a relatively low-impact material to satisfy potential concrete demand and offers a cheaper, robust and highly reliable alternative that could fulfil future construction requirements in an environmentally safer way. Green concrete could be an alternative material that could replace those used in conventional methods of construction and help make a further step towards environmental sustainability and a circular bioeconomy.

Low-Carbon Logistics Capability
It is crucial to figure out how to achieve sustainable economic growth while fostering the growth of the logistics sector and the economy by expanding low-carbon logistics capability. The term "low-carbon logistics capacity" refers to a logistics operation's capacity to achieve sustainable development in the context of the needs of the low-carbon economy. Research and development capacity, economic development, energy consumption, and other considerations, have an impact on low-carbon logistics capability. Enhancing low-carbon logistics capability does not imply that the logistics sector should cut energy use and pursue a zealous reduction in carbon emissions; rather, it aims to improve the sector's energy use efficiency.

Reactions to Space Mining
There is currently a surge in interest from both private and government sectors in developing technology for mining asteroids and the moon (“space mining”). One of the key benefits highlighted by advocates of space mining is that it minimizes the usual problems associated with mining on earth in terms of pollution, environmental degradation, and encroachment on human habitats. Two studies—one conducted on a 27-nation sample (N = 4819), the other conducted in the U.S. (N = 607)—provide the first test of the assumed (but never studied) notion that space mining is more palatable to the public than terrestrial mining. Both studies indicate broad support for asteroid mining: levels of support were reliably above the mid-point, and much greater than for other forms of frontier mining such as mining the ocean floor, mining Antarctica, mining the Alaskan tundra, and lunar mining. Unlike terrestrial mining, community attitudes toward mining asteroids were largely non-ideological; support was not correlated with perceptions of ecological fragility, political ideology, or individualistic/hierarchical worldviews.

Effects of Organic Amendments on Solanum tuberosum L.
The potato (Solanum tuberosum L.) is the third most important food crop worldwide, after rice and wheat. The potato is one of the crops that produce more food per unit of time, water and area, even in more adverse climates in comparison with any other crop. It is also characterized by its extraordinary ability to adapt to different soil and climate conditions, occupying a leading role in the global food chain, and thus being considered by the United Nations Food and Agriculture Organization (FAO) as a food security crop. Likewise, the increase in world population leads to uncertainties in the food supply chain and it shows the need for high-yield crops.
