Since start of the Industrial Revolution about 260 years ago, the negative effects from the traditional linear economy (LE) become threat to the stability of the economies and natural ecosystems. Strength of climate change, reduction of environment pollution and integrity of ecosystems are essential issues for survival of the global humanity. According to LE resources for production are easily available and unlimited, and after use wastes are disposable. The circular economy (CE) is an alternative to the LE where the resources may be used for as long as possible. It tries to capture the value of existing products and materials, and decreases the use of primary materials in industries. The CE is a part of environmental economics and beneficial to the society. It keeps products, components, and materials at their highest utility and maximum value at all times. At present CE is one of the most focused terms among environmental economic scientists. The aim of this study is the implementation of the sustainable development strategies and the transition from LE towards CE.

Abstract The never-ending exploitation of natural resources after the industrial revolution has caused irreversible damage to our environment and life. This vast resource deployment was expected to finally decelerate after the emergence of the Sustainable Development paradigm in the late 1980s. The concept of sustainable development aims to balance the tradeoff between supply and the needs of societies to also preserve the needs of future generations. Nonrenewable resources, especially water, have been at the heart of sustainable development goals. Sustainable Water Management (SWM) is an essential component of sustainable development. To achieve SWM, various water management challenges, in both developing and developed countries, should be addressed by attracting stakeholders to invest in water system efficiency and improvement projects, as well as by recycling and reusing water. To assess sustainable management policies and practices, evaluation of performance metrices – such as the Water Resources Sustainability Index, reliability, resiliency and vulnerability, and the Stability Index – is imperative. A cost-efficient policy should also facilitate the attainment of sustainability in all socioeconomic, and environmental sectors.

The humanitarian problem in the development of the industrial revolution 4.0 is very complex and is at the stage of worrying. No human being separated from the effect of the waves. High school is active users (user) of the results of the industrial revolution the 4.0. The problem that arises in the use of social media including the demise of expertise, the dissemination of hate speech and fabricated news. Teaching Islamic education material should be able to respond to this by providing normative information in the Qur'an and Hadith so that students can escape from its negative effects. One of the solutions offered was to integrate these materials with integratsi learning models in the themes that have been arranged in the school's learning policy. Integrating this material must through the phases between the awarding phase of learning, information or materials to grow a critical reason, generate hypotheses and generalities.

Growing consumerism and population worldwide raises concerns about society’s sustainability aspirations. This has led to calls for concerted efforts to shift from the linear economy to a circular economy (CE), which are gaining momentum globally. CE approaches lead to a zero-waste scenario of economic growth and sustainable development. These approaches are based on semi-scientific and empirical concepts with technologies enabling 3Rs (reduce, reuse, recycle) and 6Rs (reuse, recycle, redesign, remanufacture, reduce, recover). Studies estimate that the transition to a CE would save the world in excess of a trillion dollars annually while creating new jobs, business opportunities and economic growth. The emerging industrial revolution will enhance the symbiotic pursuit of new technologies and CE to transform extant production systems and business models for sustainability. This article examines the trends, availability and readiness of fourth industrial revolution (4IR or industry 4.0) technologies (for example, Internet of Things [IoT], artificial intelligence [AI] and nanotechnology) to support and promote CE transitions within the higher education institutional context. Furthermore, it elucidates the role of universities as living laboratories for experimenting the utility of industry 4.0 technologies in driving the shift towards CE futures. The article concludes that universities should play a pivotal role in engendering CE transitions.

AbstractThe implementation of circular economy in wood industries is an effective way for future sustainable development. The wood industries in China are not in the direction of circular economy approach due to less availability of assessment/calculation data of pollutants as per life cycle assessment (LCA) criteria. The present study focuses on the calculation of emission and pollutants from wood industries as per LCA; the emission and pollution data were collected from fiberboard Medium-density fiberboard (MDF), plywood and particleboard (PB) production. The comparative analysis of dust emissions, industrial waste gases and chemical oxygen demand (COD) were performed among three wood industries. The results revealed that the fiberboard industry was the highest emitter of dust, industrial waste gas and COD; and particleboard industry was the least emitter. Further, results indicated that pollutant index of wood industries were significantly changed between 2015 and 2017; the industrial waste water discharge increased five folds and the COD, dust and industrial gases increased two times. This study provides with the emission and pollutants data of wood industries as per LCA to promote the sustainable development for circular and low carbon economics.

There is a growing debate surrounding the contradiction between an unremitting increase in the use of resources and the search for environmental sustainability. Therefore, the concept of sustainable degrowth is emerging aiming to introduce in our societies new social values and new policies, capable of satisfying human requirements whilst reducing environmental impacts and consumption of resources. In this framework, circular economy strategies for food production and food loss and waste management systems, following the Sustainable Development Goals agenda, are being developed based on a search for circularity, but without setting limits to the continual increase in environmental impacts and resource use. This work presents a methodology for determining the percentage of degrowth needed in any food supply chain, by analyzing four scenarios in a life cycle assessment approach over time between 2020 and 2040. Results for the Spanish case study suggested a degrowth need of 26.8% in 2015 and 58.9% in 2040 in order to achieve compliance with the Paris Agreement targets, highlighting the reduction of meat and fish and seafood consumption as the most useful path.

Positive Effect

In a natural environment, plants usually interact with their neighbors predominantly through resource competition, allelopathy, and facilitation. The occurrence of the positive effect of allelopathy between peat mosses (Sphagnum L.) is rare, but it has been observed in a field experiment. It is unclear whether the stability of the water table level in peat induces positive vs. negative effects of allelopathy and how that is related to phenolic allelochemical production in Sphagnum. Based on field experiment data, we established a laboratory experiment with three neighborhood treatments to measure inter-specific interactions between Sphagnum angustifolium (Russ.) C. Jens and Sphagnum magellanicum Brid. We found that the two species were strongly suppressed by the allelopathic effects of each other. S. magellanicum allelopathically facilitated S. angustifolium in the field but inhibited it in the laboratory, and relative allelopathy intensity appeared to be positively related to the content of released phenolics. We conclude that the interaction type and intensity between plants are dependent on environmental conditions. The concentration of phenolics alone may not explain the type and relative intensity of allelopathy. Carefully designed combined field and laboratory experiments are necessary to reveal the mechanism of species interactions in natural communities.

The paper investigates primarily the geometrical meaning of the determinant of the Jacobian (det j) of the three connector lines of a planar in-parallel platform device using reciprocity. A remarkably simple result is deduced: The maximum value of det j namely, det jm is simply one-half of the sum of the lengths of the sides of the moving triangular platform. Further, this result is shown to be independent of the location of the fixed pivots in the base. A dimensionless ratio λ = |det j|/det jm is defined as the quality index (0 ≤ λ ≤ 1) and it is proposed here to use it to measure “closeness” to a singularity. An example which determines the optimal design by comparing different shaped moving platforms having the same det jm is given and demonstrates that the optimal shape is in fact an equilateral triangle

When adopting the zero waste strategy for the implementation of waste management measures at a Higher Education Institution, the commitment in the institution is of fundamental importance, not only with solid waste, but with the sustainability issue under a circular economy perspective, which should gradually be incorporated to the different programs and routine actions from universities. Several directions can be taken in the construction of this path so that universities are managed under the sustainability’s premises. In this article, the zero waste strategy for implementation of a circular economy program will be analyzed as a way to consolidate the process Green Campus. A qualitative and exploratory research was undertaken on green campus and zero waste strategies, mainly in universities. Although there is still a limited number of universities committed to zero waste actions, it was possible to appoint the benefits when implementing institutional programs related to sustainability and the fulfillment of the Sustainable Development Goals.

No one has the slightest doubt about the enormous potential that the African continent has as a tourist destination. The diversity of cultures, the great biodiversity that it possesses, the multiple artistic manifestations that it offers and the beauty of the seas that surround it are key pieces in continuing to promote its capacity as a tourist attraction, which is approximately 60 million tourists per year who generate seven percent of exports and employment. However, in order for Africa to take off, it is necessary that a number of conditions related to security, health, education, eradication of poverty, reduction of inequalities, peace and justice and quality of its waters, among others, are intimately related to the Sustainable Development Goals defined in the 2030 Agenda. In this context, we maintain that the implementation of the Circular Economy in Africa will be a key tool in this process of improving the sustainability of this continent in its three aspects, economic, social and environmental, and raising its level of tourism competitiveness.
