“…Many previous studies have used the SWOT analysis as a screening tool in their research to carry out strategic planning. It seems that SWOT analysis is expanding over time into a widening field of applications, such as implementation of Industry 4.0 [47,51], renewable energy schemes [48,52], water management [53], strategies for economic sustainability [54], oil and gas industry [55], waste management [56], and solar power development [57]. One of the major drawbacks of this technique, however, is that the influence of each criterion in decision-making cannot be gauged quantitatively.…”

The emergence of Industry 4.0, also referred to as the fourth industrial revolution, has entirely transformed how the industry or business functions and evolves. It can be attributed to its broadening focus on automation, decentralization, system integration, cyber-physical systems, etc. Its implementation promises numerous benefits in terms of higher productivity, greater volatility, better control and streamlining of processes, accelerated enterprise growth, sustainable development, etc. Despite the worldwide recognition and realization of Industry 4.0, its holistic adoption is constrained by the requirements of specific skills among the workforce. The personnel are expected to acquire adaptive thinking, cognitive and computational skills, predominantly in the area of information technology, data analytics, etc. Thus, the universities that laid the foundation for future talents or trends in society have to adapt and modernize the existing programs, facilities, and infrastructure. This reshaping of higher education in consonance with the vision of Industry 4.0 possesses its opportunities and challenges. There are, of course, a multitude of factors involved and they need a reasonable assessment to strategically plan this metamorphosis. Therefore, this work aims to explore and analyze the different factors that influence the progression and enactment of Industry 4.0 in universities for sustainable education. For this purpose, a systematic approach based on a questionnaire as well as a SWOT (strengths (S), weaknesses (W), opportunities (O), and threats (T)) integrated with the analytic hierarchy process (AHP) is adopted. The questionnaires are administered to university employees and students (or stakeholders) to assess their viewpoint, as well as to estimate the priority values for individual factors to be included in SWOT. The AHP is implemented to quantify the different factors in terms of weights using a pairwise comparison matrix. Finally, the SWOT matrix is established depending on the questionnaire assessment and the AHP weights to figure out stakeholders’ perspectives, in addition to the needed strategic scheme. The SWOT implementation of this research proposes an aggressive approach for universities, where they must make full use of their strengths to take advantage of the emerging opportunities in Industry 4.0. The results also indicate that there are fundamental requirements for universities in Industry 4.0, including effective financial planning, skilled staff, increased industrial partnerships, advanced infrastructure, revised curricula, and insightful workshops. This investigation undoubtedly underlines the importance of practical expertise and the implementation of digital technologies at the university level to empower novices with the requisite skills and a competitive advantage for Industry 4.0.

“…A pragmatic approach is to charge a disposal fee according to the quantity of the total waste a household generates ( Paes et al., 2019 ). Since the cost of waste management is accompanied by economic benefits either savings through waste minimization or resource recovery through recycling, the unit-pricing approach represents an ideal option to charge waste generators for collection and disposal services based on its volume.…”

Over the past years, Indonesia, the world’s fourth most populous country, has confronted environmental problems due to uncontrolled generation of municipal solid waste (MSW). While the integrated solid waste management (ISWM) represents a critical strategy for Indonesia to control its production, it is also recognized that economic approaches also need to be promoted to address the waste problem concertedly. In this case study, empirical approaches are developed to understand how a volume-based waste fee could be incorporated into MSW collection services and how to apply a zero-waste approach in Indonesia by adapting resource recovery initiatives, adapted from Germany’s mature experiences in integrating the CE paradigm into the latter’s MSWM practices. Currently, Sukunan village (Yogyakarta, Indonesia) promotes waste reduction at sources in the framework of community-based solid waste management (CBSWM) by mobilizing the local community for waste separation (organic and non-organic) and waste recycling. As a result, about 0.2 million Mt of CO 2-eq emissions was avoided annually from local landfills. The economic benefits of recycling activities by the village’s community also resulted in 30% reduction of the waste generated. This CBSWM scheme not only saves the government budget on waste collection, transport and disposal, but also extends the lifetime of local landfills as the final disposal sites. By integrating the CE paradigm into its MSWM practices through the implementation of economic instruments and adherence to the rule of law in the same way as Germany does, Indonesia could make positive changes to its environmental policy and regulation of MSW. A sound MSWM in Indonesia could play important roles in promoting the effectiveness of urban development with resource recovery approaches to facilitate its transition towards a CE nationwide in the long-term.

An economic evaluation was conducted of flavanone and sugar production from orange peel (OP) using a sequential hydrothermal process. The process was conducted at laboratory (2 × 5 L), pilot (3 × 10 L), and industrial (3 × 500 L) scales. The results demonstrate that the scale‐up process decreased the cost of manufacturing (COM) with a significant increase in flavanone and sugar production. The lowest COM was of US$ 25.72/kg flavanones and US$ 1.43/kg sugars, both on an industrial scale. The predominant costs at the industrial scale (>90%) were the cost of utilities and the cost of raw materials. A low capital payback time was obtained, which decreased as return on investment and gross margin increased. A strengths, weaknesses, opportunities, and threats matrix demonstrates the relevant business topics related to the scale‐up of OP processing. Thus, the current scale‐up project can be considered as a promising approach to the production of flavanones and sugar from OP on an industrial scale. © 2020 Society of Industrial Chemistry and John Wiley & Sons Ltd
