Treatment and valorization plants in materials recovery supply chain

Aim of industrial symbiosis is to create synergies between industries in order to exchange resources (by-products, water and energy) through geographic proximity and collaboration [1]. By optimizing resource flows in a “whole-system approach”, a minimization of dangerous emissions and of supply needs can be achieved. Resources exchanges are established to facilitate recycling and re-use of industrial waste using a commercial vehicle. Several paths can be identified in order to establish an industrial symbiosis network (Figure 1, left), in relation (i) to the life cycle phase (raw material, component, product) and (ii) to the nature (material, water, energy) of the resource flows to be exchanged. Sometimes by-products and/or waste of an industrial process have to be treated and valorized in order to become the raw materials for others. In particular, two main treatment processes can be identified: refurbishment/upgrade for re-use (Figure 1, center) and recycling for material recovery (Figure 1, right). A brief overview of technological and economic aspects is given, together with their relevance to industrial symbiosis

Online community portals for small businesses

M.A.The first part of the study is a literature review which indicate that small, medium and micro enterprises (SMMEs) represent an important vehicle to address the challenges of job creation, economic growth and equity. Modern economy is driven by innovations and knowledge. Transforming information resources into knowledge and maximise the value of knowledge is the new challenge in achieving a sustainable competitive advantage. Information resources are needed by small businesses as much as their larger counter parts but small businesses are usually in a disadvantaged position in terms of finance and expertise. Information and communication technologies (ICTs) offer small businesses new opportunities in the information economy. Exciting ICT applications such as Web portals provide platforms for business communities to share information and communicate more efficiently than ever. Such information resources enable small businesses to react faster and adapt better to the changing global market. The stimulation of SMMEs must be seen as part of an integrated strategy to develop the society to a higher level. The research findings of this study provide all stakeholders in small business development in South Africa including government, industries and academics a better understanding and practical guideline for delivering information resources to small business owners and managers and the design of information portals that can address the information needs of small businesses in South Africa. The empirical components that follow the literature review comprised a questionnaire survey. The survey focused on non-franchised small businesses in the retail industry in the greater Johannesburg metropolitan. A total of 150 questionnaires completed by small business owners and managers were used for statistic analysis in this research. The questionnaire consisted of four sections: business biographic information, business information and agencies, information and communication technologies usage, and community and portal activities. The survey results revealed valuable insights and trends in the use of ICTs and attitudes towards information sharing amongst small business owners and managers. Textile, clothing, footwear and leather goods were the most popular trade for the small businesses use in the survey. Nearly all respondents prefer English for business communication and the businesses are typically owner manager with a small number of employees. Infrastructure for ICTs is in place for small businesses, but the usage level is still basic. Short message service (SMS) and e-mail are the most commonly used ICT tools. Traditional media such as television, radio, newspapers and magazines remain the most important source of information for these small business owners and managers. Younger businesses adapt better to ICTs than the older businesses. Despite a mixed attitude towards sharing business information, small business owners and managers showed a high level of interest in networking with other businesses, in particular with potential customers and suppliers. Most respondents do not belong to any professional or industrial organisation primarily because they were not aware of these organisations. Based on the literature review and the empirical research, the final conclusion that was made from this research is that Web community information portals can, to a great extent, promote the use of information resources for small businesses in South Africa. The results from this research give a better understanding and are useful guidelines to stakeholders in small business development in South Africa

Semantic adaptability for the systems interoperability

In the current global and competitive business context, it is essential that enterprises adapt their knowledge resources in order to smoothly interact and collaborate with others. However, due to the existent multiculturalism of people and enterprises, there are different representation views of business processes or products, even inside a same domain. Consequently, one of the main problems found in the interoperability between enterprise systems and applications is related to semantics. The integration and sharing of enterprises knowledge to build a common lexicon, plays an important role to the semantic adaptability of the information systems. The author proposes a framework to support the development of systems to manage dynamic semantic adaptability resolution. It allows different organisations to participate in a common knowledge base building, letting at the same time maintain their own views of the domain, without compromising the integration between them. Thus, systems are able to be aware of new knowledge, and have the capacity to learn from it and to manage its semantic interoperability in a dynamic and adaptable way. The author endorses the vision that in the near future, the semantic adaptability skills of the enterprise systems will be the booster to enterprises collaboration and the appearance of new business opportunities

INDUSTRY 4.0 – CHALLENGE TO HUMAN RESOURCES

The report examines the key role of human resources in implementing the digital transformation of business processes in Bulgarian industrial enterprises. The survey was conducted in fifty-eight industrial enterprises in Bulgaria; the participants in the study were 232 HR managers and specialists. The main method of research is the questionnaire and the paper contains the results of the analysis of this questionnair

Impacts of the implementation of Industry´s 4.0 technologies in the portuguese footwear industry

The first three industrial revolutions came about as a result of mechanization, electricity and IT. It is safe to state that a fourth revolution is currently taking place in manufacturing, with it being generally branded as Industry 4.0. These Cyber-Physical Systems comprise smart machines, storage systems and production facilities capable of autonomously exchanging information, triggering actions and controlling each other independently. The present investigation takes this premise into account and focuses in pursuing what are the main implications of the implementation of Industry´s 4.0 technologies in the Portuguese Footwear Industry. In order to lay the foundations for the study, an extensive literature review was executed. This was followed by a qualitative and exploratory investigation, based on twelve interviews with various relevant actors of the Portuguese footwear scene. The interviews resulted in insightful conclusions. Firstly, it is possible to notice that the Portuguese Footwear industry is generally well equipped and informed. Generally, the manufacturers are aware of the new technologies that are made available, being that there are already successful examples of companies using them. The study has highlighted the importance for companies to develop an extensive evaluation regarding their specific needs in order to better decide in which technologies to invest. The path is being designed in order to continuously simplify technologies, so that they are easier to work with. The main constraint, to the present day, is linked with finding skilled workforce to perform tasks at the shop floor level and also with the generation of enough value that allows the manufacturers to invest in more advanced technology
