Purpose – This study was conducted to determine the effect of peel of Arabica coffee (PAC) with Win Prob Probiotic on crude fiber content and fiber fraction (neutral detergent fiber, NDF; acid detergent fiber, ADF; cellulose; hemicelluloses; and lignin). The hypothesis of this study is that PAC fermentation using Probiotic Win Prob can decrease the content of crude fiber and fiber fraction.

Design/Methodology/Approach – The research design applied was a factorial completely randomized design with three treatments and three replications. Factor A (probiotic dose) consisted of three doses: 2.5%, 5%, and 7%, in addition, there are three fermentation durations considered as factor B, which are 20, 30, and 40 days.

Findings – The result of this study indicates that the content of crude fiber and fiber fractions can decrease each amount of the variable of this study. The best treatment was obtained in A3B3 with 7% probiotic with 30 days of fermentation. Rough fiber PAC decreased up to 27.66% and NDF content decreased by 3.6%. Moreover, ADF content decreased up to 4.10%. The last lignin decreased by 18.75%.

Research Limitations/Implications – Only a small portion of coarse fiber and fiber fractions in PAC is fermented with Win Prob probiotics. So we can try other ways to reduce the coarse fiber and PAC fiber fractions such as the combination of ammonium and fermentation (amofer).

Originality/Value – The PAC has a high content of crude fiber and fiber fractions (NDF, ADF, cellulose, hemisellulose, and lignin), and so it is recommended as ruminants for feed ingredients.

Composites based on fiber are commonly used in high-performance building materials. The composites mostly use petrochemically derived fibers like polyester and e-glass, due to their advantageous material features like high stiffness and strength. All the same, these fibers also have important shortcomings related to energy consumption, recyclability, initial processing expense, resulting health hazards, and sustainability. Increasing environmental awareness and new sustainable building technologies are driving the research, development, and usage of “green” building materials, especially the development of biomaterials.

In this chapter, the natural fiber evaluation approach is applied, which covers a diverse set of criteria. Consequently, the comparative assessment of diverse natural fiber types is applied through the use of an expert decision system approach. The best performing fiber choice is made by comparatively evaluating the materials related to green building. The proposed fiber can be used and applied by green building material manufacturing companies in various countries or locations as a reference when selecting the fiber with the best performance.

We review the conceptualization of quality of life (QOL) past and present, providing a new definition that transcends the traditional approach. We discuss the importance of QOL as a mandatory assessment in patient care and clinical trials, concurring with the need for disease-specific tools and focusing on a nerve fiber-specific tool for assessing impacts of diabetic neuropathies on QOL and activities of daily living (ADLs) used in multi-center clinical trials and translated into different languages. By relating neuropathic disabilities to different nerve fibers, the Norfolk Quality of Life – Diabetic Neuropathy (QOL-DN) is able to measure impacts of nerve-fiber-specific neurotrophic therapies, providing pertinent endpoints to changes in health status and QOL.

The expansion of connectivity on a national scale in Brazil, whether through mobile Internet or fixed broadband, is described as one of the factors that can lead to social and economic benefits for large parts of the population who do not have a network connection. It can also help to reduce poverty by improving the infrastructure of services and increasing Internet use for education purposes. It also provides people with the ability to communicate with online administrative services – local, regional, and national. In Brazil, the main difficulty facing an effective universalization of telecommunications has been limitations in accessing services. This chapter demonstrates the relevance of small Internet providers for the expansion of fixed broadband in less commercially attractive regions (in terms of subscribers, income, and distance) who have been growing over recent years and are now present in 70% of Brazilian municipalities and whose role is paramount to reducing the digital divide.

System change for the circular economy (CE) in the society requires innovative thinking in refining existing material into new resources and collaboration with different actors. We introduce examples of decomposers with different roles in a circular ecosystem. Examples from reusers of waste material, users of recycled materials, designers of new technologies, and facilitators of CE networks are introduced to illustrate how companies contribute to a circular ecosystem in the clothing and textiles industry. Moreover, we illustrate the networked nature of supply chains of circular materials.

Strategic Management, Business Ethics.

This case is suitable to be used in advanced undergraduate and MBA/MSc level.

The case accentuates the challenges faced by Geetanjali Woollens in its mechanical recycling business which is proving detrimental to its African business expansion plans. The case is developed from the episodes of divergence in January 2018 when the buyers’ non-acceptance of mechanically recycled products initiated a managerial dilemma between “business sustenance” and “sustainable business” for Geetanjali Woollens. Being associated with the recycling business for more than 25 years, Madhukar Ghosh, the General Manager at Geetanjali Woollen recycling unit, was delving upon practical, supply-chain-wide solutions to generate standard acceptance norms for mechanically recycled textiles. For him, ethical purpose of business existence was equally important as the profit motive. Bringing operational clarity and standardized regulatory framework still seemed a big challenge for international policymakers and torchbearers of environmental responsibility, and Governments and NGOs popularizing green initiatives. Lack of policy guidelines for business behavior was exacerbating the business functioning. Madhukar knew that consistent buyer policies and standard regulatory framework could clear some mist and induce maturity in the concept of circular economy. Some formalizations were expected till the end of December 2018, if the deadlines did not get pushed further.

The objectives of this case are as follows:

• to highlight the limitations that recycled apparel and textile products have and the concerns that emerge for buyers, designers, and consumers, due to these limitations;

• to highlight the myopic business vision with which the recycling business is suffering due to the lack of a formalized regulatory framework, which in turn is creating various system barriers and making recycling business an unattractive proposition;

• to appreciate the contribution of mechanical recycling of post-consumer textile waste as a closed-loop manufacturing technique in recouping the eco-impacts of increased disposal of apparel and textile products; and

• to promote discussions for innovative solutions for limitations and concerns related to substances of concern in the recycling business and deliberations for a more effective tracking of such substances to facilitate buyer acceptance of mechanically recycled products.

This chapter shows how different recycling locations influence closed-loop supply chain (CLSC) cost and carbon dioxide equivalents (CO₂e), as well as reveal competitive recycling and manufacturing locations, including relevant distance- and location-related factors, for achieving very low cost and CO₂e CLSCs supporting circular economy. Exploratory data analysis is used to analyze results from simulations based on empirical data and market rates relating to textile and clothing CLSCs. The results show that most very low-cost and CO₂e CLSCs consist of fabric and garment manufacturing located at the same or nearby locations, and whose labor costs and electricity CO₂e are low, whether fiber recycling facilities are located in proximity to used garment sorting facilities or not. Scenario and sensitivity analyses of important cost and CO₂e factors for recycling location competitiveness reveal that increasing used garment prices makes locations with high import duties lose competitiveness, and that varying water freight CO₂e changes comparative location competitiveness.

The role of management control has not received sufficient attention in the literature on value creation so far. Therefore, this paper aims to investigate the role of control in value creation in industrial networks. More specifically, the aim is to examine the management and control of interfaces between key resources within and between firms, in the networks surrounding firms, when they attempt to create value. All the firms that take part in a value-creation process have both formal and informal control systems: these firms have budgets, specific routines, reward systems, and sanctioned “ways to behave.” The paper relates the Industrial Marketing and Purchasing (IMP) group's research on interaction, relationships, and networks with control literature, and presents a framework for controlling resource interfaces in a network setting. Two in-depth cases illustrate the role of control in value creation. The first case covers the development of a low-weight newspaper grade that Holmen and its paper mill Hallsta initiated. The second case examines the attempt to develop and commercialize a new, energy efficient pulping technology.

Purpose – The purpose of the chapter is to sketch the historical and evolutionary development of the Wichita Aircraft Manufacturing Cluster from inception to present and provide a descriptive narrative of aircraft industry knowledge spillovers currently driving effort to establish a Medical Device Manufacturing Cluster. The chapter illustrates how carbon-fiber composite materials knowledge and technology developed for use in the aviation industry is facilitating the creation and growth of medical device manufacturing.

Methodology/approach – We use an historical case study approach to trace the development of the aircraft cluster in the Wichita, KS metropolitan area. A number of technologies are identified that had initially been adopted by one firm but eventually diffused through other firms in the local cluster and ultimately throughout the industry.

Findings – In addition to providing examples of within industry knowledge spillovers, we provide an example of technology-based knowledge that is diffusing through the aircraft manufacturing industry and is now being used as the basis for establishing an unrelated industry manufacturing cluster. The use of carbon-fiber composites in aircraft manufacturing has diffused from one manufacturer to many in the industry. Subsequently, the knowledge base surrounding carbon-fiber composite materials is being used in a local R&D effort to create a second manufacturing cluster producing medical devices ranging from surgical instruments to joint-replacement implants.

Originality/value of paper – The chapter illustrates a unique example of a manufacturing cluster, intra-industry knowledge spillovers, and inter-industry knowledge spillovers to create a new manufacturing cluster.
