Big data: Issues, challenges, tools and Good practices

Abstract: Big data is defined as large amount of data which requires new technologies and architectures so that it becomes possible to extract value from it by capturing and analysis process. Due to such large size of data it becomes very difficult to perform effective analysis using the existing traditional techniques. Big data due to its various properties like volume, velocity, variety, variability, value and complexity put forward many challenges. Since Big data is a recent upcoming technology in the market which can bring huge benefits to the business organizations, it becomes necessary that various challenges and issues associated in bringing and adapting to this technology are brought into light. This paper introduces the Big data technology along with its importance in the modern world and existing projects which are effective and important in changing the concept of science into big science and society too. The various challenges and issues in adapting and accepting Big data technology, its tools (Hadoop) are also discussed in detail along with the problems Hadoop is facing. The paper concludes with the Good Big data practices to be followed.

Bioadsorbents for remediation of heavy metals: Current status and their future prospects

Abstract: The biosorption process has been established as characteristics of dead biomasses of both cellulosic and microbial origin to bind metal ion pollutants from aqueous suspension. The high effectiveness of this process even at low metal concentration, similarity to ion exchange treatment process, but cheaper and greener alternative to conventional techniques have resulted in a mature biosorption technology. Yet its adoption to large scale industrial wastewaters treatment has still been a distant reality. The purpose of this review is to make in-depth analyses of the various aspects of the biosorption technology, staring from the various biosorbents used till date and the various factors affecting the process. The design of better biosorbents for improving their physico-chemical features as well as enhancing their biosorption characteristics has been discussed. Better economic value of the biosorption technology is related to the repeated reuse of the biosorbent with minimum loss of efficiency. In this context desorption of the metal pollutants as well as regeneration of the biosorbent has been discussed in detail. Various inhibitions including the multi mechanistic role of the biosorption technology has been identified which have played a contributory role to its non-commercialization.

Barriers to effective circular supply chain management in a developing country context

Abstract: Circular supply chain emphasizes surge in application of reuse, recycling and remanufacturing and thereby promotes the transformation of manufacturing characteristics from linear (‘take-produce-utilize-dump’) to circular model of flow of products, by-products and waste. Supply chains of manufacturing industries have become global in last few decades. Products manufactured in developing nations like India and China are being sent to developed nations for consumption in higher volumes. Developed nations have the regulatory policies, technological knowhow and modern infrastructure to adopt circular supply chain model. Their counterpart is trailing in these aspects. In literature, limited research work has been performed on identifying challenges of implementing circular supply chain management in developing nations and their contextual association. In this article, based on thorough literature review and feedback received from experts, sixteen important barriers were identified to circular supply chain management adoption in Indian context. The listed barriers were then analysed using an integrated Interpretive Structural Modelling - MICMAC approach. This study attempts to identify the contextual interactions among identified barriers and to examine their hierarchical levels in effective adoption and implementation of circular supply chain management. The findings of this research will contribute in transforming supply chains in terms of bringing economic prosperity, addressing global warming issues and generating numerous employment opportunities. Finally, some crucial policy measures and recommendations are proposed to assist managers and government bodies to adopt and manage the concepts of circular supply chains effectively in Indian context.
