Sustainable Manufacturing and operations has become a crucial issue in present scenario for the manufacturing firms. Today manufacturing firms are keen interested to become sustainable in all three aspect economical social and environmental. There are number of manufacturing practices viz. Eco-design, process design, green supply chain, lean practices, product recovery and cleaner production by which firms should achieve sustainability. This paper present an AHP model of manufacturing sustainability through different manufacturing practices. In the initial stage of this study a survey methodology used from academia and industry after that an AHP model developed. From this study it is identified that firm EP-3 more conscious towards sustainability with respect to other firm. It is suggested that every electrical panel industry should adopt sustainable manufacturing practices to achieving competiveness in the market.

Purpose In the current global manufacturing scenario, all most all major players are now in a position to commit themselves to sustainability in all their operational initiatives and each of them follow their own methodology to attain their goal of sustainability. The purpose of this paper is to assess the sustainable manufacturing practice (SMP) in Indian manufacturing sector. This paper is also focused on the how lean practice leads to the sustainable manufacturing (SM). Design/methodology/approach A survey methodology is used for this research. The SMPs are identified for the literature review and survey questionnaire was framed. In all, 345 usable responses from four sectors namely automobile, electrical and electronics, machinery and process were collected through Google survey. Findings This research is focused on the SMPs. From this research it is found that sustainable product and process design (SPPD), lean practices (LP), agile practice and customization, sustainable supply operation and distribution and product recovery and return practices lead to the SM. Research limitations/implications This study has some limitations, which future researchers could consider. The large industries of Indian manufacturing across four sectors have been considered, the study can be further taken up to the micro, small and medium enterprises of the Indian manufacturing scenario. The questionnaire can be further developed as that it can be used for a global survey across various sectors and then comparison can be made between the Indian companies and their global counterpart. In future longitudinal studies can be conducted by considering the other SMPs like mass customization, smart manufacturing practices, etc. Practical implications The present research helps the stakeholders to develop strong regulatory norms/policies to promote the SMPs in Indian manufacturing industries. This research may help production/manufacturing managers/practitioners to understand various issues related to SM and how they can be used gainfully to improve their practices and performances towards sustainable development. Social implications This study enriches the corporate social responsibility in the organization. Corporate social responsibilities activities to be undertaken by the company shall include poverty and malnutrition, promoting health care including preventive health care and sanitation including contribution to the Swachh Bharat Kosh set-up by the Government of India for the promotion of sanitation and making available safe drinking water. This reinforces the company broader aim through its business activities to contribute to the wellbeing and sustainable development. Originality/value This study offers evidence of the implementation of SMPs namely SPPD, LP, agile practices and customization, sustainable supply operation and distribution and product recovery and return practices in Indian manufacturing organization. The authors propose a conceptual framework for SMPs and empirically tested.

The present work focuses on the evaluation of polymer, metal and ceramic based biomaterials with particular emphasis on success rate of these materials till date along with the merits and demerits of these material system. Currently, the search for the materials with improved performance is on rise for biomedical (mainly total hip replacement, THR) applications owing to increase in the number of orthopedic patients worldwide. The clinicians utilized polymer and metal-based implants in ancient times to heal and treat the bone imperfections as well as fractures. The next generation materials required an update on properties, cell material interactions, repair and regeneration, that can only be acquired from recent knowledge related to materials. The commonly employed polymers (natural based polymers, proteins or polysaccharides; and synthetic polymers, poly (lactic acid), poly (glycolic acid), poly (ε-caprolactone), poly(3-hydroxybutyrate) (PHB)) and metals (SS, Mg-alloy, Ti-alloys, Co-alloy, silver, and nickel-titanium alloys) failed to fulfill the long-term durability and lacked in generating adequate bonding with the bones. It is intended that the facts and details abridged in this review article ought to be a beneficial tool in the development of progressively eminent implant materials like ceramic based materials against premature failure, cyclic stress generation, wear, corrosion fatigue, implant loosening and ultimate fracture.
