Plastic pollution is ubiquitous in terrestrial and aquatic ecosystems. Plastic waste exposed to the environment creates problems and is of significant concern for all life forms. Plastic production and accumulation in the natural environment are occurring at an unprecedented rate due to indiscriminate use, inadequate recycling, and deposits in landfills. In 2019, the global production of plastic was at 370 million tons, with only 9% of it being recycled, 12% being incinerated, and the remaining left in the environment or landfills. The leakage of plastic wastes into terrestrial and aquatic ecosystems is occurring at an unprecedented rate. The management of plastic waste is a challenging problem for researchers, policymakers, citizens, and other stakeholders. Therefore, here, we summarize the current understanding and concerns of plastics pollution (microplastics or nanoplastics) on natural ecosystems. The overall goal of this review is to provide background assessment on the adverse effects of plastic pollution on natural ecosystems; interlink the management of plastic pollution with sustainable development goals; address the policy initiatives under transdisciplinary approaches through life cycle assessment, circular economy, and sustainability; identify the knowledge gaps; and provide current policy recommendations. Plastic waste management through community involvement and socio-economic inputs in different countries are presented and discussed. Plastic ban policies and public awareness are likely the major mitigation interventions. The need for life cycle assessment and circularity to assess the potential environmental impacts and resources used throughout a plastic product’s life span is emphasized. Innovations are needed to reduce, reuse, recycle, and recover plastics and find eco-friendly replacements for plastics. Empowering and educating communities and citizens to act collectively to minimize plastic pollution and use alternative options for plastics must be promoted and enforced. Plastic pollution is a global concern that must be addressed collectively with the utmost priority.

Organizations face increasing pressure from stakeholder groups to adopt sustainable practices and improve their environmental performance. Contemporary frameworks on corporate environmental responsibility observe that stakeholders positively influence organizational response in the form of adoption of sustainable operations practices. However, these frameworks provide little evidence on the distinction between the influences of different stakeholder groups on shaping organizations’ environmental responses. This paper proposes and empirically tests how different stakeholder groups, directly and indirectly, influence organizational adoption of sustainable operations practices. Based on a sample from an emerging economy, we show that the primary stakeholders, because of the reciprocal and direct transactional relationship with the firm, directly influence an organization's environmental policies. By contrast, secondary stakeholders try to influence organizations indirectly via primary stakeholders. The results indicate that there is a distinction between different stakeholder groups, and secondary stakeholders can exercise their influence over organizational environmental decisions via primary stakeholders.

Purpose Contemporary frameworks on institutional theory and corporate environmentalism observe that institutional fields positively influence a firm’s environmental response in the form of implementation of environmental practices. These frameworks, however, provide little evidence on why firms facing similar institutional field differ in their environmental response. This paper aims to incorporate the intra-organizational dynamics within the traditional institutional theory framework to address this heterogeneity, examining specifically the role of absorptive capacity for environmental knowledge in the organizational implementation of corporate environmental practices. Design/methodology/approach Integrating the institutional theory and resource-based view, this paper examines the mediating role of absorptive capacity in the relationship between institutional pressure for corporate environmentalism vis-a-vis the implementation of corporate environmental practices. Partial least square structural equation modeling was used for hypotheses testing based on data obtained from the Indian apparel and textile industry. Findings The results support the mediating role of absorptive capacity in the relationship between institutional pressure and implementation of corporate environmental practices. Further, this study highlights the importance of acquisition and utilization of environmental knowledge in driving environmentalism through developing absorptive capacity; the findings also suggest that the role of institutional pressure in the implementation of environmental practices should not be analyzed in isolation but rather in conjunction with the development of absorptive capacity that forms the internal basis of implementation. Practical implications Managers need to focus on the development of organizational capabilities for acquiring and exploiting environmental knowledge to complement their preparedness in responding to any institutional pressures for environmental sustainability. Firms also need to link their environmental orientation with various sources of environmental knowledge and capabilities residing outside the organizational boundaries. It is important to note here that the development of absorptive capacities for the exploration and exploitation of external knowledge is indeed both required and necessary to build sustainable organizational capabilities. Originality/value This paper is among the very few studies that address the issue of knowledge and development of related organizational capabilities for corporate environmentalism. Recognizing that environmental knowledge resides outside organizational boundaries with regulatory agencies and special interest groups, this paper highlights the importance of developing organizational capabilities for the acquisition and exploitation of environmental knowledge.

Deciphering user purchase preferences, their likes and dislikes is a very tricky task even for humans, making its automation a very complex job. This research work augments heuristic-driven user interest profiling with reviewer credibility analysis and fine-grained feature sentiment analysis to devise a robust recommendation methodology. The proposed credibility, interest and sentiment enhanced recommendation (CISER) model has five modules namely candidate feature extraction, reviewer credibility analysis, user interest mining, candidate feature sentiment assignment and recommendation module. Review corpus is given as an input to the CISER model. Candidate feature extraction module uses context and sentiment confidence to extract features of importance. To make our model robust to fake and unworthy reviews and reviewers, reviewer credibility analysis proffers an approach of associating expertise, trust and influence scores with reviewers to weigh their opinion according to their credibility. The user interest mining module uses aesthetics of review writing as heuristics for interest-pattern mining. The candidate feature sentiment assignment module scores candidate features present in review based on their fastText sentiment polarity. Finally, the recommendation module uses credibility weighted sentiment scoring of user preferred features for purchase recommendations. The proposed recommendation methodology harnesses not only numeric ratings, but also sentiment expressions associated with features, customer preference profile and reviewer credibility for quantitative analysis of various alternative products. The mean average precision (MAP@1) for CISER is 93% and MAP@3 is 49%, which is better than current state-of-the-art systems.
