Abstract: Developing nations, including India, face a number of daunting challenges in the twenty-first century, including population growth, political strife, rapid urbanization, food and water scarcity, environmental pollution, infectious diseases, and climate change. In this turbulent era, there is a need for resilience at every level-from the village family to the corporate boardroom to the halls of government. We argue that achieving resilience will require both enlightened government policies and successful initiatives by social and environmental innovators that demonstrate the capacity for adapting to these challenges. Such practical first steps can serve as models for creating a more resilient and sustainable economy in India. One way to stimulate rapid progress is development of circular economy solutions that create innovative pathways for utilization of discarded materials, thus seeking to eliminate waste. Previous research has shown that such initiatives reduce environmental pressures and improve community resilience, while stimulating the regional economy. An international conference on Waste Management Innovation, held in 2017 in Mumbai with funding from the US Consulate General, resulted in the award of seed grants to two Indian non-profits that sought to apply circular economy principles to regional communities-one urban and one rural. These initiatives provide case studies of circular economy implementation. The World Institute of Sustainable Energy has developed an action plan to capture at least 60 percent of the electronic waste generated in the city of Pune, one of the largest metropolitan areas in India. Their approach is based on circular economy principles, and has been embraced in stakeholder meetings with city officials as well as local residents and non-governmental organizations. Barefoot College has established and demonstrated a low-cost, end-to-end solid waste management model for rural villages that is designed by the local community. Their unique approach ensures sanitation, environmental protection, income and livelihood generation, and drives behavioral change in village residents by motivating them to maintain community hygiene. This paper presents the results of these two efforts, and suggests what lessons were learned. One overarching insight is that an integrated systems view is necessary to understand the interplay of economic, environmental, and social forces.

In this study, stems and leaves of the papaya plant were employed to prepare a high-quality porous adsorbent carbonization and chemical activation using phosphoric acid. This adsorbent demonstrates superior adsorption capabilities for the efficient removal of hazardous alizarin red s (ARS) and methylene blue (MB) dyes. Thus, it contributes to waste reduction and promotes sustainable practices in environmental remediation, aligning with global efforts to develop sustainable materials that address water pollution while supporting circular economy principles.

The use of 3D-printed electrodes is reported fabricated from in-house conductive filament composed of a mixture of recycled poly (lactic acid) (rPLA), graphite (Gpt), and carbon black (CB) for fast detection of the abused drug ketamine. Firstly, the performance of these electrodes was evaluated in comparison to 3D-printed electrodes produced employing a commercially available conductive filament. After a simple pretreatment step (mechanical polishing), the new 3D-printed electrodes presented better performance than the electrodes produced from commercial filament in relation to peak-to-peak separation of the redox probe [Fe(CN)]/ (130 mV and 759 mV, respectively), charge transfer resistance (R = 1.

Industrial wastewaters are significant global concerns due to their environmental impact. Yet, protein-rich wastewaters can be valorized by enzymatic hydrolysis to release bioactive peptides. However, achieving selective molecular differentiation and eventually enhancing peptide bioactivities require costly cascades of membranes.

Blue food processing applies to the production and processing of fish, algae, and other aquatic organisms for human consumption. As the global population grows and consumer demand for protein-rich foods increases, there is increased interest in exploring a wide range of innovative approaches for processing blue foods in ways that improve the efficiency, sustainability, and nutritional quality of these products and reduce the environmental impact of their production. Existing approaches to process blue foods including fishing and aquaculture for production and manual processing at landing are not sufficiently scalable, efficient, or environmentally sustainable for today's global needs.

This study evaluated the effects of incorporating biological silage from tambaqui (Colossoma macropomum) by-products (BST) on the performance, hematological and plasma biochemical parameters, and egg quality (physical, proximate composition and sensory characteristics) of older commercial hens. The BST was prepared by ensiling tambaqui by-products with lactic acid bacteria, cassava trimmings, and preservatives, producing a nutrient-rich, high-protein feed ingredient. One hundred and twenty Hisex Brown hens (83 weeks old) were divided into five treatment groups, each receiving diets with 0, 1, 2, 3, or 4% BST.
