While offering innovative solutions to existing waste management challenges, the study also suggests some key recommendations to the policymakers to help handle probable future pandemics if any holistically.•New challenges in MSW management in Tehran after the COVID-19 pandemic was studied.•Over 5.5 millions of PPEs are being daily discarded in Tehran during COVID-19.•Hospital wastes are being disposed of without undergoing any treatment in Tehran.•Landfilling of MSW has increased by 34.7% after the outbreak of COVID-19.•Secondary contagion from improper management of MSW is probable in Tehran.•Effective governance and efficient coordination across multi-levels and multi-sectors are pivotal factors to ensure food supply during COVID-19.•Digital tools and innovative models provided valuable solutions to cope with the crisis in China, which can be further developed and contribute to the "New Normal".•The pandemic implies the necessity to strengthen urban-rural linkages and foster local food production for more resilient local food systems.In this study, a natural surfactant, saponin was isolated from soapnut (Sapindus Mukorossi). The extracted surfactant was characterized by Fourier-transform infrared spectroscopy (FTIR) analysis. The effectiveness of the isolated surfactant as EOR agent was evaluated from foam generation/stabilization properties, wettability alteration of the rock surfaces, as well as oil-water interfacial tension (IFT) reduction characteristics. The performance of the extracted saponin was compared with that of a commercial saponin and so
