INDIA- As for reported in 360 COVID-19 cases (till March 22, 2020), seven people were died, and 23 people were treated successfully.1 This virus can easily affect who having respiratory problem and especially who all have been aged older than sixty. Most of the affected peoples had reached India from different part of the world, as like of carrier. Owing to this, India made several precautionary measures to mitigate/neglect the disease in beginning stage, however, the denser population of country will not be simple to control the same for long time (community spread), if government will not incorporate the visionary strategies. Since attacked several nations have been worried mostly for their people life (health), despite that developing country like India with huge population should consider about the livelihood (for Below Poverty Line (BPL) people), equally with the life. This article will give insights to make effective strategy to culminate the world threat COVID-19 in India.

The aim to achieve sustainable development goals (SDG) and cut CO₂-emission is forcing researchers to develop bio-based materials over conventional polymers. Since most of the established bio-based polymeric materials demonstrate prominent sustainability, however, performance, cost, and durability limit their utilization in real-time applications. Additionally, a sustainable circular bioeconomy (CE) ensures SDGs deliver material production, where it ceases the linear approach from production to waste. Simultaneously, sustainable circular bio-economy promoted materials should exhibit the prominent properties to involve and substitute conventional materials. These interceptions can be resolved through state-of-the-art bio-vitrimeric materials that display durability/mechanical properties such as thermosets and processability/malleability such as thermoplastics. This article emphasizes the current need for vitrimers based on bio-derived chemicals; as well as to summarize the developed bio-based vitrimers (including reprocessing, recycling and self-healing properties) and their requirements for a sustainable circular economy in future prospects.

Vitrimeric materials have emerged as fascinating and sustainable materials owing to their malleability, reprocessability, and recyclability. Sustainable vitrimeric materials can be prepared by reinforcing polymeric matrix with bioderived fillers. In the current work, a sustainable vitrimer is prepared by incorporating biomass-derived activated carbon (AC) filler into the epoxy matrix to achieve enhanced thermal and mechanical properties. Thus, prepared biocomposite vitrimers demonstrate a lower-temperature self-healing (70°C for 5 min) via disulfide exchanges, compared to the pristine epoxy vitrimers (80°C for 5 min). Significantly, the self-healing performances have been studied extensively with the flexural studies; and changes in material healing efficiency have been demonstrated based on the observed changes in modulus.
