Plastic waste management during and post Covid19 pandemic: Challenges and strategies towards circular economy
AI summary Read the abstract
This study examines how the COVID-19 pandemic worsened plastic waste management by driving up PPE use and making virgin plastics cheaper than recycled alternatives, with 40% of plastic waste ending up in landfills globally. Researchers propose circular economy strategies—including feedstock recycling and waste valorization into fuels and building materials—to address the mounting crisis.
Global petroleum consumption suffered drastically as lockdowns were put in place to contain the Coronavirus Disease 2019 (COVID-19). As a result, oil costs dropped, making virgin plastics more cost-effective than recycled plastics. The usage of plastic has increased as a result of lifestyle modifications, cost-based incentives, and other factors, further obscuring the issue. The utilization of personal protective equipment (PPE) during the pandemic had resulted in a significant surge in the quantity of plastic waste. The plastic packaging industry achieved a revenue milestone of US$ 909.2 billion in 2021, boosting a compound annual growth rate of 5.5 %. The escalating dependence on plastics imposed additional pressure on waste management systems, which were proven to be ineffective and insufficient in addressing the issue. This situation exacerbated the problem and contributed to environmental pollution. Globally, 40 % of plastic waste ended up in landfills, 25 % was incinerated, 16 % was recycled, and the remaining 19 % infiltrated within the environment. By investing in circular technologies like feedstock recycling and enhancing infrastructural and environmental conditions, it expected to become viable to manage plastic waste flows during such a period of crisis. Investing in valorization strategies that transform plastic waste into value-added goods, such as fuels and building materials, receives a compelling macroeconomic signal when both plastic waste and plastic demand are on the rise. A robust circular economy can be accomplished by finalising the life cycle of plastic waste. The concept of Plastic Waste Footprint (PWF) aims to assess the environmental impact of plastic products throughout their intended usage period. In the midst of the emerging challenges in waste management during and post pandemic period, this research study has been conducted to explore the challenges and strategies associated with plastic waste in the environment.

Plastic wastes in the time of COVID-19: Their environmental hazards and implications for sustainable energy resilience and circular bio-economies
AI summary Read the abstract
This study examines how the surge in plastic waste during the COVID-19 pandemic, including personal protective equipment and packaging materials, has worsened environmental pollution. Researchers found that weathered plastic particles from PPE can adsorb chemical and microbial contaminants, posing risks to ecosystems and human health. The study argues that the pandemic could serve as an opportunity to improve life cycle assessment approaches and develop more sustainable plastic waste management strategies.
