Challenges, Strategies, and Recommendations for the Huge Surge in Plastic and Medical Waste during the Global COVID-19 Pandemic with Circular Economy Approach
AI summary Read the abstract
Researchers reviewed how the COVID-19 pandemic accelerated plastic and medical waste generation and proposed circular economy strategies — including biodegradable plastics and improved disinfection — to prevent the surge in single-use plastics from creating a lasting microplastic pollution crisis.
After December 2019, the globe was affected by a new coronavirus (SARS-CoV-2) that causes severe respiratory illnesses, which is responsible for increasing environmental problem consequences related to the extra consumption of medical waste and single-use plastics (such as personal protective equipment (PPE) and packaging plastics). Although the consumption of these plastics protects our life during this crisis, it is pivotal to move toward plastic recycling processes and environmentally friendly and sustainable alternatives, like bio-based degradable plastics with a circular economy perspective. This review article collected scattered information and provided a future perspective on how worldwide COVID-19 disruption can perform as a catalyst to improve plastic and medical waste management. Additionally, this paper illustrates the most effective disinfection technologies for COVID-19 wastes, such as high/low heat technologies and chemical disinfection, and PPE reusing processes, including dry heat, vaporized hydrogen peroxide, ozone, and UV light during the outbreak. In this vein, medical waste treatment facilities must be more automatic, with a minimum of personnel involved. Moreover, some recent valid guidelines from different international organizations and countries, future outlook, and practical recommendations that could be effective during this epidemic or even in the post-pandemic world for plastic and medical waste management were provided. Ultimately, governments should improve their waste management because of the potential of pathogen transmission or increased plastic and medical waste generation and try to enhance the environmental knowledge of society. People also should revise their viewpoints on plastic consumption by elevating sustainable behaviors, abandoning old habits, and adjusting to novel ones.
