Moving from Linear to Circular Economy in Saudi Arabia: Life-Cycle Assessment on Plastic Waste Management

Researchers conducted a life-cycle assessment comparing five different plastic waste management approaches in Saudi Arabia, from landfilling to recycling and incineration. They found that mechanical recycling combined with energy recovery had the lowest overall environmental impact, while landfilling, the country's current dominant practice, performed the worst. The study provides a data-driven roadmap for Saudi Arabia's transition from a linear to circular economy for plastic waste management.

COVID19-Plastic Waste Management Towards Sustainable Circular Economy: Focus on Qatar & Kingdom of Saudi Arabia

This study examines plastic waste management in Qatar and Saudi Arabia following the COVID-19 pandemic, finding that 82% of coastal plastic waste enters the Persian Gulf with Saudi Arabia contributing the highest marine microplastic load (up to 235,000 tons). Both countries recycle less than 15% of plastic waste, and polypropylene from PPE is the dominant post-pandemic polymer. The authors call for circular economy approaches including improved recycling and waste management infrastructure.
