The past, present, and future of plastic pollution

Area of Science:

• Environmental Science
• Materials Science
• Economics

Background:

• Plastic production has exponentially increased, with 9.2 billion tonnes produced between 1950 and 2017.
• Approximately 8-11 million tonnes of plastic waste enter the oceans each year.
• The packaging industry is a major contributor, accounting for 47% of plastic usage.

Purpose of the Study:

• To evaluate the effectiveness of current solutions like recycling and the circular economy in addressing plastic pollution.
• To highlight the need for new technologies and upstream waste reduction strategies.
• To advocate for a legally binding global governance framework for plastic pollution control.

Main Methods:

• Analysis of plastic production and waste generation data.
• Review of existing waste management strategies, including recycling, Extended Producer Responsibility (EPR), and Deposit Return Schemes (DRS).
• Assessment of the impact and limitations of the circular economy model on plastic circulation.

Main Results:

• Despite initiatives like the circular economy, plastic circulation continues to grow.
• Current recycling and waste management approaches have not sufficiently curbed the plastic pollution crisis.
• There is a growing consensus among governments favoring international cooperation.

Conclusions:

• No single solution can solve the plastic pollution problem.
• There is an urgent need for technological innovation in waste management and product design.
• A legally binding global governance arrangement is essential to effectively limit and control plastic pollution at its source.
