Predictions see the 2016 production level of 335 Mt climb to a staggering 1 800 Mt by 2050 (Figure 1., Ryan 2015) as the petrochemical industry shifts its output from fuels to chemicals and plastics in a carbon-constrained market.There has been widespread promotion of recycling, both mechanical and chemical, as a solution to the plastic waste problem but at current polymer production levels recycling is making very little impact, even in wealthy countries. When the bigger picture of massive plastic production growth and the lack of recycling infrastructure in low-income countries is considered, it becomes clear that plastic recycling is not the solution. Addressing the plastic contamination of the planet requires a range of approaches, but three elements are critical and must be prioritized:1. We must dramatically reduce the amount of plastic being produced – immediately.2. We must address existing stockpiles of plastic waste (controlled, uncontrolled, and landfills) in an environmentally sound manner.3. We must develop an environmentally sound, sustainable management system for any plastic produced in the future. This must include implementation of design, production, and end-of-life management systems that maximize polymer reuse and recycling in low-income countries as well as wealthy countries.Put simply, we must ramp down plastic production to essential uses, deal with legacy stockpiles, and redesign plastic produced in the future to allow for environmentally sound management (ESM) within the framework of a global circular economy that does not dump plastic waste on low-incomecountries.This main focus of this report is how to address existing stockpiles of plastic waste and potential methods for managing current and future end of life plastics. Reducing production of plastics is a political and regulatory issue outside the scope of this report.
