Chemical Recycling of Plastic: A Promising Solution or a Misleading Mirage?

In the ever-evolving narrative of environmental conservation, the concept of chemical recycling of plastic has emerged as a contentious topic, stirring debates among experts, environmentalists, and industry leaders. This process, also known as advanced recycling, is an innovative approach that aims to transform plastic waste into fuel or new plastic products.

However, its effectiveness and environmental impact are under intense scrutiny.

The Complex Reality of Plastic Recycling

Imagine a world where every grocery trip or online order adds to the ever-growing pile of plastic waste. This scenario is not far from reality. In the United States, the recycling system is grappling with challenges, as only specific types of plastics (types 1 and 2) are efficiently recyclable.

The stark reality is that a mere 5-6% of plastic gets recycled. Enter chemical recycling – a process touted by major petrochemical companies as a game-changer in managing plastic waste and achieving a circular economy.

However, a report by the International Pollutants Elimination Network (IPEN) and Beyond Plastics paints a different picture. It argues that chemical recycling is not only unproven but also exacerbates pollution. This revelation comes amidst ongoing negotiations for a global plastics treaty, which aims to address plastic pollution comprehensively.

The treaty, however, faces resistance from fossil fuel and petrochemical companies.

Chemical Recycling: A Closer Look

Chemical recycling encompasses technologies like pyrolysis and gasification, which break down plastic waste into fuels or new plastics. Despite these promising descriptions, the IPEN and Beyond Plastics report highlights a grim reality.

Most chemical recycling facilities produce minimal usable plastic feedstock and generate hazardous waste harmful to the environment and human health.

Lee Bell, the report’s lead author and IPEN’s policy advisor, expressed concerns in an interview with Mongabay: “We’re being misled into a false solution.” This sentiment is echoed by environmentalists who argue that chemical recycling’s environmental and climate impacts could be 100 times more damaging than producing virgin plastic.

In contrast, Ross Eisenberg of America’s Plastic Makers defends chemical recycling, citing a study by the Argonne National Laboratory. The study suggests that chemical recycling can reduce greenhouse gas emissions and fossil energy use.

However, Bell counters this by pointing out the study’s reliance on industry data and its failure to address the toxicity of emissions from the pyrolysis process.

1. A Global Perspective on Plastic Pollution

The urgency for effective plastic waste solutions is undeniable. Annually, about 430 million metric tons of plastic are produced – a figure that could triple by 2060. This escalation in plastic production is pushing Earth’s ecological boundaries, contributing to the breach of critical thresholds that maintain our planet’s safe operating space.

Despite these alarming statistics, the debate over chemical recycling’s viability continues. While it offers a potential solution for non-recyclable plastics, its risks and inefficiencies raise significant concerns. The process generates toxic waste and emissions, posing health hazards and contributing to climate change.

2. The State of Chemical Recycling Facilities

The American Chemistry Council (ACC) advocates for expanding chemical recycling facilities, yet the current state of these plants in the U.S. is underwhelming.

Of the few operational facilities, many are not performing at full capacity or delivering on their promises. For example, a Brightmark Energy facility in Indiana, despite receiving federal subsidies, has processed only a fraction of its projected plastic waste recycling capacity.

The situation in Europe presents a different challenge. While U.S. plants can label themselves as recycling facilities, European plants converting waste plastic to fuel do not enjoy the same classification. Lauriane Veillard, a policy officer at Zero Waste Europe, highlights the need to focus on reducing plastic consumption and promoting reuse, rather than solely relying on recycling improvements.

Future Prospects of Chemical Recycling

The future of chemical recycling hinges on transparency and data availability. Bell emphasizes the lack of industry data on toxic emissions and hazardous waste, which hampers environmental regulation and informed policymaking. The Basel Convention on hazardous waste recently rejected chemical recycling as an environmentally sound management technique, citing its unproven nature.

As negotiations for the global plastics treaty continue, the role of chemical recycling remains uncertain. Countries heavily invested in the petrochemical industry, such as Russia, Saudi Arabia, and Iran, have shown resistance to the treaty’s progress.

The involvement of over 140 lobbyists from the fossil fuel and petrochemical industries in these negotiations further complicates the picture.

Final Thought

While chemical recycling presents an innovative approach to tackling the plastic waste crisis, its effectiveness and environmental impact remain contentious.

The need for more comprehensive data, transparent practices, and a holistic approach to plastic waste management is paramount. As the world grapples with the escalating plastic pollution problem, the debate over chemical recycling’s role in a sustainable future continues to unfold.
