Chris DeArmitt, author of The Plastics Paradox, separates fact from fiction around the environmental impact of plastics. Topics include misconceptions about plastic degradation and endocrine-disrupting chemicals, the energy efficiency of plastics, the role of recycling, and the future of plastics in terms of biodegradability and compostability.

Quick takeaways
Plastic bags have the least environmental impact compared to other materials like paper, cotton, metal, or glass.
Plastics have significantly reduced waste going into landfills and are easily recyclable.
Concerns about the health effects of plastic leaching chemicals are often overblown, as plastics used for food contact must meet FDA regulations and undergo rigorous testing.
Plastics are a greener option in terms of energy consumption and environmental impact compared to materials like aluminum.
Deep dives
Plastic's Greenness and Misconceptions
Plastic is often demonized, but studies consistently show that plastic is the least harmful option for the environment compared to paper, cotton, metal, or glass. Life cycle analyses, which consider the environmental impact of every stage of production, consistently demonstrate that plastic bags, for example, have the least impact in terms of water use, greenhouse gas emissions, fossil fuel consumption, waste generation, and human and ecological impact. Plastics account for just 0.5% of materials used, while concrete and ceramics make up over 80%. Plastics have significantly reduced waste going into landfills over the years. The perception that plastics do not degrade is false, as plastics do degrade and biodegrade. In fact, billions of dollars are spent on plastic stabilizers to prevent excessive degradation. Plastics are easily recyclable, with about 90% of plastics being recyclable. While recycling rates vary, there are successful companies that recycle large amounts of plastic profitably. The environmental impact of plastics is often exaggerated, and other materials can have their own environmental drawbacks. The overall impact of using plastics, when considering their greenness and recyclability, is significantly lower than many other materials.
The Misconceptions Around Plastics and Health Concerns
Concerns about the health effects of plastic leaching chemicals are often overblown. Plastics used for food contact must meet FDA regulations and undergo rigorous testing. Substances like BPA, which was of previous concern, comprise less than 1% of plastics and are present in incredibly low amounts. The migration of chemicals from plastics is minimal, and the vast majority of plastics pose no health risks. Comparatively, other materials like certain metals can have more significant toxicity concerns. The focus on plastics should not detract from addressing more pressing environmental and health issues.
Recycling and Energy Use
Plastic recycling is a viable and profitable industry, with many companies successfully recycling plastics. The recycling process for plastics involves melting and remolding the materials, which requires less energy compared to other materials like metals. The energy required to create and recycle plastics is significantly lower than that of other materials like aluminum. Plastics are more energy-efficient and provide a greener option when considering the overall energy consumption and environmental impact.
The Importance of Perspective and Misinformation
A balanced perspective is crucial when evaluating the environmental impact of plastics. Plastics account for a small percentage of overall materials and waste, yet are often the primary focus of concern. It is important to acknowledge other materials that have a larger impact, such as concrete, ceramics, and metals. Misinformation and misconceptions surrounding plastics can lead to misguided actions and lack of focus on more significant environmental issues. It is critical to base opinions on scientific evidence and avoid generalizations or demonization of plastics.
Plastic is not inherently bad for the environment
Plastic's negative reputation as a pollutant is based on misinformation. While it is true that some things said about plastics have been incorrect, such as claims about recycling and bioplastics, the overall premise that plastic is inherently harmful is incorrect. Studies have shown that driving less, taking fewer flights, and eating less meat have a much bigger impact on the environment than using plastic bags. Plastic has been demonized and turned into a cult-like issue, fueled by NGOs and sensationalist media. The media often amplifies the dangers of microplastics, exaggerating the scientific evidence and causing unnecessary fear and panic.
The exaggerated threat of microplastics
Media articles have disproportionately portrayed microplastics as a definite danger, with 93% of articles suggesting their harmful effects compared to only 20% of scientific articles. However, the reality is that microplastics pose a much smaller risk than often claimed. Scary statistics like consuming a credit card's worth of plastic each week or there being more plastic than fish in the ocean are simply untrue. The misinformation is fueled by NGOs and media outlets seeking to generate donations and clicks. Even when confronted with evidence debunking their claims, many journalists and environmental groups ignore the truth.
Plastics industry and environmental impact
Plastic is a widely vilified material, yet it is often the most environmentally friendly option in various applications. Life cycle studies consistently show that plastics, including bags, containers, and straws, are greener alternatives compared to other materials such as metal or paper. Plastics contribute significantly less to CO2 emissions than renewable materials like wood or cotton. Additionally, the environmental impact of plastics, such as ingesting microplastics, is often blown out of proportion. Other pollutants, such as soot, dust, and toxic materials like cotton and metal residue, pose much greater health and environmental risks. The focus on plastics distracts from more substantial ecological challenges.
