Why is oxo-degradable bad?

2023-10-13

Oxo-degradable plastics are often marketed as an environmentally friendly alternative to traditional plastics. They are designed to degrade into smaller pieces through exposure to sunlight, heat, and oxygen. However, there is growing evidence that oxo-degradable plastics are not as eco-friendly as they claim to be and can have detrimental effects on the environment. In this article, we will explore why oxo-degradable plastics are bad and why their use should be reconsidered.

1. Incomplete degradation: One of the major drawbacks of oxo-degradable plastics is that they do not fully degrade. Instead, they break down into smaller fragments known as microplastics. These microplastics are a significant environmental concern, as they can persist in the environment for a long time, accumulate in ecosystems, and have adverse effects on wildlife.

2. Contamination of recycling streams: Oxo-degradable plastics can contaminate recycling streams, making it difficult to separate and recycle different types of plastics effectively. These plastics can be mistakenly sorted with recyclable plastics, leading to the production of recycled materials with lower quality and reduced value. The contamination also increases the cost and complexity of recycling processes, which hinders the development of a circular economy for plastics.

3. Harm to wildlife: Microplastics derived from oxo-degradable plastics can enter water bodies and affect marine life. Fish and other marine organisms may ingest these tiny particles, leading to physical harm and long-term health complications. The presence of microplastics in the food chain can also eventually reach humans, potentially posing risks to human health.

4. Soil pollution: Oxo-degradable plastics that degrade in landfills can release harmful chemicals and additives into the soil. These substances can contaminate groundwater, adversely affecting plant growth and disrupting ecosystem balance. Additionally, the presence of plastic fragments in the soil can hinder soil functionality by impeding water retention and nutrient absorption.

5. False sense of environmental responsibility: Oxo-degradable plastics are often marketed as a sustainable solution, leading consumers to believe that using these plastics is minimizing their environmental impact. However, due to the incomplete degradation and associated environmental implications, these claims can be misleading. Instead of embracing more sustainable alternatives, individuals may unknowingly contribute to environmental degradation by using oxo-degradable plastics.

6. Lack of standardization: The lack of standardized testing methods for oxo-degradable plastics leads to inconsistent claims and confusion. Different manufacturers may have varying formulations and degradation rates, making it challenging to understand their environmental impact accurately. This lack of consistency also complicates waste management strategies, making it harder to develop effective policies and regulations regarding oxo-degradable plastics.

7. Alternatives available: Sustainable alternatives to oxo-degradable plastics, such as compostable or biodegradable plastics, exist and are being widely adopted. These alternatives are designed to fully degrade under specific environmental conditions, leaving minimal or no harmful residues behind. Choosing these alternatives over oxo-degradable plastics can help reduce environmental damage and promote a more sustainable future.

In conclusion, despite their apparent benefits, oxo-degradable plastics are not as environmentally friendly as they are marketed to be. Their incomplete degradation, contamination of recycling streams, harm to wildlife, soil pollution, false sense of environmental responsibility, lack of standardization, and the availability of better alternatives all contribute to the argument against their use. It is crucial for individuals, businesses, and policymakers to be aware of these issues and work towards adopting truly sustainable alternatives to minimize the environmental impact of plastic waste.
