The Facts About Oxo-Degradable Plastic

Plastic has become an integral part of our daily lives, from packaging to household items. However, the environmental impact of plastic waste has become a growing concern. In an effort to address this issue, companies have introduced "green" plastic alternatives, including oxo-degradable plastic.

But is this type of plastic truly environmentally friendly? In this article, we will talk about oxo-degradable plastic and topics like:

• What is oxo plastic?
• Why is oxo plastic bad?
• What are the environmental impacts of oxo plastic?
• What are some alternatives to oxo plastic?

What is Oxo-Degradable Plastic?

Oxo-degradable plastic is a type of plastic that is made to break down into smaller pieces when exposed to elements like oxygen and sunlight. This process, known as oxidation, accelerates the breakdown of the plastic.

How does oxo plastic break down?

The rapid breakdown process of oxo plastic is caused by its additives. When oxo plastic is made, metal salts are added. These salts, which include transition metals like nickel and iron, are the first to decompose once the plastic is exposed to sunlight and oxygen. This process takes as little as 12 months.

How is it Different from Traditional Plastic?

Traditional plastic, which is made from petroleum-based materials, does not break down easily. This means that plastic waste can take hundreds ofyears to decompose, leading to a buildup of plastic in landfills and the environment. Oxo-degradable plastic is made to break down faster, potentially decreasing plastic waste in the environment. However, this is not the case.

Why is Oxo-Degradable Plastic bad?

Oxo-degradable plastic companies often market it as "biodegradable" or "compostable", which is one of its main issues. However, these terms are greenwashing as the plastic does not fully break down into natural elements. Instead, it breaks down into smaller pieces of plastic, called microplastics.

Currently, there are no set rules for making oxo-degradable plastic. This means that each company can use different methods and materials to create their own version of this plastic. This lack of standardization makes it difficult to determine the true environmental impact of oxo-degradable plastic.

Are oxo-degradable plastics banned?

In 2018, the European Union called for a restriction of oxo plastic due to the murky claims of their benefit for the environment. This led to complete bans in France, Spain, and among the EU Single Use Plastic Directive.

The United States Federal Trade Commission sent out over 15 cease and desist letters to fight against companies that were falsely claiming oxo plastic to be biodegradable. More recently, large companies like PepsiCo, Nestle, Unilever, and 150 other companies globally have initiated total bans on the use of oxo plastic.

What are the Environmental Impacts of Oxo-Degradable Plastic?

Oxo-degradable plastic has additives that speed up its breakdown when exposed to sunlight or heat. Although it may seem good at first, there are worries about how it will affect the environment.

Landfill Buildup

Despite its ability to break down more quickly than traditional plastic, oxo-degradable plastic still ends up in landfills because unfortunately it is not recyclable. Oxo-degradable plastic needs sunlight or heat to break down and degrade properly.

Plastic will not break down as planned in landfills but may break down in oceans due to different conditions. This can lead to an increase in plastic waste in these areas. It worsens the problem of plastic pollution and creates additional challenges for waste management.

Pollution

One of the main concerns with oxo-degradable plastic is that it does not fully biodegrade. Instead, it breaks down into smaller fragments known as microplastics, which remain in the environment for a long time. Microplastics can be ingested by marine animals and wildlife which disrupts their digestion and introduces toxic chemicals to the food chain.

The creation of microplastics contradicts the idea of oxo plastic being degradable as it essentially trades one problem for another. With microplastics being left behind in the breakdown process, this makes oxo plastic only partially degradable.

Greenhouse Gas Emissions

The production of oxo-degradable plastic still requires the use of fossil fuels, contributing to greenhouse gas emissions. Additionally, the breakdown of this plastic can also release methane, a potent greenhouse gas, into the environment.

What are the Alternatives to Oxo-Plastic?

Currently on the market are plastic bags, certain types of bottles, and other plastic products that are made from oxo. The best way to combat oxo plastic is to opt for alternatives like compostable products made from truly biodegradable materials or invest in reusable alternatives.

PLA

PLA, or Polylactic Acid,  is a type of bio-based plastic that can break down naturally. It is made from rapidly growing renewable resources like corn and sugarcane. PLA is better for the environment than traditional plastics when used in packaging materials like food packaging. It breaks down in a commercial composting environment and is generally certified compostable.

Compostable Materials

Compostable materials emerge as a promising alternative, offering a greener option for disposable products. These materials break down naturally, contributing nutrients to the soil without the drawbacks of traditional plastics. Some examples of compostable materials are bamboo, PLA, sugarcane fiber, and PHA.

Reusable Alternatives

The most environmentally friendly option is to reduce the use of common plastic altogether. Consider using reusable alternatives, such as glass or stainless steel containers, cloth shopping bags, and recyclable plastics.

Conclusion

The environmental concerns of oxo plastic are very worrisome. This seemingly “degradable” option is not quite fully degradable after all. Opting for eco-friendly alternatives like compostables is a great way to lessen the single use plastic impact. By working together, we can create a more sustainable future for our planet.
