Are Silicone Products Really Better for the Environment Than Plastic?

Are Silicone Products Really Better for the Environment Than Plastic?

A few years ago, I switched from plastic food storage bags to silicone ones, hoping to make a more environmentally friendly choice. Like many of us, I was tired of contributing to the plastic pollution problem, and silicone seemed like the perfect alternative—reusable, durable, and safe. However, as I delved deeper into the environmental impact of silicone, I discovered that the answer to whether silicone is better than plastic is not as straightforward as I had hoped.

The issue of plastic pollution is one we are all too familiar with. From oceans teeming with plastic waste to landfills overflowing with single-use items, the impact on our planet is undeniable. But while silicone offers some advantages over plastic, it's important to understand the full picture to make informed decisions.

Let's explore the benefits and drawbacks of silicone, compare it with plastic, and suggest some even more environmentally friendly alternatives.

 

What is Silicone?

Silicone is a synthetic polymer made from silica (sand) and other chemical ingredients. It is prized for its flexibility, durability, and resistance to extreme temperatures, which makes it a popular choice for kitchenware, medical devices, and other consumer products. Unlike plastic, silicone is free of BPA and phthalates, which are harmful chemicals often found in plastics.

 

Silicone vs. Plastic: The Environmental Impact

While silicone does have advantages over plastic—such as being more durable and reusable—it is not without its environmental concerns.

The production of silicone is energy-intensive and involves the use of hydrocarbons from fossil fuels. Moreover, silicone is not biodegradable, which means it doesn't break down naturally in the environment. Although it doesn’t degrade into harmful microplastics like conventional plastics, it still contributes to landfill waste if not properly recycled.

 

The Recycling Challenge

Recycling silicone is way more complex than recycling plastic.

It requires specialized facilities, which are not as widespread as those for plastic recycling. Most local recycling programs do not accept silicone, making it challenging for consumers to dispose of it responsibly.

TerraCycle, known for its innovative recycling programs, offers take-back services for certain silicone products primarily used in commercial or industrial settings, such as ear plugs and protective eyewear. However, their consumer recycling program currently does not accept silicone products. Instead, they link to retailer take-back programs for specific items like Stasher bags and Ziploc Endurables, both made with silicone.

 

So, Is Silicone Better Than Plastic?

The answer is "Sort of."

Silicone is better than plastic in terms of durability and reusability, which can reduce the need for single-use items. However, the environmental benefits are mitigated by the challenges in recycling and the energy-intensive production process.

For consumers looking to make the most environmentally friendly choice, it's essential to consider the entire lifecycle of the product, from production to disposal.

 

Exploring Better Alternatives

While silicone may be a step up from plastic, there are other materials that offer even greater environmental benefits. Stainless steel, glass, bamboo, and natural rubber are all excellent alternatives that are renewable, recyclable, and biodegradable.

For example, compostable storage bags made from PLA (Polylactic Acid), like those available here at Earthly Market, provide a sustainable option for food storage. These bags have a limited lifespan but are compostable in industrial facilities, meeting the AS 4736 standard.

These materials often come with their own set of advantages and drawbacks, but they generally have a lower environmental impact than both plastic and silicone


In conclusion, while silicone is a better choice than plastic in many respects, it is not the ultimate solution to our environmental challenges. By considering the full lifecycle impact and exploring other sustainable materials, we can make more informed decisions that benefit both us and the planet.

If you’re passionate about reducing your environmental footprint, consider supporting legislation that promotes better recycling infrastructure and extended producer responsibility programs.

Additionally, stay informed about sustainable materials and make choices that prioritize reusability and proper disposal. Together, we can make a significant impact on reducing waste and protecting our environment.
