As industries worldwide strive to reduce their carbon footprint, procurement officers and engineers are re-evaluating their material choices. The shift away from single-use plastics is accelerating, and silicone tubing is emerging as a leading sustainable alternative.
But is silicone truly eco-friendly? Unlike plastics derived from crude oil, silicone starts its life as silica (sand). However, its environmental value goes far beyond its origin.
In this article, we analyze the sustainability profile of silicone, compare it with traditional plastics like PVC, and explain why choosing Silicone Tubing is a smart move for both the planet and your long-term operational costs.
The first argument for silicone’s sustainability lies in its chemistry.
Abundant Origin: The backbone of silicone is silicon, an element derived from silica (quartz sand), which is the second most abundant element in the Earth's crust. This contrasts with plastics, which are derived from finite fossil fuels.
Non-Toxic Nature: High-quality silicone does not contain harmful chemicals like BPA, phthalates, or heavy metals. When you use food grade silicone tubing, you are using a material that does not leach microplastics or toxins into the water or soil, even when exposed to heat.
The most significant environmental benefit of silicone is its longevity. In the hierarchy of waste reduction, "Reuse" ranks higher than "Recycle."
The "Throw-Away" Culture vs. Silicone: A cheap PVC tube might crack or stiffen after a few months of outdoor exposure or heat cycles, requiring replacement. This generates waste.
Built to Last: Silicone tubing withstands UV radiation, ozone, extreme heat (-60°C to 200°C), and harsh weather without degrading.
The Result: One high-quality silicone hose can outlast multiple plastic replacements. This drastically reduces the volume of waste sent to landfills over the lifespan of a machine.

To understand the difference, let's look at a direct comparison between Silicone and common plastics (like PVC).
Feature | Silicone Tubing | Plastic Tubing (e.g., PVC) |
Source Material | Silica (Sand/Quartz) | Crude Oil (Petroleum) |
Lifespan | Long (Years/Decades) | Short (Often single-use or months) |
Microplastics | Does not break down into microplastics | Breaks down into harmful microplastics |
Incineration | Burns into amorphous silica (sand), CO2, and water vapor | Can release toxic chlorine gas and dioxins |
Chemical Leaching | Inert (Safe for Medical/Food) | May leach phthalates/plasticizers |
Choosing the right material contributes to a greener supply chain.
In healthcare, the trend is moving towards safer materials. Medical grade silicone tubing is biocompatible and can be sterilized (autoclaved) repeatedly. This reusability in certain device applications reduces the staggering amount of medical waste compared to single-use PVC consumables.
For breweries and dairies, hygiene is paramount. Food grade silicone tubing does not harbor bacteria and withstands harsh cleaning cycles (CIP), meaning the same tubing can be used safely for longer periods, reducing the material turnover rate.
This is a common question. While silicone is not biodegradable (it doesn't rot like an apple), it is recyclable.
Specialized Recycling: You cannot throw silicone in your curbside bin, but specialized recycling facilities can break down silicone into silicone oil, which is then used as a lubricant or industrial ingredient.
Safe Disposal: If silicone is incinerated at a waste facility, it does not produce toxic fumes. It reverts to silica, carbon dioxide, and water vapor—a much cleaner burn than chlorinated plastics.
Sustainability is about making smarter choices. While silicone tubing may have a higher initial cost than cheap plastic, its extended lifespan, safety profile, and non-toxic properties make it the superior eco-friendly investment.
By choosing high-quality silicone, you are not just buying a tube; you are investing in a cleaner, safer, and more efficient future.
Q: Is silicone tubing biodegradable?
A: No, silicone is not biodegradable. It does not decompose in the environment. However, this is also its strength—it does not break down into microplastics causing pollution. It should be recycled at specialized facilities.
Q: Is silicone better for the environment than plastic?
A: Yes, generally. Silicone is more durable (reducing waste), derived from abundant sand (not limited oil), and does not release toxic chemicals when incinerated, making it a more sustainable option than most plastics.
Q: Can I recycle my old silicone tubing?
A: Yes, but not in your home recycling bin. Many manufacturers and specialized recycling centers accept silicone waste to downcycle it into industrial lubricants.
Q: Does manufacturing silicone hurt the environment?
A: Like all industrial processes, it uses energy. However, because silicone lasts significantly longer than plastic, the "energy cost per year of use" is often lower.
