If you’re into slow-fashion or high-quality materials, you may be wondering: is alpaca wool sustainable?
Alpaca wool is a relatively sustainable fiber when responsibly sourced, due to the animal’s low-impact grazing, the fiber’s durability, and its biodegradability. However, sustainability ultimately depends on land management practices, production methods, and consumer behavior.
Let’s dive into the reasons why alpaca wool is sustainable—and the challenges to ensure your future garment is, too.
Alpacas Have a Low Environmental Footprint
The Argument
A herd of alpacas is more gentle on the Earth than sheep or goats. There’s several reasons for this:
-
Alpacas have softer hooves thanks to their soft-padded feet
-
Alpacas nibble grass, rather than uprooting it.
-
Alpacas are water-efficient and require less food than cattle or sheep.
The reason why alpacas consume less water and food is because of their origins: bred in the Andes, alpacas have evolved to match the harsh environments and are therefore energy-efficient little fellows.
The Challenge
Environmental impact largely depends on herd size. Large herd sizes can still cause land degradation. Additionally, overgrazing, poor land management, and even low water and land use still have an environmental impact.
The Final Verdict
-
Alpaca wool is generally sustainable and has a lighter footprint than most livestock.
-
When managed responsibly and herd sizes stay small, it is obviously more sustainable than is the case for large-scale production.
-
Being more resource-efficient is a valid advantage over other fiber-producing livestock.
Alpaca Wool is Naturally Biodegradable
The Argument
Pure, 100%, unblended, undyed alpaca wool breaks down naturally at the end of its life cycle, reducing landfill waste compared to synthetics. Just like any natural fiber, biodegradability is a highly favored feature when it comes to sustainability.
And the alpaca's got it because additionally, it comes in 22 natural shades. This eliminates or reduces the need of dyeing.
The Challenge
Only undyed, untreated, and non-blended alpaca wool is fully biodegradable. And being a brand of alpaca wool products, I have noticed that color variation is what makes products unique and appealing to customers.
When alpaca wool is dyed, it is most often done chemically and it is no longer biodegradable.
Additionally, many commercial products include synthetic blends to lower the cost and that also hinders biodegradability.
The Final Verdict
-
Alpaca wool is biodegradable when fully natural, undyed, and untreated.
-
Commercial products might use chemical dyes to make products more aesthetically pleasing.
-
Natural dyes are available, they just won’t be as bright and are not as largely available.
-
If biodegradability is important to you, stick to natural tones only.
Alpaca Wool is Durable and Long-lasting
One of my favorite features of alpaca wool is that it is incredibly strong. With the right care, alpaca wool products can last for decades. And in terms of slow-fashion, alpaca wool checks all the boxes:
-
Long-lasting
-
Resists pilling
-
Doesn’t lose its shape
-
Is emotionally durable (which means you’ll love it longer)
Basically, alpaca wool looks good for a long time and this reduces clothing turnover.
-
Bonus Points: Because of this, you will find lots of alpaca wool in vintage or thrift stores—whenever I see a label that says 100% alpaca wool, I basically buy it without even thinking about it :)
The Challenge
However much I love my alpaca wool garments, longevity depends on many things, like garment quality, user care, and fashion relevance. Durability doesn’t ensure sustainability if the product is unused or discarded early.
The Verdict
-
High-quality garments are more durable than most, promoting slow fashion.
Alpaca Wool Requires Minimal Chemical Processing
Alpaca wool lacks lanolin, the natural wax found in sheep wool that makes it greasy and water-repellent. Removing lanolin from sheep wool typically requires scouring—a water- and energy-intensive process that often uses harsh chemical detergents and alkaline agents.
Alpaca fleece, on the other hand, is much cleaner upon shearing:
-
It contains less oil and fewer contaminants, so it doesn't need heavy scouring.
-
It can be cleaned with mild soap and water, reducing chemical and water use during processing.
Additionally, because alpaca is hypoallergenic, it doesn’t require treatment to reduce allergens (another chemical step often applied to sheep wool).
The Challenge
Some industrial production still uses chemical detergents and dyes, and even natural wool needs water and energy for processing. So while alpaca possibly doesn’t need synthetic detergents, it doesn’t mean that industrial-scale alpaca mills won’t use them.
And when chemical detergents, dyes, and finishing agents are used, chances are that water pollution from dyeing and processing happens next.
The Verdict
-
In essence, alpaca wool doesn't requires less chemical processing due to it’s natural cleanliness and hypoallergenic features.
-
However, sustainability depends more on the producer than the fiber itself.
-
Certified producers will adhere to standards like GOTS (Global Organic Textile Standard), natural or plant-based-dyes or closed-loop systems.

Alpaca Wool Is Odor- and Stain-Resistant and Requires Less Washing
The list of amazing-alpaca-features goes on: it’s also breathable, naturally odor-resistant, and less prone to staining, which help keep the fibers dry and free from the bacteria that cause odor. The result is that it’s more effective at staying fresh, even with less frequent washing.
The natural fiber structure wicks away moisture (like sweat or oils) that can lead to unpleasant smells. Because moisture doesn’t stay trapped within the fibers, bacteria, which are often responsible for producing body odors, have less of a chance to thrive.
The Challenge
Alpaca wool is great at resisting odors, but it’s not perfect. Everyone’s body chemistry is different, so some people might still notice odors. If the wool gets exposed to a lot of moisture or sweat and doesn’t dry properly, odors can build up.
Also, lower-quality alpaca wool may not perform as well, and it can still pick up external smells like smoke or food. While it’s more resistant to odors than many fabrics, it’s not totally odor-proof.
And while alpaca wool allows for less frequent washing, it still needs care, and laundering still contributes to water and energy use.
The Verdict
-
Reduced washing is a benefit.
-
Alpaca wool can resist odors better than many other fibers, especially synthetics, but isn’t immune to them.
-
Frequent or intense moisture exposure may still lead to odor buildup, and low-quality alpaca wool may not perform as well.
The Final-Final Verdict
What I love about alpaca wool is that while it might not be perfect, it’s so much better than many other fibers, while being reasonably accessible (= available + affordable). It’s not flawless, but in terms of eco-friendliness, it outshines many alternatives.
- It’s biodegradable, requires fewer chemicals, and lasts longer, which means fewer resources used over time. Plus, it needs less washing, reducing water and energy use.
Of course, so much depends on how it’s produced—and luckily, we happen to be working with one of the good ones. Our producer is GOTS-certified and deeply committed to sustainable practices.
