When you think about how to find sustainable clothing manufacturers, request the following 3 things from any potential supplier you get in contact with:
- Certificates for the fabrics (OEKO-TEX, GOTS, GRS)
- Social responsibility certificates (SA8000, SMETA, BSCI)
- Factory visits
It goes without saying that to be really sustainable, factories you work with must be ethical clothing manufacturers. Don’t forget, sustainable fashion = ethical fashion. There must be no child labour or forced labour at your potential suppliers’ factory(ies).
Here’s a short and sweet pdf infographic that can help you understand the how is sustainability achieved at FUSH.

You don’t want to find this scenario in the factory that makes your clothes so make sure you inspect the factories of your potential partners before doing business.
What better way to check if FUSH is a sustainable clothing manufacturer than to send us an enquiry through the easy-to-fill contact form at the bottom of the page?
Additionally, you should keep an eye on the emerging sustainable trends in the industry.
The sustainability of any clothing brand begins with its supply chain. Therefore, in order for you to have a sustainable clothing brand, you must work with sustainable clothing manufacturers. They would definitively use materials that contain no toxic chemicals. OEKO-TEX certificates are solid proof of that.
OEKO-TEX-Certified Yarns, Fabrics, and Inks – Pillars of Sustainable Clothing Manufacturers
If you find a clothing factory that has OEKO-TEX certificates for their yarns, haberdashery (sewing notions in US English), dyes, and dye sublimation inks, you’re on the right tracks.
Having this certificate ensures that no toxic chemicals are present in the final product. Learn more about the OEKO-TEX Standard 100.
FUSH has this certificate for all of the above. If OEKO-TEX certification is your principal sustainability concern, send us an enquiry.
Certificates that Guarantee Recycled and Organic Fabrics
Recycled Fabrics
The clothing factory should be able to provide you with GRS certificates for the fabrics they are either sourcing or making. If they‘re taking care of fabric production, they should have GRS-certified yarns.
The GRS certificate ensures that the yarn, and as a result, the fabric is made from recycled plastic. This is very important if you’re looking for activewear manufacturers. That’s because they will use more polyester fabrics than other suppliers.

GRS transaction certificate that shows we at FUSH buy yarns made from recycled polyester. We use that yarn to make our own recycled polyester fabrics.
Organic Cotton Fabrics
In the same vein, you should insist that the factories you plan to work with have GOTS certificates. These certificates are proof that they actually use organic cotton yarns and/or fabrics.
We as sustainable clothing manufactures have all 3 certificates when it comes to the yarns and haberdashery we use. More about that further down the reading path.
The next issue to tackle is sustainability when colouring (dyeing or printing) the garments.
Sustainable T-Shirt Printing and Dyeing
This is a tricky thing to accomplish. If you want to apply colour to a garment made of recycled polyester sustainably, you‘d want to go for sublimation printing.
That’s because dye sublimation printers use next to no water. Also, they don‘t use a lot of electric energy to work. Neither do sublimation calenders that transfer the ink from paper onto the fabric.
Compared to traditional dyeing methods, you’ll save around 100 l of water for one t-shirt!
Plus, a garment colour won‘t fade away as quickly as it does with the traditional water-chugging dyeing method.
Sadly, natural fibres don’t work well with dye sublimation. Dyeing cotton and similar yarns and fabrics is much trickier to do in an eco-friendly way.
So, if you want to go for sustainable t-shirt printing, do so carefully. Make sure to use recycled yarns and make sure to create garments that can be worn for a long time. Also, promote upcycling by giving discounts for returned goods.
FUSH and dye sublimation printing go hand in hand.
In fact, we were one of the few companies in the world that got to test an Epson dye-sub printer before its official release. We’re talking about the first printer that’s able to print fluorescent colours – Epson SureColor SC-F9400H.

We were the first company in Europe that had the privilege to test this machine before its official release in early 2020.
If you really want to do dye sublimation 100% sustainably, avoid white colours in your designs. That’s because the white ink for dye sublimation printers doesn’t exist. And the only way to get that white colour on your garments is through the traditional water-chugging dyeing method.
Follow the Emerging Trends in Fabric Dyeing
Keep an eye on sustainable (but still costly) dyeing technologies presented by companies like DyeCoo and ColorZen.
Puma with their Design To Fade project has been doing something towards achieving this goal when it comes to non-synthetic clothes. That can inspire you.
Also, follow the work of companies like AlgiKnit, GreenDyes, and Wearaware to find sustainable ways of making and dyeing clothes.
Basically, when it comes to innovation in the fashion industry, keep your eyes peeled.
At the moment, the only really sustainable dyeing option we can provide you with is dye sublimation printing.
On the bright side, we have the dye-sublimation printers that use fluorescent inks. Applying fluorescent colours by the means of dye sublimation wasn‘t possible until January 2020. So that‘s some good news.
Sustainable Clothing Factories
Sustainable fashion brands from Europe should rely on sustainable fashion factories from Europe.
With that in mind, you‘d be happy to find that FUSH has 2 factories in Serbia. One in Belgrade and one in Oraovica. There‘s something sustainable about each of those clothing factories.
Don’t forget that clothes with the Made in Europe label have a greater selling potential. Also, working with us as custom clothing manufacturers will further help your brand to stand out in a positive way.
The Sustainable Clothing Factory in Oraovica
Sustainable practices at the Oraovica plant are:
- Wastewater treatment plant
- OEKO-TEX and GRS/GOTS-certified yarns
- OEKO-TEX-certified inks
Wastewater Treatment Plant at FUSH
Our Oraovica apparel factory is located in a rural area and it‘s not connected to the sewage system. Before our arrival, the only solution for wastewater was a big cesspool accompanied by a weak sewage pipe network.
We didn’t want to continue that harmful practice that has a great potential of contaminating the groundwater. That’s why we opted for a wastewater treatment plant.

Early stages of setting up this magnificent machine.
Introducing RotoClear 40 PE
For this technology, we’ve put our trust into the Slovenian company ROTO and their model RotoClear 40 PE. The abbreviation PE stands for Population Equivalent and it refers to household-24/7-use.
With our current production and number of staff, this machine can easily operate at its optimum.
Going One Step Further – Using the Good Bacteria
We’ve taken additional precautionary measures by using a product for the increased decomposition of organic waste called Bistrol. It is a mixture of aerobic and anaerobic saprophytic bacteria that breaks down proteins, cellulose, fats and oils.
That way, the wastewater leaves the RotoClean collectors completely safe for the environment.
This wastewater treatment plant is officially certified by PIA, an accredited and notified testing body for the certification of wastewater treatment products.
Here’s the pdf file with the certificate for all of you in need of further proof.
The easiest way to open pdf files is to set Chrome as the application that opens them.
Also, the entire factory uses LED lighting only. This is true for the Belgrade factory too.
OEKO-TEX and GRS/GOTS-Certified Yarns
We buy recycled polyester yarns from a reputable Taiwanese company Far Eastern New Century are both GRS and OEKO-TEX certified. Consequently, so are the fabrics we manufacture.
We buy organic cotton yarns from a reputable Turkish company UZ Pamuk AS. All of their yarns come with a GOTS certificate.
OEKO-TEX-Certified Inks
For all of you interested in making sportswear, you’ll most probably end up using fabrics made from recycled plastic bottles.
To make sure the entire product stays certified, we use OEKO-TEX-certified inks for our dye-sublimation printers.
We strongly suggest you go for dye sublimation as a dyeing method for your sustainable clothing line. Not only because of OEKO-TEX but because less water would be used in the fabric colouring process.
The Sustainable Garment Factory in Belgrade
The Belgrade factory buzzword is upcycling. This is where we achieve that extra step as sustainable clothing manufacturers.
As most of the fabric cutting is done here, a lot of potential textile waste is created. So, instead of going straight into the landfill, all our “textile extras” end up at 2 places:
NURDOR
NURDOR is a national association of parents of children battling cancer made up from parents, doctors, medical staff, legal advisors, and volunteers.
Our textile trimmings are a regular part of NURDOR’s Love and Hope camps. That’s where mums get to express themselves through art. Mums use our textile cut-offs to make lovely handcrafted goodies like necklaces and wristbands. This is a small contribution but a very dear one because it is for a great cause.
Necklaces and wristbands made at the NURDOR Love and Hope camp. FUSH fabric trimmings are the material that was used to make these works of art.
Iron Sport
Iron Sport is a Serbian sporting equipment manufacturer that is specialised in making boxing gear.
And they need a constant supply of our textile cut-offs in order to make fillings for their boxing bags. Basically, we can make a lot more “textile extras” and they would still be upcycled by Iron Sport in no time. Thanks for helping us maintain our sustainable clothing manufacturers status, Iron Sport!
Visit Our Clothing Factories
We believe that the best way to ensure a clothing manufacturer does its business sustainably is to see it for yourself.
Even though now is not the best time for visits due to the pandemic, we usually encourage our clients to visit us. Both the existing ones and the potential ones.
Especially since we’ve equipped 4 apartments to welcome up to 16 visitors. Those apartments are built right on the factory grounds in Oraovica.
As far as manufacturing services are concerned, here’s what we offer:
