A research team from the Graz University of Technology (TU Graz) in Austria and India’s Vellore Institute of Technology (VIT) have been working on the development of 3D-printed imitations of human skin that could potentially be used to replace animals in cosmetics testing.
Directive 2010/63/EU, European legislation “on the protection of animals used for scientific purposes,” laid out restrictions for testing cosmetics and their ingredients on animals in the European Union that have been in effect since 2013.
Since then, scientists have been looking for alternatives for testing the toxicity and absorption of cosmetics such as suntan lotion.
“The hydrogels for our skin imitation from the 3D printer have to fulfill a number of requirements,” said Professor Karin Stana Kleinschek, a researcher with the Institute of Chemistry and Technology of Biobased Systems, in a press release from TU Graz. “The hydrogels must be able to interact with living skin cells. These cells not only have to survive, but also have to be able to grow and multiply.”

The team is working to develop skin imitations that mimic human skin’s natural biomechanics and three-layer tissue structure. The imitations are made up of hydrogel formulations that can be printed along with living cells.
Hydrogels have a high-water content, which provide the ideal conditions for the growth and integration of cells. But the high-water content also means the 3D prints must be mechanically and chemically stabilized.
“TU Graz is working intensively on cross-linking methods for stabilization. Ideally, following nature’s example, the cross-linking takes place under very mild conditions and without the use of cytotoxic chemicals,” the press release said.
Once the prints have been stabilized, the researchers in India test the toxicity and resistance of the 3D prints. Before imitation skin would be able to be developed, however, skin cells from the hydrogel would have to be able to survive for two or three weeks in cell culture before a skin imitation would be able to be produced. The imitation skin could then be used in cell tests on cosmetics.
The first 3D-printed hydrogels tested in cell culture were successful.
“In the next step, the 3D-printed models (skin imitations) will be used to test nanoparticles,” Kleinschek said. “This is a success for the complementary research at TU Graz and VIT. Our many years of expertise in the field of material research for tissue imitations and VIT‘s expertise in molecular and cell biology have complemented each other perfectly. We are now working together to further optimize the hydrogel formulations and validate their usefulness as a substitute for animal experiments.”
The findings of the study, “Protocol for the fabrication of self-standing (nano)cellulose-based 3D scaffolds for tissue engineering,” were published in the journal STAR Protocols.

Curating a conscious home is a thoughtful process involving much consideration — who made my products, how they were made, and what are they made from — and this guide aims to support you on your journey towards finding ethical and sustainable home decor you truly love.
What is Sustainable Home Decor?
Sustainable home decor includes any home decor that is made in a way that takes into consideration both the makers and the planet. Sustainable home decor will be ethically made using eco-friendly and natural materials. Eco-friendly decor will also be produced using sustainable supply chain practices. This includes using renewable energy and recycled or compostable packaging.
While there are numerous sustainable home decor brands, some of which are featured below, first consider what’s already been made in order to prevent contributing to new waste. Secondhand, used, or DIY home decor options are typically more sustainable than buying new.
What is Ethical and Fair Trade Home Decor?
Ethical and Fair Trade home decor is produced in a way that adheres to Fair Trade standards and is, ideally, Fair Trade Certified. Fair Trade means paying artisans and makers a fair, living wage and providing ethical working conditions. Ethical home decor also includes supporting goods made by artisans using traditional heritage techniques and art forms. Many cultures around the world are at risk of losing their age-old artisanal crafts forever in the age of mass manufacturing.
It’s important to note that sometimes a major brand may use an “eco” fiber while still supporting irresponsible labor practices, and excessive production amounts that inevitably lead to a lot of waste. This is not true sustainability in my mind!
Most artisan-made home decor is ethically produced and directly supports the makers. However, it’s important to check if a brand or marketplace is transparent about their business practices to ensure they are ethical or Fair Trade.
Where Can You Find Sustainable Home Decor?
In terms of environmental sustainability, looking secondhand and vintage is always a great first place to look for sustainable home decor.
But if you’ve scoured those options and haven’t found what you’re looking for and/or if you’re looking to financially support artisans and traditional crafts around the globe, this shopping guide is designed for you. You’ll discover many brands with artfully designed and artisan handmade goods for furnishing any space among this list of decor brands.
All of the brands in this guide use natural and/or recycled fibers and avoid the use of virgin synthetics like polyester; however, some brands do use materials that are not the most environmentally-friendly option on the market, such as conventional cotton.
And of course, I wanted to choose brands that followed slow, thoughtful production practices, prioritizing artisan handmade over factory labor and quality over quantity.
So without further ado, here are my favorite small-batch, artisan-made, and ethical home decor brands.

Take a look at why hemp is heralded as a hero material and discover 14 hemp clothing brands that have tapped into its sustainable potential.
The exploration of fabrics has always been a starting point for sustainable innovation in fashion. After all, fabrics provide tangible proof that change is possible while having a direct impact on the environment in one way or another. Plus fabrics are responsible for an outsized proportion of a fashion brand’s carbon footprint and overall environmental impact, including biodiversity loss and pollution.
So, What is Hemp Fabric?
Hemp is a bast fiber produced from the cannabis sativa plant, where every part of the plant can be utilized for over 25,000 industrial uses including clothing, biofuel, bricks, paper, and textiles.
Contrary to its popular association, hemp is actually the sober sister to marijuana. Unlike its recreational sibling that’s grown for its psychoactive THC (tetrahydrocannabinol) properties, hemp contains less than 0.3% THC, a value that was the driving force behind the legalization of hemp production in the 2018 Farm Bill. So while you can’t really get high from hemp, you can definitely enjoy its material benefits — which are plenty!
What is Hemp Clothing?
The simple answer is that hemp clothes are garments made from hemp fabric! But the important caveat here is that most hemp clothes on the market today are not made from 100% hemp fabric. They are usually blended with other fibers, like cotton.
At this point, hemp fabric manufacturing is not at the scale or technological level that the manufacturing of cotton (the most popular natural material) is, making 100% hemp clothing more expensive to produce. Also, pure hemp fabric is also known to be quite stiff until a couple dozen washes later, so blending it with a fiber like cotton can make it softer and easier to wear on the offset.
100% hemp fiber content clothing does exist, it’s just rare at this point. Though we do think this will change with more sustainable material investment happening in the textiles industry.
Is Hemp Clothing Comfortable?
It depends! The softness of hemp clothing will vary based on how the fabric was produced and if it is blended with other fibers like cotton or lyocell. Pure hemp clothing can be rougher than cotton, but hemp is known to get softer with every wash.
Also, since hemp is a natural bast fiber that comes from the softer parts of the plant’s stalk or stem, it is softer than the coarser leaf fibers.
Can Hemp Clothing Protect From The Sun?
A lesser known benefit of hemp clothing is that it can reportedly even help shield you from harmful UV rays. According to skin cancer research, a fabric’s UPF (Ultraviolet Protection Factor) value is a number that coincides with the fraction of UV rays it allows to pass through and hit your skin — the higher the UPF number, the better the protection.
Research claims that hemp has a UPF of >50 (according to European standards) due to natural pigments and lignin within the fibers, which act as UV absorbers.
Is Hemp Clothing Sustainable?
There are a lot of benefits to hemp clothing. But don’t just take our word for it, we’ve listed some of hemp’s most impressive sustainable qualities below:
1. Hemp is not resource-intensive
Hemp can be grown under a variety of agricultural and ecological conditions and has a capacity to grow rapidly.
Hemp clothing vs. cotton: With a high yield of 250% more fiber than cotton, hemp requires less land to grow, has no need for harmful pesticides or chemicals, and needs as little as 1/3rd of the water compared to conventional cotton. (Though individual use cases may vary based on the region that each of the crops are grown.)
2. Hemp is a restorative plant
Growing hemp can also help contribute to the maintenance of soil quality, courtesy of its anchored roots which prevent soil erosion and nutrient loss.
In fact, research shows that hemp can be used to restore contaminated soils through ‘phytoremediation’ — a process that has proven successful in the early 90s when industrial hemp was planted in some of the polluted Ukrainian regions near the Chernobyl disaster where much of the land was rendered useless. The experiments showed that hemp helped remove radioactive elements from the soil.
3. Hemp can absorb carbon more than other plants
Hem can act as a carbon sink. According to a Cambridge University researcher, a hectare of hemp can absorb between 8-15 tonnes of CO2, giving hemp plants a vital role in reversing carbon emissions.
