12 Best Cause Tshirts


You might not think that sustainable cause tshirts are all that important, but they actually play a big role in protecting the environment. Traditional cause tshirts are made from cotton, which is a very water intensive crop.

Cotton farming uses huge amounts of pesticides and water, and it also takes a lot of energy to grow and process the cotton. Sustainable cause tshirts are made from sustainable materials like bamboo or organic cotton.

These materials use much less water and energy to produce, and they don’t require the use of harmful chemicals. sustainable cause tshirts also last longer than traditional tshirts, so you’ll save money in the long run.

And of course, sustainable cause tshirts are better for the environment. So next time you’re shopping for a new shirt, consider choosing a sustainable option. It’s better for the planet and your wallet.

The next time a friend or family members birthday comes up think about getting them a sustainable cause tshirt and share stories of social impact with them. Below are some sustainable cause tshirts support amazing missions.

Mi Terro – Logo Tee

Mi Terro is a biotechnology company that reengineers leftover milk into sustainable fibers that can replace plastic in the fashion, medical and packaging industries.

Mi Terro rescues excess milk from its dairy farm partners, skims it to remove fats before dewatering it to turn the liquid into powdered milk. It is then dissolved once again and purified to remove the bacteria, or the so-called ‘bad’ casein, from expired or spoiled milk. Casein makes up 80% of milk protein.

Once the ‘bad’ casein is removed, the remainder protein is spun through a spinneret to solidify it into fiber. The fibers are then stretched and spun into yarn for clothes manufacturing, but, according to Luo, can be also used in bed linen, food packaging, face masks, or toilet paper.

The first version of the milk-to-clothing process took about two months to complete, with one glass of milk making up five T-shirts. The company is currently developing the second version of its milk waste fiber, which they claim requires 60% less water than organic cotton, and is 100% biodegradable.

Repurposing milk waste into clothes is not Mi Terro’s first foray into sustainable fashion – the team has previously designed a travel bag made from ocean plastic and cork.
