For Zilver, sustainability is a commitment and the only way forward. We are constantly pushing this development further.

We believe that the development of sustainable production methods and consumption habits are the only ways to create a balance in the progress of the World’s economy.

Sustainability is at the core of each decision we make, defining what the future of fashion production will look like.

Zilver is committed to using materials that have a lower carbon footprint and protect biodiversity; to produce garments with high quality and extended life cycles; to support and promote new technologies.


As part of Zilver’s commitment towards sustainability, environmental responsibility and supply chain transparency please see a summary of carefully considered materials used in our collections with notable certifications.

Washing guide

During the lifecycle of clothing, the ‘in-use’ phase has the third highest carbon footprint, after fibre production and processing. The ‘in-use’ phase includes the washing, drying and clothing care.

3 key actions can lower drastically this impact: washing at lower temperatures, tumble drying less often and keeping clothes for longer.

The life span of clothing can be extended through carefully caring for clothing and washing them at lower temperatures

Fibres should be cared for in a specific way as they can react in differently to heat, friction and detergent. Below are some common materials and how they should be washed and dried (information from Fashion Revolution’s Loved Clothes Last Issue #2):



Washing: Always close zips or buttons and turn your denim inside out before washing; If your jeans are not dirty you can freeze them to kill the odor producing germs; Always wash at 30oC

Drying: Flatten, re-shape and hang to dry



Washing: Wash on a cool wash of maximum 30oC to avoid shrinkage that occurs in natural fibers

Drying: Dry flat or hang on a hanger to dry to reduce creases. When ironing, iron when garment is slightly damp or use steam setting


Wool, Cashmere

Washing: Animal hairs should only be washed when absolutely needed; Use a specific detergent for washing woolens and wash on a gentle cycle or hand wash

Drying: If machine washed, reshape whilst damp and dry flat ; If garment has been hand washed, place damp garment flat on a clean towel, roll the towel up and squeeze out excess water


Acrylic, Nylon, Polyester

Washing: Clothes made from synthetic fibers release microfibers when washed and therefore should be washed with a product to catch microfibers such as a Guppy Friend Bag

Drying: Hang dry synthetic garments. Never tumble dry synthetic garments as this weakens and damages the fibers quickly


Clothing care labels contain many symbols communicating the best way to clean the garment. Please always refer to those before washing your garment.

Fashion Industry Carbon Footprint

1. The fashion industry causes 10% of all greenhouse gas emissions; producing more emissions than all international flights and shipping combined.

2. Every second, one garbage truck full of textiles is burned or sent to landfills and three in five items bought are thrown away within a year.

3. Washing one synthetic garment releases about 2.000 plastic microfibres, which enter the ocean and the food chain.

4. It takes 2.700 litres of water to make one cotton shirt. That’s what one person drinks in 2.5 years.

5. Making and washing one pair of jeans emits the same co2 as driving 69 miles.

6. 120 million trees are cut down every year to make clothes and 30% of the rayon and viscose used in fashion comes from endangered and ancient forests.the chemicals degrade soil and pollute water.

7. Up to 16% of the world’s pesticides are used in cotton farming every year.
