Denim is one of the most iconic fabrics in fashion. It is also one of the most resource-intensive.

A single pair of jeans can take up to 3,800 litres of water to produce, along with heavy doses of energy and chemicals to achieve certain colours and finishes.

The InTex project is co-funded by the European Union.
