There are different wastestreams that you can use when you're going into the recycling game. The easiest are the fibres and pieces of fabric lost in production. During spinning, dyeing and weaving of the yarns and cutting of the fabrics, waste is created. We use these wasted fibres to spin new yarns and weave them into fabrics. Using these kind of waste streams, lets us move towards a no-waste production process!
Post-Consumer Recycled Denim (PCRD) fibres are a bigger challenge. You need to shred the old denims until they are back to fluffy cotton like fibres. Shredded fibres tend to be shorter, so they are mixed with virgin (organic) cotton to guarantee a high-quality denim yarn and fabric. The challenge is that you need to guarantee a high cotton level in the collected jeans to create a strong fabric. You also need to take out all the metal parts before you can turn the jeans back into fibres.
