Cutting waste (fabric, wadding) mainly contains polyester and polyamide materials. There is pattern paper among the waste, and the material has a non-toxic water repellency treatment according to standards. Dust is created when dust, dander, grease, and animal proteins are removed from the down during the washing process. The trash feather and impurities fraction consist of feathers that are too large and impurities (e.g., small stones) that are not suitable for down products.
Feather and impurities fraction as well as dust are very light, so the volume of generated waste is large. A dust bag with a volume of 0.7 m3 weighs approx. 25 kg, and a 130-liter dust bag approx. 2–5 kg. The feather and trash fraction comes in different colors, white, gray, and varied color mix.
Joutsen Finland oy's factories are located in Riihimäki, Finland and in Märjamaa, Estonia (approx. 70 km from Tallinn). Most of the side streams of the production are generated in Estonia (in Finland approx. 0–200 kg/year of cutting waste, approx. 50–100 kg/year of waste feathers and trash and approx. 500 kg/year of dust from feather processing).
The goal of the Hackathon is to find one or more partners who would be able to regularly receive materials generated as a side stream of textile production. Possible uses of the materials could be, for example, utilization in insulation, bedding, as filling material or, for example, in fishing equipment. So, there are many possibilities even outside the textile industry, and the solution to utilizing the material may be found in a completely different industry.
