| Problems with dying and finishing processes that use lots of chemicals | It produces lots of chemical waste Requires energy to drive the machinery Uses and contaminates large volumes of water |
| Solutions to using dying and finishing process that use lots of chemicals | Use natural and cold water dyes (as they require less energy in processing) also reduce the need for very dark dyes Use renewable sources of energy e.g wind Use naturally coloured yarn (to eliminate dying processes) Develop finishing processes so that they do not require as much energy Use fabrics that already have the fabric needed e.g. lyocell is resistant to shrinking |
| What is design obsolescence? | The fashion industry encourages people to continuously update their wardrobe with the latest trends (even though their clothes are still in good conditions). This can be called planned obsolescence or design obsolescence and it generates a vast amount of waste. |
