About Ozone Bleach

How positive is Ozone Bleach for the environment?

Let’s find out to what extent CO₂ can be reduced relative to the conventional scouring and bleaching process. (Note that the amount of energy required for ozone bleaching is limited to the amount of energy necessary for ozone’s decomposition.)

Setup: cotton yarn: 1kg, water: 10 liters.

• With a conventional scouring and bleaching technique : To process 1kg cotton yarn, approximately 8.28MJ of energy is necessary. Volume of CO₂ emissions: - 800g
• With the Ozone Bleach technique : To process 1kg cotton yarn, approximately 3.13MJ of energy is necessary. Volume of CO₂ emission: - 400g

Ozone Bleach enables a reduction of CO₂ emissions by roughly 400g per 1kg cotton yarn, equivalent to roughly 50% reduction from the CO₂ emissions of the traditional scouring and bleaching technique.

Factoring the product weight into the formula above yields a figure for the magnitude of reduced CO₂ emission per product, which manufacturers can disclose for promotion purposes.
