Bossa’s Mission Saveblue Towards Zero Water

Turkish denim manufacturer Bossa’s misssion is to strive for zero water in their production process. This process is named Saveblue: Towards Zero Water. Recently they achieved to save 85% of water in proportion to the conventional dyeing. Therefore the same amount in wastewater was realized. All the values of the savings was measured and reported by Cukurova University in Turkey.

Effect Of Save Blue

The result of the report by Cukurova University showed that conventional and water saving dyeing (Saveblue concept) applications were carried out under the same conditions in the same warp dyeing machine in Bossa. The process times of both processes were found to be close to each other. After dyeing, cross-sectional images of dyed yarn specimes taken from the selected measuruments were examined. And it was determined that the penetration levels of the dye to the yarn, and therefore the dyeing efficiency were very close to each other at both processes. There was no difference in the fastness washing, water, sweat (ad friction) values of fabrics woven from dyed yarns.

When prescriptions are examined, caustic is not used in the water saving dyeing process, unlike conventional dyeing, which is considered as a positive approach in terms of environmental pollution. With the water saving dyeing process under the name of Saveblue concept in the warp dyeing, it was observed that 87,5% water saving was achieved in proportion to the conventional dyeing. And therefore the same amount of decrease in wastewater was realized.

The visual here below shows the effect of Saveblue technology;

  • 85% saving on water.
  • Pollution on marine water 14,19% less.
  • Global warming: 12,08% less.
  • Pollution on fresh water: 8,06 less.

Effect Of 20% PCRD + Saveblue

In the previous Bossa article you can read about their LCA (Life Cycle Assessment) study. Bossa is running LCA studies with Kahramanmaras Sutcu University Textile Engineering Department. Around 1.000 old pairs of jeans can be used for producing 2.000 meters 20% PCRD (Post Consumer Recycled Denim) blended fabric. In case you have missed this one, please read the full article here.

The visual here below shows the effect of 20% PCRD + Saveblue (This means that 20% Post Consumer Recycled Denim was dyed with a Saveblue dyeing method.);

  • Pollution on fresh water: 18,88% less.
  • Pollution on marine water: 5,82% less.
  • Pollution on terrestirial ecosystem: 19,85% less.
