Genencor, a division of Danisco A/S, introduced in February a new product called PrimaGreen EcoFade LT100, which is a ready-to-use enzyme product for denim bleaching and shading.

This new technology enables bleaching at neutral pH and low temperature, thus providing savings in rinsing water and neutralisation chemicals, and - most importantly - savings in energy.
