It was four years in the making, but Jeanologia is ready to unveil a laser solution that replaces harmful PP (potassium permanganate) spray. The new technology, Light PP Spray, will be used exclusively for a year by Jeanologia’s 200 partners in 47 countries representing 40 percent of world production of denim.

The sustainable technology company described PP spray as “the last polluting and harmful technique to the health of workers and the environment.”

PP spray is used to create localized areas of wear on a pair of jeans. The process is done with a spray gun that transforms chemicals into micro-particles that can get absorbed by workers. Precautions are taken, but PP can still cause lung problems. Jeanologia reported that currently two million people work with PP spray.

Jeanologia CEO Enrique Silla described the elimination of PP spray as a “milestone” and said it will transform the process of jeans production in the world. He added, “We´ve managed to replace all hazardous technology techniques for workers and emissions of the textile industry that, in the last four years have been reduced to zero percent.”

Jeanologia will showcase Light PP Spray at Denim by Première Vision Barcelona (Nov. 18-19). The company is also inviting attendees to visit its Eco Consulting space at the show for free and personalized advice on ways to make denim production a more sustainable, efficient, automated and transparent process.
