Solvent removal: a challenge met

PUSTERLA 1880, a global leader in luxury packaging, places sustainability at the forefront of its production processes, as evidenced by its numerous certifications and ethical commitment.

Printing for the luxury packaging sector requires refined finishes that involve the use of special inks and products. These production processes generate emissions with high concentrations of solvents, requiring careful treatment before release into the atmosphere.

The company faced the challenge of reducing solvent and VOC emissions from its printing plants, in line with increasingly stringent regulations and its own commitment to environmental protection.


A strict approach

PUSTERLA 1880 carefully evaluated various solutions, seeking a system that guaranteed:

Effectiveness and Consistency: Consistent VOC reduction within the set limits over time.

Simple Maintenance: Scheduled and minimal interventions, without dust or dirt emissions.

Reduced Footprint: Optimization of space within the plant.

After careful analysis, PUSTERLA 1880 chose a titanium dioxide photocatalytic filtration system developed by Depurex.

Benefits of photocatalytic filtration

This technology harnesses the combined action of ultraviolet light and titanium dioxide to break down VOC molecules into harmless compounds like carbon dioxide and water.

High Efficiency: Eliminates a wide range of VOCs, even at low concentrations.

Selectivity: Targets only VOCs, leaving other gases in the air unaffected.

Environmental Friendliness: Uses no hazardous chemicals and produces no harmful byproducts.

Low Maintenance: Titanium dioxide filters are robust and require minimal maintenance.

Performances in Solvent Abatement

After 6 months of intensive testing that confirmed its effectiveness, the Depurex system was definitively adopted by PUSTERLA 1880. The system operated for 11 years, with an average of 12 hours of activity per day, ensuring a constant reduction in VOCs and fully meeting the company's requirements. Filter replacements were carried out every six months.

PUSTERLA 1880's experience demonstrates that titanium dioxide photocatalytic filtration is an effective and sustainable solution for reducing solvent and VOC emissions in the printing industry. The company's commitment to minimizing its environmental impact translates into a tangible benefit for health and air quality.
