Each year on 7 September, the United Nations calls for global awareness and action through the International Day of Clean Air for Blue Skies. First observed in 2020, this day emphasizes the urgent need to improve air quality worldwide. It draws attention to how air pollution impacts human health, productivity, ecosystems, and the climate—especially in vulnerable communities.
The annual theme, such as the recent “Invest in #CleanAirNow”, underlines the importance of shared responsibility, stronger policies, and technological innovation to address one of the world’s most pressing environmental health challenges.
Why It Matters
Air pollution is the second-leading environmental risk factor for premature death, contributing to respiratory diseases, cardiovascular problems, strokes, and cancers. According to the World Health Organization, over 99% of the global population breathes air that does not meet safety standards. The impact is both human and economic—reduced quality of life, lost productivity, and billions in avoidable healthcare costs.
Improving air quality is not just a health priority, it is an economic opportunity. A modest reduction in airborne pollutants can yield significant gains in public health, industrial efficiency, and environmental resilience.
How SteamDry Contributes to Clean Air
At SteamDry, we are not just recognizing the International Day of Clean Air for Blue Skies—we are actively contributing to its goals through innovation in industrial drying.
Our Superheated Steam Drying (SSD) technology is designed for materials such as paper, board, tissue, and nonwovens. It offers a cleaner, more energy-efficient alternative to conventional thermal drying methods, which often rely on fossil fuels and release emissions into the atmosphere.
Key contributions of the SteamDry SSD system include:
- Significant energy reduction: Up to 60% energy savings in the drying section and approximately 40% across the entire production line.
- Substantial emission reduction: SSD can be powered with renewable energy sources and operated with minimal or zero carbon footprint.
- High economic impact: In Europe alone, the technology has the potential to save 127 TWh annually (valued at approximately €6 billion). Globally, savings could reach 870 TWh.
- Digital integration: The system incorporates AI-driven monitoring, digital twins, and smart controls, enabling precision operation with low maintenance and operating costs.
A Key Advantage: Closed-Loop, Emission-Free Operation
One of the defining features of SteamDry’s SSD technology is its closed-loop steam circulation. Unlike traditional dryers that release steam and vapours through chimneys into the atmosphere, our system recirculates superheated steam within a sealed process. This design ensures that:
- No vapour chimneys are required.
- No emissions are released into the air.
- Energy is reused efficiently within the loop.
By eliminating the need for atmospheric discharge, SteamDry’s technology prevents the release of airborne contaminants, including particulate matter and chemical residues. This not only protects the environment but also enhances workplace safety and supports regulatory compliance in emission-sensitive industries.
A Path Forward
The International Day of Clean Air for Blue Skies is a reminder that clean air is a shared resource and a shared responsibility. Technology providers, manufacturers, policy makers, and communities must work together to shift toward sustainable, low-emission solutions.
At SteamDry, we are committed to being part of that shift. Through our SSD system, we enable industries to reduce energy use, cut emissions, and eliminate vapour release into the atmosphere—helping ensure that clean air and blue skies remain within reach for future generations.
Clean air is not a luxury—it is a necessity. As we observe the International Day of Clean Air for Blue Skies on 7 September, we reaffirm our commitment to delivering industrial technologies that make a measurable difference. SteamDry’s closed-loop, emission-free SSD technology exemplifies how clean innovation can support both economic performance and environmental responsibility.
Let us use this moment to invest in cleaner processes, support bold innovation, and take meaningful action—because the future of blue skies begins with the decisions we make today.
