Air pollution control equipment
What we did:
Pure Skies pollution control equipment reduced PM2.5 and PM10 about 53% and 49%, respectively, at a chemical industry.
The chemical industry includes producers of commodity chemicals such as organic and inorganic chemicals and industrial gases, and specialty chemicals such as pharmaceutical products and essential oils. While these plants produce essential items that we all use daily, they also create air pollution that can be problematic both for the plant’s employees as well as neighboring communities.
One of Devic Earth’s partners, chemical industry, wanted to improve ambient air quality at one of their plants. The plant was already equipped with the latest air pollution control equipment and followed best practices for management of fugitive emissions.
Despite these measures, air quality measured inside the plant inside was poor. Particulate matter – PM2.5 and PM10 – were 109 and 179 μg/m3, respectively, averaged over one week. This is much higher than what is recommended by the National Ambient Air Quality Standards (PM2.5 < 60 μg/m3 & PM10 < 100 μg/m3) and 5 to 10 times higher than standards of the World Health Organization..
Employees and visitors were exposed to high levels of harmful pollutants which would impact their health and productivity.
One Pure Skies 3000 systems were installed inside the Plant. The installation consisted of one Pure Skies base station and one third party air quality monitors (Airveda Pvt. Ltd., Delhi).
The system was configured to handle particulate pollutants (PM10 and PM2.5) and common pollutant gases (NOx, SOx) across the entire campus of the plant – roughly 50 acres.
Outdoor air pollutant levels were monitored continuously at appropriate locations inside the campus to help the customer understand the efficacy of Pure Skies, as well as to provide real time data for optimizing the smart technology in each Pure Skies unit.
For comparison, a reference monitor run by the state pollution control board located about 3.5 km away was used as the comparison monitor, outside the Pure Skies zone of influence.
The plant manager and EHS head were given secure logins to view their property’s air quality data on a convenient app.
In just six weeks, Pure Skies reduced levels of PM2.5 and PM10 were reduced by 53% and 49%, respectively.
Plant output, number of workers, and local weather patterns remained stable during this period.
Figure 1: Improvements in air pollution levels with Pure Skies at a Chemical Industry. The red and green bars are the Pure Skies-Off (7-days) and Pure Skies-On periods (14-days), respectively. The successive green bars depict the incremental decrease in the levels of the pollutants over 14-day intervals. Data source: 3rd party air quality monitor (Airveda Pvt. Ltd.), pre-calibrated against a reference grade monitor.
Pure Skies is a state-of-the-art technology that ensured that the employees working in the plant breathed clean air at work.
After Pure Skies was powered On, a steady improvement was observed in the air quality (Figure 1).
What’s the value of cleaner air to you and your plant?
Reduced sick days
Cleaner air means a stronger immune system. A study from several of Devic Earth’s customers showed sick days reduce by 11-13% year-on-year after installing Pure Skies!
Worker productivity drops by 1% for every increase in PM2.5 levels by 10 mcg/m3, according to researchers from Columbia University. For a typical factory with PM2.5 levels averaging 100-110 mcg/m3, that’s like watching productivity drop by 6-7%!
Improving air quality index (AQI) to less than 50 improves the productivity of employees by 5-6%, which in turn increases the profitability of the company by 1%, according to a study published in the Harvard Business Review.
If that’s not good business sense, then we don’t know what is!
