How to Reduce VOC Emissions From Paints and Coatings

Paints and coatings are used in many manufacturing processes and are responsible for a significant amount of VOC emissions, which are regulated under strict environmental laws (e.g., the Clean Air Act).

One of the most effective ways to lower the costs associated with air pollutant abatement in manufacturing is to minimize VOC emissions caused by the use of paints and coatings. Here’s how:
1. Increase Paint Transfer Efficiency
During the spray painting process, a certain amount of paint goes past the target and is wasted, thereby increasing VOC emissions.

By improving paint transfer efficiency, which refers to the amount of paint deposited on […]

Controlling Nitrogen Oxides in the Manufacturing Industry

Nitrogen oxides (NOx) are common air pollutants emitted during many industrial manufacturing processes. Their emission is controlled by the EPA, and manufacturers are required to control the amount of NOx their processes release into the atmosphere.
What Are Nitrogen Oxides?
NOx occurs mostly in the form of nitric oxides (NOx) and nitrogen dioxide (NO2), both of which are corrosive and hazardous to health.

Nitrogen, in its natural form (N2), is an inert gas that makes up 80% of the air. However, as a single atom, it is quite reactive and can combine with oxygen in the air to form a few different […]

    NAAQS Update: Seven Areas At Risk to Be Labeled Serious Ozone Areas

NAAQS Update: Seven Areas At Risk to Be Labeled Serious Ozone Areas

Are you a manufacturer or other producer in or around Chicago, Dallas, Houston, San Diego Nevada County (CA), New York, New Jersey, or Connecticut? You may face new requirements in the coming years pertaining to your emissions levels.

Following a November announcement by the EPA, these areas have failed to attain the 2008 Ozone National Ambient Air Quality Standards by the required date for “Moderate” nonattainment status. What does this mean and how could it affect your business? We explore this in detail below.
Background: National Ambient Air Quality Standards (NAAQS)
Under the Clean Air Act of 1970, the Environmental Protection Agency […]

State Implementation Plans: How Plans are Developed and Enforced Part 1

The Clean Air Act is a complicated set of rules and regulations that affect the way that we commute, produce, and operate businesses across the United States. With so many moving parts and enforcement activities, the process for remaining compliant with location-based NAAQS is challenging for many areas, and it’s on the states to develop plans and initiatives to improve air quality.

As we discussed in our last blog, there are currently seven areas that failed to maintain their classification as “moderate” nonattainment areas for Ozone, as dictated by the 2008 Ozone National Ambient Air Quality Standards (NAAQS). With 2015 […]

    How to Learn More about Your State’s Pollution Control Requirements

How to Learn More about Your State’s Pollution Control Requirements

The United States is built on the idea that different states have different needs, and one-size-fits-all regulations are rarely the best option. With 3.5 million square miles of landmass, varying altitudes, and a wide range of population densities and industries, implementing any massive regulatory change pertaining to air pollution would be implausible and ineffective.

Simply put, applying the same standard to a manufacturer in Iowa and California wouldn’t take into consideration the needs of either business or the community surrounding it. An overarching standard would be too strict for one and too lax for the other and would fail to […]

    The Current and Future Challenges Surrounding Air Pollution Abatement

The Current and Future Challenges Surrounding Air Pollution Abatement

It’s no secret that air pollution is extremely dangerous for both the general public and the environment. This is one of the reasons why the Clean Air Act of 1970 was established in the first place – to help improve public health while reducing the impact humans have on the natural world.

Although the air pollution levels have dramatically decreased over the last 45 years, airborne contamination is still a major issue. Industrial facilities need to abide by regulation set by the Environmental Protection Agency (EPA) when it comes to pollution emissions and their abatement mechanisms.

In this article, we’ll discuss […]

The End of Once-In-Always-In

On January 25, 2018, the EPA issued new guidance on a 1995 memo clarifying the initial stance on major and area sources. Now referred to as the “once in always in” rule, this memo set forth rules for the classification of major sources of hazardous air pollutants under section 112 of the Clean Air Act. The update now allows companies the ability to break away from the legal issues that arise for major sources—if they can prove they have reduced emissions to area source levels.
Background: “Once in, Always in”
Section 112 of the Clean Air Act Amendments of 1990 made […]

The Science of Pollution Control: Destruction Efficiency

As we continue our Science of Pollution Control series, we would today like to look at another important consideration in pollution control: destruction efficiency.
What is Destruction Efficiency?
Destruction efficiency is, in simple terms, the effectiveness to which an oxidizer (VOC Abatement System) works.

Sometimes referred to as destruction and removal efficiency (DRE), this is a percentage that represents the number of molecules of a compound removed or destroyed in an oxidizer relative to the number of molecules that entered the system. (For example, a DRE of 99.99 percent means that 9,999 molecules are destroyed for every 10,000 that enter.
Calculating Destruction Efficiency
As […]

Choosing the Best VOC Abatement System for Food Manufacturers

Since the 1970s, food manufacturing facilities are responsible for controlling their dangerous gas emissions. Volatile organic compounds (VOCs) are some of the most common pollutants food factories and bakeries generate, and can severely hinder the environment if released into the atmosphere untreated.

There are now various VOC abatement systems and technologies available that are suitable for different factories, including food manufacturing and packing facilities. In this article, we will provide you with a few tips on how to find the ideal VOC abatement system for your factory.
Do All Food Manufacturers Need VOC Abatement?
As a rule of thumb, only factories that […]

The CMM Group Releases VOC Abatement Guide

What does new car smell have in common with freshly baked bread? The same thing it has in common with diesel emissions, dry cleaning solution, a can of paint, and a vast majority of manufacturing emissions. All of these are the result of volatile organic compounds (VOCs), carbon-based compounds that exist as a gas in normal temperature and pressure. Many of these compounds are responsible for adverse health, economic, and environmental effects.
Volatile Organic Compounds Pose Threats to Health, Economy, and Environment
While the definition of Volatile Organic Compounds (VOCs) is simple—carbon-based compounds that exist in a gaseous form at normal […]
