VOC Limits in Coffee Roasting Facilities
Volatile organic compounds (VOCs) are an important concern in the coffee roasting industry because they can affect the air we breathe. When coffee is roasted, different organic chemicals are released into the air. Some of these chemicals can combine with other substances in the atmosphere and create ground-level ozone and smog. Both ground-level ozone and smog can be harmful to human health and to the environment. Recognizing this, regulatory bodies have established VOC limits in coffee roasting facilities to mitigate these effects. In the European Union, combustion-related emissions are often capped at around 100 mg/Nm³ for carbon monoxide (CO) and nitrogen oxides (NOₓ), while in the United States, NIOSH sets workplace exposure limits for compounds such as diacetyl (5 ppb, 8-hour TWA) and 2,3-pentanedione (9.3 ppb, 8-hour TWA). These limits are set to reduce the amount of VOCs released into the air, making sure coffee roasteries follow safe environmental rules.
By keeping these emissions under control, we can help avoid problems like breathing issues and harm to the environment. Following air quality limits in roasting shops is important to protect the environment and to meet the emissions standards for coffee roasters. If a roastery does not follow these limits, it can face fines and harm its reputation. To stay within VOC limits, many roasteries need to use advanced filters and ventilation systems, as well as cleaner roasting methods. These steps help them follow the rules and also show they care about being responsible and sustainable. Some facilities have recorded diacetyl levels up to 4.7 ppb and 2,3-pentanedione up to 3.9 ppb, which remain within regulatory thresholds, though short-term grinding tasks can briefly raise levels near 10 ppb. By sticking to these limits, coffee roasters help improve air quality and show they are committed to health, safety, and protecting the environment.
