Negative effects of coffee roasting you may not know?
Every link in the coffee production and supply chain can make the coffee trade more sustainable or cause negative impacts on the environment and communities. But often, we are focusing more on the farm, the coffee shop and accidentally forget the influence of the roaster. Although it is only a prevention step, the environment can still be affected by the negative impacts of the coffee roasting process. Let’s find out with XLIII Coffee!
Roasting coffee causes pollution and affects human health
According to one study, the stages of coffee roasting and packaging account for 15% of the total carbon emissions on the journey from the farm to the tasting table. For roasters, coffee roasting accounts for 79% of the carbon dioxide (CO2) emissions of their business. Because coffee roasting is an energy-intensive process and emits a large amount of solid waste when burned. In addition, roasting coffee produces carbon monoxide, smoke, fine dust, and other toxic volatile compounds that escape from the air ducts connected to the roasting cage. These gases released into the surrounding environment are easily spread to neighboring areas, polluting the air, affecting the health of roasters and surrounding people. Especially carbon monoxide is the leading cause of dangerous respiratory diseases.
Not stopping there, many roasters use natural fuels combined with ventilation systems that cause all harmful gases to disperse into the atmosphere quickly. These emissions accumulate causing an increase in the concentration of greenhouse gases of the earth (CO2, methane, …) leading to higher global temperatures. This leads to a rapid increase in ice at the poles, breaking some natural laws, and affecting the habitat of humans and creatures on Earth.

How to reduce emissions during coffee roasting
One of the methods most used by roasters is to invest in a more sustainable machine to cut emissions during the roasting process. A new machine using thermal circulation technology will help reduce gas consumption and reduce emissions optimally. Many roasters today also incorporate patented vortex and balance systems that allow for more stable roasting profiles. Installing these systems makes it possible for roasters to comply with all emissions rules and regulations and reduce consumption, says the production engineer at coffee roaster maker IMF, Lorenzo Mosca. more energy. Furthermore, switching from a more traditional roaster to a newer one can have a big impact on the roast profile. This can cause roasters to dramatically change the way they roast their coffee. However, for smaller roasters, paying the upfront cost of buying a new machine can be a challenge.
In addition, roasters can reduce their carbon footprint by adjusting their roast profile. Emission levels tend to be higher when you roast at higher temperatures or with a darker roast profile. Therefore, a light roast instead of medium or dark is also a good solution.

As the brand that provides specialty coffee XLIII Coffee, in addition to using a modern roaster, it also chooses an Extremely Light roasting level for all coffee lines. Roasting mode with a temperature not exceeding 194 degrees Celsius, ends as soon as the first crack appears to save energy consumption and minimize emissions into the environment. Moreover, this roasting method fully preserves the inherent characteristics of high-quality coffee beans. From there, when preparing, each drop of flavor imbued with the identity of the growing area is allowed to spread to diners the most authentic experience.
