Beyond that, afterburners may also be susceptible to fires due to the high operating temperatures.

Notably, some afterburners may use twice as much gas as the roaster itself.

While an afterburner helps roasters reduce smoke, the gas used to run the machine also creates a carbon footprint.

From an environmental and sustainability perspective, it may not be as ideal, as it is simply displacing the roaster��s carbon footprint from one point to another.

Some afterburners may even reduce 90-95% of the visible smoke and odour from a roastery. However, the technology is a controversial topic within the industry, as some wonder if it is entirely effective in reducing the carbon footprint of the roasting proc

If the beans are exposed to air pollutants and smoke, they may have smoky-tasting notes that affect the overall quality of the cup.

Nearly all the VOCs and smoke particles are reduced to carbon, leaving virtually no visible smoke or odour.

Essentially, an afterburner oxidises the waste gases from roasting and uses a combustion process to generate ��cleaner�� emissions.

Ideally, these pollutants should be treated separately away from the coffee drum.

Carbon dioxide also contributes to global warming because it builds up in the atmosphere, which traps heat and causes the temperature of the planet to rise.

These fumes consist of several volatile organic compounds (VOCs), including diacetyl, 2,3-pentanedione, and other less harmful chemicals, along with carbon dioxide and carbon monoxide.

Meanwhile, the smoke and odour produced during a roast are combinations of organic constituents volatised at roasting temperatures and steam produced when the roast is quenched with water.
