Which environmental concern is associated with burning circuit boards?

• A. Not carbon-intensive
• B. Carbon-neutral
• C. Ambiguous
• D. Carbon-intensive

Answer: (D)

Burning circuit boards carries a clear environmental cost because it releases significant amounts of greenhouse gases and hazardous pollutants. The plastics and flame-retardant materials in many boards break down under combustion to produce carbon dioxide and other emissions, while also releasing toxic byproducts such as dioxins and furans. This combination makes the practice carbon-intensive, raising the overall carbon footprint and contributing to air pollution and health risks. It isn’t carbon-neutral, since there’s no offsetting activity that compensates for the emitted CO2, and the issue isn’t ambiguous given the well-documented emissions from burning e-waste.
