Is burning circuit boards from e-waste carbon-intensive?

• A. False
• B. Not carbon-intensive
• C. It depends
• D. True

Answer: (D)

Burning e-waste is carbon-intensive because burning the plastics and organic materials in circuit boards releases a lot of carbon dioxide as they oxidize. Circuit boards contain hydrocarbon-rich plastics and resin binders; when they burn, these components convert to CO2 and other greenhouse gases, often with little control over emissions in informal settings. This makes the process a high-carbon method of managing e-waste, contributing significantly to the carbon footprint compared with recycling or other safer disposal approaches. While some specialized facilities can recover materials or use energy from combustion, the act of burning itself typically involves substantial greenhouse gas emissions, which is why it’s considered carbon-intensive.
