What is the most appropriate method for treating solid waste containing about 4% pharmaceutical residues?

• A. incineration in a single-chamber incinerator
• B. incineration in a pyrolytic incinerator
• C. burial at sanitary landfills
• D. wet thermal process coupled with chemical disinfection

Answer: (B)

Destruction of hazardous organic residues requires high-temperature, controlled thermal treatment to break down complex pharmaceutical molecules rather than simply isolating them. A pyrolytic incinerator provides a high-temperature, oxygen-controlled environment where organic compounds can be broken down through pyrolysis and then fully oxidized, giving very high destruction efficiency for pharmaceuticals. This minimizes residual organics and reduces emissions with proper gas cleaning, making it more effective than a single-chamber incinerator, which risks incomplete combustion; burial in landfills leaves the compounds to leach into the environment; and a wet thermal process with chemical disinfection is less reliable for effectively destroying solid pharmaceutical residues.
