What is a direct outcome of effective waste segregation at the source?

• A. Increased disposal costs.
• B. Reduced treatment costs and minimized risk.
• C. Increased risk of cross-contamination.
• D. No change.

Answer: (B)

Segregating waste at the point of origin ensures that contaminated, regulated biomedical waste is kept separate from non-contaminated waste, so it can go through the appropriate, often more costly but necessary, treatment process. When this segregation is done correctly, the amount of waste that requires expensive treatment is minimized, which lowers treatment costs. At the same time, keeping infectious or hazardous waste separate reduces the chance that people or other waste streams come into contact with contaminants, thereby minimizing cross-contamination risk.

If disposal costs were the direct outcome, that would imply segregation isn’t effective, since mixed or mis-sorted waste usually drives up disposal and treatment expenses. A heightened risk of cross-contamination would occur if contaminated waste were not properly separated, so that option contradicts the benefit of proper segregation. Finally, saying there’s no change ignores the impact on how waste is treated and disposed, which does change with proper segregation.
