What is a common method to reduce hazardous waste in operations?

• A. Substitution
• B. Recycling
• C. Reuse
• D. Disposal

Answer: (A)

Substitution cuts hazardous waste by replacing one hazardous substance or process with a safer alternative, so less hazardous material is introduced in the first place. This prevents waste generation at the source and reduces overall risk and regulatory burden. For example, swapping a toxic solvent for a safer, lower-toxicity option or reformulating a process to use less hazardous chemicals minimizes the amount of hazardous waste produced. Recycling and reuse handle waste after it’s created and require additional steps to manage or recover materials, while disposal ends the waste without reducing its hazard. Substitution focuses on prevention, making it the most effective way to reduce hazardous waste in operations.
