## **Core Concept**
The disposal of chemical waste is a critical component of biomedical waste management. It involves the proper handling and disposal of hazardous chemical materials generated during medical procedures and laboratory activities. The goal is to prevent environmental contamination and minimize risks to human health.

## **Why the Correct Answer is Right**
The correct approach for chemical waste disposal under biomedical waste management guidelines typically involves **incineration** or **chemical neutralization**. Incineration is a process that burns the waste at high temperatures, reducing it to ash, gas, and heat. This method is effective for disposing of hazardous chemical materials. Chemical neutralization involves treating the waste with chemicals to neutralize its hazardous properties. Among the given options, **incineration** stands out as a widely accepted method for chemical waste disposal.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Autoclaving is primarily used for disposing of infectious waste by using steam under pressure to kill bacteria and other pathogens. It is not typically used for chemical waste disposal.
- **Option B:** Landfill disposal is generally not recommended for hazardous chemical waste as it can lead to environmental contamination and pose risks to human health.
- **Option C:** This option might seem plausible but given that the correct answer involves a method like incineration or another specific treatment, any option not specifying an appropriate method for chemical waste would be incorrect.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **segregation at the source** is crucial in biomedical waste management. Different types of waste, including chemical, infectious, and sharps, must be separated into appropriate categories to ensure safe handling and disposal. This practice significantly reduces the risk of infection and environmental contamination.

## **Correct Answer:** D. Incineration.
