Solid waste refer to anything that goes out in trash.

Answer

**Step-by-Step Solution:**

1. **Understanding Solid Waste**: Solid waste is defined as any garbage or refuse that is discarded. This includes various types of waste generated from different sources.

2. **Legal Definition**: The definition of solid waste is provided by the Resource Conservation and Recovery Act (RCRA), which was enacted in 1976. This act outlines what constitutes solid waste.

3. **Types of Solid Waste**: According to RCRA, solid waste can include:
- Garbage or refuse from households.
- Sludge from wastewater treatment plants.
- Waste from air pollution control facilities.
- Discarded materials from industrial, commercial, mining, and agricultural operations.

4. **Clarifying Misconceptions**: The statement "solid waste refers to anything that goes out in trash" is misleading. Not everything that is thrown away is classified as solid waste under RCRA.

5. **Conclusion**: Therefore, the statement is false. Solid waste has a specific definition and includes various types of waste from designated sources, not just anything that is discarded.
