How do garbage and rubbish differ in solid-waste management?

In the context of solid-waste management, both garbage and rubbish are classified as refuse, which refers to nonhazardous solid waste requiring collection and transport to a disposal or processing site.12

The primary difference between the two lies in their composition and decomposition properties:

• Garbage: This consists mostly of food or yard waste. It is highly putrescible, meaning it is organic material that decomposes readily.12
• Rubbish: This is composed primarily of dry, non-putrescible materials such as glass, paper, cloth, or wood that do not readily decompose.12

While some forms of rubbish are recyclable, garbage is often managed through composting or other biological treatment methods. It is important to note that "trash" is a distinct category of rubbish that includes bulky items—such as old furniture or large tree stumps—which often require specialized collection and handling.132
