**Explanation:**

Municipal solid waste refers to the waste generated by households, institutions, and businesses in a community. It includes everyday items such as packaging materials, paper, food waste, and other similar materials. However, metals scrap is not considered as municipal solid waste. Here's why:

**Metals Scrap:**
- Metals scrap refers to discarded or unwanted metal materials that can be recycled or reused.
- It includes items such as old appliances, car parts, metal furniture, and other metal products that have reached the end of their useful life.
- Metals scrap is not considered municipal solid waste because it is not generated by households, institutions, or businesses on a daily basis.
- While metals scrap can be a significant waste stream, it is typically managed separately from municipal solid waste through specialized recycling programs or facilities.

**Other Examples:**

a) **Batteries:**
- Batteries are considered a hazardous waste and should not be disposed of in regular household waste.
- They contain toxic chemicals that can be harmful to the environment if not properly handled.
- Instead, batteries should be recycled or disposed of at designated battery collection points to ensure their safe and environmentally-friendly management.

c) **Packing Materials:**
- Packing materials, such as cardboard boxes, plastic packaging, and Styrofoam, are commonly generated as waste from households, institutions, and businesses.
- These materials are considered part of municipal solid waste and can be recycled or disposed of in appropriate waste management systems.

d) **Paper:**
- Paper is one of the most common components of municipal solid waste.
- It is generated in large quantities from households, offices, schools, and other institutions.
- Paper can be recycled, reducing the need for virgin materials and minimizing the environmental impact of paper production.

In conclusion, while batteries, packing materials, and paper are examples of municipal solid waste, metals scrap is not. Metals scrap is managed separately and recycled or reused rather than disposed of as regular household waste.
