Which of the following is NOT a category of waste generated by human beings in daily practice?

Radio-active waste.

The category of waste that is NOT generated by human beings in daily practice is Radioactive waste.

Radioactive waste is generated by nuclear power plants, nuclear weapons research, and other industrial and medical processes. It is a hazardous type of waste that must be carefully managed and disposed of to protect human health and the environment.

The other three categories of waste are all generated by human beings in daily practice:

• Biodegradable waste is waste that can be broken down by microorganisms into natural substances, such as food scraps, yard waste, and paper.
• Plastic waste is waste made from petroleum-based materials, such as plastic bags, bottles, and packaging. It is not biodegradable and can take hundreds or even thousands of years to decompose.
• Non-biodegradable waste is waste that cannot be broken down by microorganisms, such as metal, glass, and batteries.

It is important to note that all of these categories of waste can have a negative impact on the environment if they are not properly managed and disposed of. For example, biodegradable waste can pollute water and soil if it is not composted or sent to a landfill. Plastic waste can pollute oceans and rivers, and non-biodegradable waste can release harmful toxins into the environment if it is not properly disposed of.

We can all help to reduce the amount of waste we generate and protect the environment by reducing our consumption, recycling and composting whenever possible, and disposing of waste properly.
