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

Radio-active waste.

The correct answer is Option (1) -Radioactive 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:

• Bio-degradable waste: This includes organic waste that can be broken down naturally by microorganisms. Examples include food scraps, garden waste, and paper.

  Plastic waste: This refers to waste made from plastic materials, which are commonly used in packaging, containers, and various household products. Plastic waste is a significant environmental concern due to its long decomposition time.

  Non-biodegradable waste: This includes waste materials that do not decompose naturally or take an exceptionally long time to do so. Examples include metals, glass, and certain types of plastics.

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.
