Which of the following is an example of non-hazardous construction waste?

In the context of construction waste, non-hazardous waste typically refers to materials that do not pose a risk to human health or the environment when managed properly. Among the options provided, plastics are categorized as non-hazardous construction waste because they do not emit harmful pollutants or have hazardous characteristics once they have been disposed of.

Plastics used in construction, such as polyethylene, PVC, and other polymers, can be recycled and reused, contributing to a more sustainable construction industry. They are less likely to leach toxic substances compared to some materials, particularly when compared to hazardous waste, which can include things like certain metals or contaminated materials.

In contrast, wood, concrete, and metal can sometimes be associated with hazardous properties depending on their treatment, location of use, and disposal methods. For example, wood can be treated with chemicals or preservatives that might pose hazards if not disposed of correctly. Concrete can also become a concern if it contains hazardous substances or if it is mixed with other materials that may be harmful. Metal can also be classified as hazardous if it has come into contact with toxics or if it contains elements that could leach into the environment.

This classification helps contractors manage waste more effectively and comply with local environmental regulations regarding waste disposal and
