Given below are two statements:
Statement I: The non bio-degradable fly ash and slag from steel industry can be used by cement industry.
Statement II: The fuel obtained from plastic waste is lead free.
In the light of the above statements, choose the most appropriate answer from the options given below:

We need to evaluate both statements about industrial waste management.

Statement I: The non bio-degradable fly ash and slag from steel industry can be used by cement industry.

This is CORRECT. Fly ash (from thermal power plants) and blast furnace slag (from steel industry) are commonly used as supplementary cementitious materials in the cement industry. Fly ash is used in Portland Pozzolana Cement (PPC), and slag is used in Portland Slag Cement (PSC). This is a well-established practice of industrial waste utilization.

Statement II: The fuel obtained from plastic waste is lead free.

This is CORRECT. When plastic waste is converted into fuel through pyrolysis, the resulting fuel is free from lead. Unlike conventional leaded fuels (which contained tetraethyl lead as an additive), the fuel derived from plastics does not contain lead compounds, making it a cleaner alternative in that regard.

Since both statements are correct:

The correct answer is Option A: Both Statement I and Statement II are correct.
