to understand your doubt first you should know that what is a physical change and what is a chemical change in fact if you know that , in chemical change new substances form and a product is released as waste while in physical change no substance is formed and no product is released as waste.
If you talk about caring of people know new substance is formed and no waste is produced... But if you see, burning of paper it produces a new substance Ash and smoke is the waste produced by burning..

So I hope my answer helped you....
Thanks
