No, it is not a pure substance because it has more than on product in it read the ingredients.
The local authorities first separates out the the products or things that can be recycled from the solid waste .Then the products which can be recycled allowed to go through degradation and then they are turned or changed into product of same material.

it would be physical change because physical change is when the substance stays the same

the flat worm gets rid of waste through the same openinig takes in food
They occur at the same temperature for a given substance just depends which direction the heat is flowing (up in the product or out into the surrounding area/substance).
The product of (frequency) times (wavelength) is always the same number,as long as the waves stay in the same substance. That number is the speedof the waves through the substance.

Not necessarily. This only happens in decomposition reactions, where energy reacts to break apart a compound. In, say, a synthesis reaction, sodium and chlorine combine, but don't leave a waste product. A physical change differs from a chemical change in that the product is the same substance, while in a chemical change it forms a/some different substance. Think about ripping a sheet of paper-is it still paper? If you burn the sheet of paper-is it still paper
