according to me,CO2 is not a waste substance because plants need it for photosynthesis.
Additional answer
This where we have to define 'waste'. I suggest it's a substance that is formed in a process and not required further. So, I think CO2 IS a waste product in the case of animals, also in the case of many plants (because their respiration produces it), although I agree that green plants do use it in photosynthesis.
Carbon dioxide is a substance produced during respiration and excreted by the body. It is a waste product that is expelled from the lungs when we exhale.
The waste products of a chemical reaction depend on the specific reaction taking place. Common waste products include water, carbon dioxide, and various inorganic salts or byproducts. Chemical reactions strive to minimize waste and maximize the conversion of reactants into desired products.
The waste product of the Krebs cycle is carbon dioxide (CO2). CO2 is produced during the process of cellular respiration as a byproduct of the oxidation of acetyl-CoA molecules.
Carbon dioxide is released from your lungs during exhalation as a waste product of respiration. It is not a waste product from the organs of excretion.
When carbonates react with acids, they produce carbon dioxide gas, water, and a salt.
For humans, the waste substance is carbon dioxide.
Burning (combustion) of organic substance will produce waste Carbon Dioxide. Also metabolic processes in living things produces waste Carbon Dioxide.
Carbon dioxide
Carbon dioxide is the waste substance that is exhaled when you breathe out. When you exhale, your body releases carbon dioxide that is produced during the process of converting the oxygen you breathe in into energy.
carbon dioxide
Carbon dioxide is a pure substance that is a compound.
Carbon dioxide is the waste substance that is transported back to the lungs from the cells in the body. It is exhaled out as a waste product of cellular respiration.

One waste product of cellular respiration is carbon dioxide.
Carbon dioxide (CO2) is a compound and can be also a pure substance.
