yes heat is a waste product
Heat
In a normal hydrogen oxygen fuel cell, the waste products are water, and heat
Light energy is often considered a waste of energy when burning a candle because not all of the energy produced through combustion is transferred as useful light. Some of the energy is lost as heat and sound.
The by-product of metabolism is carbon dioxide, which is exhaled by the lungs as waste product. Some metabolites are also filtered and excreted by the kidneys in the form of urine. Additionally, heat is generated as a by-product of metabolism.
The only waste product from cellular respiration is carbon dioxide.

The waste product of fuel cells is typically water and heat. When hydrogen is used as the fuel source, the only byproducts are water vapor and heat, making fuel cells a very clean and efficient energy source.
waste heat is heat that is wasted, like cars waste 75% of heat
waste heat
Oxygen comes out as waste product in plants during photosynthesis
A fusion reaction generates helium as a waste product.

Carbon dioxide is the waste product exhaled from the lungs during respiration.
Waste Product
An example of waste heat is the heat produced by a car engine that is expelled through the exhaust system. This heat is a byproduct of the engine's operation and is not used to perform any useful work within the system.
The by-product of metabolism is carbon dioxide, which is exhaled by the lungs as waste product. Some metabolites are also filtered and excreted by the kidneys in the form of urine. Additionally, heat is generated as a by-product of metabolism.
