The garbage output signals get recycled indefinitely. Only the useful output ever needs to generate heat.

It was thought for some time that they needed be turned to heat, but that's actually untrue. Using quantum gates, it is possible to do an arbitrary classical computation and recycle the anciliary bits.

Neat! Any reference you could share for me to read more?

There is a short but sufficient Wikipedia article on it - it is called uncomputation : https://en.wikipedia.org/wiki/Uncomputation?wprov=sfla1

The textbook I used in my quantum computing class dealt with the subject far better, but unfortunately it's not public yet :/
