False.

Explanation: Low-temperature heat can still be converted to work if there is a lower-temperature sink (a temperature difference is required). However the maximum fraction convertible is limited by Carnot efficiency and becomes small as the temperature difference decreases. If the heat is irreversibly dissipated with no available colder sink, then it cannot be recovered for work.
