Are animal fats cooked with dairy issur hanaah

According to Leviticus 7:24 forbidden fats from non shechita’d animals may be used for any purpose but eating. Therefore, is it permissible to cook them with dairy and/or sell them mixed with dairy? Or is that still issur hanaah despite this Passuk saying it can be used for non eating purposes? What is the Halacha regarding this?
