A homogenous catalytic system is developed for the synthesis of amines derivatives using amination of polyesters, including waste plastics and used cooking oils. This cobalt catalytic system is extended to carboxylic acids, esters, and vegetable oils to afford primary amines. Finally, a heterogeneous catalytic protocol was established for the transformation of alcohols and ammonia to nitriles and primary amides.
