\textbf{Abstract:} We describe the group K0 in the case of a topological dynamical system
arising from a primitive aperiodic non-proper substitution. More generally, we can
associate a topological dynamical system to a non-properly ordered Bratteli diagram
and compute its K0 directly from the diagram. This generalizes results of Herman,
Putnam and Skau.\vspace{\fill}
