A composition includes a polymer, a functional component, and an oxidation catalyst. The functional component may be an oxidizable additive or a precursor thereof. The oxidizable additive includes an organic moiety including a first carbon atom (C1) attached to a hydrogen (H), a first group having a conjugated unit (a double bond, a triple bond, an aromatic ring); a second group having a heteroatom (including C=N, N=O, C=O, an O, a N, a fragment having at least three heteroatoms (including a N) within a spatial distance of 4Å from C1); and a third group (hydrogen, alkyl group, aromatic group, a double bond, a triple bond, and a heteroatom). The C1 may be attached to a strong mesomeric electron-donating group and a strong mesomeric electron-withdrawing group; or to a conjugated group and a mesomeric group. The functional component may be derived from a recycled plastic article.
